One Faith Across the Ancient World

What did Christians understand the heart of their faith to be before the great councils of the fourth century? What should that shared faith mean for us now?

That is not merely a historical question. Christians today belong to many churches and traditions, and our disagreements are real. Yet beneath those disagreements stands a common confession: one God, the Father and Creator; Jesus Christ, his Son, who truly entered human life, suffered, died, rose, ascended, and will return; the Holy Spirit; the resurrection of the dead; the judgment to come; and the call to live in holiness and love.

My purpose in presenting these passages is to let that center become visible again. Christians should be able to recognize one another around it and begin to see ourselves, across our divisions, as one church called to a common faith and a common life.

A critic or nonbeliever should also be able to see exactly what Christianity asks a person to believe. The question is not simply whether these ideas later became orthodox doctrine. The deeper question is why the first Christians believed them and what evidence supports them. The writers studied here help establish the continuity and geographical spread of the confession. They then direct us backward toward the first-century sources where its historical claims must be examined.

Three writers give us especially substantial accounts: Irenaeus in Lyons in Roman Gaul, Tertullian in Carthage in North Africa, and Origen in Alexandria in Egypt. Their writings take us across the northern and southern shores of the Mediterranean during the late second and early third centuries.

They do not use identical wording or settle every theological question in the same way. They do preserve a recognizable account of God, Jesus Christ, the Holy Spirit, salvation, resurrection, judgment, and Christian conduct.

The passages deserve room to speak for themselves. As we read them, three questions should remain before us:

  1. What central faith do these writers share?
  2. How does that faith connect with the New Testament and the first-century church?
  3. What should it produce in Christians who confess it today?

Irenaeus in Gaul: The Faith the Church Received

Around AD 180, Irenaeus wrote Against Heresies while serving as bishop of Lyons in Roman Gaul, modern Lyon in France. His own background connected him with Asia Minor, where he had heard Polycarp.

His concern was that rival teachers were changing the identity of the Christian message. Some distinguished the Creator from the highest God; others offered elaborate accounts of divine beings or denied essential aspects of Christ’s humanity. Irenaeus answered by setting out the faith he understood the churches to have received.

As you read, notice both the beliefs Irenaeus names and the life he says those beliefs require.

“The church, although scattered throughout the whole world, even to the ends of the earth, has received this faith from the apostles and their disciples:

She believes in one God, the Father Almighty, who made heaven and earth and the sea and everything in them;

and in one Christ Jesus, the Son of God, who became human for our salvation;

and in the Holy Spirit, who announced through the prophets God’s saving arrangements, the comings of Christ, his birth from a virgin, his suffering, his resurrection from the dead, and the bodily ascension into heaven of our beloved Lord, Christ Jesus.

The Spirit also announced his coming from heaven in the Father’s glory to bring all things together under one head and to raise the whole human race bodily from the dead. Then, according to the will of the invisible Father, every knee in heaven, on earth, and under the earth will bow to Christ Jesus, our Lord and God and Savior and King, and every tongue will confess him.

He will judge everyone justly. He will send the evil spiritual powers, the angels who transgressed and rebelled, and the ungodly, unrighteous, wicked, and profane among humanity into everlasting fire.

But in his grace he will grant immortality to the righteous and holy, to those who have kept his commandments and persevered in his love, some from the beginning and others from the time of their repentance. He will surround them with everlasting glory.”

Irenaeus of Lyons, Against Heresies 1.10.1, c. AD 180

This is a substantial confession. The Creator is the Father of Jesus Christ. The Son truly enters human life for salvation. The Spirit speaks through the prophets. Christ suffers, rises, ascends, and will return. Human beings face resurrection and judgment.

The ending also belongs to the confession. Irenaeus connects the hope of immortality with God’s grace, repentance, obedience, and perseverance in love. The faith has consequences for how a person lives.


Irenaeus Names the Regions Sharing This Faith

Irenaeus immediately explains how widely this confession is shared. His geographical claim is part of the passage itself:

Listen especially for the regions he names and for his repeated insistence that the churches share one faith.

“As I have already said, the church has received this proclamation and this faith. Although scattered throughout the whole world, she carefully preserves it as though she lived in a single house. She believes these things as though she had one soul and the same heart. She proclaims them, teaches them, and hands them on in harmony, as though she had one mouth.

Although the languages of the world differ, the meaning of the tradition is one and the same. The churches established in the German regions do not believe or hand down anything different. Neither do those in Spain, Gaul, the East, Egypt, Libya, or the central regions of the world.

Just as the sun, God’s creation, is one and the same throughout the whole world, so the proclamation of the truth shines everywhere and enlightens everyone willing to come to a knowledge of the truth.

No leader of the churches, however gifted in speaking, will teach something different from these things, for no one is greater than the Master. Nor will someone who lacks the ability to express himself well damage the tradition.

Since the faith is always one and the same, someone who can explain it at great length does not add to it, and someone who can say only a little does not diminish it.”

Irenaeus of Lyons, Against Heresies 1.10.2, c. AD 180

A bishop writing in Gaul names communities across Europe, the eastern Mediterranean, and North Africa. Their languages differ, but he says their confession remains recognizable.

His final observation is particularly helpful. An eloquent teacher can explain the faith at length, while another Christian may struggle to express it. Their unequal ability does not require an unequal faith. Understanding can grow without giving the most articulate person a different Christianity.

Irenaeus is describing the churches he recognizes as preserving apostolic teaching. His argument does not establish that everyone claiming the Christian name agreed with him; the existence of his book makes the disputes plain. It does give us an explicit ancient claim that this confession belonged to a geographically widespread fellowship.


Tertullian in Carthage: The Rule of Faith Stated Directly

Around AD 200, Tertullian wrote in the Christian setting of Carthage, in what is now Tunisia. Here we encounter a Latin-speaking Christian writer on the southern shore of the Mediterranean.

In Prescription Against Heretics, he uses the expression “rule of faith” and explains exactly what he means:

As you read, compare its structure with Irenaeus: Creator, Son, incarnation, Spirit, resurrection, return, and judgment.

“Now, concerning the rule of faith, so that we may acknowledge at this point what it is we defend, you should know that it requires this belief:

There is only one God, and he is none other than the Creator of the world. He brought everything into being from nothing through his own Word, sent forth before all things.

This Word is called his Son. Under the name of God, he appeared in different ways to the patriarchs and was continually heard through the prophets. Finally, he was brought by the Spirit and power of the Father into the Virgin Mary, became flesh in her womb, and was born from her as Jesus Christ.

He then preached the new law and the new promise of the kingdom of heaven and performed miracles. He was crucified and rose again on the third day. He ascended into heaven and sat at the Father’s right hand. In his place, he sent the power of the Holy Spirit to guide those who believe.

He will come in glory to bring the saints into the enjoyment of everlasting life and the heavenly promises, and to condemn the wicked to everlasting fire. This will take place after both groups have been raised from the dead and their bodies restored.

This rule, as we will demonstrate, was taught by Christ. Among us it raises no questions except those introduced by heresies, which make people heretics.”

Tertullian, Prescription Against Heretics 13, c. AD 200

The resemblance to Irenaeus is easy to recognize, even though the wording differs. The same Creator, Son, incarnation, resurrection, Spirit, return, and judgment hold the account together.

Tertullian’s closing sentence is forceful. He is defending the boundaries of the faith against rival teachings. We should hear that force without overlooking what he actually places within the rule: a connected account of God’s action through Christ and the future awaiting humanity.


Tertullian Describes a Unity People Could Experience

Later in the same work, Tertullian explains how he understands this faith to have traveled from Christ through the apostles into the churches.

His opening temporarily sets aside the disputed descriptions of Christ so that he can ask where Christ’s own teaching was handed down. The chapter then moves from transmission to practical fellowship:

Notice that for Tertullian one faith produces a visible unity: peace, brotherhood, and hospitality among the churches.

“Christ Jesus our Lord, who will, I hope, bear with me for a moment in speaking this way, whoever he is, of whatever God he is the Son, of whatever nature he is as man and God, whatever faith he teaches, and whatever reward he promises, himself declared these things while he lived on earth.

He declared what he was, what he had been, what the Father’s will was that he was carrying out, and what human duty he was prescribing. He did this either openly before the people or privately with his disciples. From among them he had chosen twelve to remain beside him, and he appointed them to become teachers of the nations.

After one of these had been removed, he commanded the other eleven, as he departed to the Father, to go and teach all nations, baptizing them into the Father and the Son and the Holy Spirit.

