A layman martyred at Tarsus in 304 alongside Saints Tharacus and Probus, whose court record is among the most historically reliable of ancient martyr accounts.

Saint Andronicus was a Christian layman put to death at Tarsus in Cilicia in the year 304, together with his companions Saint Tharacus and Saint Probus, during the Diocletianic persecution. Their martyrdom is unusually well documented because the surviving account draws directly on the official transcript of their interrogation, making it one of the more historically trustworthy records to survive from the era of Roman persecution.

Who Was Saint Andronicus?

Saint Andronicus was a layman martyred at Tarsus, the provincial capital of Cilicia in southeastern Asia Minor, in the year 304, alongside his companions Tharacus and Probus. Unusually for a martyr of this period, the account of his trial is based closely on what appears to be genuine court records of the proceedings against him, giving historians unusual confidence in its basic outline.

Historical Setting

The year 304 fell within the most intense phase of the persecution launched by Diocletian in 303, when provincial governors across the empire actively sought out Christians for interrogation and execution. Tarsus, an important administrative center, saw the trial of Andronicus and his companions conducted with the formal legal procedure typical of Roman provincial justice, which is precisely why a comparatively reliable transcript-based account of it survived.

Why the Church Remembers Saint Andronicus

Andronicus is remembered, together with Tharacus and Probus, for the calm persistence the three showed under repeated interrogation and torture, refusing each time to offer the sacrifice demanded of them. Their story is often cited by historians as offering a rare, relatively unembellished window into how such trials actually proceeded.

Canonization and Feast Day

No formal canonization process considered this ancient martyr. His veneration, alongside that of Tharacus and Probus, rests on the ancient and well-attested record of their trial and death, received into the Roman Martyrology.

What Catholics Can Learn Today

The unusually reliable record of Andronicus’s trial lets modern readers see, in close to real detail, the patient, repeated courage that martyrdom actually required: not a single dramatic moment, but multiple rounds of pressure endured one after another. His example reminds Catholics that fidelity under sustained pressure, not only in a single crisis, is itself heroic.

A Prayer to Saint Andronicus

Saint Andronicus, who endured repeated trial and torture with Tharacus and Probus rather than deny Christ, pray for us. Grant us your patient endurance under pressure that does not relent, that we too may hold firm through every renewed test of our faith. Amen.
