Canon 80
About the impermissibility of appointing a newly baptized person or someone who has recently left a vicious lifestyle as a bishop.
Anyone who has converted from pagan life and has been baptized or abandoned an evil lifestyle should not be immediately appointed a bishop. For there is no justice in having someone who has not yet been tested become a teacher of others, unless this is arranged by God’s grace.
Greek original
Τὸν ἐξ ἐθνικοῦ βίου προσελθόντα, καὶ βαπτισθέντα, ἢ ἐκ φαύλης διαγωγῆς, οὐ δίκαιόν ἐστι πάραυτα προχειρίζεσθαι ἐπίσκοπον· ἄδικον γάρ, τὸν μηδέπω πεῖραν ἐπιδειξάμενον, ἑτέρων εἶναι διδάσκαλον· εἰμή που κατὰ θείαν χάριν τοῦτο γένηται.
