Romans 2:1-3 NIV

(1)You, therefore, have no excuse, you who pass judgment on someone else, for at whatever point you judge the other, you are condemning yourself, because you who pass judgment do the same things. (2) Now we know that God's judgment is based on truth. (3) So when you, a mere man, pass judgment on them and yet do the same things, do you think you will escape God's judgment?


I take this as a warning against judging others.
