John Chrysostom

"For we are sure that the judgment of God is according to truth against them who commit such things." For lest any should say, until now I have escaped, to make him afraid, he says, that it is not so with God as it is here. For here one is punished, and another escapes while doing the same thing. But hereafter it is not so. That he that judgeth then knoweth the right, he has said: but whence he knoweth it, he hath not added; for it was superfluous. For in the case of ungodliness, he shows both that the ungodly was so even with a knowledge of God, and also whence he got that knowledge, namely, from the Creation. For inasmuch as it was not plain to all, he gave the cause also; but here he passes it over as a thing admitted. But when he says, "whosoever thou art that judgest," he is not addressing himself to the rulers only, but to private individuals and subjects also. For all men, even if they have no chair of state, nor executioners, nor stocks at command, yet even they judge those that offend, in conversations and public meetings and by the vote of their conscience. And no one would venture to say, that the adulterer does not deserve punishment. But it is others, he says, they condemn, and not themselves. And for this cause he stands forth vehemently against them.