The apostles, whose name means ‘those who are sent,’ immediately acted accordingly. On the authority of a prophecy in a psalm of David, they chose Matthias by lot as the twelfth apostle in Judas’s place. They received the promised power of the Holy Spirit for miracles and speech. After first bearing witness to faith in Jesus Christ throughout Judea and establishing churches there, they went out into the world and proclaimed the same teaching of the same faith to the nations.

In the same way, they established churches in every city. From these churches, all the other churches, one after another, received the tradition of the faith and the seeds of teaching. They continue to receive them every day so that they may become churches. For this reason they too can be regarded as apostolic, because they are the offspring of apostolic churches. Everything must be classified by tracing it back to its origin.

Therefore, although the churches are so numerous and so great, they comprise the one original church founded by the apostles, from which they all come. In this way, all are original and all are apostolic.

Their unity is demonstrated by their peaceful fellowship, by calling one another brothers, and by the bond of hospitality. These relationships are governed by no other rule than the single tradition of the same sacred mystery.”

Tertullian, Prescription Against Heretics 20, c. AD 200

Tertullian describes a network of churches connected by a received message. The communities become recognizable as one through fellowship, brotherhood, and hospitality.

That is a demanding account of unity. Christians receive one another, acknowledge one another as family, and open their lives to one another. Agreement takes a social form.

His account also reminds us that these witnesses were connected. We are looking at a faith transmitted through relationships among churches, rather than at isolated communities independently arriving at the same ideas.


Origen in Alexandria: A Received Faith and Questions Still Open

Our third witness takes us east along the North African coast to Alexandria in Egypt.

Origen wrote On First Principles around AD 220 to 230, during his Alexandrian period. Its preface explains what he understands the church to have received and what he believes still requires investigation.

Origen begins by acknowledging disagreement:

As you read, notice his controlling distinction: some teachings have been clearly handed down to the whole church, while other questions remain open to investigation.

“Many who profess to believe in Christ differ from one another, not only in small and minor matters, but also on subjects of the greatest importance: God, the Lord Jesus Christ, and the Holy Spirit. They also disagree about created beings, including the heavenly powers and holy spiritual forces.

It therefore seems necessary first to establish a definite boundary and a clear rule concerning these matters, and then to proceed to the investigation of other questions.

Once we believed that Christ was the Son of God and became convinced that we must learn the truth from him, we stopped looking for it among those who attached the name of truth to mistaken opinions, despite the claims made by many Greeks and non-Greeks.

Likewise, many people think they hold the teaching of Christ, yet some differ from those who came before them. But the church’s teaching, handed down in an orderly succession from the apostles and continuing in the churches to the present day, is still preserved. Therefore, only that teaching should be accepted as true which does not differ in any respect from the tradition of the church and the apostles.

We should understand that, when the holy apostles preached faith in Christ, they spoke with the greatest clarity about certain matters they considered necessary for everyone, even for those who were less capable of investigating divine knowledge.

They left the reasons underlying these teachings to be examined by those who would receive the outstanding gifts of the Spirit, especially those who, through the Holy Spirit himself, would receive gifts of speech, wisdom, and knowledge.

On other subjects, they stated only that certain things exist, while remaining silent about how they exist or where they originated. They clearly intended that the more diligent of their successors, who love wisdom, should have matters on which to exercise their abilities and show their fruit. I mean those who prepare themselves to become fit and worthy recipients of wisdom.”

Origen of Alexandria, On First Principles, preface 2–3, c. AD 220–230

Origen does not mistake the existence of disagreement for the absence of a received faith. He proposes beginning with what has been handed down and then investigating further.

He also distinguishes believing a teaching from possessing a complete explanation of it. A person may confess the faith before being able to answer every question someone could ask about it.


Origen Sets Out the Teaching and Its Unanswered Questions

Origen’s account is longer than the previous summaries. It includes both the teachings he regards as established and questions he believes remain unresolved. Reading it in full allows us to see where he draws those distinctions.

The essential phrases are “clearly handed down” and “not clearly stated.” They show us the boundary Origen sees between the shared faith and matters Christians may continue to examine.

“The particular matters clearly handed down in the teaching of the apostles are these:

First, there is one God who created and ordered everything. When nothing existed, he brought all things into being. He has been God from the first creation and foundation of the world. He is the God of all the righteous: Adam, Abel, Seth, Enosh, Enoch, Noah, Shem, Abraham, Isaac, Jacob, the twelve patriarchs, Moses, and the prophets.

In these last days, as he had previously announced through his prophets, this God sent our Lord Jesus Christ to call Israel to himself first, and then the Gentiles after the unfaithfulness of the people of Israel.

This just and good God, the Father of our Lord Jesus Christ, himself gave the law, the prophets, and the Gospels. He is also the God of the apostles and of the Old and New Testaments.

Second, Jesus Christ himself, who came into the world, was begotten from the Father before all created things. He served the Father in the creation of everything, for all things were made through him. In the last times he emptied himself and became human. Although he was God, he took flesh; and when he became human, he remained the God he was.

He took a body like our own, differing only in that it was born from a virgin and the Holy Spirit. This Jesus Christ was truly born and truly suffered. He did not merely appear to undergo the death common to humanity, but truly died. He truly rose from the dead, spoke with his disciples after his resurrection, and was taken up into heaven.

Third, the apostles taught that the Holy Spirit is joined with the Father and the Son in honor and dignity. But whether he should be understood as begotten or unbegotten, or whether he should also be called a Son of God, is not clearly distinguished. These matters must be investigated from sacred Scripture as carefully as we are able.

It is, however, very clearly taught throughout the churches that this Spirit inspired each of the holy people, whether prophets or apostles. There was not one Spirit in the people of the old covenant and a different Spirit in those inspired at Christ’s coming.

After these matters, apostolic teaching also holds that the soul has an existence and life of its own. After leaving this world, it will receive what it deserves: an inheritance of eternal life and blessedness if its deeds have obtained this, or eternal fire and punishment if the guilt of its offenses has brought it to that end.

There will also be a resurrection of the dead. This body, now sown in decay, will rise free from decay; and what is sown in dishonor will rise in glory.

The church’s teaching also clearly establishes that every rational soul possesses free choice and will. It must struggle against the devil, his angels, and hostile powers, because they try to weigh it down with sins. But by living rightly and wisely, we should strive to free ourselves from that burden.

It follows that we do not regard ourselves as subject to a necessity that forces us, even against our will, to do either good or evil. Since we have control over our choices, some influences may urge us toward sin and others may help us toward salvation, but no necessity forces us to act rightly or wrongly.

Those who say that the courses and movements of the stars cause human actions think otherwise. They attribute to the stars not only events beyond our freedom of choice, but also actions that lie within our own power.

As for the soul’s origin, however, the church’s teaching does not explain it with sufficient clarity. Is it passed on through human seed, so that its essential nature is contained in the bodily seed itself? Or does it have some other beginning? Does that beginning involve generation, or not? Is the soul introduced into the body from outside, or not? These matters have not been clearly distinguished.

Concerning the devil, his angels, and the hostile powers, the church’s teaching establishes that these beings exist. But it does not explain clearly enough what they are or how they exist.

Most hold the view that the devil was an angel who rebelled and persuaded as many other angels as possible to fall away with him. Those beings continue to be called his angels.

The church also teaches that the world was made, that it began at a particular time, and that it will be destroyed because of its wickedness.

But what existed before this world, or what will exist after it, is not certainly known to most people, because the church’s teaching contains no clear statement about it.”

Origen of Alexandria, On First Principles, preface 4–7, c. AD 220–230

The central confession remains recognizable. Yet Origen also preserves uncertainties that later Christians may find surprising, especially concerning the Holy Spirit. We should allow those differences to remain visible. His account belongs to the early third century, before the later councils gave more precise definitions.

Notice also the difference between his confidence in moral responsibility and his uncertainty about the soul’s origin. He does not need to settle every question about how a soul comes into existence before insisting that human beings are responsible for their actions.

He continues with Scripture, spiritual beings, and the work of theological investigation:

“Finally, the Scriptures were written through the Spirit of God. They have not only the meaning apparent at first sight, but also another meaning that escapes most readers. The written words give form to sacred mysteries and represent divine realities.

The whole church agrees that the entire law is spiritual. But the spiritual meaning it conveys is not known to everyone, only to those who receive the grace of the Holy Spirit in words of wisdom and knowledge.

The term ‘incorporeal,’ meaning ‘without a body,’ is unfamiliar and unused in many other writings and also in our own Scriptures.

