The Catechism of the Catholic Church is a summary of the truths of Christ as transmitted and taught by the Church He founded. The Catholic Catechism covers four major areas of our faith life: The Profession of Faith (Apostles Creed); The Celebration of the Christian Mystery (the Sacraments); Life in Christ; and Christian Prayer. Some of the Catholic catechisms from earlier times are the Catechism of the Council of Trent, and the Baltimore Catechism. There are also many books that provide in-depth explanations of what is contained in the official Catholic Catechism. You will even find catechisms for children and teens!
