How can a Catholic recognize what is "of the Faith" and what is a deviation from right doctrine?
 
Readers will be pleased to find here a brief, clear exposition of the Church's constant awareness that mankind does not determine the Faith, but only professeses it - or fails to do so.
 
This is the essential nature of Sacred Tradition, and Fr. Ripperger here offers a helpful outline of both the object and nature of Tradition, as well as the moral requirement of Catholics to accept it, the role played by individual conscience in so doing, and the various sins by which one fails in regard to it.
