Sacred History, Book 2
Hilary at the Council of Seleucia
In the meantime, in the East, following the example of the West, the emperor ordered almost all the bishops to assemble at Seleucia, a town of Isauria. At that time Hilary, who was now spending the fourth year of his exile in Phrygia, was compelled to be present among the other bishops, and the deputy and the governor provided him with the means of public transport. The emperor had given no special orders about him. But the judges simply followed the general order by which they were commanded to gather all the bishops to the council, and sent him along with the rest who were willing to go. This was done, I imagine, by the special arrangement of God, so that a man most deeply instructed in divine things might be present when the faith was to be discussed.
When he arrived at Seleucia he was received with great favor, and drew the minds and affections of everyone to himself. The first question put to him concerned the real faith of the Gauls. For at that time the Arians had spread evil reports about us, and the Easterners suspected us of having taken up the belief of Sabellius, that the unity of the one God was distinguished only by a threefold name. But after he had set out his faith in agreement with the conclusions the fathers had reached at Nicaea, he bore witness on behalf of the Westerners. So, with everyone’s mind satisfied, he was admitted to communion, and being received into their fellowship, he was added to the council. Then they set to work, and the founders of the wicked heresy were exposed and cut off from the body of the church. Among them were George of Alexandria, Acacius, Eudoxius, Uranius, Leontius, Theodosius, Evagrius, and Theodulus. When the synod was over, a delegation was appointed to go to the emperor and tell him what had been done. Those who had been condemned also went to the emperor, relying on the power of their allies and on a common cause with the ruler.
