His death falls near the end of the Diocletianic persecution, in its final and especially harsh phase under the eastern emperor Maximinus Daia, who continued to enforce anti-Christian edicts in Egypt and the East even as persecution was beginning to ease elsewhere in the Roman world.

Why the Church Remembers Saint Dius of Alexandria

He is remembered as a priest who died alongside two companions in the last years of the empire-wide persecutions, part of the final generation of martyrs before Constantine’s Edict of Milan brought toleration to the Church in 313.

What Catholics Can Learn Today

Dying so near the end of the persecutions, before the peace Constantine would soon grant the Church, his witness is a reminder of how unpredictable the timing of deliverance can be, and how faith was still asked to hold firm right up to the last hour of trial.

A Prayer to Saint Dius of Alexandria

Saint Dius, priest who with Faustus and Ammon remained faithful to the end of a long persecution, pray for perseverance in all who wait for relief from hardship. Amen.