Someone might quote it from the little work called the Teaching of Peter, in which the Savior appears to say to his disciples, ‘I am not an incorporeal demon.’ My first reply is that this work is not included among the church’s books. We can show that it was not composed by Peter or by any other person inspired by God’s Spirit.

But even if that point were conceded, the word ‘incorporeal’ there would not have the same meaning it has when Greek and pagan philosophers discuss a nature without a body.

In that little work, the expression ‘incorporeal demon’ refers to a demonic body whose form or appearance, whatever it may be, differs from our dense and visible bodies. The author’s meaning must be understood as saying that Jesus did not have the kind of body demons have, naturally fine and thin, as though made of air, which is why many people consider or call it incorporeal. Instead, he had a solid body that could be touched.

In ordinary speech, people without specialized knowledge call things incorporeal when they do not have this solid character. Someone might, for example, call the air we breathe incorporeal because it cannot be grasped and held or offer resistance to pressure.

We must investigate whether what Greek philosophers call ‘incorporeal’ appears in holy Scripture under another name.

We must also investigate how God himself should be understood: whether as having a body and a particular shape, or as having a nature different from bodies. This point is not clearly stated in our teaching. The same questions must be asked concerning Christ, the Holy Spirit, every soul, and everything possessing a rational nature.

The church also teaches that there are angels of God and good spiritual powers who serve him in accomplishing human salvation. But when they were created, what their nature is, and how they exist are not clearly stated.

Nor is there a definite teaching about whether the sun, moon, and stars are living beings or have no life.

Anyone who wishes to form an ordered and connected account of these truths must therefore begin with elements and foundations such as these, following the command, ‘Enlighten yourselves with the light of knowledge.’

Through clear statements and sound reasoning, such a person should seek to establish the truth concerning each subject and bring it into one body of teaching. This should be done through illustrations and arguments found in holy Scripture or reached by carefully tracing their consequences and following a sound method.”

Origen of Alexandria, On First Principles, preface 8–10, c. AD 220–230

Some of these questions belong to an ancient intellectual world that feels unfamiliar today. Their presence helps us see what Origen is doing. He begins with received teaching, identifies uncertainties, and invites disciplined investigation.

He does not place every proposed explanation on the same level as the confession itself.


The Same Center Is Already Visible in the First Century

Irenaeus, Tertullian, and Origen did not create this faith in the late second or early third century. Its central claims are already present in the earliest Christian writings.

The seven letters most widely accepted as genuinely written by Paul are Galatians, 1 Thessalonians, 1 and 2 Corinthians, Romans, Philippians, and Philemon. They take us into the first century, beginning within roughly two decades of Jesus’ death. More importantly, Paul sometimes identifies material that he himself had previously received.

The clearest example is his summary of the resurrection proclamation:

“I handed on to you, as of first importance, what I had also received: that Christ died for our sins in accordance with the Scriptures, that he was buried, that he was raised on the third day in accordance with the Scriptures, and that he appeared to Cephas and then to the Twelve.

After that, he appeared to more than five hundred brothers and sisters at one time, most of whom were still alive, though some had died. Then he appeared to James, then to all the apostles, and last of all he appeared also to me.”

First Corinthians 15:3–8, c. AD 54–55

Paul distinguishes between composing an argument and handing on something he had received. That takes the resurrection proclamation earlier than the letter itself.

The larger structure found in the rule of faith is also distributed throughout these first-century letters:

Central beliefFirst-century evidence
One God, the Father and CreatorFirst Corinthians 8:6
Jesus Christ as Son and LordRomans 1:3–4; First Corinthians 8:6; Philippians 2:6–11
Christ’s real human life and deathRomans 1:3; Galatians 4:4; First Corinthians 2:2; Philippians 2:7–8
Christ’s burial, resurrection, and appearancesFirst Corinthians 15:3–8
The Holy Spirit active in believers and the churchRomans 8:9–17; First Corinthians 2:10–13; 12:3–13; Galatians 3:1–5
Christ’s return and the resurrection of believersFirst Thessalonians 4:13–18; First Corinthians 15:20–28, 35–57
Future judgment according to how people have livedRomans 2:5–11; First Corinthians 3:10–15; Second Corinthians 5:10
Faith expressed through love and a transformed lifeGalatians 5:6, 13–26; First Corinthians 13; Romans 12

Near the end of the first century, the church at Rome wrote to a divided church in Corinth. The letter known as First Clement appeals to what the two congregations already share:

“Why are there conflicts, anger, divisions, schisms, and fighting among you? Do we not have one God and one Christ? Is there not one Spirit of grace poured out upon us? Do we not have one calling in Christ?

Why do we divide and tear apart the members of Christ and rebel against our own body? Have we reached such madness that we have forgotten that we are members of one another?”

Church at Rome, traditionally associated with Clement, First Letter to the Corinthians 46.5–7, c. AD 96

This is especially important for the purpose of this article. The shared confession is not presented merely as a list of correct beliefs. One God, one Christ, one Spirit, and one calling make division within Christ’s body intolerable.

The first-century evidence does not contain one complete document identical to the later rule of faith. It contains the beliefs from which that rule is formed. By the time Irenaeus, Tertullian, and Origen explain the faith at greater length, they are organizing convictions already present in the earliest sources.


Judgment Is Part of the Core Christian Confession

The rule of faith does not end with Christ’s resurrection. It moves toward his return, the resurrection of humanity, and judgment. That theme appears in all three principal witnesses.

Irenaeus says that Christ will return, raise humanity, judge justly, and grant immortality to those who have persevered in holiness and love. Tertullian speaks of Christ bringing the saints into everlasting life and condemning the wicked after the resurrection of both. Origen says that each soul will receive a future corresponding to its deeds and insists that human beings possess genuine moral responsibility.

None of them treats Christians as exempt from moral judgment simply because they identify as Christians. The same point appears in the New Testament.

“God will repay each person according to what that person has done. To those who persevere in doing good, seeking glory, honor, and immortality, he will give eternal life. But for those who are self-seeking, rejecting the truth and following wrongdoing, there will be wrath and anger.

There will be suffering and distress for everyone who does evil, first for the Jew and also for the Greek; but glory, honor, and peace for everyone who does good, first for the Jew and also for the Greek. For God shows no partiality.”

Romans 2:6–11, c. AD 57

Paul later speaks directly to Christians:

“All of us must appear before Christ’s judgment seat, so that each person may receive what is due for what was done in the body, whether good or evil.”

Second Corinthians 5:10, c. AD 55–56

This does not require us to deny grace or imagine that human beings save themselves through moral achievement. Paul also speaks emphatically of grace, faith, and God’s saving action in Christ. But grace does not make our lives irrelevant. The same Paul describes what counts as “faith working through love” and warns Christians not to use freedom as an opportunity for self-indulgence.

Judgment therefore belongs to the center of Christian faith, not to an optional appendix. It gives seriousness to self-examination, repentance, perseverance, and holiness. It also gives seriousness to charity. How we treat other people is not disconnected from what we confess about Christ.

This is one reason Christian unity cannot mean merely agreeing to a short list of doctrines. The shared confession calls one people into a shared life. We will answer to the same Lord for what we have done with the faith we profess.


What About the Apostles’ Creed?

Readers who know the Apostles’ Creed will recognize the resemblance immediately: God the Father, Jesus Christ his Son, the Holy Spirit, Christ’s birth and suffering, his resurrection and return, and the hope of our own resurrection.

The connection is real, but the dates require care. The familiar Apostles’ Creed developed from an older confession associated with the church at Rome, commonly called the Old Roman Creed or Old Roman Symbol.

CreedLocationDateAuthorship
Old Roman CreedRome, ItalyA Greek form appears in Marcellus of Ancyra’s profession of faith, c. AD 340–341; Rufinus discusses the Roman form in the early fifth century. Its earlier development is less securely dated.No individual composer is known. Marcellus and Rufinus are witnesses to the text, not its established authors.
Apostles’ CreedDeveloped in the Latin-speaking Western churches from the older Roman confessionIts familiar full form is attested by the eighth century, following several centuries of development.No individual author is known. The title expresses its claim to preserve apostolic teaching.

Despite its name, we cannot establish that the twelve apostles personally composed the Apostles’ Creed. Rufinus recounts a tradition that they jointly produced a confession before departing to preach, but his account comes centuries after their lifetime. It does not establish their authorship of the received text.

