Romans 14:1, 4, 12, 22

Accept into your group someone who is weak in faith, and do not argue about opinions.

You cannot judge another person’s servant. The master decides if the servant 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.

Your beliefs about these things should be kept secret between you and God. People are happy if they can do what they think is right without feeling guilty.
