John Chrysostom
Here, as I noted above, the Apostle proves not only the equal honor of Jew and Gentile, but also that the Jew is more heavily burdened because the law was given to him.
The Gentile is condemned without law. But this phrase, "without having the law," indicates here not greater severity, but greater leniency. It means that the Gentile does not have the law as his accuser.
"Without having the law" means outside condemnation according to the law. The Apostle says this means that the Gentile is judged only by natural reason.
But the Jew is judged by the law. That is, together with nature, the law also exposes him. Since he enjoyed greater care, he will be subject to greater punishment.

If they must be subject to greater punishment, they need grace more than the Greeks.