Nor should we assume that Irenaeus, Tertullian, and Origen were quoting the familiar Apostles’ Creed word for word. Their writings are earlier than that creed’s completed form. The resemblance shows how much of the confession’s substance was already present in the faith they describe.

This distinction strengthens the historical point. We can read the shared content directly in writings from Gaul, Carthage, and Alexandria without projecting a later text backward into their period. The older Roman tradition adds Rome to the geographical picture, although its surviving forms must be dated on their own evidence.

The Apostles’ Creed is therefore a useful point of recognition for readers. Its familiar wording helps us recognize the older pattern, while the passages from these three authors let us examine that pattern in their own places, dates, and words.


What These Three Witnesses Allow Us to See

The geographical span is substantial: Irenaeus writes from Lyons in Gaul, modern France; Tertullian from Carthage, modern Tunisia; and Origen from Alexandria in Egypt. These are distinct regions across the northern and southern shores of the Mediterranean. Irenaeus also explicitly names churches across the German regions, Spain, the East, Egypt, and Libya as sharing the faith he describes.

Their accounts preserve a common structure across different settings. The God who created the world is the Father of Jesus Christ. The Son truly became human, suffered, died, and rose. The Holy Spirit belongs to the life and teaching of the church. Human beings face resurrection and judgment, and their conduct matters.

Their statements are not identical. Origen includes questions and distinctions that do not appear in the shorter summaries. Nor were these men offering a neutral survey of everyone who claimed to be Christian. They were defending what they understood to be the apostolic inheritance.

Those qualifications help us describe the evidence accurately. A recognizable confession was being articulated across distant regions well before Christianity received imperial sponsorship. That establishes age, continuity, and geographical spread. It does not, by itself, prove that Jesus rose from the dead or that the Christian account of God is true.

For that question, the investigation must move backward. What can be established from the seven undisputed letters? How early is the tradition Paul says he received? What explains the conviction of Peter, James, Paul, and the other named witnesses that Jesus had appeared to them alive? The rule of faith tells the critic what Christianity claims; the first-century evidence is where the historical case for its central event must be tested.

For a critic, that clarity matters. Before someone can fairly judge Christianity, the Christian message needs to be stated plainly enough to be understood.

For Christians, these passages raise a different question. If believers in different traditions confess this same central faith, can we begin to see ourselves again as one church? That does not erase every theological or institutional division. It does mean those divisions should not be allowed to hide the deeper unity already given in one God, one Christ, one Spirit, one hope, and one coming judgment.

Tertullian’s answer includes peace, brotherhood, and hospitality. Agreement should become visible in how we receive and help one another.

The personal demand is just as clear. Irenaeus speaks of repentance, obedience, and perseverance in love. Origen insists upon moral responsibility. The faith we confess gives us reason to examine our own lives honestly.

For me, these belong together: a Christianity that a critic can understand, a confession around which Christians can recognize one another, and a life directed toward holiness and charity.

That means asking whether my faith is making me more truthful, more willing to repent, and more faithful when obedience is costly. It also means asking whether the stranger, the hungry person, and the suffering neighbor experience anything of that faith through my actions.

The rule of faith gives the critic something definite to examine and Christians something definite around which to unite. It points backward to the first-century proclamation that must be tested and forward to the judgment before which every life will be revealed.

The challenge is not only to repeat the confession. It is to become one church around it: a people who seek truth honestly, repent seriously, pursue holiness, welcome one another, and make their faith visible through love.

Paul Would Not Put Words in Jesus’ Mouth

Anyone inventing a religion has an obvious advantage: the founder can be made to answer every question.

When a difficult problem arises, the writer can simply place a convenient command on the founder’s lips. A disputed marriage, a financial disagreement, a disorderly worship service, or a new moral controversy can all be settled with the same claim: “The Lord said.”

That is not what we find in Paul.

When Paul wrote 1 Corinthians around AD 53 to 55, he was answering questions from a troubled church hundreds of miles from Jerusalem. The Corinthians were divided over teachers, marriage, money, worship, spiritual gifts, and even the resurrection. Paul wrote with apostolic authority, and he was rarely hesitant to tell them what he believed they should do.

Yet Paul did something that is historically remarkable. He distinguished between teachings he believed came from Jesus and judgments he was making as an apostle. When he knew a command of the Lord, he appealed to it. When he possessed a tradition concerning something Jesus had done, he handed it on. When he did not know of a command from Jesus addressing the question before him, he admitted that too.

That restraint matters.

If Paul were freely inventing teachings and placing them in the mouth of Jesus, there would have been no reason for him to write, “I, not the Lord,” or to acknowledge, “I have no command from the Lord.” Those admissions suggest that the words of Jesus were not an unlimited supply of religious authority that Paul could reshape whenever the situation demanded it. They belonged to a received tradition with recognizable content and real boundaries.

This does not prove that Paul possessed one of our completed canonical Gospels. The traditions may have reached him orally, in writing, or through some combination of the two. What it does show is that by the middle of the first century, Christians were already preserving and applying specific teachings of Jesus. Paul expected churches far from Judea to recognize those teachings, and he was careful not to claim the voice of Jesus when no remembered command applied.

Five passages in 1 Corinthians allow us to watch that process at work. Three preserve clear parallels to Gospel material. Two show Paul identifying questions for which he knew no direct saying of Jesus. Together, they reveal something more important than an isolated verbal resemblance: they reveal an early Christian community already living under a body of Jesus tradition before the canonical Gospels had reached their final form.


1. “Not I, but the Lord”: Jesus’ Teaching on Divorce

The first example appears in Paul’s answer to Christians who were uncertain about marriage:

“To the married I give this command, not I but the Lord: a wife should not separate from her husband. But if she does separate, she should remain unmarried or else be reconciled to her husband; and a husband should not divorce his wife.”

1 Corinthians 7:10–11, about AD 53–55

Paul could have written simply, “I command you.” Instead, he interrupts himself to identify the source: “not I but the Lord.” He believes that the Corinthians’ question has already been addressed by Jesus.

The teaching clearly resembles what appears in the later Gospel accounts:

“Whoever divorces his wife and marries another commits adultery against her; and if she divorces her husband and marries another, she commits adultery.”

Mark 10:11–12, commonly dated about AD 65–75

Luke preserves the same central warning:

“Anyone who divorces his wife and marries another commits adultery, and whoever marries a woman divorced from her husband commits adultery.”

Luke 16:18, commonly dated about AD 80–95

Matthew gives the teaching in a somewhat different form and includes an exception related to sexual immorality in Matthew 5:32 and 19:9. Those differences matter when Christians debate the full biblical teaching on divorce, but they do not erase the common tradition. Paul and the Synoptic Gospels all know a demanding teaching from Jesus that opposes divorce and treats remarriage with great seriousness.

Paul does not quote the saying word for word, and he adds practical guidance for a couple who has already separated. That suggests he is not mindlessly copying a sentence. He is applying an established teaching to an actual crisis in Corinth. The wording can vary while the recognized source remains the same: this command came from the Lord.

That is our first positive parallel. Before the canonical Gospels had reached their final form, Paul already knew and applied a teaching attributed specifically to Jesus.


2. “The Lord Commanded”: Support for Those Who Proclaim the Gospel

The second example comes from Paul’s defense of the right of apostles and missionaries to receive material support. After appealing to ordinary labor, the law of Moses, and the practice of those who served in the temple, Paul adds one more authority:

“In the same way, the Lord commanded that those who proclaim the gospel should get their living from the gospel.”

1 Corinthians 9:14, about AD 53–55

Paul does not tell us the exact words of the command, but the closest surviving parallels appear in Jesus’ instructions to his traveling messengers. In Matthew, Jesus tells them not to carry unnecessary provisions because:

“Laborers deserve their food.”

Matthew 10:10, commonly dated about AD 80–95

Luke preserves the instruction this way:

“Stay in the same house, eating and drinking whatever they provide, for the laborer deserves to be paid.”

Luke 10:7, commonly dated about AD 80–95

Once again, Paul’s wording is not identical to either Gospel. He summarizes the principle and applies it to Christian missionaries who proclaim the Gospel. Yet he does not present the principle as something he invented. He says that “the Lord commanded” it.

It is possible to imagine several ways Paul could have received this teaching. He may have heard it from Peter, James, or other early disciples. It may have traveled through missionaries who repeated Jesus’ instructions as they entered new cities. It may even have existed in an early written collection. First Corinthians does not allow us to decide among those possibilities.

