For you were once darkness, but now are you light in the Lord: walk as children of light:
All Commentaries on Ephesians 5:8 Go To Ephesians 5
Jerome
AD 420
The darkness is being turned into light. There is not, as some heretics argue, a nature so alienated that it cannot receive salvation…. Those who receive salvation—the righteous—are “the light of the world.” Those who refuse, the unrighteous, are in consequence called darkness…. The difference and distance between one and the other is clearly seen by their own fruits. .
