Tertullian

“ For although the soul has a kind of body of a quality of its own, [27] just as the spirit has, yet as the soul and the body are distinctly named, the soul has its own peculiar appellation, not requiring the common designation of body. ”

“ And when he shall have failed to produce and give proof of any such criterion, we will then on our side bring out both the Spirit and the prophecies of the Creator, which utter predictions according to His will. Thus it will be clearly seen of what the apostle spoke, even of those things which were to happen in the church of his God; and as long as He endures, so long also does His Spirit work, and so long are His promises repeated. ”

“ This is left for “the flesh,” which having no proper name (in this passage) , necessarily makes use of the common designation. Indeed, I see no other substance in man, after spirit and soul, to which the term body can be applied except “the flesh.” ”
