Documents connected with the charges of the Meletians against S. Athanasius
Being earnestly desirous of peace and union with the Catholic Church, over which by the grace of God you preside, and wishing to submit ourselves to the Canon of the Church, according to the ancient rule, we write unto you, dearly beloved Pope, and declare in the name of the Lord, that we will not for the future hold communion with those who continue in schism, and are not yet at peace with the Catholic Church, whether Bishops, Presbyters, or Deacons. Neither will we take part with them if they wish to establish anything in a Council; neither will we send letters of peace unto them nor receive such from them; neither yet without the consent of you, the bishop of the metropolis, will we publish any determination concerning Bishops, or on any other general ecclesiastical question; but we will yield obedience to all the canons that have heretofore been ordained, after the example of the Bishops Ammonian, Tyrannus, Plusian, and the rest. Wherefore we beseech your goodness to write to us speedily in answer, and likewise to our fellow-ministers concerning us, informing them that we will henceforth abide by the fore-mentioned resolution and will be at peace with the Catholic Church, and at unity with our fellow-ministers in the [various] districts. And we are persuaded that your prayers, being acceptable unto God, will so prevail with Him, that this peace shall be firm and indissoluble unto the end, according to the will of God the Lord of all, through Jesus Christ our Lord.
The sacred Ministry that is under you, we and those that are with us salute. Very shortly, if God permit, we will come to visit your goodness. I, Arsenius, pray for your health in the Lord for many years, most blessed Pope.
70. But a stronger and clearer proof of the calumny against us is the recantation of John, of which the most God-beloved Emperor Constantine of blessed memory is a witness, for knowing how John had accused himself, and having received letters from him expressing his repentance, he wrote to him as follows.
Constantine, Maximus, Augustus to John.
The letters which I have received from your prudence were extremely pleasing to me, because I learned from them what I very much longed to hear, that you had laid aside every petty feeling, had joined the Communion of the Church as became you, and were now in perfect concord with the most reverend Bishop Athanasius. Be assured therefore that so far I entirely approve of your conduct; because, giving up all skirmishing, you have done that which is pleasing to God, and have embraced the unity of His Church. In order therefore that you may obtain the accomplishment of your wishes, I have thought it right to grant you permission to enter the public conveyance, and to come to the court of my clemency. Let it then be your care to make no delay; but as this letter gives you authority to use the public conveyance, come to me immediately, that you may have your desires fulfilled, and by appearing in my presence may enjoy that pleasure which it is fit for you to receive. May God preserve you continually, dearly beloved brother.
