Правило 78
That a deaf or blind person cannot be a bishop.
Let a deaf and blind person not become a bishop - not because he is allegedly defiled, but so that there is no obstacle to church affairs.
Greek original
Κωφὸς δὲ ὤν, καὶ τυφλός, μὴ γινέσθω ἐπίσκοπος· οὐχ ὡς μεμιασμένος, ἀλλ᾿ ἵνα μὴ τὰ ἐκκλησιαστικὰ παρεμποδίζοιτο.
