The Synodical Letter. 
To the right honourable lords our right reverend brethren and colleagues, Damasus, Ambrosius, Britton, Valerianus, Ascholius, Anemius, Basilius and the rest of the holy bishops assembled in the great city of Rome, the holy synod of the orthodox bishops assembled at the great city of Constantinople sends greeting in the Lord.
To recount all the sufferings inflicted on us by the power of the Arians, and to attempt to give information to your reverences, as though you were not already well acquainted with them, might seem superfluous. For we do not suppose your piety to hold what is befalling us as of such secondary importance as that you stand in any need of information on matters which cannot but evoke your sympathy. Nor indeed were the storms which beset us such as to escape notice from their insignificance. Our persecutions are but of yesterday. The sound of them still rings in the ears alike of those who suffered them and of those whose love made the sufferers' pain their own. It was but a day or two ago, so to speak, that some released from chains in foreign lands returned to their own churches through manifold afflictions; of others who had died in exile the relics were brought home; others again, even after their return from exile, found the passion of the heretics still at the boiling heat, and, slain by them with stones as was the blessed Stephen, met with a sadder fate in their own than in a stranger's land. Others, worn away with various cruelties, still bear in their bodies the scars of their wounds and the marks of Christ. Who could tell the tale of fines, of disfranchisements, of individual confiscations, of intrigues, of outrages, of prisons? In truth all kinds of tribulation were wrought out beyond number in us, perhaps because we were paying the penalty of sins, perhaps because the merciful God was trying us by means of the multitude of our sufferings. For these all thanks to God, who by means of such afflictions trained his servants and, according to the multitude of his mercies, brought us again to refreshment. We indeed needed long leisure, time, and toil to restore the church once more, that so, like physicians healing the body after long sickness and expelling its disease by gradual treatment, we might bring her back to her ancient health of true religion. It is true that on the whole we seem to have been delivered from the violence of our persecutions and to be just now recovering the churches which have for a long time been the prey of the heretics. But wolves are troublesome to us who, though they have been driven from the fold, yet harry the flock up and down the glades, daring to hold rival assemblies, stirring seditious among the people, and shrinking from nothing which can do damage to the churches. So, as we have already said, we needs must labour all the longer. Since, however, you showed your brotherly love to us by inviting us (as though we were your own members) by the letters of our most religious emperor to the synod which you are gathering by divine permission at Rome, to the end that since we alone were then condemned to suffer persecution, you should not now, when our emperors are at one with us as to true religion, reign apart from us, but that we, to use the Apostle's phrase, should reign with you, our prayer was, if it were possible, all in company to leave our churches, and rather gratify our longing to see you than consult their needs.
