Catholic doctrine regarding the Ten Commandments

The Ten Commandments are a series of religious and moral imperatives that are recognized as a moral foundation in several of the Abrahamic religions, including Catholicism. As described in the Old Testament books Exodus and Deuteronomy, the Commandments form part of a covenant offered by God to the Israelites to free them from the spiritual slavery of sin. According to the Catechism of the Catholic Church—the official exposition of the Catholic Church's Christian beliefs—the Commandments are considered essential for spiritual good health and growth, and serve as the basis for Catholic social justice. A review of the Commandments is one of the most common types of examination of conscience used by Catholics before receiving the sacrament of Penance.

The Commandments appear in the earliest Church writings; the Catechism states that they have "occupied a predominant place" in teaching the faith since the time of Augustine of Hippo (AD 354–430). The Church had no official standards for religious instruction until the Fourth Lateran Council in 1215; evidence suggests the Commandments were used in Christian education in the early Church and throughout the Middle Ages, but with inconsistent emphasis. The lack of instruction in them by some dioceses formed the basis of one of the criticisms launched against the Church by Protestant reformers. Afterward, the first Church-wide catechism in 1566 provided "thorough discussions of each commandment", but gave greater emphasis to the seven sacraments. The most recent Catechism devotes a large section to interpret each of the commandments.
