Athanasius Ap. con Ar., 49

49. Since then it became us not to hold our peace, nor to pass over unnoticed their calumnies, imprisonments, murders, wounds, conspiracies by means of false letters, outrages, stripping of the virgins, banishments, destruction of the Churches, burnings, translations from small cities to larger dioceses, and above all, the rising of the ill-named Arian heresy by their means against the orthodox faith; we have therefore pronounced our dearly beloved brethren and fellow-ministers Athanasius, Marcellus, and Asclepas, and those who minister to the Lord with them, to be innocent and clear of offence, and have written to the diocese of each, that the people of each Church may know the innocence of their own Bishop, and may esteem him as their Bishop and expect his coming.

And as for those who like wolves [620] have invaded their Churches, Gregory at Alexandria, Basil at Ancyra, and Quintianus at Gaza, let them neither give them the title of Bishop, nor hold any communion at all with them, nor receive letters [621] from them, nor write to them. And for Theodorus, Narcissus, Acacius, Stephanus, Ursacius, Valens, Menophantus, and George, although the last from fear did not come from the East, yet because he was deposed by the blessed Alexander, and because both he and the others were connected with the Arian madness, as well as on account of the charges which lie against them, the holy Council has unanimously deposed them from the Episcopate, and we have decided that they not only are not Bishops, but that they are unworthy of holding communion with the faithful.

For they who separate the Son and alienate the Word from the Father, ought themselves to be separated from the Catholic Church and to be alien from the Christian name. Let them therefore be anathema to you, because they have corrupted the word of truth [622] .’ It is an Apostolic injunction [623] , If any man preach any other Gospel unto you than that ye have received, let him be accursed.’ Charge your people that no one hold communion with them, for there is no communion of light with darkness; put away from you all these, for there is no concord of Christ in Belial [624] . And take heed, dearly beloved, that ye neither write to them, nor receive letters from them; but desire rather, brethren and fellow-ministers, as being present in spirit [625] with our Council, to assent to our judgments by your subscriptions [626] , to the end that concord may be preserved by all our fellow-ministers everywhere. May Divine Providence protect and keep you, dearly beloved brethren, in sanctification and joy.

I, Hosius, Bishop, have subscribed this, and all the rest likewise. This is the letter which the Council of Sardica sent to those who were unable to attend, and they on the other hand gave their judgment in accordance; and the following are the names both of those Bishops who subscribed in the Council, and of the others also.