What it does allow us to say is that Paul knew a command of Jesus corresponding to a tradition later preserved in Matthew and Luke. He expected the authority of that command to matter to a congregation in Corinth, far from the villages where Jesus had originally taught.

There is another detail here that deserves notice. Paul appeals to this command while explaining a right that he has chosen not to use. He is not inventing a profitable command and then collecting the money. He believes Christian missionaries possess the right to support, but he has surrendered that right in Corinth so that no one can accuse him of preaching for personal gain.

Once again, the saying does not appear as a convenient weapon created for Paul’s benefit. It stands above him, defining a right that he is free to surrender but not to deny.


3. “I Received What I Handed On”: The Meal on the Night Jesus Was Betrayed

The third example is the most detailed. The Corinthians had turned the Lord’s Supper into another expression of their divisions. Some ate well while others went hungry. To correct them, Paul returned to the tradition he had taught them when he founded the church:

“For I received from the Lord what I also handed on to you: that the Lord Jesus, on the night when he was betrayed, took bread, and when he had given thanks, he broke it and said, ‘This is my body, which is for you. Do this in remembrance of me.’ In the same way he took the cup also, after supper, saying, ‘This cup is the new covenant in my blood. Do this, as often as you drink it, in remembrance of me.’ For as often as you eat this bread and drink the cup, you proclaim the Lord’s death until he comes.”

1 Corinthians 11:23–26, about AD 53–55

This is not merely a general belief that Jesus once shared meals with his followers. Paul knows a sequence of actions and words attached to a particular night. Jesus took bread, gave thanks, broke it, interpreted it as his body, and commanded that the act be repeated in his memory. After supper, he interpreted the cup through his blood and the covenant.

The same pattern appears in the Gospel accounts. Mark writes:

“While they were eating, he took a loaf of bread, and after blessing it he broke it, gave it to them, and said, ‘Take; this is my body.’ Then he took a cup, and after giving thanks he gave it to them, and all of them drank from it. He said to them, ‘This is my blood of the covenant, which is poured out for many.’”

Mark 14:22–24, commonly dated about AD 65–75

Luke’s version stands even closer to Paul’s wording:

“This is my body, which is given for you. Do this in remembrance of me.”

Luke 22:19, commonly dated about AD 80–95

Luke then connects the cup with “the new covenant in my blood” in Luke 22:20, just as Paul does.

Paul’s account is earlier than the completed Gospel texts according to the chronology accepted by most critical scholars. More importantly, Paul reminds the Corinthians that he had already “handed on” this tradition to them. The tradition therefore predates the letter itself and had reached Corinth during Paul’s earlier ministry there.

The phrase “received from the Lord” requires careful treatment. Some readers understand it to mean that Jesus revealed every detail of the meal directly to Paul. That remains a serious possible reading. Most interpreters, however, understand Paul to be naming the Lord as the ultimate source of a tradition that reached him through earlier Christians.

Paul repeatedly uses the paired language of receiving and handing on for tradition. At the beginning of the same chapter, he praises the Corinthians for maintaining the traditions as he delivered them in 1 Corinthians 11:2. In 1 Corinthians 15:3, he again says that he “received” and “handed on” the proclamation about Jesus’ death, burial, resurrection, and appearances.

The Lord is the ultimate source of the meal because these are presented as the Lord’s actions and words. Paul may have received the account through those who were present, through the earlier Christian community, through revelation, or through some combination of these. The text does not trace every link in the chain.

We should therefore resist claiming more than Paul gives us. First Corinthians 11 does not prove that Paul possessed a completed copy of Luke, nor does it establish that Luke copied Paul. It does establish that this account of Jesus’ final meal was circulating before either document reached its final form. By the early 50s, Christians in Corinth were already repeating these words in worship and organizing a sacred meal around them.

This was not Gospel theology waiting to be invented generations later. It was Gospel content already embedded in the life of the churches.


4. “I Have No Command from the Lord”: Paul Admits the Limit of His Tradition

The next two passages work differently. They do not preserve additional sayings of Jesus. They show what Paul does when he knows of no saying that answers the question before him.

The first concerns the “virgins,” or those who had never married, in the Corinthian congregation:

“Now concerning virgins, I have no command from the Lord, but I give my judgment as one who by the Lord’s mercy is trustworthy.”

1 Corinthians 7:25, about AD 53–55

The precise situation behind the Corinthians’ question is difficult to reconstruct. They may have been asking whether unmarried Christians should marry, whether engaged couples should complete their marriages, or whether remaining single was preferable because of the present crisis. Paul offers careful counsel, but he begins by admitting that he has “no command from the Lord.”

Jesus had spoken about people who remained unmarried for the sake of the kingdom in Matthew 19:12, but that teaching did not provide a direct ruling for the exact problem Paul was facing. Paul does not stretch a related saying until it appears to answer a question it never addressed. He identifies the limit of the tradition and then gives his own considered judgment.

This does not mean that Paul thinks his advice is careless, optional, or spiritually worthless. He describes himself as someone made trustworthy by the Lord’s mercy. He expects the Corinthians to take his judgment seriously. But he still distinguishes an apostolic judgment from a command known to have come from Jesus.

That distinction would have been unnecessary if “the Lord said” were simply a phrase Paul could use whenever he wanted to strengthen an argument. Paul has every opportunity to place his counsel directly into the mouth of Jesus, yet he refuses to do so.


5. “I, Not the Lord”: A New Question Created by the Gentile Mission

The fifth example appears in the same discussion of marriage, immediately after Paul has appealed to Jesus’ teaching about divorce:

“To the rest I say, I and not the Lord: if any brother has a wife who is an unbeliever, and she consents to live with him, he should not divorce her. And if any woman has a husband who is an unbeliever, and he consents to live with her, she should not divorce him.”

1 Corinthians 7:12–13, about AD 53–55

The situation is different from the one addressed in verses 10 and 11. Paul is now considering a marriage in which one spouse has become a Christian while the other remains an unbeliever. Should the believer leave because the marriage is spiritually mixed? Does the presence of an unbelieving spouse make the home unclean?

This was precisely the kind of problem created or greatly expanded by the Gentile mission. Men and women were not always converting at the same time. A person could accept the Gospel and then return home to a spouse who continued to worship the traditional gods.

Paul knows Jesus’ command against divorce, but he apparently knows of no surviving saying in which Jesus directly addressed this new missionary situation. He therefore marks the difference: “I, not the Lord.” He then reasons from the holiness of the believing spouse, the good of the family, and God’s call to peace.

Paul is not contradicting Jesus, and he is not dismissing his own counsel as a private opinion that the Corinthians may ignore. He is telling them where the ruling comes from. The earlier command rests on a remembered teaching of Jesus. The new application is Paul’s apostolic judgment.

That is an extraordinary piece of historical honesty. Within the same paragraph, Paul tells us where his source begins and where his own reasoning takes over.


Why These Are Five Examples, Even Though Only Three Preserve Positive Parallels

It is important to describe the evidence accurately. These are not five independent sayings of Jesus found in both Paul and the Gospels.

The first three passages are positive parallels. In 1 Corinthians 7:10–11, Paul appeals to Jesus’ teaching about divorce. In 1 Corinthians 9:14, he refers to the Lord’s command that Gospel workers may receive support. In 1 Corinthians 11:23–26, he hands on the tradition of the bread and cup from Jesus’ final night.

The last two are negative examples, but “negative” does not mean unimportant. In 1 Corinthians 7:25, Paul admits that he has no command from the Lord concerning the question before him. In 1 Corinthians 7:12–13, he explicitly identifies the ruling as his own rather than a remembered saying of Jesus.

The positive parallels show us some of the content Paul knew. The negative examples show us that the tradition had boundaries. Together, they give us something like source control inside the letter. Paul is not merely using the name of Jesus to bless every conclusion he reaches. He distinguishes inherited teaching from fresh application.

That distinction may be more historically revealing than another loose verbal similarity would have been. A person who feels free to invent the founder’s words rarely pauses to announce where the founder’s words run out.


Did Paul Possess a Written Gospel?

These passages naturally raise a larger question. If Paul could identify what Jesus had and had not commanded, did he possess something in writing?

He may have, but the evidence does not allow us to say so with certainty.

The traditions could have reached Paul orally. Ancient communities were capable of preserving teachings through repeated instruction, worship, memorization, and the regular movement of teachers between churches. Paul personally knew Peter and James, as Galatians 1:18–19 and 2:1–10 make clear, and he worked within a much larger network of apostles, missionaries, and congregations. He did not need a completed Gospel book in order to learn what Jesus’ earliest followers were teaching.

