Anyone who is somewhat familiar with Jesus’ teachings knows that He told us not to judge. But the differences of opinion over what He meant by this, as well as the actions of many Christians, reveal that a lot of people are apparently confused about this subject. Did Jesus intend that we never judge anyone on any matter? Was His aim that we not judge our brethren but that we have an obligation to show the world its sins? Did He mean that we should judge moral infractions but not be critical about doctrine? Or did He want us to be discerning over doctrine but soft on morality? In this article, I intend to show from the Bible when/what/who we are to judge and when/what/who we are not to judge. Also, I’ll point out the harm of judging when we are not supposed to.
