Romans 14:19-23

So then we pursue the things which make for peace and the building up of one another. Do not tear down the work of God for the sake of food. All things indeed are clean, but they are evil for the man who eats and gives offense. It is good not to eat meat or to drink wine, or to do anything by which your brother stumbles. The faith which you have, have as your own conviction before God. Happy is he who does not condemn himself in what he approves. But he who doubts is condemned if he eats, because his eating is not from faith; and whatever is not from faith is sin.
