John Chrysostom

"For when the Gentiles," he says, "which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves." I am not, he means, rejecting the Law, but even on this score I justify the Gentiles. You see how when undermining the conceit of Judaism, he giveth no handle against himself as villifying the Law, but on the contrary by extolling it and showing its greatness he so makes good his whole position. But whenever he saith "by nature," he means by the reasonings of nature. And he shows that others are better than they, and, what is more better for this, that they have not received the Law, and have not that wherein the Jews seem to have an advantage over them. For on this ground he means they are to be admired, because they required not a law, and yet exhibited all the doings of the Law, having the works, not the letters, graven upon their minds.
