Bp. of Sardis. Little is known about his life. He was a prolific writer, but only fragments of his works were known until 1940, when one preserved on papyrus was published. The main theme of the Peri Pascha (‘On the Pasch’) is the new Pasch inaugurated by Christ. In it there is much polemic against the Jews and an anti-Gnostic insistence on the true humanity of Christ. Feast day, 1 Apr.
