Dei Verbum says, "Sacred tradition and Sacred Scripture form one sacred deposit of the word of God, committed to the Church". Note that it is not Sacred Scripture alone that makes the word of God but rather combined with the Sacred Tradition it makes it so. This needs serious reflection.This Catechism of the Catholic Church is precisely where both the Sacred Tradition and Sacred Scripture meets! As a sample, just reading about incarnation, CCC 471-474 blows me away. Pure Masterpiece! It can only come from the ones chosen by Christ himself.
