Romans 14:21-23

Consider it an act of love to refrain from eating meat or drinking wine or doing anything else that would cause a fellow believer to be offended or tempted to be weakened in his faith. Keep the convictions you have about these matters between yourself and God, and don’t impose them upon others. You’ll be happy when you don’t judge yourself in doing what your conscience approves. But the one who has misgivings feels miserable if he eats meat, because he doubts and doesn’t eat in faith. For anything we do that doesn’t spring from faith is, by definition, sinful.
