Romans 14:20-23

20Do not destroy the work of God for the sake of food. All things indeed are pure, but it is evil for the man who eats with offense.

21It is good neither to eat meat nor drink wine nor do anything by which your brother stumbles or is offended or is made weak.

22Do you have faith? Have it to yourself before God. Happy is he who does not condemn himself in what he approves.

23But he who doubts is condemned if he eats, because he does not eat from faith; for whatever is not from faith is sin.
