Romans (Rom) 14:1, 4, 12, 22

Now as for a person whose trust is weak, welcome him — but not to get into arguments over opinions.

who are you to pass judgment on someone else’s servant? It is before his own master that he will stand or fall; and the fact is that he will stand, because the Lord is able to make him stand.

So then, every one of us will have to give an account of himself to God.

The belief you hold about such things, keep between yourself and God. Happy the person who is free of self-condemnation when he approves of something!
