But all things that are reproved are made manifest by the light: for whatsoever does make manifest is light.
All Commentaries on Ephesians 5:13 Go To Ephesians 5
Gaius Marius Victorinus
AD 400
Having instructed them also to counsel all those who are doing ill, he next shows what a great service this is. For admonition makes those sins manifest. It puts them in the light. For the one who admonishes shows how important is the behavior he illumines. In doing this he is in effect illuminating the evil to show its consequences. When the one who commits evil understands this, the shadows are dispelled and he enters the light. .