Written material is also possible. Letters, notes, collections of sayings, and partial narratives could circulate before the completion of the books that later became canonical. Paul’s own ministry shows how quickly Christian writing could travel between distant cities. Yet no passage in 1 Corinthians names a written Gospel or gives us enough information to reconstruct one.

A mixture of oral and written transmission may be closest to the world in which Paul lived. A missionary could hear a teaching, repeat it in worship, preserve part of it in notes, and pass it to another church. Oral and written communication were not rival systems. They reinforced one another.

The argument, therefore, should not be that Paul must have possessed our completed Gospel of Matthew, Mark, or Luke. The stronger and more defensible claim is that the substance of several Gospel traditions was already circulating while Paul was writing. The final evangelists did not create this material out of silence. They wrote within a movement that was already remembering Jesus’ teachings, repeating the story of his final meal, and distinguishing his commands from later apostolic judgments.

This challenges the idea of a late origin for Gospel content. It does not, by itself, overturn the usual critical dates assigned to the final forms of the Gospel books. The tradition can be earlier than the books that preserve it.


The Strongest Skeptical Response

A careful skeptic does not have to deny any of this. The skeptic can agree that Paul knew traditions about Jesus by the early 50s and still question whether Jesus actually spoke every word in exactly the form later recorded.

Oral traditions can change. Communities can reshape memories as they repeat them. Paul’s phrase “received from the Lord” might be interpreted as a claim to revelation. The later evangelists may have inherited traditions influenced by Paul, rather than preserving completely independent lines of testimony. Most importantly, evidence that Christians believed a tradition at an early date is not automatically proof that every detail of the tradition is historically exact.

A critic could therefore argue that Paul is preserving early Christian attributions to Jesus, not independently verified recordings of Jesus. On that reading, Paul’s restraint would reveal the boundaries of the tradition as he received it, but it would not prove that every saying within that tradition goes back to Jesus in its exact surviving form.

Those are legitimate cautions, and the Christian argument becomes weaker when it pretends they do not exist. These passages cannot prove a word-for-word transcript of Jesus’ teaching. They cannot identify the precise route by which each tradition reached Paul. They cannot prove from 1 Corinthians alone that Paul owned a written Gospel.

But those cautions do not make the evidence disappear.

By the early 50s, Jesus was already remembered as a teacher whose commands governed Christian conduct. A tradition about his final meal had already been taught in Corinth and incorporated into Christian worship. Paul could distinguish between commands attributed to Jesus and questions for which no such command was known. These traditions were not being introduced for the first time by a Gospel writer near the end of the first century. They were already functioning within Christian communities decades earlier.

The skeptic may continue to question how accurately the traditions preserve Jesus. What is no longer reasonable is to speak as though the speaking, teaching Jesus suddenly emerged only when the completed Gospels appeared.


Paul Did Not Invent Christianity

These passages also place an important limit on the familiar claim that Paul created Christianity.

Paul certainly shaped the movement. He interpreted the meaning of Jesus’ death and resurrection, carried the Gospel throughout the Gentile world, and answered questions that had never arisen during Jesus’ public ministry. His influence is impossible to exaggerate.

Influence, however, is not the same as invention.

Paul repeatedly describes himself as someone who received before he handed on. He knows commands that he attributes to Jesus, and those commands can overrule the preferences of the Corinthians. He knows traditions he did not create, including the sacred meal already centered on Jesus’ body, blood, death, and promised return. He also knows when the received tradition does not answer a new question, and he marks the point at which his own reasoning begins.

A creator would be free to make the central figure say whatever the new movement required. Paul does not behave as though he possesses that freedom. He interprets Jesus, applies Jesus, and argues about the meaning of Jesus, but he does not treat Jesus as an empty name into which any convenient command can be placed.

As we have already seen from Galatians, Paul also knew Peter and James and compared his Gospel with the recognized leaders in Jerusalem. The stream of Christian tradition did not begin at Paul’s writing desk. It reached him, passed through him, and continued into churches that were already learning how to remember the Lord.


A Lesson in Christian Honesty and Unity

Paul’s method should also challenge Christians.

Believers sometimes speak as though every personal conviction, denominational custom, or disputed interpretation carries exactly the same weight as a direct command of Jesus. Paul was more careful. He could say, “not I but the Lord,” when he knew a teaching of Jesus. He could also say, “I have no command from the Lord,” and then explain the judgment he believed faithfulness required.

That distinction did not weaken his authority. It made his teaching more trustworthy.

Christians should be equally willing to distinguish the center of the faith from later applications, direct teachings from reasonable conclusions, and what the text actually says from what a particular tradition has built upon it. That kind of honesty does not require us to abandon conviction. It allows us to hold our convictions without placing words in the mouth of Christ.

It also creates room for Christian unity. When the Lord has spoken, Christians should listen together. When faithful believers are reasoning through questions the Lord did not directly address, they should argue carefully and charitably, without pretending that every disagreement is a rejection of Jesus.

The same historical honesty should govern how Christians speak to skeptics. We do not need to claim that Paul was quoting from a completed copy of Luke when the evidence cannot establish it. We do not need that claim. The evidence we actually possess is already significant: in one of Christianity’s earliest undisputed documents, Gospel tradition is present, authoritative, recognizable, and bounded.

Paul knew when he was handing on the words of the Lord. He also knew when he was not.


The Voice Was Already There

Taken together, these five passages do not prove that Paul was sitting at his desk with completed copies of Matthew, Mark, or Luke opened in front of him. That claim would go beyond the evidence. What they establish is both more modest and more difficult to dismiss: by the time Paul wrote 1 Corinthians, Christians already possessed a body of remembered tradition concerning what Jesus had said and done.

Paul appeals to Jesus’ teaching about divorce. He knows a command concerning the support of those who proclaim the Gospel. He passes on an account of Jesus breaking bread and interpreting the cup on the night of his betrayal. Just as importantly, Paul recognizes when that inherited tradition does not contain a direct answer to the question he is facing.

That is not how someone treats a voice he believes he is free to invent. It is how someone treats a source he believes he has received.

A skeptic may reasonably argue that oral traditions can develop, that memories can be shaped in transmission, or that these parallels do not prove every scene in the later Gospels happened exactly as narrated. Those questions deserve serious consideration. But they do not erase the historical evidence before us. The teachings and actions of Jesus did not suddenly appear when the evangelists completed their books. They were already being remembered, repeated, taught, and used to govern Christian communities across the Mediterranean world.

This also changes how we should think about Paul. He was not constructing Christianity on an empty foundation or replacing the historical Jesus with a religion of his own imagination. Paul inherited a movement that already had a Lord, a message, a sacred meal, ethical teachings, and traditions about the final night of Jesus’ life. He carried that message into new territory, but he did not pretend to be its beginning.

For Christians, this means there is no reason to fear an honest discussion about when the Gospels reached their final written form. The faith did not wait for the last Gospel manuscript to exist. The message was already moving through the churches, carried by witnesses, teachers, missionaries, shared practices, and remembered words.

For skeptics, it means the history cannot be reduced to the claim that anonymous writers invented a speaking Jesus several generations after his death. Before the completed Gospels gave us their sustained narratives, Paul was already distinguishing between what Jesus had taught, what the churches had received, and what Paul himself was now advising.

When the written Gospels finally brought the story together, they were not introducing the Christian world to a Jesus whose voice had never been heard before. They were giving lasting narrative form to a voice Christians were already quoting, obeying, and carefully refusing to imitate when no remembered command was known.

The Gospel books would preserve that voice in writing. First Corinthians shows us that the voice was already there.

The Common Ground: Why Christians and Skeptics Should Begin with Paul’s Seven Letters

Imagine a Christian and a skeptic sitting down at the same table to discuss whether Jesus rose from the dead.

The Christian places the Bible on the table and says, “This is the Word of God.”

The skeptic immediately responds, “I do not believe that.”

The discussion has ended before the evidence has even been examined. The Christian is asking the skeptic to accept the authority of an entire collection of writings before considering the central event upon which that authority ultimately depends.

We do not need to begin that way.

The Christian and the skeptic do not have to agree about biblical inspiration, inerrancy, Gospel authorship, church tradition, or the Old Testament before beginning an investigation of the resurrection. There is a smaller collection of documents that almost every serious reconstruction of early Christianity must confront.

