Christians kneel in prayer around an old man on the sand of a Roman arena as a lion climbs out of a pit, with bodies on burning stakes along the arena's edge.

The Martyrs' Church

The church under Roman law, from Pliny's letter to Trajan to the edict of Galerius and the letter of Constantine and Licinius.

Span
AD 100 to 313
Boundary
Galerius's edict and the letter that followed it bring the span to a close.
Label
Christianity under persecution, applied by Philip Schaff, History of the Christian Church, volume 1

For two hundred years a Roman governor could put a Christian to death for the name alone.

Revelation 2:10 BSB
Do not fear what you are about to suffer. Look, the devil is about to throw some of you into prison to test you, and you will suffer tribulation for ten days. Be faithful even unto death, and I will give you the crown of life.

Summary

A Christian was tried when someone brought a charge and a governor heard it. Twice an emperor told every province to sacrifice, first Decius and then Diocletian. Between those years the church met, wrote and chose its bishops in long spells of peace. It kept its own record of the trials, and at the end it got its buildings back.

  • The record is the church's letters and trial reports, the emperors' edicts and papyrus certificates.
  • Its witnesses wrote from Smyrna, Lyons, Carthage, Rome, Alexandria and Caesarea.
  • The worst quarrel was over believers who denied Christ and then asked to come back.

The Era's Own Voice: Polycarp Before the Proconsul

The Martyrdom of Polycarp, chapter 10, in the English of Roberts and Donaldson.

The church of Smyrna wrote to another church to tell how its old bishop died. Pressed to swear by the fortune of Caesar, Polycarp declared that he was a Christian. His answer to the proconsul shows the honour a Christian still owed to Rome.

“But Polycarp said, ‘To thee I have thought it right to offer an account [of my faith]; for we are taught to give all due honour (which entails no injury upon ourselves) to the powers and authorities which are ordained of God. But as for …”

The letter names the proconsul Statius Quadratus and gives a day and an hour, but no year.

The Five Turning Points

A letter, a papyrus, a bishop's letter and two histories hold them.

The law changed five times, from Trajan's rule to its repeal.

The five, with the record a reader can open for each.

The Story From Pliny to Milan

The trials in order, from the church's own records and the emperors' edicts.

About AD 111 to 112 Pliny, governor of Bithynia, wrote to Trajan about the Christians brought before him. He asked each whether he was a Christian, asked twice more under threat, and had those who held to it executed. Trajan replied that Christians were not to be hunted and that unsigned accusations were not to be heard.

But if you suffer as a Christian, do not be ashamed, but glorify God that you bear that name.

Peter names the charge these courts tried, which was the name itself.

1 Peter 4:16BSB

Ignatius, bishop of Antioch, was taken under guard to Rome to die. He wrote ahead to the church there, "I am the wheat of God, and let me be ground by the teeth of the wild beasts."

At Rome Justin, who had written defences of the faith, stood with his companions before the prefect Rusticus, who took office in 163. Rusticus sentenced those who refused to sacrifice to be scourged and beheaded.

I know where you live, where the throne of Satan sits. Yet you have held fast to My name and have not denied your faith in Me, even in the day when My faithful witness Antipas was killed among you, where Satan dwells.

It shows a martyr in a church of Asia a generation before Polycarp.

Revelation 2:13BSB

In Gaul about 177 the churches of Lyons and Vienne suffered, and their letter survives in Eusebius. Their bishop Pothinus was more than ninety. Blandina was tortured from morning till evening until her torturers owned themselves beaten.

At Carthage on 17 July 180 the proconsul asked Speratus of Scilli what was in his chest. He answered, "Books and epistles of Paul, a just man."

They have conquered him by the blood of the Lamb and by the word of their testimony. And they did not love their lives so as to shy away from death.

John's vision joins the testimony and the death, as these letters did.

Revelation 12:11BSB

In 203 Perpetua was held at Carthage with her infant son. Her prison diary survives inside the Passion of Perpetua and Felicity. When her father begged her to give way, she pointed to a pitcher and said she could no more call herself anything else than call it by another name.

Felicity was eight months pregnant at her arrest and gave birth in prison before the games.

Therefore everyone who confesses Me before men, I will also confess him before My Father in heaven.

Jesus' promise to those who confess Him is what Perpetua chose over her father's plea.

Matthew 10:32BSB

In 250 Decius ordered sacrifice. Fabian, bishop of Rome, died, and Origen was put in the iron collar and the stocks. Officials signed certificates for those who sacrificed, and over forty survive from Egypt. One reads, "We have always sacrificed to the gods."

Many gave way at once. Cyprian, bishop of Carthage, wrote that some ran "to the market-place of their own accord."

But whoever denies Me before men, I will also deny him before My Father in heaven.

This warning was the text the strict quoted against receiving the lapsed back.

Matthew 10:33BSB

When the danger passed, the lapsed asked to come back. Cyprian received them after penance, case by case, and held that taking a certificate was a lesser fall than offering the sacrifice. In 251 Novatian was set up at Rome against the new bishop Cornelius, holding that the church could not receive them.

