Romans 14:2-3

Amplified Bible

² One man’s faith permits him to eat everything, while the weak believer eats only vegetables [to avoid eating ritually unclean meat or something previously considered unclean]. ³ The one who eats [everything] is not to look down on the one who does not eat, and the one who does not eat must not criticize or pass judgment on the one who eats [everything], for God has accepted him.