These are the seven letters of Paul commonly called “undisputed”:

  • Galatians
  • First Thessalonians
  • First Corinthians
  • Second Corinthians
  • Romans
  • Philippians
  • Philemon

The Christian believes these letters belong within inspired Scripture. The skeptic does not have to accept that conclusion. The skeptic only needs to examine whether these are genuine first-century letters associated with Paul and his missionary communities.

That gives us a place to begin together.

Common ground does not mean that we have reached a common conclusion. It means that we have agreed upon the evidence that any conclusion must explain.


Why These Seven Letters?

The New Testament contains thirteen letters bearing Paul’s name. Some scholars accept all thirteen as substantially Pauline. Others question several of them.

The seven undisputed letters are not necessarily the only letters Paul wrote. They are the letters accepted as authentically Pauline across the broadest range of historical scholarship.

Their approximate dates are:

  • Galatians, approximately A.D. 48
  • First Thessalonians, approximately A.D. 50-51
  • First Corinthians, approximately A.D. 53-55
  • Second Corinthians, approximately A.D. 55-56
  • Romans, approximately A.D. 56-57
  • Philippians, sometime during Paul’s imprisonment, probably in the 50s or early 60s
  • Philemon, also written during an imprisonment, probably in the 50s or early 60s

This series follows an early South Galatian chronology and dates Galatians to approximately A.D. 48. Many scholars place Galatians in the middle of the 50s. That disagreement affects the precise chronology, but not the larger conclusion. Galatians was written during Paul’s active missionary life and within the first generation after the death of Jesus.

Calling these letters “undisputed” does not mean that no one has ever challenged them. Some critics have denied that Paul wrote any of them. It also does not mean that every verse or the present arrangement of every letter is beyond question.

“Undisputed” means that these seven have become the durable critical foundation for reconstructing the historical Paul and the earliest Christian movement.

They are not seven independent witnesses. They come from the same broad Pauline missionary network, and several name co-senders such as Timothy, Silvanus, and Sosthenes. Romans even names Tertius as the person who physically wrote down the letter.

Nevertheless, they provide several different pieces of correspondence addressed to different communities, during different circumstances, over a period of years. Together they allow us to hear Paul’s voice, observe his relationships, follow developing conflicts, and identify traditions that existed before he wrote them down.


These Letters Were Not Protected from Criticism

The seven letters are not important because the church placed them in a glass case where historians were forbidden to touch them. They have spent more than a century and a half under sustained cross-examination.

In 1845, Ferdinand Christian Baur reduced the secure Pauline collection to four letters:

  • Galatians
  • First Corinthians
  • Second Corinthians
  • Romans

Baur called these the four principal letters because he believed they displayed Paul’s personality and historical circumstances so powerfully that their authenticity could not reasonably be denied.

He wrote:

“There has never been the slightest suspicion of inauthenticity cast upon these four letters. They bear the character of Pauline originality so unmistakably that there is no conceivable ground for raising critical doubts about them.”

Ferdinand Christian Baur, Paul, the Apostle of Jesus Christ, vol. 1, pp. 245-246, 1845

Baur was not trying to defend the traditional New Testament. He rejected or questioned most of the letters bearing Paul’s name. He even believed portions of Romans were added later.

Other critics, however, concluded that Baur had cut too deeply. By 1862, Adolf Hilgenfeld explicitly recognized the same seven-letter collection commonly accepted today:

“Besides those four unabridged principal letters, First Thessalonians and the letters to the Philippians and Philemon also have a well-founded claim to recognition as genuine.”

Adolf Hilgenfeld, “The Two Letters to the Thessalonians, According to Their Content and Origin,” Journal for Academic Theology 5, p. 226, 1862

The seven were therefore not created by church authorities trying to protect the Bible. They emerged as critics examined individual letters and concluded that the evidence justified expanding Baur’s four-letter core.

Then the criticism became even more radical.

Bruno Bauer, who should not be confused with Ferdinand Christian Baur, attempted to eliminate every authentic Pauline letter. Later critics known as the Dutch Radicals argued that the letters were second-century literary creations rather than genuine correspondence from Paul.

Willem Christiaan van Manen summarized their conclusion:

“With respect to the canonical Pauline Epistles, the later criticism under consideration has learned to recognise that they are none of them by Paul; neither fourteen, nor thirteen, nor nine or ten, nor seven or eight, nor yet even the four so long ‘universally’ regarded as unassailable.”

Willem Christiaan van Manen, “Paul,” Encyclopaedia Biblica, vol. 3, col. 3627, 1902

The movement of the debate is important.

Church tradition handed scholars thirteen letters bearing Paul’s name. Baur reduced the secure foundation to four. Other critics restored three, producing the seven. Radical critics then tried to reduce the collection to zero.

The attempt to reach zero did not persuade the wider field.

This does not prove the seven authentic by majority vote. It demonstrates that they are not a maximal Christian claim protected from investigation. They are the minimum historical collection that remained after prolonged criticism.


What Have Critics Tried to Explain Away?

The most serious challenges have generally taken four forms.

First, some critics have argued that the letters were created during the second century, perhaps around the time of Marcion.

Second, some have treated them as literary compositions written in Paul’s name rather than real correspondence.

Third, scholars have identified apparent contradictions, abrupt transitions, and possible later additions within the letters.

Fourth, statistical and computer analysis has been used to argue that the writing styles belong to different authors.

Each challenge has contributed something valuable. The letters are more complicated than an older view of Paul sitting alone and writing thirteen finished theological essays might suggest.

But exposing complexity is not the same as disproving authorship.

A successful alternative theory must do more than show that forgery, editing, or later collection was possible. It must explain the surviving evidence better than the conclusion that genuine correspondence from Paul lies behind these letters.

Possibility alone is not an explanation.


The Letters Appear Too Early to Be Second-Century Creations

The claim that Paul’s letters originated in the middle of the second century faces an early piece of evidence from Rome.

First Clement was written from the church of Rome to the church of Corinth. It is commonly dated around A.D. 95, although its exact date remains debated.

The author tells the Corinthians:

“Take up the letter of the blessed apostle Paul. What did he first write to you at the beginning of the gospel? Under the Spirit’s guidance, he wrote to you about himself, Cephas, and Apollos, because even then you had formed factions.”

First Clement 47.1-3, commonly dated c. A.D. 95

The writer is not merely using language that resembles Paul. He explicitly directs the Corinthians to consult an earlier letter from Paul and identifies the controversy recorded in First Corinthians:

“Each of you says, ‘I belong to Paul,’ ‘I belong to Apollos,’ ‘I belong to Cephas,’ or ‘I belong to Christ.’”

First Corinthians 1:12

If the common dating of First Clement is approximately correct, First Corinthians already existed near the end of the first century. It was associated with Paul, known in Rome, and expected to remain available in Corinth.

During the early second century, Polycarp wrote to Christians in Philippi:

“Neither I nor anyone like me can match the wisdom of the blessed and glorious Paul. When he was among you, in the presence of the people then living, he accurately and firmly taught the word of truth. When he was absent, he wrote letters to you. If you study them carefully, you will be able to build yourselves up in the faith given to you.”

Polycarp, Letter to the Philippians 3.2, early second century

Polycarp remembers Paul as a real teacher who had been physically present in Philippi. He also knows written communications associated with Paul. His use of the plural “letters” may indicate that more than one communication eventually contributed to the Philippian material we possess.

By approximately A.D. 140, Marcion possessed a collection of ten Pauline letters. That collection included all seven letters now considered undisputed.

Marcion’s collection has not survived, so it must be reconstructed from later writers who opposed him. While discussing Philemon, Tertullian wrote:

“Only this letter benefited from being so short: it escaped Marcion’s tampering. Yet since he accepted a letter written to one individual, I wonder why he rejected the two written to Timothy and the one to Titus concerning church order.”

Tertullian, Against Marcion 5.21.1, c. A.D. 207

Tertullian’s accusation that Marcion altered the letters is polemical and should not be treated as neutral history. His testimony nevertheless shows that Marcion’s collection included even the tiny and personal Letter to Philemon.

A substantial collection of recognizable Pauline letters therefore existed by approximately A.D. 140, and individual letters are attested earlier.

A theory placing their creation shortly before Marcion must explain how the letters were produced, collected, edited into different textual forms, distributed across widely separated communities, and accepted by opposing Christian movements within a very short period.

That is not impossible. It is simply less economical than the conclusion that genuine earlier correspondence had already been collected.


The Letters Fit the World of the First Christian Generation

The seven letters consistently inhabit the disputes of the middle of the first century.

