Romans 14:5-7

New Revised Standard Version Catholic Edition

⁵ Some judge one day to be better than another, while others judge all days to be alike. Let all be fully convinced in their own minds. ⁶ Those who observe the day, observe it in honor of the Lord. Also those who eat, eat in honor of the Lord, since they give thanks to God; while those who abstain, abstain in honor of the Lord and give thanks to God.

⁷ We do not live to ourselves, and we do not die to ourselves.
