Catechism of the Catholic Church

This living transmission, accomplished in the Holy Spirit, is called Tradition, since it is distinct from Sacred Scripture, though closely connected to it. Through Tradition, "the Church, in her doctrine, life, and worship perpetuates and transmits to every generation all that she herself is, all that she believes." "The sayings of the holy Fathers are a witness to the life-giving presence of this Tradition, showing how its riches are poured out in the practice and life of the Church, in her belief and her prayer." (174, 1124, 2651)
