CATECHISM
BASIC R.C. BELIEF A book containing a summary of the principles of religion. The classic catechism was in question and answer form, and covered four basic areas: the Creed, the Sacraments, the Decalogue and the Lord’s Prayer.
From CATHOLIC DICTIONARY OF THEOLOGY, Vol II,, page 1. “Catechisms in general are said to be safe in their doctrine, but are not accounted to be infallible or entirely free from error. The Catechism of the Council of Trent stated that the Apostles’ Creed was made by the Apostles themselves, and also made it clear that the first end of marriage was not procreation.”
POST VATICAN II Recent catechisms have been in prose form, with ecumenical overtures.
