Canon IV
Concerning Maximus the Cynic and the disorder which has happened in Constantinople on his account, it is decreed that Maximus never was and is not now a Bishop; that those who have been ordained by him are in no order whatever of the clergy; since all which has been done concerning him or by him, is declared to be invalid.
