Edict of Milan

“We must obey God rather than men.” — Acts 5:29

Background

For three centuries, Rome’s posture toward Christians alternated between tolerance and violent suppression. The persecution that erupted in 303 AD was the most systematic and thorough in the empire’s history.

At the instigation of his co-emperor Galerius, Emperor Diocletian issued the first persecution edict on February 23, 303 AD. Church buildings were razed, Scriptures burned, Christians stripped of civil rights. Those who refused to sacrifice to pagan gods were arrested, tortured, or thrown to the beasts. The persecution lasted approximately eight years — the Great Diocletianic Persecution. (Wikipedia — Diocletianic Persecution)

Galerius, the persecution’s chief architect, fell gravely ill in 311. On April 30, on the verge of death, he issued the Edict of Serdica — also called the Edict of Toleration of 311. He acknowledged that the persecution had not returned Christians to the old gods but had only produced people who believed in nothing. He declared Christianity legal, permitted assembly, and asked Christians to pray for the empire. (Christianity.com — Galerius Issues Edict of Toleration)

The 311 edict was limited. Galerius died immediately after, and the eastern emperor Maximinus Daza resumed persecution. Constantine in the West had already adopted a friendly posture toward Christians — by account, on the eve of his battle against Maxentius in 312, he saw a vision of a cross bearing the words “In hoc signo vinces” — In this sign, conquer.

What Happened

Early in 313, Constantine and his eastern co-emperor Licinius met in Milan to settle imperial religious policy. The meeting was sealed politically by the marriage of Constantine’s half-sister Constantia to Licinius.

The agreement reached there is traditionally called the “Edict of Milan” — a name that is historically imprecise on both counts. It was not an edict, and it was not issued in Milan. It was a letter sent by Licinius on June 13, 313 from Nicomedia to the governors of the eastern provinces. (Britannica — Edict of Milan; Wikipedia — Edict of Milan)

The document’s text is preserved in full by the Latin rhetorician Lactantius in Chapter 48 of De Mortibus Persecutorum (“On the Deaths of the Persecutors”), and in Greek translation by Eusebius in Book X, Chapter 5 of his Church History. Its key provisions:

“No one whatsoever should be denied the opportunity to give his heart to the observance of the Christian religion, or of that religion which he should think best for himself.” — Lactantius, De Mortibus Persecutorum, Ch. 48 (Fordham Internet History Sourcebooks)

“[Churches and assembly places of the Christians] be restored to the said Christians, without demanding money or any other equivalent.” — Ibid.

The agreement declared three things: universal religious freedom across the empire — not for Christianity alone; legal corporate status for the church, allowing it to own property; and the immediate return of all confiscated church buildings and meeting places, with state compensation available to those who had purchased or received them.

The 313 agreement did not make Christianity the state religion. That step came with the Edict of Thessalonica in 380 AD, when Emperor Theodosius I declared Nicene Christianity the empire’s sole legal faith. 313 was religious freedom, not religious monopoly. (Wikipedia — Edict of Milan)

Key Figures

Constantine I (c. 272–337 AD) was the Western Augustus, whose favoritism toward Christians predated 313. The vision before the Battle of Milvian Bridge was the legendary beginning of his relationship with Christianity. He went on to convene the Council of Nicaea (325 AD), fund church construction, and receive baptism on his deathbed. His motivations remain a matter of historical debate — genuine faith, or political calculation?

Licinius (c. 265–325 AD) was the Eastern Augustus who formalized the Milan agreement and issued the document history calls the Edict of Milan. He and Constantine later became rivals; he was defeated in 324 and executed by strangulation.

Galerius (c. 260–311 AD) was the persecution’s primary driver and the author of the 311 edict of toleration. Early Christians read his complete reversal as direct evidence of divine judgment — a persecutor brought low by bodily suffering.

