These are they who separate themselves, sensual, having not the Spirit.
All Commentaries on Jude 1:19 Go To Jude 1
Clement Of Alexandria
AD 215
Those, he says, separating the faithful from the unfaithful, be convicted according to their own unbelief. And again those separating from the flesh. He says, Animal not having the spirit; that is, the spirit which is by faith, which supervenes through the practice of righteousness.
