The author of the Arian heresy was Arius, a native of Lybia, and a priest of Alexandria, who, in A.D. 318, began to publish his errors. He was condemned by a council of Lybian and Egyptian bishops, and that sentence was confirmed by the Council of Nice, A.D. 325. After the death of Constantine the Great, the Arians found means to ingratiate themselves into the favor of the emperor Constantinus, his son and successor in the east; and hence a persecution was raised against the orthodox bishops and clergy. The celebrated Athanasius, and other bishops, were banished, and their sees filled with Arians.

In Egypt and Lybia, thirty bishops were martyred, and many other Christians cruelly tormented; and, A.D. 386, George, the Arian bishop of Alexandria, under the authority of the emperor, began a persecution in that city and its environs, and carried it on with the most infernal severity. He was assisted in his diabolical malice by Catophonius, governor of Egypt; Sebastian, general of the Egyptian forces; Faustinus, the treasurer; and Heraclius, a Roman officer.

The persecutions now raged in such a manner that the clergy were driven from Alexandria, their churches were shut, and the severities practiced by the Arian heretics were as great as those that had been practiced by the pagan idolaters. If a man, accused of being a Christian, made his escape, then his whole family were massacred, and his effects confiscated.
