James 4:11-12

11Believers, do not speak against or slander one another. He who speaks [self-righteously] against a brother or judges his brother [hypocritically], speaks against the Law and judges the Law. If you judge the Law, you are not a doer of the Law but a judge of it.

12There is only one Lawgiver and Judge, the One who is able to save and to destroy [the one God who has the absolute power of life and death]; but who are you to [hypocritically or self-righteously] pass judgment on your neighbor?
