Chapter XXV .— The Emperor prepared a Public Table for the Synod, after inviting its Members to Constantinople, and honoring them with Gifts, he exhorted all to be of One Mind, and forwarded to Alexandria and every other place the Decrees of the Holy Synod. At the very time that these decrees were passed by the council, the twentieth anniversary 1138 of the reign of Constantine was celebrated; for it was a Roman custom to have a feast on the tenth year of every reign. The emperor, therefore, thought it to be opportune, and invited the Synod to the festival, and presented suitable gifts to them; and when they prepared to return home, he called them all together, and exhorted them to be of one mind about the faith and at peace among themselves, so that no dissensions might henceforth creep in among them. After many other similar exhortations, he concluded by commanding them to be diligent in prayer, and always to supplicate God for himself, his children, and the empire, and after he had thus addressed those who had come to Nicæa, he bade them farewell. He wrote to the churches in every city, in order that he might make plain to those who had not been present, what had been rectified by the Synod; and especially to the Church of Alexandria he wrote more than this; urging them to lay aside all dissent, and to be harmonious in the faith issued by the Synod; for this could be nothing else than the judgment of God, since it was established by the Holy Spirit from the concurrence of so many and such illustrious high priests, and approved after accurate inquiry and test of all the doubtful points. 1138    This feast, called Vicennalia, is mentioned in Eus. V. C. iii. 15, 16.
