The assassination of Commodus on December 31, AD 192 plunged Rome into civil war. In what became known as the Year of the Five Emperors (AD 193), power passed rapidly between Pertinax, Didius Julianus, Pescennius Niger, and Clodius Albinus. Finally, Septimius Severus—an African-born general from Leptis Magna—emerged victorious. He would rule for nearly two decades (193–211).

For Christians, nothing new is recorded under these brief emperors—only the continued, by now ancient, tradition that those accused of the name and refusing to deny it could be put to death. This tradition reached back to Nero’s precedent, when Christians were first condemned in Rome.

Once Severus consolidated power, however, a new wave of persecution broke out. By his tenth year (AD 202/203), we find evidence across Africa and Egypt of Christians martyred, catechumens executed, and great teachers forced to reckon with Rome’s hostility. And although only one late source names it directly, the tradition survives that Severus had issued a law forbidding conversions to Judaism and Christianity.

The Edict, Plainly Stated

Historia Augusta, Life of Severus 17.1 (Loeb):

“He forbade anyone to become a Jew, and he enacted severe penalties against those who attempted to convert to Judaism and Christianity.”

This is our sole explicit witness to the edict. The Historia Augusta was written in the 4th century and is often unreliable. But the law it describes explains why, at precisely this time, catechumens and teachers were executed from Carthage to Alexandria.

Eusebius: A Wave of Persecution

Eusebius, Church History 6.1.1–2 (Loeb):

“When Severus had been emperor for ten years, he stirred up persecution against the churches, and illustrious testimonies of martyrdom were given at that time. At Alexandria the great teachers of the faith were most distinguished, and in other regions also a great many received crowns of martyrdom with all kinds of tortures and punishments. At that time Origen, a young man, devoted himself with all earnestness to the divine word, while his father Leonidas received the crown of martyrdom.”

Here Carthage and Alexandria are linked. In North Africa, women and slaves were led to the arena. In Egypt, a father was executed, leaving his son to become the greatest theologian of early Christianity.

The Martyrs of Carthage: Perpetua, Felicitas, and Saturus (North Africa, AD 203)

The most vivid testimony of Severus’ persecution comes from the Passion of Perpetua and Felicitas. Its uniqueness lies in the fact that it is partly autobiographical—the first-person diary of Perpetua herself, later woven together with Saturus’ vision and an eyewitness account of their deaths.

When her father begged her to deny Christ, Perpetua answered with a simplicity Rome could not overcome:

“Father, do you see this little pitcher? Can it be called by any other name than what it is? … So too I cannot call myself anything else than what I am, a Christian.” (Passion 3–4)

She was imprisoned with several other catechumens. Among them was Saturus, a Christian teacher who had not been arrested at first but chose to surrender himself so he could share their chains. His voluntary imprisonment made him a model of pastoral courage, and in Perpetua’s visions he appears as her guide.

At first, Perpetua struggled with the darkness and the crowding of prison, but her greatest fear was for her baby:

“I was horrified, for I had never experienced such darkness. Oh, terrible day! The crowding of the mob, the harsh treatment by the soldiers, the extortion of the jailers. Then I was distressed by anxiety for my baby.” (Passion 3–5)

Eventually she was allowed to nurse her son in prison:

“Then I was allowed to nurse him in prison, and I recovered my strength, and my prison became to me a palace, so that I would rather have been there than anywhere else.” (Passion 5)

Later the baby was given into the care of her family. Though she grieved, she found freedom to face martyrdom without distraction:

“I endured great pain because I saw my infant wasted with hunger … Then I arranged for the child to stay with my mother and brother. For a little while I took care of the child in prison, but later I gave him up. And immediately the prison became a place of refreshment to me, and my anxiety for the child no longer consumed me.” (Passion 6)

That is the last we hear of her son, who survived, raised by his grandmother. The absence of any mention of her husband is striking. Whether she was widowed or separated we do not know; the editor of the Passion was not interested in her social status, but in her confession of Christ.

Perpetua’s visions gave her courage. She saw a narrow bronze ladder stretching to heaven, lined with swords and hooks, with a dragon lurking at its base. Saturus climbed first, and she followed, treading on the dragon’s head and entering a garden where a shepherd gave her milk turned into a cake, and all around said “Amen” (Passion 4).

