Also known as the Roman Catechism and the Catechism of Pius V, this authoritative Catechism of the Catholic faith was commissioned by the Council of Trent and compiled under the direction of St. Charles Borromeo. Published at the command of Pope Pius V in 1566, it remained the official manual of popular instruction for the Catholic Church for over 400 years, until the promulgation of the new Catechism of the Catholic Church.
