John Chrysostom, on Rom 5:13

“For until the law sin was in the world; but sin was not imputed, when the law was not.”

“The phrase "till the Law" some think he used of the time before the giving of the Law-that of Abel, for instance, or of Noah, or of Abraham-till Moses was born. What was the sin in those days, at this rate? some say he means that in Paradise. For hitherto it was not done away, (he would say,) but the fruit of it was yet in vigor. For it had borne that death whereof all partake, which prevailed and lorded over us. Why then does he proceed, "But sin is not imputed when there is no law?" It was by way of objection from the Jews, say they who have spoken on our side, that he laid this position down and said, if there be no sin without the Law, how came death to consume all those before the Law? But to me it seems that the sense presently to be given has more to be said for it, and suits better with the Apostle's meaning. And what sense is this? In saying, that "till the Law sin was in the world," what he seems to me to mean is this, that after the Law was given the sin resulting from the transgression of it prevailed, and prevailed too so long as the Law existed. For sin, he says, can have no existence if there be no law. If then it was this sin, he means, from the transgression of the Law that brought forth death, how was it that all before the Law died? For if it is in sin that death hath its origin, but when there is no law, sin is not imputed, how came death to prevail? From whence it is clear, that it was not this sin, the transgression, that is, of the Law, but that of Adam's disobedience, which marred all things. Now what is the proof of this? The fact that even before the Law all died: for "death reigned" he says, "from Adam to Moses, even over them that had not sinned."”
