James 4:11-12 - Warning Against Judging One Another
11 Do not slander one another, brothers, [for] the person who speaks against his brother, or judges him, is [guilty of] speaking against the law [of God]. But when you judge the law, you are not obeying it but acting as its judge. 12 There is only One Lawgiver and Judge [i.e., God or Christ]. It is He who is able to save and destroy [people]. So, who [do you think] you are, judging your neighbor?