Her fellow prisoner Felicitas faced her own trial. She was a slave woman, eight months pregnant when arrested. Roman law forbade executing pregnant women, and she feared she might be separated from her companions. She prayed to give birth before the day of the games, and her prayers were answered. When mocked by a jailer for her cries in labor, she replied:

“Now I myself suffer what I suffer, but then another will be in me who will suffer for me, because I am to suffer for him.” (Passion 15)

At last came the day of execution:

“The day of their victory dawned, and they marched from the prison into the amphitheater, as if into heaven, with cheerful looks and graceful bearing. Perpetua followed with shining step as the true spouse of Christ. When the young gladiator trembled to strike her, she guided his hand to her throat, for it was as if such a woman could not be slain unless she herself were willing.” (Passion 18, 21)

Rome called it punishment; the Christians called it victory. The amphitheater was meant to shame them before the crowd, but Perpetua, Felicitas, and Saturus walked into it as though into heaven.

Tertullian of Carthage (North Africa, c. 197–220)

Before the main outbreak of persecution under Severus, another Carthaginian gave voice to the church in Latin: Tertullian. A lawyer by training and a fiery Christian apologist, he addressed his works to Roman officials, governors, and pagan audiences who misunderstood the church. His writings prove that Christians in Africa were already living under suspicion and facing punishment years before Severus’ edict of 202/203.

In his Apology (c. AD 197), addressed to the provincial governors and magistrates of North Africa, Tertullian insists that Christians are everywhere:

Apology 37 (Loeb):

“We are but of yesterday, and we have filled every place among you—cities, islands, fortresses, towns, marketplaces, the very camp, tribes, companies, palace, senate, forum; we have left nothing to you but the temples of your gods.”

Persecution was already a reality. Christians were blamed for every disaster:

Ad Nationes 1.7:

“If the Tiber rises as high as the city walls, if the Nile does not rise into the fields, if the heavens give no rain, if the earth quakes, if there is a famine or a plague, the cry at once is, ‘The Christians to the lion!’”

And yet, persecution only multiplied them:

Apology 50:

“We multiply whenever we are mown down by you: the blood of Christians is seed.”

Later, in To Scapula (written around AD 212 to Scapula, the proconsul of Africa), he warned Rome’s governor directly:

To Scapula 5 (Loeb):

“Kill us, torture us, condemn us, grind us to dust; your injustice is the proof that we are innocent. … The more often you mow us down, the more we grow; the blood of Christians is seed.”

Tertullian’s writings show that persecution was not sudden but constant. By the time Severus issued his edict, the soil had already been watered with blood—and, as Tertullian argued, that blood was the seed of growth.

Clement of Alexandria (Egypt, c. 190–203+)

Meanwhile in Alexandria, the church had established a tradition of Christian teaching known as the catechetical school. Its master was Clement of Alexandria, a philosopher-turned-Christian who wrote in Greek to the city’s educated elite.

Clement’s trilogy of major works shows the breadth of his teaching:

Protrepticus (Exhortation to the Greeks):

“Leave the old delusion, flee from the ancient plague; seek after the new song, the new Logos, who has appeared among us from heaven. He alone is both God and man, the source of all our good.” (Protrepticus 1.5)

Paedagogus (The Instructor):

“The Word is all things to the child: father and mother, tutor and nurse. ‘Eat my flesh,’ He says, ‘and drink my blood.’ Such is suitable food for children, the Lord Himself made nourishment, love, and instruction.” (Paedagogus 1.6)

Stromata (Miscellanies):

“The true gnostic is one who imitates God as far as possible: he rests on faith, is founded on love, is educated by hope, and is perfected by knowledge. He has already attained the likeness of God, being righteous and holy with wisdom.” (Stromata 7.10)

On martyrdom, he wrote plainly:

“Many martyrs are daily burned, confined, or beheaded before our eyes, so that not only in ancient times but also among ourselves may one see such examples, being set forth in their thousands.” (Stromata 4.4)

And on wealth and charity:

Who Is the Rich Man That Shall Be Saved? 27:

“Wealth is not to be thrown away. It is a material for virtue, if it be rightly used. Riches are called good if they are distributed well; for they can become instruments of righteousness. Let the rich man do good, let him give liberally, let him share willingly, and he will be perfect.”

