Tertullian

“ In fact, since the transgression which caused man’s ruin was committed quite as much by the instigation of the soul from concupiscence as by the action of the flesh from actual fruition, it has marked the entire man with the sentence of transgression, and has therefore made him deservedly amenable to perdition. ”

“ Man, of course, in his texture of flesh and soul. Neither, therefore, of those parts which He has received will He allow to perish; nay, no considerable portion—nay, not the least fraction, of either. If the flesh be, as our opponents slightingly think, but a poor fraction, then the flesh is safe, because not a fraction of man is to perish; and no larger portion is in danger, because every portion of man is in equally safe keeping with Him. ”

“ Then must the devil be understood to be stronger for injuring man, ruining him wholly? and must God have the character of comparative weakness, since He does not relieve and help man in his entire state? The apostle, however, suggests that “where sin abounded, there has grace much more abounded.” [2] How, in fact, can he be regarded as saved, who can at the same time be said to be lost—lost, that is, in the flesh, but saved as to his soul? ”