Lactantius (c. 240–320 AD) was a Latin rhetorician who became tutor to Constantine’s son Crispus. His De Mortibus Persecutorum is the primary source for the 313 agreement and an early specimen of divine-retribution theology: persecutors die terrible deaths; those faithful to God are saved. (New Advent — Lactantius)

Eusebius of Caesarea (c. 260–339 AD) had lived through the Great Persecution and became bishop of Caesarea around 313. His response to the 313 agreement was euphoric — Church History Book X opens with hymns of thanksgiving, hailing Constantine as God’s gift to the church. He became the emperor’s court theologian, leaving the most detailed contemporary account of the era and also the first template for how church and state could become fatally intertwined. (CCEL — Eusebius, Church History, Book X)

Outcome and Legacy

The agreement was a genuine liberation after two hundred and fifty years of persecution. Burned Scriptures were copied and distributed again. Demolished church buildings rose from their foundations. Believers who had met in secret came into the open. Eusebius records that Christians celebrated in city after city, weeping and embracing one another.

But the other side of history was equally real.

Religious freedom brought a flood of nominal converts. Constantine reportedly gave white robes and coins to each person baptized, incentivizing conversion with material reward. Tens of thousands of pagans entered the church carrying their existing habits of thought, custom, and worldview. The church’s boundaries blurred. Church leaders entered politics; imperial ambition began shaping ecclesiastical decisions.

After 313, the church was no longer a persecuted minority — it was part of the empire’s power structure. Bishops became politicians. Councils became arenas for power. Emperors presided over theological disputes. By 380, Theodosius I made Nicene Christianity the empire’s sole legal religion and handed the emperor the power to condemn heresy. The church that had been persecuted by the state now used the state to persecute dissenters. (Wikipedia — Constantinian Shift)

Connection to the Recovery

Brother Watchman Nee and Brother Witness Lee both treated 313 as one of the most critical turning points in church history — not for celebration, but for sober warning.

Brother Watchman Nee read this period through Revelation 2:12–17, the letter to Pergamos. He identified the Greek root of “Pergamos” as gamos — marriage — signifying the church’s union with the world:

“The greatest persecution in the entire world was not able to destroy the church. Therefore, Satan changed his method of attack. The world not only ceased to oppose the church, but even the greatest empire on this earth — Rome — accepted Christianity as the state religion… The church was united with the world; therefore, the church became fallen.” — Watchman Nee, The Orthodoxy of the Church, Collected Works Vol. 47, Ch. 7

He connected this era to the strategy of Balaam in Numbers 22–24: force could not bring down Israel, so Balaam counseled seduction through intermarriage with Moab. Mixing, not frontal assault, was the most effective method of destruction. After 313, Satan used the same strategy against the church.

Brother Witness Lee extended this analysis, calling it “Satan’s countermove”:

“Under the rule of Constantine the Great the Roman Empire made Christianity legal, and Christians had the full freedom of worship. Because of the favors he granted the Christians, thousands of pagans were baptized and became Christians in name. These were the tares spoken of in Matthew 13:24-30. That ruined Christianity.” — Witness Lee, The World Situation and God’s Move, Satan’s Countermove (Ministry Samples)

He traced the line from 313 forward: tares flooded in → organic life was replaced by organizational religion → the papal system took shape → by the sixth century, the system was fully established. His conclusion was blunt:

“The Roman Catholic Church killed more genuine Christians than the pagan Roman Empire had killed.” — Ibid.

For both brothers, 313 was not the church’s victory but the beginning of its most dangerous chapter — the world replacing the sword with an embrace. What the Lord’s recovery seeks is a return from this accumulated legacy of mixture: back to the church as the called-out ones (ἐκκλησία), not a religious institution bound to any worldly system.

Significance

313 AD poses a question no generation of the church can sidestep: when the state extends an olive branch, how should the church respond?

Under persecution, the answer is clear — Acts 5:29: we must obey God rather than men. But when the state stops persecuting and begins inviting, funding, and honoring the church, the question becomes harder. The cost of fusion, history shows, is usually the church’s distinctive witness. No more martyrs, because nothing is worth opposing. No more sense of being strangers in the world, because the city is now friendly. No more the way of the cross, because glory and advantage are within reach.

For believers today inside any “Constantinian environment” — whether a state-approved church structure or any framework that conflates worldly success with heavenly calling — the warning of 313 remains sharp. The church has never been destroyed by external persecution. Her deepest crises have come when the world enters her with a friendly face.

In that moment, the answer is not vigilant flight but deeper roots — roots in Christ, not in any earthly security.

“For we do not have here a remaining city, but we seek after the one to come.” — Hebrews 13:14
