How Christianity Almost Vanished in 303 AD

February 23, AD 303: The Edict Against Christianity

On February 23, AD 303, Gaius Aurelius Valerius Diocletianus, Augustus and Pontifex Maximus, proclaimed the suppression of Christianity. Churches were ordered to close, sacred texts were to be burned, and Christians of rank were to be demoted. Christian freedmen could be enslaved. Within hours, the church in Nicomedia, Diocletian’s capital, was demolished. This marked the beginning of the Great Persecution.

Early Roman Persecution of Christianity

The persecution demonstrated the Roman state’s efforts to suppress Christianity while highlighting the empire’s political and religious challenges. Diocletian, a proponent of Roman tradition, had previously issued edicts such as banning Egyptian sibling marriages in AD 295 and targeting the Manichaean religion. Manichaean leaders were executed, and their followers faced severe punishments, reflecting Diocletian’s aim to uphold ancestral customs.

Christian Beliefs and Roman Hostility

Traditional Roman society viewed Christians as subversive due to their worship of a single god and refusal to participate in state festivals and sacrifices. This refusal was perceived as antisocial and treasonous, as the traditional gods were believed to protect the empire. Initial anti-Christian sentiment occasionally led to mob violence, but systematic persecution began under Emperor Decius in the mid-3rd century.

The Decian Persecution

Emperor Decius ordered universal sacrifices to the gods, requiring all citizens to participate and receive certification of compliance. Christians who refused were detained and faced exile or execution. The Decian persecution set a precedent for associating imperial authority with traditional religion, intensifying hostility toward Christians during periods of crisis.

Diocletian’s Great Persecution

Diocletian’s persecution was the most comprehensive Roman campaign against Christianity. Prompted by Galerius, his junior co-ruler, and the oracle of Apollo at Didyma, Diocletian issued the first edict on February 23, AD 303, coinciding with the festival of Terminalia. Churches across the provinces were demolished, starting in Palestine, and Christians were interrogated in Carthage within months.

Regional Variations

The persecution varied in severity across the empire. Eastern provinces under Diocletian and Galerius saw intense enforcement, while Constantius, governing in the west, largely ignored the edict in Britain, Gaul, and Spain.

Successive Edicts

Subsequent edicts ordered the arrest of Christian clergy, leading to overcrowded prisons and systematic torture to compel sacrifices to the gods. These efforts were briefly paused in AD 304 for Diocletian’s 20th anniversary celebrations, only to resume with renewed vigor.

The Reign of Maximinus

In AD 305, Diocletian abdicated, and Galerius assumed senior authority, appointing Maximinus as junior emperor in the east. Maximinus, a devout supporter of traditional polytheism, intensified the persecution. Measures included distributing texts discrediting Christianity and mandating that goods and public spaces be contaminated with sacrificial blood, rendering them inaccessible to Christians.

The Decline of the Great Persecution

By AD 311, popular support for the persecution waned, with growing sympathy for Christian victims. Executions were moved outside cities to prevent unrest. Galerius, dying of cancer, issued an edict of toleration in AD 311, allowing Christians to worship under conditions of maintaining public peace. Maximinus followed with a similar edict, and Constantine’s Edict of Milan in AD 313 officially ended the persecution.

Consequences of the Persecution

The Great Persecution resulted in significant Christian casualties and suffering, including torture, exile, and enslavement. North Africa experienced lasting schisms within the Christian community. The resistance forged a stronger sense of purpose within Christianity, and martyrs became revered figures. The persecution indirectly contributed to the rise of monasticism and strengthened the faith in the years preceding Constantine’s conversion.

Today, the Era of the Martyrs, beginning with Diocletian’s accession, remains a chronological marker for Coptic and Ethiopian churches.
