Catechism of the Catholic Church §13 — excerpt
The plan of this catechism is inspired by the great tradition of catechisms which build catechesis on four pillars: the baptismal profession of faith (the Creed), the sacraments of faith, the life of faith (the Commandments), and the prayer of the believer (the Lord's Prayer).
