Letter I
(A.D. 323 or 324) Letter of Constantine to Alexander the Bishop and Arius the Presbyter.
Synopsis: Expresses his desire for peace, his hope that they might have helped him in the Donatist troubles, his distress at finding that they, too, were in a broil, his opinion that the matters under discussion are of little moment, and what he thinks they are. He exhorts to unanimity, repeats his opinion that the matters are of little moment, mentions his “copious and constant tears,” and finally concludes.
VICTOR CONSTANTINUS, MAXIMUS AUGUSTUS, to Alexander and Arius.
"I call that God to witness, as well I may, who is the helper of my endeavors, and the Preserver of all men, that I had a twofold reason for undertaking that duty which I have now performed. "MY design then was, first, to bring the diverse judgments formed by all nations respecting the Deity to a condition, as it were, of settled uniformity; and, secondly, to restore to health the system of the world, then suffering under the malignant power of a grievous distemper.

"Finding, then, that the whole of Africa was pervaded by an intolerable spirit of mad folly, through the influence of those who with heedless frivolity had presumed to rend the religion of the people into diverse sects; I was anxious to check this disorder, and could discover no other remedy equal to the occasion, except in sending some of yourselves to aid in restoring mutual harmony among the disputants, after I had removed that common enemy of mankind who had interposed his lawless sentence for the prohibition of your holy synods.
…
"I UNDERSTAND, then, that the origin of the present controversy is this. When you, Alexander, demanded of the presbyters what opinion they severally maintained respecting a certain passage in the Divine law, or rather, I should say, that you asked them something connected with an unprofitable question, then you, Arius, inconsiderately insisted on what ought never to have been conceived at all, or if conceived, should have been buried in profound silence. Hence it was that a dissension arose between you, fellowship was withdrawn, and the holy people, rent into diverse parties, no longer preserved the unity of the one body. Now, therefore, do ye both exhibit an equal degree of forbearance, and receive the advice which your fellow-servant righteously gives. What then is this advice? It was wrong in the first instance to propose such questions as these, or to reply to them when propounded. For those points of discussion which are enjoined by the authority of no law, but rather suggested by the contentious spirit which is fostered by misused leisure, even though they may be intended merely as an intellectual exercise, ought certainly to be confined to the region of our own thoughts, and not hastily produced in the popular assemblies, nor unadvisedly entrusted to the general ear. For how very few are there able either accurately to comprehend, or adequately to explain subjects so sublime and abstruse in their nature? Or, granting that one were fully competent for this, how many people will he convince? Or, who, again, in dealing with questions of such subtle nicety as these, can secure himself against a dangerous declension from the truth? It is incumbent therefore on us in these cases to be sparing of our words, lest, in case we ourselves are unable, through the feebleness of our natural faculties, to give a clear explanation of the subject before us, or, on the other hand, in case the slowness of our hearers' understandings disables them from arriving at an accurate apprehension of what we say, from one or other of these causes the people be reduced to the alternative either of blasphemy or schism.

"RESTORE me then my quiet days, and untroubled nights, that the joy of undimmed light, the delight of a tranquil life, may henceforth be my portion. Else must I needs mourn, with constant tears, nor shall I be able to pass the residue of my days in peace. For while the people of God, whose fellow-servant I am, are thus divided amongst themselves by an unreasonable and pernicious spirit of contention, how is it possible that I shall be able to maintain tranquillity of mind? And I will give you a proof how great my sorrow has been on this behalf. Not long since I had visited Nicomedia, and intended forthwith to proceed from that city to the East. It was while I was hastening towards you, and had already accomplished the greater part of the distance, that the news of this matter reversed my plan, that I might not be compelled to see with my own eyes that which I felt myself scarcely able even to hear. Open then for me henceforward by your unity of judgment that road to the regions of the East which your dissensions have closed against me, and permit me speedily to see yourselves and all other peoples rejoicing together, and render due acknowledgment to God in the language of praise and thanksgiving for the restoration of general concord and liberty to all.

Letter II
(A.D. 325) Letter of Constantine the King, summoning the bishops to Nicæa.
Synopsis: This is translated from a Syriac manuscript which is housed in the British Museum, written in A.D. 501. The letter gives as the reason for choosing Nicæa for the Council the convenience for the European bishops and “the excellent temperature of the air.” This, if genuine, is the letter mentioned by Eusebius in his Life of Constantine.
"That there is nothing more honourable in my sight than the fear of God, I believe is manifest to every man. Now, because the Synod of Bishops at Ancyra, of Galatia, consented at first that it should be, it now seems on many accounts that it would be well for a Synod to assemble at Nicea, a city of Bithynia, both because the Bishops of Italy and the rest of the countries of Europe are coming, and also because of the excellent temperature of the air, and also because I shall be present as a spectator and participator of what is done. Wherefore I signify to you, my beloved brethren, that I earnestly wish all of yon to assemble at this city which is named, that is at Nicea. Let every one of you therefore, considering that which is best, as I before said, be diligent without any delay speedily to come, that he may be present in his own person as a spectator of what is done. God keep you, my beloved brethren."
Letter III
(From B. H. Cowper’s, Syriac Miscellanies, The Council Of Nicea. Extracts From The Codex Syriacus 38 In The Imperial Library At Paris, p.249) (A.D. 325) Letter of Constantine to the churches after the Council of Nicæa.
Synopsis: Dwells on the harmonious result, especially respecting the Easter controversy, and commends to the bishops to observe what the Council has decreed.
CONSTANTINUS AUGUSTUS, to the Churches.
"Having had full proof, in the general prosperity of the empire, how great the favor of God has been towards us, I have judged that it ought to be the first object of my endeavors, that unity of faith, sincerity of love, and community of feeling in regard to the worship of Almighty God, might be preserved among the highly favored multitude who compose the Catholic Church. And, inasmuch as this object could not be effectually and certainly secured, unless all, or at least the greater number of the bishops were to meet together, and a discussion of all particulars relating to our most holy religion to take place; for this reason as numerous an assembly as possible has been convened, at which I myself was present, as one among yourselves (and far be it from me to deny that which is my greatest joy, that I am your fellow-servant), and every question received due and full examination, until that judgment which God, who sees all things, could approve, and which tended to unity and concord, was brought to light, so that no room was left for further discussion or controversy in relation to the faith.
…
"RECEIVE, then, with all willingness this truly Divine injunction, and regard it as in truth the gift of God. For whatever is determined in the holy assemblies of the bishops is to be regarded as indicative of the Divine will. As soon, therefore, as you have communicated these proceedings to all our beloved brethren, you are bound from that time forward to adopt for yourselves, and to enjoin on others the arrangement above mentioned, and the due observance of this most sacred day; that whenever I come into the presence of your love, which I have long desired, I may have it in my power to celebrate the holy feast with you on the same day, and may rejoice with you on all accounts, when I behold the cruel power of Satan removed by Divine aid through the agency of our endeavors, while your faith, and peace, and concord everywhere flourish. God preserve you, beloved brethren.
