DIONYSIUS of ALEXANDRIA (Saint) Bishop (November 17) (3rd century) A celebrated Father of the Church and pupil of Origen, who became Patriarch of Alexandria A.D. 248, and two years afterwards was arrested as a leader of Christians during the fierce persecution under the Emperor Decius. He escaped into hiding in the Libyan Desert, and returned to Alexandria A.D. 251. Under Valerian he was again arrested and again banished; but was recalled and restored under Gallienus. He died at Alexandria A.D. 265. Saint Athanasius styles him “the Doctor of the Catholic Church.” He was ever zealous for the Catholic Faith, and easily justified himself when accused at Rome to his namesake Pope Saint Dionysius. The fragments of his letters still extant are doctrinally very valuable, and bear abundant evidence to his pastoral zeal.
