CATECHISM OF THE CATHOLIC CHURCH
SECOND EDITION

Paragraphs 2166–2169

2166 The Christian begins his prayers and activities with the Sign of the Cross: "in the name of the Father and of the Son and of the Holy Spirit. Amen."
2167 God calls each one by name (cf. Isa 43:1).
Remember the sabbath day, to keep it holy. Six days you shall labor, and do all your work; but the seventh day is a sabbath to the Lord your God; in it you shall not do any work.

The sabbath was made for man, not man for the sabbath; so the Son of Man is lord even of the sabbath.

2168 The third commandment of the Decalogue recalls the holiness of the sabbath: "The seventh day is a sabbath of solemn rest, holy to the LORD."

2169 In speaking of the sabbath Scripture recalls creation: "For in six days the LORD made heaven and earth, the sea, and all that is in them, and rested the seventh day; therefore the Lord blessed the sabbath day and hallowed it."
