Matthew 7:1-5
"Do not pass [condemning] judgment [on other people] so that you do not receive such judgment [on yourselves].
Romans 2:1-2
So, whoever you are, you people do not have any excuse for judging people [Note: At this point Paul begins addressing the Jews. See verse 17]. For in a matter where you judge someone else [to be wrong] you [actually] condemn yourselves, because you are practicing the same things [you condemn them for doing].
Romans 14:22
Therefore, whatever you believe about this matter should be held between you and God. That person is happy who does not condemn himself for practicing something he believes is right.
