The Epistle of Alexander, Bishop of Alexandria to Alexander, Bishop of Constantinople
I have sent you these letters by my son Apion, the deacon; being those of (the ministers in) all Egypt and the Thebaid, also of those of Libya, and the Pentapolis, of Syria, Lycia, Pamphylia, Asia, Cappadocia, and in the other adjoining countries. Whose example you likewise, I trust, will follow. Many kindly attempts have been made by me to gain back those who have been led astray, but no remedy has proved more efficacious in restoring the laity who have been deceived by them and leading them to repentance, than the manifestation of the union of our fellow-ministers. Salute one another, with the brotherhood that is with you. I pray that you may be strong in the Lord, my beloved, and that I may receive the fruit of your love to Christ.
“The following are the name of those who have been anathematized as heretics: among the presbyters, Arius; among the deacons, Achillas, Euzoius, Aïthales, Lucius, Sarmates, Julius, Menas, another Arius, and Helladius.”
Alexander wrote in the same strain to Philogonius, bishop of Antioch, to Eustathius, who then ruled the church of the Berœans, and to all those who defended the doctrines of the Apostles. But Arius could not endure to keep quiet, but wrote to all those whom he believed to agree with him in opinion. His letter to Eusebius, bishop of Nicomedia, is a clear proof that the divine Alexander wrote nothing that was false concerning him. I shall here insert his letter, in order that the names of those who were implicated in his impiety may become generally known.
