Romans 14:21-23

21It is better not to eat meat or drink wine or do anything else if it might cause another believer to stumble.

22You may believe there’s nothing wrong with what you are doing, but keep it between yourself and God. Blessed are those who don’t feel guilty for doing something they have decided is right.

23But if you have doubts about whether or not you should eat something, you are sinning if you go ahead and do it. For you are not following your convictions. If you do anything you believe is not right, you are sinning.
