Among whom also we all had our behavior in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
All Commentaries on Ephesians 2:3 Go To Ephesians 2
Jerome
AD 420
There is a difference between sin of the flesh and sin of the mind. The sin of the flesh is indecency and profligacy and whatever might act as instrument to its lusts. The transgression of the mind pertains to doctrine contrary to truth and to the baseness of heretics. .
