2192 “Sunday . . . is to be observed as the foremost holy day of obligation in the universal Church” (CIC, can. 1246 § 1). “On Sundays and other holy days of obligation the faithful are bound to participate in the Mass” (CIC, can. 1247).
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.”
Also one of the precepts of the Church specify attending Mass and Holy Day’s of Obligation.