For Clement, charity was not about ascetic rejection but about transformed stewardship. Wealth was a tool, not a curse—its danger was in clinging to it selfishly, its virtue in giving it freely. He presented charity as a spiritual discipline: rational, cheerful, and loving generosity for the good of others.

When Severus’ persecution reached Alexandria around AD 202, Clement fled the city and took refuge in Cappadocia, never to return. Leadership of the Alexandrian school passed to the teenage Origen. But Clement’s writings remained a legacy: in the empire’s intellectual capital, he had given Christianity an intellectual defense, a moral handbook, and a vision of charity rooted not in fear but in love.

Origen and Leonidas (Alexandria, Egypt, AD 202/203)

When Leonidas, Origen’s father, was executed, Origen was only about seventeen years old. He was the eldest of seven children, and his family’s property was confiscated. He suddenly found himself destitute, responsible for his widowed mother and six younger siblings.

Eusebius, Church History 6.2.2–3 (Loeb):

“Leonidas, the father of Origen, was beheaded. Origen was eager to accompany him and to die as a martyr, but his mother prevented him by hiding all his clothes and thus compelled him to remain in the house. And he wrote to his father in prison, saying: ‘Take heed not to change your mind on our account.’”

Eusebius, Church History 6.3.9–11 (Loeb):

“Leonidas would often, when Origen was sleeping, uncover his breast and reverently kiss it, as though it were already sanctified by the divine Spirit within him. He educated his boy not only in general studies but above all in the Holy Scriptures.”

To support his family, Origen opened a school of grammar and literature, teaching pagans by day and catechumens by night. He lived with radical austerity, sleeping on the ground and fasting, so he could provide for his mother and siblings. In time, wealthy patrons like Ambrose of Alexandria also supported him, funding secretaries to copy his works.

When Clement fled, Origen inherited the catechetical school. This “school” (didaskaleion) was not simply a building but a tradition of Christian teaching in Alexandria, begun by Pantaenus, a Stoic philosopher turned Christian. Now, still in his teens, Origen became its master. From there he wrote commentaries on nearly every book of the Bible, debated pagan philosophers, and composed On First Principles, the first systematic theology in Christian history.

The persecution that took his father’s life launched his own.

Hippolytus of Rome (Italy, c. 200–215)

In Rome, the church was codifying its order even under threat. Hippolytus, writing in Greek, preserved the earliest liturgy and church order that has survived.

Apostolic Tradition (On Ordination, ch. 3):

“Let the bishop be ordained after he has been chosen by all the people. … Let all lay hands on him and pray, saying: ‘O God, pour forth the power of your Spirit upon this your servant, whom you have chosen to be shepherd of your people.’”

Apostolic Tradition (On Baptism, ch. 21):

“Do you believe in God the Father Almighty? … Do you believe in Christ Jesus, the Son of God, who was born … crucified … and rose again … and will come to judge the living and the dead? … Do you believe in the Holy Spirit, and the holy Church, and the resurrection of the flesh? … And so he is baptized a third time.”

Apostolic Tradition (On the Eucharist, ch. 4):

“We give you thanks, O God, through your beloved Son Jesus Christ, whom you sent to us as Savior and Redeemer … and when he had given thanks, he said: ‘This is my body, which is for you.’ … Remembering therefore his death and resurrection, we offer to you this bread and this cup, giving thanks to you.”

From the same hand we also have the Refutation of All Heresies, in which he exposed pagan astrology and Gnostic sects:

Refutation 4.37:

“If everything is under the control of fate, then let no one be blamed for sins, nor praised for virtues. But if this is absurd, then their teaching is false. For man has been made free by God.”

Refutation 9.7:

“There are those who, under the name of Christ, corrupt the truth by their deceit. But we have the tradition from the apostles, delivered through the succession of bishops, and we guard it in the Church by the Holy Spirit.”

Hippolytus shows us that in Rome itself—at the empire’s heart—Christians were not retreating underground but continuing to baptize, ordain, and celebrate the Eucharist. At the very time Severus forbade conversions, Rome’s church was still welcoming new converts and defending its doctrine.

