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.
