Compiled under the direction of St. Charles Borromeo and recognized as the most authoritative Catholic catechism. Leo XIII recommended two books-- the Summa and this Catechism--for all seminarians! Pope Benedict 16th, as a Cardinal, called it the most important Catholic Catechism. Originally designed to supply parish priest with an official book of instruction, it has been used extensively by the laity as a steadying guide in our confused age. New typesetting and beautiful hardbound cover.