Minucius Felix (Rome or North Africa, c. 197–210)

Octavius is the earliest surviving Christian apology written in elegant Latin. It is framed as a dialogue between Caecilius, a pagan, and Octavius, a Christian, with Minucius himself as arbiter.

On slanders against Christians, Caecilius charges:

Octavius 9:

“It is said that in your sacred rites you slay an infant and drink its blood, and that after the banquet you join in incestuous unions in shameless darkness. These are the fables you believe of us—things which you would not even believe of your own enemies.”

Octavius replies with a portrait of Christian life:

Octavius 31–32:

“They love one another before they know one another; they call one another brother and sister, and with reason. They are ready even to die for one another. … We neither keep our religion hidden, for our life is made known by its teachings, nor are we silent, since we are always being accused.”

On worship:

Octavius 33:

“We do not worship the images you make, for we know they are made of stone and wood. … Our sacrifice is a pure prayer proceeding from a pure heart.”

On persecution:

Octavius 35:

“Do you think that we are to be pitied, who are counted as your enemies? When we are slain, we conquer; when we are struck down, we are crowned; when we are condemned, we are acquitted.”

Minucius shows us Christianity in Rome’s own idiom: clear, concise, legal Latin rhetoric. He captures both the accusations Christians faced in Severus’ time and the moral beauty of their reply—love, openness, prayer, courage.

Bardaisan of Edessa (Syria/Mesopotamia, c. 200–222)

Far from Rome and Carthage, in the eastern frontier city of Edessa, the philosopher Bardaisan defended Christianity in Syriac against astrology and fatalism. His Book of the Laws of Countries, preserved by his disciples, is a dialogue on fate, free will, and culture.

On free will:

Laws of Countries 617 (Wright trans.):

“The constellations do not compel a man either to be righteous or to be a sinner, nor does fate constrain him to be rich or poor. But every man, according to his own will, approaches what is right, and departs from what is evil.”

On cultural diversity:

Laws of Countries 619:

“The same stars shine everywhere, yet laws differ among the Parthians, the Romans, and the Syrians. If fate compelled, all would live the same way. But men live according to their laws, and these laws are the fruit of free will.”

On the universality of Christianity:

Laws of Countries 622:

“The new law of our Lord is not written on stone but on the heart. Because of it, men from every nation have renounced their former customs and are ready to suffer and even to die rather than transgress it.”

On martyrdom:

Laws of Countries 623:

“This law has not only been written and spoken, but it is practiced. For in all places and in every land, men and women, young and old, endure persecution for the sake of this law, and they do not deny it.”

Bardaisan’s “law” is not Roman statute or Jewish Torah, but the gospel of Christ written on the heart. He stresses that this law is already global: Romans, Syrians, Parthians alike live by it, and all are ready to suffer for it. From the eastern frontier of the empire, Bardaisan shows us Christianity as a universal faith that conquers fatalism with freedom, and unites nations in one confession.

Conclusion

The reign of Septimius Severus (AD 193–211) was decisive for Christianity.

• The edict: remembered in the Historia Augusta, forbidding conversion.
• The martyrs: Perpetua, Felicitas, and Saturus in Carthage; Leonidas in Alexandria.
• The writers:
  • Tertullian (Carthage) — lawyer turned apologist, addressing governors and magistrates, insisting that persecution was constant and blood was seed.
  • Clement (Alexandria) — philosopher turned teacher, whose writings shaped Christian virtue, charity, and knowledge before he fled persecution.
  • Origen (Alexandria) — teenage prodigy, shaped by his father’s death, who built the greatest Christian school of the ancient world.
  • Hippolytus (Rome) — presbyter preserving baptismal, eucharistic, and ordination rites, proving the church’s order survived in the capital.
  • Minucius Felix (Rome/Africa) — polished Latin lawyer refuting slander and showing Christian innocence and love.
  • Bardaisan (Edessa) — philosopher on the frontier, proclaiming the gospel as the new law written on the heart, freely obeyed in every nation.

By Severus’ reign, Christian voices were speaking from every corner of the empire. Rome tried to choke Christianity at its source—conversion—but instead gave the church martyrs, apologists, and theologians whose words and courage still inspire today.
