Jesus commanded his disciples not to judge.Judge not, that ye be not judged. Matthew 7:1And Paul seemed to agree with Jesus on that. (In his epistle to the Romans, anyway.)
Judge not, and ye shall not be judged. Luke 6:37Therefore thou art inexcusable, O man, whosoever thou art that judgest: for wherein thou judgest another, thou condemnest thyself; for thou that judgest doest the same things. Romans 2:1As did the author of James.
But why dost thou judge thy brother? or why dost thou set at nought thy brother? for we shall all stand before the judgment seat of Christ. Romans 14:10Who art thou that judgest another? James 4:12
Leviticus says that righteous people should judge others.In righteousness shalt thou judge thy neighbour. Leviticus 19:15In the gospel of John, Jesus said that we should "judge righteous judgment."Judge not according to the appearance, but judge righteous judgment. John 7:24And Paul said that spiritual people should judge "all things" in this life and will judge angels in the next.But he that is spiritual judgeth all things, yet he himself is judged of no man. 1 Corinthians 2:15
For what have I to do to judge them also that are without? do not ye judge them that are within? But them that are without God judgeth. Therefore put away from among yourselves that wicked person. 1 Corinthians 5:12-13
Do ye not know that the saints shall judge the world? and if the world shall be judged by you, are ye unworthy to judge the smallest matters? Know ye not that we shall judge angels? how much more things that pertain to this life?. 1 Corinthians 6:2-3
