That you put off concerning the former way of life the old man, which is corrupt according to the deceitful lusts;
All Commentaries on Ephesians 4:22 Go To Ephesians 4
Tertullian of Carthage
AD 220
The apostle clearly identifies the old man. For he “put off the old man which belongs to your former manner of life,” not with respect to the decay of any substance. For he is telling us to put away not the flesh but those things that he has elsewhere shown to be oriented to the fleshly way of life, indicting not the body as such but its works.
