Romans 14:1, 4, 12, 22

Be willing to accept those who still have doubts about what believers can do. And don’t argue with them about their different ideas.

You cannot judge the servants of someone else. Their own master decides if they are doing right or wrong. And the Lord’s servants will be right, because the Lord is able to make them right.

So each of us will have to explain to God about the things we do.

You should keep your beliefs about these things a secret between yourself and God. It is a blessing to be able to do what you think is right without feeling guilty.
