John Chrysostom

He does not say, "ye are not minded," but, "ye will not be minded;" that is, you will be set right. And how does he know this? he says not "I know," but "I trust in God, and invoking His aid in order to your correction, I am in hopes;" and he says, not merely, "I have confidence in the Lord," but, "I have confidence towards you in the Lord." Every where he connects complaint with his praises; here it is as if he had said, I know my disciples, I know your readiness to be set right. I have good hopes, partly because of the Lord who suffers nothing, however trivial, to perish, partly because of you who are quickly to recover yourselves. At the same time he exhorts them to use diligence on their own parts, it not being possible to obtain aid from God, if our own efforts are not contributed.

Not only by words of encouragement, but by uttering a curse or a prophecy against their teachers, he applies to them an incentive. And observe that he never mentions the name of these plotters, that they might not become more shameless. His meaning is as follows. Not because "ye will be none otherwise minded," are the authors of your seduction relieved from punishment. They shall be punished; for it is not proper that the good conduct of the one should become an encouragement to the evil disposition of the other. This is said that they might not make a second attempt upon others. And he says not merely, "he that troubleth," but, "whosoever he be," in the way of aggravation.