Cornelius counted in his church forty-six presbyters and over fifteen hundred widows and persons in distress.

Jesus asked a third time, “Simon son of John, do you love Me?” Peter was deeply hurt that Jesus had asked him a third time, “Do you love Me?” “Lord, You know all things,” he replied. “You know I love You.” Jesus said to him, “Feed My sheep.

Peter's restoring after his denial was the text for receiving those who had fallen.

John 21:17BSB

Valerian struck at the leaders. Cyprian reported his order that bishops, presbyters and deacons be punished, and that Xistus of Rome died in a cemetery with four deacons. Cyprian's own martyrdom followed.

Gallienus then wrote to Dionysius and the other bishops, giving back their places of worship. The next general order came under Diocletian.

And when the Lamb opened the fifth seal, I saw under the altar the souls of those who had been slain for the word of God and for the testimony they had upheld.

John's vision answers the question these deaths raised, where the slain now are.

Revelation 6:9BSB

On 23 February 303 officials forced the doors of the church at Nicomedia and razed it. The next day Diocletian's edict stripped Christians of all honours and dignities, and a later order commanded all the people to sacrifice.

In Palestine, Eusebius records, the martyrdoms ran eight complete years.

Do not be afraid of those who kill the body but cannot kill the soul. Instead, fear the One who can destroy both soul and body in hell.

It names the choice Diocletian's edicts put to every believer.

Matthew 10:28BSB

On 30 April 311 Galerius issued an edict. It allowed Christians "again to be Christians" and asked them to pray for the emperors.

Two years later, on 13 June, Licinius posted the letter he and Constantine had agreed at Milan. It ordered the churches' places returned "without money demanded or price claimed."

Treat everyone with high regard: Love the brotherhood of believers, fear God, honor the king.

Peter told believers to honour the king, and they prayed for the emperors who had tried them.

1 Peter 2:17BSB

Revelation 12:11, Matthew 10:32, Matthew 10:33, John 21:17, Revelation 6:9, Matthew 10:28, 1 Peter 2:17

Why These Years

The label and the first line are Schaff's.

Schaff's History calls its second period "Christianity under persecution in the Roman empire" and runs it from the death of John to the year of Galerius's edict. The span here ends two years later, at the letter that gave back the churches' property.

The Question at Every Trial

Courts in Bithynia and Carthage asked the same thing.

At Carthage in 180 Vestia and Speratus each answered the proconsul, "I am a Christian." Pliny's court in Bithynia had asked the same question about seventy years before.

  1. The apostles left the Sanhedrin, rejoicing that they had been counted worthy of suffering disgrace for the Name.

    It is the first time Acts shows believers suffering for the Name before a court.

    Acts 5:41BSB

The Hard Part: How Many Died

The witnesses run from Origen to Gibbon and Schaff.

Eusebius, Lactantius and the martyrs' own letters give no total of the dead. The letter from Lyons gives none; the figure of 48 dead there comes from a much later martyrology. Origen, writing in the reign of Philip, said the martyrs were few, individuals "who can be easily numbered."

In 1776 Edward Gibbon took Eusebius's ninety-two martyrs of Palestine, counted Palestine one sixteenth of the East, and added the West. He reached "somewhat less than two thousand" executions in the Great Persecution. Schaff answered that the Palestinian list was "a select list" and that "Dodwell and Gibbon have certainly underrated it," as later legend erred the other way. The number is not known.

Beyond the Trials

Two subjects of these years stand on other pages.

The arguments inside the church in these years, over the Gnostics, Marcion and Montanus, belong to the era of the fathers and the creeds. The Bible's own teaching on persecution has its page.

What the Era Handed On

Three things passed to the next church.

It handed on the martyrs' own records, from Polycarp's letter to the court report of the Scillitans and Perpetua's diary.

It handed on an unfinished quarrel. Optatus, writing against the Donatists, named the bishops who had given up the Scriptures.

It handed on its historian. Eusebius studied under Pamphilus, a presbyter of Caesarea who died in the persecution, and called him "my dearest friend."

How the Era Has Been Taught

Writers from the second century to the fourth, each with what he taught about Rome and the persecuted.

Justin Martyr (died 165)
The First Apology, Chapter XVII

How this text has been taught

“And everywhere we, more readily than all men, endeavour to pay to those appointed by you the taxes both ordinary and extraordinary, as we have been taught by Him; for at that time some came to Him and asked Him, if one ought to pay tribute to Caesar; and He answered, ‘Tell Me, whose image does the coin bear?’ And they said, ‘Caesar's.’ And again He answered them, ‘Render therefore to Caesar the things that are Caesar's, and to God the things that are God's.’”

on Mark 12:14The Martyrs' Church

About this saying1 paragraph

Before his own trial Justin wrote his First Apology, and in chapter 17 he points to the taxes Christians paid, as Christ taught.

