Theophylact of Ohrid, on Jas 4:12

“There is one lawgiver, and judge, that is able to destroy and to deliver.”

“Therefore, do not presume, he says, to degrade and, as it were, to counter-legislate, for this will not be forgiven you, since there is only one Lawgiver — God, who is able "to save and to destroy" transgressors of His law, for to punish the transgressors of the law belongs to the law and the Lawgiver, while you have nothing more than idle talk and yourself bring upon yourself the sentence of condemnation, for doing the same thing as the one you condemn, you condemn yourself to the same degree that you condemn him. He speaks dismissively. When you yourself are such, how dare you judge one of like nature?”
