Chapter 1 — Preface to the Roman Catechism
Section 24. The part on the Creed contains all that is to be held according to Christian faith, whether it regard the knowledge of God, the creation and government of the world, or the redemption of man, the rewards of the good and the punishments of the wicked. The part devoted to the Seven Sacraments teaches us what are the signs, and, as it were, the instruments of grace. In the part on the Decalogue is described whatever has reference to the law, whose end is charity. Finally, the Lord's Prayer contains whatever can be the object of the Christian's desires, or hopes, or prayers. The exposition, therefore, of these four parts, which are, as it were, the general heads of Sacred Scripture, includes almost everything that a Christian should learn.
