James 4:11-12 CEB

11 Brothers and sisters, don't say evil things about each other. Whoever insults or criticizes a brother or sister insults and criticizes the Law. If you find fault with the Law, you are not a doer of the Law but a judge over it.
12 There is only one lawgiver and judge, and he is able to save and to destroy. But you who judge your neighbor, who are you?
