Romans 14:4-6

Revised Standard Version Catholic Edition

⁴ Who are you to pass judgment on the servant of another? It is before his own master that he stands or falls. And he will be upheld, for the Master is able to make him stand.

⁵ One man esteems one day as better than another, while another man esteems all days alike. Let every one be fully convinced in his own mind. ⁶ He who observes the day, observes it in honor of the Lord. He also who eats, eats in honor of the Lord, since he gives thanks to God; while he who abstains, abstains in honor of the Lord and gives thanks to God.
