1. Since the body of the Catholic Church is one, and it is commanded in Holy Scripture that we should keep the bond of unanimity and peace, it follows that we should write and signify to one another the things which are done by each of us; that whether one member suffer or rejoice we may all either suffer or rejoice with one another. In our diocese, then, not so long ago, there have gone forth lawless men, and adversaries of Christ, teaching men to apostatize; which thing, with good right, one might suspect and call the precursor of Antichrist. I indeed wished to cover the matter up in silence, that so perhaps the evil might spend itself in the leaders of the heresy alone, and that it might not spread to other places and defile the ears of any of the more simple-minded. But since Eusebius, the present bishop of Nicomedia, imagining that with him rest all ecclesiastical matters, because, having left Berytus and cast his eyes upon the church of the Nicomedians, and no punishment has been inflicted upon him, he is set over these apostates, and has undertaken to write everywhere, commending them, if by any means he may draw aside some who are ignorant to this most disgraceful and Antichristian heresy; it became necessary for me, as knowing what is written in the law, no longer to remain silent, but to announce to you all, that you may know both those who have become apostates, and also the wretched words of their heresy; and if Eusebius write, not to give heed to him.
