Council of Arminum

rimini. Constantius II in 359 summoned two parallel councils for the West and East, at Arminum and Seleucia.* The Homoiousion group led by Basil of Ancyra wished to gain universal episcopal support at a time when Constantius had expelled the extreme Anomoeans Aetius and Eunomius. Less radical Anomoeans* (also called Homoeans*) such as Valens of Mursa, having persuaded Hosius of Cordova and Constantius to recognize their position (357), suggested with success that Constantius should summon two councils, facilitating their attempt to outmaneuver Basil. The Homoeans had constructed a creed “dated on the 22 May,” indicating, according to Athanasius, its novelty. Bishops at the Council of Arminum rejected it at first in favor of the creed of Nicea. When their delegates announced the decision to Constantius, however, he induced them to accept the “Dated Creed,” which was formally ratified at Constantinople in 360.
