Правило 79
That a person possessed by a demon is not accepted into the clergy and is not allowed to pray with the faithful.
If anyone is possessed by a demon, he should not become a cleric, and even with the faithful he should not pray. After purification, let him be admitted to prayer with the faithful and, if he proves worthy, let him become a cleric.
Greek original
Ἐάν τις δαίμονα ἔχῃ, κληρικὸς μὴ γινέσθω, ἀλλὰ μηδὲ τοῖς πιστοῖς συνευχέσθω· καθαρισθεὶς δέ, προσδεχέσθω, καί, ἐὰν ᾖ ἄξιος, γινέσθω.
