Saint Peter illustriously occupied the throne of Alexandria for twelve years, and, as Eusebius says, “was a divine example of a bishop on account of the excellence of his life and his study of the sacred Scriptures” (see Eusebius, Eccl. Hist., Book VII, 3 2; Book VIII 11, 13; and Book IX, 6). He excommunicated Arius for his sympathy with the Meletian schism. When Arius learned that Saint Peter had been imprisoned, he sent many priests and deacons to him, asking that he receive him back into the communion of the Church before his martyrdom. When the ambassadors of Arius, who had not, like Saint Peter, perceived the ruin he would engender, were astonished at the vehemence with which Saint Peter refused to receive Arius again, he revealed to them a dread vision he had seen, in which the Master Christ had appeared to him as a child wearing a garment torn from head to foot. When Saint Peter asked the Lord who rent His garment, the Lord answered that it was Arius, and that he must not be received back into communion. The holy hieromartyr Peter was beheaded during the reign of Maximinus in the year 312; he is called the “Seal of the Martyrs,” because he was the last Bishop of Alexandria to suffer martyrdom under the pagan Emperors. His successors to the throne of Alexandria, Saints Alexander and Athanasius the Great, brought to final victory the battle against Arius’ heresy which Saint Peter had begun.
