Canon 53
About the eruption of clergy who do not eat wine and meat, not for the sake of the feat of abstinence.
If a bishop, presbyter or deacon does not eat meat and wine on holidays, disdaining them, and not for the sake of achievement, let him be cast out as one who is burned in his conscience and has become the cause of temptation for many.
Greek original
Εἴ τις ἐπίσκοπος, ἢ πρεσβύτερος, ἢ διάκονος, ἐν ταῖς ἡμέραις τῶν ἑορτῶν οὐ μεταλαμβάνει κρεῶν, καὶ οἴνου, βδελυσσόμενος καὶ οὐ δι᾿ ἄσκησιν, καθαιρείσθω, ὡς κεκαυτηριασμένος τὴν ἰδίαν συνείδησιν, καὶ αἴτιος σκανδάλου πολλοῖς γινόμενος.
