CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 2062–2066

2062 The Commandments properly so-called come in the second place: they express the implications of belonging to God through the establishment of the covenant. Moral existence is a response to the Lord's loving initiative. It is the acknowledgement and homage given to God and a worship of thanksgiving. It is cooperation with the plan God pursues in history.
2063 The covenant and dialogue between God and man are also attested to by the fact that all the obligations are stated in the first person ("I am the Lord.") and addressed by God to another personal subject ("you"). In all God's commandments, the singular personal pronoun designates the recipient. God makes his will known to each person in particular, at the same time as he makes it known to the whole people:

The Lord prescribed love towards God and taught justice towards neighbor, so that man would be neither unjust, nor unworthy of God. Thus, through the Decalogue, God prepared man to become his friend and to live in harmony with his neighbor. . . . The words of the Decalogue remain likewise for us Christians. Far from being abolished, they have received amplification and development from the fact of the coming of the Lord in the flesh.

2064 In fidelity to Scripture and in conformity with the example of Jesus, the tradition of the Church has acknowledged the primordial importance and significance of the Decalogue.
2065 Ever since St. Augustine, the Ten Commandments have occupied a predominant place in the catechesis of baptismal candidates and the faithful. In the fifteenth century, the custom arose of expressing the commandments of the Decalogue in rhymed formulae, easy to memorize and in positive form. They are still in use today. The catechisms of the Church have often expounded Christian morality by following the order of the Ten Commandments.
2066 The division and numbering of the Commandments have varied in the course of history. The present catechism follows the division of the Commandments established by St. Augustine, which has become traditional in the Catholic Church. It is also that of the Lutheran confessions. The Greek Fathers worked out a slightly different division, which is found in the Orthodox Churches and Reformed communities.
