My LORD’s BibleSinodos: The Apostolic Canons 12
1But if any presbyter or deacon or any one of the grade of priests leaves his post and goes to another place and dwells at that place a length of time, except by permission of the bishop, we order that he forever do not perform his official functions. And especially, if the bishop has sent to him to return to his place, and he has not listened to him, let him be expelled from his office, and let him approach the place where he was as a layman. And if the bishop with whom he was receives him as one of the priests, and regards this order which we have established as void, let this bishop also be expelled as a teacher of the transgression of the law.
