Romans 14:20-23

20Do not destroy the work of God for the sake of food. All food is clean, but it is wrong for a man to let his eating be a stumbling block. 21It is better not to eat meat or drink wine or to do anything to cause your brother to stumble.1

22Keep your belief about such matters between yourself and God.2 Blessed is the one who does not condemn himself by what he approves. 23But the one who has doubts is condemned if he eats, because his eating is not from faith; and everything that is not from faith is sin.3
