The Great Persecution

Beginning in 303, Diocletian and his fellow emperors issued four edicts to destroy the churches: meeting places torn down, Scriptures burned, clergy imprisoned, and at last every believer ordered to sacrifice. The persecution was harshest in the East under Galerius and Maximinus Daia. Galerius yielded in 311 and Constantine's favor followed, but within a few years the newly favored catholic party was using the state's power against other Christians.

Forty years of peace

The Calm Before the Storm, 260–303

After Gallienus ended Valerian's persecution in 260, the churches enjoyed about forty years of peace. They grew in the cities and the countryside, in the army and the civil service, even in the emperor's household. Eusebius of Caesarea, who lived through what followed, describes crowded assemblies and larger meeting places rising in every city. At Nicomedia, the emperor's eastern capital, a church building stood on high ground in full view of the palace.

The empire, meanwhile, had been rescued from half a century of civil war by Diocletian, a soldier from Dalmatia who became emperor in 284. To govern so vast a realm he shared power among four rulers: two senior emperors, himself in the East and Maximian in the West, each with a junior colleague, Galerius in the East and Constantius in the West. Diocletian set out to restore Rome's old order in everything: the army, taxes, prices, and religion.

DefinitionTetrarchy

Rule by four. Diocletian's system of two senior emperors (Augusti) and two junior emperors (Caesars), each responsible for part of the empire. It explains why the Great Persecution was fierce in some provinces and mild in others: each ruler enforced the edicts as he chose.

Trouble began at court and in the army. According to Lactantius, a Christian teacher of rhetoric at Nicomedia, the emperor's soothsayers once complained that they could not read the omens at a sacrifice because Christians present had made the sign of the cross. Diocletian ordered everyone in the palace to sacrifice, and soldiers who refused were discharged. Galerius, a bitter enemy of the Christians, pressed for more. Diocletian hesitated, consulted his advisers and the oracle of Apollo at Didyma, and at last agreed.
