Romans 5:13

So much we can see; so much is simple matter of history, that sin was in the world from Adam downwards. But here comes the difficulty. Sin there was, but why guilt? And why death, the punishment of guilt? The pre-Mosaic man sinned indeed, but could not rightly be condemned for his sin until there was a law to tell him plainly the distinction between right and wrong.

It will be observed that the law of nature (Romans 1:19; Romans 2:14) is here left out of consideration. In the places mentioned, St. Paul speaks of the law of nature only as applicable to his contemporaries or to comparatively recent times. He does not throw back its operation into the primitive ages of the world; neither does he pronounce upon the degree of responsibility which men, as moral agents, then incurred. This would fall in with the doctrine that the consciousness of right and wrong was gradually formed. It is not, indeed, to be said that St. Paul exactly anticipated the teachings of the inductive school of moralists, but there is much in their system, or at any rate in the results to which they seem to be coming, that appears to fall into easy and harmonious relations with the teaching of the Apostle.
