Do not, for the sake of food, destroy the work of God. Everything is, indeed, clean, but it is wrong for anyone to make another stumble by what he eats. It is good not to eat meat or drink wine or do anything that causes your brother to stumble. The faith that you have, keep between yourself and God. Blessed is the one who has no reason to pass judgment on himself for what he approves. But whoever has doubts is condemned if he eats because the eating is not from faith. For whatever does not proceed from faith is sin. (Romans 14.20-23)
