The Canons of the Councils of Ancyra, Gangra, Neocæsarea, Antioch and Laodicea, which Canons were Accepted and Received by the Ecumenical Synods 66Canon III.

If any presbyter or deacon, or any one whatever belonging to the priesthood, shall forsake his own parish, and shall depart, and, having wholly changed his residence, shall set himself to remain for a long time in another parish, let him no longer officiate; especially if his own bishop shall summon and urge him to return to his own parish and he shall disobey. And if he persist in his disorder, let him be wholly deposed from his ministry, so that no further room be left for his restoration. And if another bishop shall receive a man deposed for this cause, let him be punished by the Common Synod as one who nullifies the ecclesiastical laws.
