Who Was Saint Peter of Alexandria the Layman?

This Peter of Alexandria is recorded as a layman put to death in that city at some point during the third century, a period that saw several distinct waves of persecution rather than a single sustained one. No further detail of his trade, family, or the specific circumstances of his death survives in the sources used for this page, and the imprecise dating reflects genuine uncertainty in the surviving record rather than an oversight.

Historical Setting

Third-century Alexandria endured persecution under Decius in the 250s, under Valerian shortly after, and again under Diocletian at the century’s end, with periods of relative calm between; the city’s large Christian population meant it was repeatedly a focal point for both persecution and vigorous Christian intellectual and pastoral life, including the famous catechetical school associated with Origen and Clement of Alexandria.

Why the Church Remembers Saint Peter of Alexandria

This Peter is remembered simply as one of Alexandria’s many third-century martyrs, sharing a name with the great bishop who would be martyred in the same city a generation or more later, a coincidence that reflects how common the name Peter had already become among Egyptian Christians by this period.

Canonization and Feast Day

No formal canonisation process is recorded for this Peter of Alexandria. His veneration rests on the ancient and immemorial local cult of the Alexandrian martyrs, preserved through the Church’s liturgical memory.

What Catholics Can Learn Today

The uncertainty around this Peter’s exact dates is itself an honest reminder that not every detail of the Church’s ancient martyrology can be pinned down precisely, and that faithful veneration does not require false certainty about facts genuinely lost to time.
