A layman martyred at Nicomedia in 303 with Migdonus, Eugene, and other companions at the very outbreak of Diocletian’s persecution of the Church.

Saint Maximus of Nicomedia in Bithynia was a layman put to death in 303 alongside a group of fellow Christians, including the priest Migdonus and several members of Emperor Diocletian’s own household. Their deaths came in the opening days of the Great Persecution, after fires in the imperial palace at Nicomedia were blamed on Christians and triggered a wave of arrests. Maximus’s witness, delivered within the emperor’s own residence, stands among the very first martyrdoms of the empire’s harshest campaign against the Church.

Who Was Saint Maximus of Nicomedia in Bithynia?

Maximus of Nicomedia was a layman of the imperial city of Nicomedia, put to death in the year 303 alongside a group of fellow Christians that included the priest Migdonus and several members of the emperor Diocletian’s own household staff. Nicomedia served as one of Diocletian’s chief residences, which meant that when persecution began, it began close to the throne itself.

Historical Setting

In February 303, an edict against Christians was posted in Nicomedia, and shortly afterward fires in the imperial palace, blamed on Christians, triggered a wave of arrests and executions among the household. Maximus and his companions, Migdonus, Eugene, Domna, Mardonius, Peter, Esmaragdus, and Hilary, are remembered together as part of that first, violent phase of what became the empire’s last and most severe persecution.

Why the Church Remembers Saint Maximus of Nicomedia in Bithynia

The Church honors Maximus because his death belongs to the opening hours of a persecution that would claim thousands of lives across the empire over the following decade, and because he and his companions died not in some distant province but inside the emperor’s own residence, a witness delivered at the very center of imperial power.

Canonization and Feast Day

No formal canonization process is recorded for Maximus of Nicomedia, which is entirely expected for a martyr of 303. His veneration, shared with his named companions, rests on the ancient and continuous liturgical memory of the Eastern and Western Churches, recorded in the martyrologies long before any formal canonization procedure existed.

What Catholics Can Learn Today

Maximus and his companions remind us that persecution often begins closest to power, among people whose ordinary daily proximity to authority did not protect them and may even have made them more visible targets. Their steadiness under that pressure is a model for remaining faithful precisely where faith is least convenient.

A Prayer to Saint Maximus of Nicomedia in Bithynia

Saint Maximus, who with your companions bore witness to Christ within the very household of the emperor who sought to destroy the Church, pray for those who must live their faith quietly amid hostile or indifferent surroundings. Grant us your constancy when fidelity is costly. Amen.
