Romans 14:2; Romans 14:21; Romans 14:23

2 For one believeth that he may eat all things: another, who is weak, eateth herbs.

21 It is good neither to eat flesh, nor to drink wine, nor any thing whereby thy brother stumbleth, or is offended, or is made weak.

23 And he that doubteth is damned if he eat, because he eateth not of faith: for whatsoever is not of faith is sin.
