HOLY TRADITION – the doctrine of the faith, the law of God, the sacraments, and the ritual as handed down by the true believers and worshipers of God by word and example from one to another, and from generation to generation.
All true believers united by the holy tradition of the faith, collectively and successively, by the will of God, compose the Church; and she is the sure repository of holy tradition, or, as St. Paul expresses it, The Church of the living God, the pillar and ground of the truth. 1 Tim. iii. 15.
St. Irenæus writes: We ought not to seek among others the truth, which we may have for asking from the Church; for in her, as in a rich treasure-house, the Apostles have laid up in its fullness all that pertains to the truth, so that whosoever seeketh may receive from her the food of life. She is the door of life. (Adv. Hæres. lib. iii. c. 4.)
