Sacred tradition

In the Catholic Church and in some other religious bodies, Sacred Tradition is held as one infallible, inerrant source for teaching and doctrine on matters related to faith and morals. (The Bible is another, the Church's Magisterium, or teaching authority, is the third.) It is held that God has guided the history of the church, the formation of certain practices, and certain decisions of Popes and ecumenical councils, in order to form the basis of many doctrines and practices in the Catholic Church.
