The Ecclesiastical History Of Scholasticus by Socrates Scholasticus
Chapter IV.--The Macedonians hold a Synod at Lampsacus, during a Period of Both Secular and Ecclesiastical Agitation; and after confirming the Antiochian Creed, and anathematizing that promulgated at Ariminum, they again ratify the Deposition of Acacius a
While these events were taking place there could be no peace either in the church or in the state. Now those who had been empowered by the emperor to hold a council assembled at Lampsacus in the consulate just mentioned: this was seven years after the council of Seleucia. There, after confirming the Antiochian Creed, to which they had subscribed at Seleucia, they anathematized that which had been set forth at Ariminum by their former associates in opinion. They moreover again condemned the party of Acacius and Eudoxius, and declared their deposition to have been just. The civil war which was then impending prevented Eudoxius bishop of Constantinople from either gainsaying or revenging these determinations. Wherefore Eleusius bishop of Cyzicus and his adherents became for a little while the stronger party; inasmuch as they supported the views of Macedonius, which although before but obscurely known, acquired great publicity through the Synod at Lampsacus. This Synod, I think, was the cause of the increase of the Macedonians in the Hellespont; for Lampsacus is situated in one of the narrow bays of the Hellespont. Such was the issue of this council.
