Romans 14:3-5

New Catholic Bible

³ The one who eats everything must not look contemptuously on the one who does not, and the one who abstains must not pass judgment on the one who eats, for God has welcomed both. ⁴ What right do you have to pass judgment on someone else’s servant? The master will determine whether that servant will stand or fall. But the servant will be upheld, for the Lord has the power to enable him to stand.

⁵ One person may consider one day to be more sacred than another, while another may judge all days to be alike. Let everyone be convinced in his own beliefs.
