John Chrysostom
AD 407
Here too Paul shows that the heathen were responsible for their own sins, and he deprives them of all excuse. For he says that their evil deeds did not come from ignorance but from willful practice. This is why he did not say “because they did not know God,” but rather “they did not see fit to acknowledge God.” In other words, their sin was one of a perverted determination of obstinacy more than of a sudden ravishment, and it was not in the flesh (as some heretics say) but in the mind, to whose wicked lust the sins belonged and from which the fount of evils flowed. For if the mind becomes undiscerning, everything else is dragged off course and overturned.
