Sinodos: The Apostolic Canons 6

1But if a bishop or one of the priests who does not accept the eucharist at the time of the solemnization, mentions a reason for this ; and if there is something that made him unworthy, let him be forgiven : but if he does not mention a reason, let him be deposed ; for he was the leader that there should be sin to the people, and has caused them to take offence at him who has brought the eucharist, as though he had not brought it in purity.