Paul argues about circumcision, Jewish and Gentile table fellowship, the law of Moses, participation in Israel’s promises, and the collection of money for poor believers in Jerusalem. He knows leaders called Cephas, James, and John. Jerusalem remains an active center of the movement.

Paul writes:

“After three years, I went up to Jerusalem to become acquainted with Cephas and stayed with him for fifteen days. I saw none of the other apostles except James, the Lord’s brother.”

Galatians 1:18-19

The letters do not pause to introduce Cephas or James. Paul assumes that his readers understand why these people matter.

They also do not naturally address the controversies that became prominent during the middle of the second century. Paul does not discuss developed Gnostic systems, the aftermath of the Bar Kokhba revolt, or the increasingly formal debates over bishops and church offices.

Silence alone cannot prove a date. A later writer could create a story set in an earlier period. But the seven letters repeatedly fit the first-century Jewish and Gentile missionary world without needing to explain that world to their readers.

A second-century origin must therefore do more than suggest that a talented author could imitate the past. It must identify why that author constructed such an extensive network of first-generation disputes while showing comparatively little interest in the controversies of the period in which he was supposedly writing.


The Letters Behave Like Unfinished Correspondence

The seven letters are not smooth biographies of Paul or carefully ordered summaries of Christian doctrine.

They are filled with changing plans, forgotten details, unanswered questions, financial arrangements, personal disagreements, illnesses, requests, accusations, and attempts at reconciliation.

In First Corinthians, Paul begins thanking God that he baptized very few people in Corinth. Then he remembers another household and corrects himself:

“I thank God that I baptized none of you except Crispus and Gaius, so no one can say that you were baptized in my name. I also baptized the household of Stephanas. Beyond that, I do not remember whether I baptized anyone else.”

First Corinthians 1:14-16

The correction does not advance Paul’s argument. It interrupts it. Paul appears to remember another baptism while dictating and adds it before continuing.

Second Corinthians contains defenses of travel plans Paul changed. Philippians discusses the illness and return of Epaphroditus. Philemon asks for a guest room to be prepared because Paul hopes to visit. Romans sends greetings to a long list of named people.

A literary author could invent such details. Fiction has always contained realistic names and circumstances. But the more incidental details a forgery contains, the more historical relationships the theory must invent and coordinate.

The undisputed letters contain not one isolated personal touch but an entire social world extending across Corinth, Galatia, Macedonia, Jerusalem, Ephesus, and Rome.

A later literary theory must explain that world at least as well as the straightforward conclusion that the letters arose from real relationships.


Complicated Transmission Does Not Eliminate Paul

The seven letters did not necessarily reach us in precisely the form in which they first left Paul’s hands.

First Corinthians refers to an earlier letter that has not survived:

“I wrote to you in my letter not to associate with sexually immoral people.”

First Corinthians 5:9

Second Corinthians refers to another painful letter:

“I wrote to you out of great distress and anguish of heart, with many tears, not to cause you pain, but to let you know the abundant love I have for you.”

Second Corinthians 2:4

These references show that the New Testament preserves only part of Paul’s correspondence with Corinth. Some scholars believe Second Corinthians may combine portions of several authentic Pauline letters. Similar questions have been raised about Philippians and the ending of Romans.

Scholars also debate whether particular passages were added later. First Corinthians 14:34-35 and First Thessalonians 2:13-16 are among the most frequently discussed examples.

These questions matter, but they are questions about transmission and literary unity. They do not automatically prove that an anonymous second-century writer created the entire Pauline world.

If several genuine letters were later joined together, Paul has not disappeared. We may actually possess more fragments of his correspondence than the present number of canonical titles suggests.

A Christian does not need to fear this distinction. The resurrection evidence in First Corinthians 15 and Paul’s relationships with Cephas and James in Galatians do not depend upon every disputed passage being original or every canonical letter being a single untouched document.


Computer Analysis Did Not Produce a Replacement

During the 1960s, computer analysis was used to count Greek words, sentence lengths, and grammatical patterns within Paul’s letters. One famous study concluded that Paul wrote only five letters.

Later statistical studies produced substantially different results. One found no compelling stylistic reason to reject twelve of the thirteen letters bearing Paul’s name.

The problem is not that computers cannot recognize patterns. The problem is that the result changes according to which patterns are measured and which letters are assumed to be genuine at the beginning.

We possess no independently verified sample of Paul’s writing outside the collection. Paul also addressed different subjects, used co-senders, dictated to secretaries, and wrote over a period of years.

Computer analysis has helped scholars identify similarities and differences. It has not supplied an agreed mathematical solution that displaces the seven-letter foundation.


Why Scholarly Agreement Matters, and Why It Is Not Enough

Historical truth is not established by counting votes.

A letter would not become authentic merely because every professor in the world agreed about it. Scholars can inherit assumptions, follow trends, and make mistakes.

Nevertheless, a broad and durable consensus tells us where responsible investigation should begin, especially when that consensus includes scholars with sharply different religious commitments.

Bart Ehrman summarizes the present situation:

“Just about every, not quite every, New Testament scholar on the planet agrees that Paul wrote these seven.”

Bart D. Ehrman, “Pauline Forgeries: 2 Thessalonians as a Test Case,” 2014

The important words are “not quite every.” Exceptions remain, and their arguments should be heard.

But a skeptic cannot dismiss these documents merely by observing that ancient forgery existed or that later editing was possible. The skeptical explanation must account for the evidence at least as well as Pauline authorship does.

The seven are not called undisputed because they escaped criticism. They are called undisputed because, after more than 160 years of direct challenges, they remain the common working foundation.


What the Skeptic Should Concede

Accepting these letters as authentic does not require the skeptic to believe that Paul was inspired.

It does not require believing that Paul was always correct, that every experience he interpreted as divine actually came from God, or that Jesus rose from the dead.

It requires something more limited.

By the middle of the first century, there was a real missionary named Paul writing to real communities. Those communities already worshiped Jesus as Lord, practiced baptism and the Lord’s Supper, claimed experiences of the Holy Spirit, and proclaimed that God had raised Jesus from the dead.

Paul did not invent resurrection belief years later. He tells us that he had once opposed and persecuted the movement before joining it. He says he received an existing resurrection proclamation and later spent time with Cephas and James.

The skeptic may conclude that Paul and the earlier witnesses were mistaken about what they experienced. That explanation remains available.

What is no longer available is the casual claim that the resurrection arose as a legend generations later, after the original participants were gone. The seven letters place resurrection belief, named appearance traditions, and Paul’s contact with the Jerusalem leaders inside the earliest surviving Christian evidence.

The skeptic still has room to disagree. But the skeptic now has something definite to explain.


What the Christian Gains

The Christian does not need to prove everything before believing anything.

We do not need to settle the authorship of every Gospel, defend all thirteen letters attributed to Paul, solve every biblical contradiction, or establish a theory of inerrancy before examining the resurrection.

We can begin with the seven letters accepted across the widest range of scholarship.

Even if someone insisted upon retreating from seven letters to Baur’s original four, the heart of our resurrection evidence would remain untouched.

Galatians would remain. First Corinthians would remain.

Paul’s visit with Cephas and James would remain:

“I went up to Jerusalem to become acquainted with Cephas and stayed with him for fifteen days. I saw none of the other apostles except James, the Lord’s brother.”

Galatians 1:18-19

The resurrection tradition would remain:

“I delivered to you as of first importance what I also received: that Christ died for our sins according to the Scriptures, that he was buried, that he was raised on the third day according to the Scriptures, and that he appeared to Cephas, then to the Twelve.”

First Corinthians 15:3-5

Our investigation is not balanced upon the most disputed edge of the New Testament. It begins within the hardest documentary center.

That does not remove every mystery or answer every objection. It gives the Christian somewhere solid to stand while asking the questions.


Conclusion: The Evidence We Must Explain

The seven letters are not the verdict. They are the evidence admitted for examination.

They do not prove by themselves that Jesus rose from the dead. They establish that the resurrection proclamation arose early, that Paul received it rather than invented it, and that he personally entered the network of people named within that proclamation.

The Christian and the skeptic can therefore place these seven documents on the same table.

The Christian sees them as Scripture. The skeptic may see them only as historical correspondence. Either way, both must reckon with what they contain.

The next question is not yet whether the witnesses were right.

Before we evaluate their testimony, we should ask what kind of faith already existed inside these earliest documents.

If every Gospel, every disputed letter, and every later Christian writing disappeared, how much Christianity would remain within Paul’s seven undisputed letters?

More than many Christians or skeptics realize.
