Book I, Ch. 7 — The Emperor Constantine being grieved at the Disturbance of the Churches, sends Hosius the Spaniard to Alexandria, exhorting the Bishop and Arius to Reconciliation and Unity.

When the emperor was made acquainted with these disorders, he was very deeply grieved; and regarding the matter as a personal misfortune, immediately exerted himself to extinguish the conflagration which had been kindled, and sent a letter to Alexander and Arius by a trustworthy person named Hosius, who was bishop of Cordova, in Spain. The emperor greatly loved this man and held him in the highest estimation. It will not be out of place to introduce here a portion of this letter, the whole of which is given in the life of Constantine by Eusebius. Victor Constantine Maximum Augustus to Alexander and Arius. I am informed that your present controversy originated thus. When you, Alexander, inquired of your presbyters what each thought on a certain inexplicable passage of the written Word, rather on a subject improper for discussion; and you, Arius, rashly gave expression to a view of the matter such as ought either never to have been conceived, or when suggested to your mind, it became you to bury it in silence. This dispute having thus been excited among you, communion has been denied; and the most holy people being rent into two factions, have departed from the harmony of the common body. Wherefore let each one of you, showing consideration for the other, listen to the impartial exhortation of your fellow-servant. And what counsel does he offer? It was neither prudent at first to agitate such a question, nor to reply to such a question when proposed: for the claim of no law demands the investigation of such subjects, but the idle useless talk of leisure occasions them. And even if they should exist for the sake of exercising our natural faculties, yet we ought to confine them to our own consideration, and not incautiously bring them forth in public assemblies, nor thoughtlessly confide them to the ears of everybody. Indeed how few are capable either of adequately expounding, or even accurately understanding the import of matters so vast and profound! And even if any one should be considered able to satisfactorily accomplish this, how large a portion of the people would he succeed in convincing? Or who can grapple with the subtilties of such investigations without danger of lapsing into error? It becomes us therefore on such topics to check loquacity, lest either on account of the weakness of our nature we should be incompetent to explain the subject proposed; or the dull understanding of the audience should make them unable to apprehend clearly what is attempted to be taught: and in the case of one or the other of these failures, the people must be necessarily involved either in blasphemy or schism. Wherefore let an unguarded question, and an inconsiderate answer, on the part of each of you, procure equal forgiveness from one another. No cause of difference has been started by you bearing on any important precept contained in the Law; nor has any new heresy been introduced by you in connection with the worship of God; but ye both hold one and the same judgment on these points, which is the Creed. Moreover, while you thus pertinaciously contend with one another about matters of small or scarcely the least importance, it is unsuitable for you to have charge of so many people of God, because you are divided in opinion: and not only is it unbecoming, but it is also believed to be altogether unlawful. In order to remind you of your duty by an example of an inferior kind, I may say: you are well aware that even the philosophers themselves are united under one sect. Yet they often differ from each other on some parts of their theories: but although they may differ on the very highest branches of science, in order to maintain the unity of their body, they still agree to coalesce. Now, if this is done amongst them, how much more equitable will it be for you, who have been constituted ministers of the Most High God, to become unanimous with one another in such a religious profession. But let us examine with closer consideration, and deeper attention, what has been already stated. Is it right on account of insignificant and vain contentions between you about words, that brethren should be set in opposition against brethren; and that the honorable communion should be distracted by unhallowed dissension, through our striving with one another respecting things so unimportant, and by no means essential? These quarrels are vulgar and rather consistent with puerile thoughtlessness, than suitable to the intelligence of priests and prudent men. We should spontaneously turn aside from the temptations of the devil. The great God and Saviour of us all has extended to all the common light. Under his providence, allow me, his servant, to bring this effort of mine to a successful issue; that by my exhortation, ministry, and earnest admonition, I may lead you, his people, back to unity of communion.
