Romans 14:1, 4, 12, 22

Do not refuse to accept into your group someone who is weak in faith. And do not argue with him about opinions.

You cannot judge another man’s servant. His own master decides if he is doing well or not. And the Lord’s servant will do well because the Lord helps him do well.

So each of us will have to answer to God for what he has done.

Your beliefs about these things should be kept secret between you and God. A person is blessed if he can do what he thinks is right without feeling guilty.
