The Canons of the 217 Blessed Fathers who assembled at Carthage 62

Of condemned clerics.

And this should be sought, that they deign to decree that if any clergyman of whatever rank shall have been condemned by the judgment of the bishops for any crime, he may not be defended either by the churches over which he presided, nor by anyone whatever, under pain of loss both of money and office, and let them order that neither age nor sex be received as an excuse.

Notes.

Ancient Epitome of Canon LXII.

No one shall justify a clergyman condemned by his own bishop.

This is Canon vj. of the Synod of Carthage, June 15 (or 16), a.d. 401.
