Fourth Council of Constantinople : 869-870

650 Can. 1. If we wish to proceed without offence along the true and royal road of divine justice, we must keep the declarations and teachings of the holy fathers as if they were so many lamps which are always alight and illuminating our steps which are directed towards God.

651 Therefore, considering and esteeming these as a second word of God, in accordance with the great and most wise Denis, let us sing most willingly along with the divinely inspired David, The commandment of the Lord is bright, enlightening the eyes, and, Your word is a lamp to my feet and a light to my paths; and with the author of Proverbs we say, Your commandment is a lamp and your law a light, and like Isaiah we cry to the lord God with loud voice, because your commands are a light for the earth. For the exhortations and warnings of the divine canons are rightly likened to light inasmuch as the better is distinguished from the worse and what is advantageous and useful is distinguished from what is not helpful but harmful.

652 Therefore we declare that we are preserving and maintaining the canons which have been entrusted to the holy, catholic and apostolic church by the holy and renowned apostles, and by universal as well as local councils of orthodox [bishops], and even by any inspired father or teacher of the church. Consequently, we rule our own life and conduct by these canons and we decree that all those who have the rank of priests and all those who are described by the name of Christian are, by ecclesiastical law, included under the penalties and condemnations as well as, on the other hand, the absolutions and acquittals which have been imposed and defined by them. For Paul, the great apostle, openly urges us (cf. 2 Thess 2, 14) to preserve the traditions which we have received, either by word or by letter, of the saints who were famous in times past.
