Speak not against each other, brothers. He who speaks against a brother and judges his brother, speaks against law and judges law. But if thou judge law, thou are not a doer of law, but a judge.

But brother goes to law against brother, and this before unbelievers?

And when the men heard, they glorified God, having said to him, Thou see, brother, how many thousands there are of the Jews who have believed, and they are all zealots of the law.
