If a bishop or presbyter baptize anew anyone that has had a true baptism, or fail to baptize someone that had been polluted by the impious, let him be defrocked, on the grounds that he is mocking the cross and death of the Lord, and fails to distinguish priests from false priests.
Apostolic Canon L (50)
We order that a bishop or presbyter that recognized the baptism or sacrifice of heretics be defrocked. For "what accord has Christ with Belial? Or what has a believer in common with an unbeliever?" (2 Cor. 6:15).
Apostolic Canon XLVII (47)
