Division begins in the Church from this Controversy; and Alexander Bishop of Alexandria excommunicates Arius and his Adherents
Some one accordingly asked them whether the Word of God could be changed, as the devil has been? And they feared not to say, 'Yes, he could; for being begotten, he is susceptible of change.' We then, with the bishops of Egypt and Libya, being assembled together to the number of nearly a hundred, have anathematized Arius for his shameless avowal of these heresies, together with all such as have countenanced them. Yet the partisans of Eusebius have received them; endeavoring to blend falsehood with truth, and that which is impious with what is sacred. But they shall not prevail, for the truth must triumph; and 'light has no fellowship with darkness, nor has Christ any concord with Belial.' Who ever heard such blasphemies? Or what man of any piety is there now hearing them that is not horror-struck, and stops his ears, lest the filth of these expressions should pollute his sense of hearing? Who that hears John saying, 'In the beginning was the Word,' does not condemn those that say, 'There was a period when the Word was not'? Or who, hearing in the Gospel of 'the only-begotten Son,' and that 'all things were made by him,' will not abhor those that pronounce the Son to be one of the things made? How can he be one of the things which were made by himself? Or how can he be the only-begotten, if he is reckoned among created things? And how could he have had his existence from nonentities, since the Father has said, 'My heart has indited a good matter'; and 'I begot you out of my bosom before the dawn'? Or how is he unlike the Father's essence, who is 'his perfect image,' and 'the brightness of his glory' and says: 'He that has seen me, has seen the Father?'? Again how if the Son is the Word and Wisdom of God, was there a period when he did not exist? For that is equivalent to their saying that God was once destitute both of Word and Wisdom. How can he be mutable and susceptible of change, who says of himself, 'I am in the Father, and the Father in me'; and 'I and the Father are one'; and again by the Prophet, 'Behold me because I am, and have not changed'? But if any one may also apply the expression to the Father himself, yet would it now be even more fitly said of the Word; because he was not changed by having become man, but as the Apostle says, 'Jesus Christ, the same yesterday, today, and forever.' But what could persuade them to say that he was made on our account, when Paul has expressly declared that 'all things are for him, and by him'? One need not wonder indeed at their blasphemous assertion that the Son does not perfectly know the Father; for having once determined to fight against Christ, they reject even the words of the Lord himself, when he says, 'As the Father knows me, even so know I the Father.' If therefore the Father but partially knows the Son, it is manifest that the Son also knows the Father but in part. But if it would be improper to affirm this, and it be admitted that the Father perfectly knows the Son, it is evident that as the Father knows his own Word, so also does the Word know his own Father, whose Word he is. And we, by stating these things, and unfolding the divine Scriptures, have often confuted them: but again as chameleons they were changed, striving to apply to themselves that which is written, 'When the ungodly has reached the depths of iniquity, he becomes contemptuous.' Many heresies have arisen before these, which exceeding all bounds in daring, have lapsed into complete infatuation: but these persons, by attempting in all their discourses to subvert the Divinity of The Word, as having made a nearer approach to Antichrist, have comparatively lessened the odium of former ones. Wherefore they have been publicly repudiated by the Church, and anathematized. We are indeed grieved on account of the perdition of these persons, and especially so because, after having been previously instructed in the doctrines of the Church, they have now apostatized from them. Nevertheless we are not greatly surprised at this, for Hymenæus and Philetus fell in like manner; and before them Judas, who had been a follower of the Saviour, but afterwards deserted him and became his betrayer. Nor were we without forewarning respecting these very persons: for the Lord himself said: 'Take heed that no man deceive you: for many shall come in my name, saying, I am Christ: and shall many deceive many'; and 'the time is at hand; Go ye not therefore after them.' And Paul, having learned these things from the Saviour, wrote, 'That in the latter times some should apostatize from the faith, giving heed to deceiving spirits, and doctrines of devils,' who pervert the truth. Seeing then that our Lord and Saviour Jesus Christ has himself enjoined this, and has also by the apostle given us intimation respecting such men, we having ourselves heard their impiety have in consequence anathematized them, as we before said, and declared them to be alienated from the Catholic Church and faith. Moreover we have intimated this to your piety, beloved and most honored fellow-ministers, in order that you might neither receive any of them, if they should presume to come to you, nor be induced to put confidence in Eusebius, or any other who may write to you about them. For it is incumbent on us who are Christians, to turn away from all those who speak or entertain a thought against Christ, as from those who are resisting God, and are destroyers of the souls of men: neither does it become us even 'to salute such men,' as the blessed John has prohibited, 'lest we should at any time be made partakers of their sins.' Greet the brethren which are with you; those who are with me salute you.
Upon Alexander's thus addressing the bishops in every city, the evil only became worse, inasmuch as those to whom he made this communication were thereby excited to contention. And some indeed fully concurred in and subscribed to the sentiments expressed in this letter, while others did the reverse. But Eusebius, bishop of Nicomedia, was beyond all others moved to controversy, inasmuch as Alexander in his letter had made a personal and censorious allusion to him. Now at this juncture Eusebius possessed great influence, because the emperor resided at Nicomedia. For in fact Diocletian had a short time previously built a palace there. On this account therefore many of the bishops paid their court to Eusebius. And he repeatedly wrote both to Alexander, that he might set aside the discussion which had been excited, and again receive Arius and his adherents into communion; and also to the bishops in each city, that they might not concur in the proceedings of Alexander. By these means confusion everywhere prevailed: for one saw not only the prelates of the churches engaged in disputing, but the people also divided, some siding with one party, and some with the other. To so disgraceful an extent was this affair carried, that Christianity became a subject of popular ridicule, even in the very theatres. Those who were at Alexandria sharply disputed about the highest points of doctrine, and sent deputations to the bishops of the several dioceses; while those who were of the opposite faction created a similar disturbance.
With the Arians the Melitians mingled themselves, who a little while before had been separated from the Church: but who these [Melitians] are must now be stated.
