Pierius was a third-century Christian presbyter and philosopher from Alexandria. He likely served as the head of the Catechetical School of Alexandria alongside Achillas during the episcopate of Theonas. Known for his expertise in preaching and biblical exegesis, he was sometimes referred to as "Origen the Younger." After surviving the Diocletianic Persecution, he moved to Rome, where he lived until his death after the year 309.
Life and works
As a scholar, Pierius authored a collection of twelve treatises or sermons. His surviving fragments include commentaries on the Gospel of Luke, an Easter sermon regarding Hosea, a discourse on the Mother of God, and a eulogy for his disciple, Pamphilus. Some of his theological writings contain ideas similar to those of Origen, such as the pre-existence of souls and the subordination of the Holy Spirit.
Veneration
He is recognized as a saint in both Catholic and Orthodox traditions. While some historical accounts describe him as a martyr, others suggest he merely endured significant suffering for his faith rather than dying for it. His memory is commemorated annually on 4 November, as noted in the Roman Martyrology.
