Romans 14:5-7

New Revised Standard Version, Anglicised 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 honour of the Lord. Also those who eat, eat in honour of the Lord, since they give thanks to God; while those who abstain, abstain in honour of the Lord and give thanks to God.

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