Who show the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)
All Commentaries on Romans 2:15 Go To Romans 2
John Chrysostom
AD 407
Conscience and reason take the place of the law. By saying this, Paul showed that God made persons independent, giving them the freedom to choose virtue and avoid vice. Do not be surprised that he proves this point, not once or twice but several times. He had to do this in order to counter those who said: “Why did Christ delay his coming so long? Where was this great scheme of providence before Christ came?” … But even before the law was given the human race enjoyed the care of providence. Why does Paul insert the words accuse or perhaps excuse?If they have a written law and do what it says, how can their thoughts still accuse them? Paul is not speaking here of the righteous only but of all mankind. For then our thoughts do pass judgment, some excusing us and others accusing. And at that tribunal, one needs no other accuser.
