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.
