Baltimore Catechism Number 4 (Paperback) (ISBN-13: 9798792626614)

This is also known as An Explanation of the Baltimore Catechism of Christian Doctrine for the Use of Sunday-School Teachers and Advanced Classes. These have been restored to their original format. Another publisher has changed the fast regulations to those put in place after Vatican II. We have added the fast regulations in place at the time of Pope Pius XII's death. The Catechism forms a part of the ordinary magisterium (teaching authority of the Church).