Tertullian (died 220)
The Apology

How this text has been taught

“If equanimity be the contention, you have Lycurgus choosing death by self-starvation, because the Lacons had made some emendation of his laws: the Christian, even when he is condemned, gives thanks. If the comparison be made in regard to trustworthiness, Anaxagoras denied the deposit of his enemies: the Christian is noted for his fidelity even among those who are not of his religion.”

on 1 Thessalonians 5:18The Martyrs' Church

About this saying1 paragraph

Between 198 and 204 Tertullian wrote his Apology. In chapter 2 he protests that the trials turned on a name. In chapter 46 he set the condemned Christian beside the philosophers.

Cyprian (died 258)
Treatise III. On the Lapsed

How this text has been taught

“Moreover, beloved brethren, a new kind of devastation has appeared; and, as if the storm of persecution had raged too little, there has been added to the heap, under the title of mercy, a deceiving mischief and a fair-seeming calamity. Contrary to the vigour of the Gospel, contrary to the law of the Lord and God, by the temerity of some, communion is relaxed to heedless persons,-a vain and false peace, dangerous to those who grant it, and likely to avail nothing to those who receive it.”

on 1 Corinthians 11:27The Martyrs' Church

About this saying1 paragraph

In 251 Cyprian wrote On the Lapsed, and in chapter 15 he warns against receiving the fallen too easily.

Lucius Caecilius Firmianus Lactantius (died 325)
Of the Manner in Which the Persecutors Died (Chapter LII)

How this text has been taught

“I relate all those things on the authority of well-informed persons; and I thought it proper to commit them to writing exactly as they happened, lest the memory of events so important should perish, and lest any future historian of the persecutors should corrupt the truth, either by suppressing their offences against God, or the judgment of God against them. To His everlasting mercy ought we to render thanks, that, having at length looked on the earth, He deigned to collect again and to restore His flock, partly laid waste by ravenous wolves, and partly scattered abroad, and to extirpate those noxious wild beasts who had trod down its pastures, and destroyed its resting-places.”

on Luke 10:3The Fathers & the Creeds

About this saying1 paragraph

After 313 Lactantius, who had taught rhetoric at Nicomedia, wrote Of the Manner in Which the Persecutors Died, and in chapter 52 he says why he set the events down.

Cyprian, Lucius Caecilius Firmianus Lactantius

In Their Own Words

Polycarp of Smyrna (died 155)
The Martyrdom of Polycarp, chapter 9

Her answer at the hearing

“I am a Christian.”

on 1 Peter 4:16The Martyrs' Church

About this saying1 paragraph

In 203, the year Kirsch gives, the procurator Hilarianus told Perpetua to offer sacrifice for the emperors. In her own account he then asked, "Are you a Christian?"

Tertullian (died 220)
Apology, chapter 50

The blood of Christians

“The oftener we are mown down by you, the more in number we grow; the blood of Christians is seed.”

on Revelation 12:11The Martyrs' Church

About this saying1 paragraph

In the last chapter of his Apology, at the turn of the third century, Tertullian wrote in Latin "Plures efficimur, quotiens metimur a vobis: semen est sanguis Christianorum."

Cyprian (died 258)
On the Unity of the Church, section 6

The church as mother

“He can no longer have God for his Father, who has not the Church for his mother.”

on Galatians 4:26The Martyrs' Church

About this saying1 paragraph

In 251, the year ANF gives On the Unity of the Church, Cyprian wrote it against the schism of Novatian.

Perpetua of Carthage, Tertullian, Cyprian

Where Historians Disagree

Four questions of the era, each with its holders on both sides.

Ten persecutions, or local trials and two general orders?1 paragraph

Orosius, about 417, set ten persecutions against the ten plagues of Egypt. Augustine replied in City of God 18.52 that the number cannot "be definitely stated." Schaff (1883) counts two that "extended over the empire", those of Decius and Diocletian, and J. B. Rives (1999) gives the received view that the earlier ones were "local affairs."

Did the church make the persecution larger in the telling?1 paragraph

Candida Moss's publisher describes The Myth of Persecution (2013) as showing that there was no sustained effort of three hundred years by the Romans. Collin Garbarino's review in Themelios (2013) answers that she does "ignore or dismiss important evidence."

When did Polycarp die?1 paragraph

J. B. Lightfoot (1889) argued for 155 from the proconsul's year and from 23 February falling on a Saturday that year. Eusebius placed the death in the reign of Marcus Aurelius, in his Church History and, as Lightfoot reads it, in his Chronicle.

Were the catacombs hiding places?1 paragraph

Anton de Waal (1908) writes that Roman law guarded "the inviolability of burial places", so the authorities knew where they lay. L. V. Rutgers (2000) dates their main growth to the fourth century, after the persecutions. De Waal adds that some galleries met sand-pits, which let believers come and go unseen.

What the Persecuted Church Left

The church that came out of Diocletian's persecution had held its confession for two centuries without the law on its side. It carried that confession, and the names of those who died for it, into the age of the creeds.
