Canon 25
The need for proteges to the rank of clerics to first study the resolutions of the Councils.
It was convenient: when ordaining a bishop or clergyman, let those ordaining them first let them listen to the decisions of the Councils, so that, acting according to the decisions of the Council, they would not repent.
Greek original
Ὁμοίως ἤρεσεν, ὥστε, χειροτονουμένου ἐπισκόπου, ἢ κληρικοῦ, πρότερον ἀπὸ τῶν χειροτονούντων αὐτοὺς τὰ δεδογμένα ταῖς συνόδοις εἰς τὰς ἀκοὰς αὐτῶν ἐντίθεσθαι, ἵνα μὴ ποιοῦντες κατὰ τῶν ὅρων τῆς συνόδου μεταμεληθῶσιν.[1]
