Romans 14:20-23

20Do not destroy the work of God for the sake of food. For although all things are clean, it is wrong to cause anyone to stumble by what you eat.

21It is good not to eat meat or drink wine or to do anything that causes your brother to stumble.

22The faith you have, keep to yourself before God. Blessed is the one who does not judge himself by what he approves.

23But the man who doubts is condemned if he eats, because he does not do so from faith, and whatever is not from faith is sin.
