Of the COUNCIL of Sida in Pamphylia.
ST. Amphilochius assembled in 383, a Council of 25 Bishops at Sida, a City of Pamphylia, against * 1.1 the Heresy of the Massalians or the Euchaitae. This Council condemned the Errors of these He∣reticks, and wrote a Synodical Letter to Flavianus Bishop of Antioch: It is not now extant. Photius had read it, and he tells us of it in Volume 52 of his Bibliotheca.
The same Photius speaks in this place of a Synod held against these Hereticks at Antioch by Flavianus. There were present in it Three Bishops and 30 Priests and Deacons of the Church of Antioch. There Adelphius a Ring-leader of the Heresy of the Massalians was condemned, and they would not receive him tho' he should have abjur'd his Heresy, because they were persuaded that he would not do it sin∣cerely, these Hereticks making no scruple of renouncing their Doctrine with their mouth. Flavianus sent an account to the Osroënians of what pass'd in this Synod.
