Remember, remember, remember this. It's a principle.
13 Therefore let us stop passing judgment on one another. Instead, make up your mind not to put any stumbling block or obstacle in the way of a brother or sister. 14 I am convinced, being fully persuaded in the Lord Jesus, that nothing is unclean in itself. But if anyone regards something as unclean, then for that person it is unclean.
Most Christians I've met don't know this chapter. Learn the whole chapter. Most Christians I talked to about this don't know what a stumbling block is either. Don't let them take what you enjoy away, okay? Enjoy what you enjoy, if God wants to get you away from it, trust him to do so.
A stumbling block is where you cause another Christian to do something you feel alright about, but they don't. Paul is saying not to drag them into something they are in conflict about. But for you, are allow what you don't see a faith issue with, and other people have different allowances and sensitivities. The "weak" should not judge the "strong", and the other way around, the "strong" should not judge the "weak". I put quotes because those are the words Paul uses to describe certain Christians.
The strong can do anything, it's not a faith issue. The weak don't want to do anything, they think God will judge them. Let everyone be convinced in their own mind!
