Tertullian

“ For to blow or breathe is to respire. So that we are driven to describe, by (the term which indicates this respiration—that is to say) spirit—the soul which we hold to be, by the propriety of its action, breath. Moreover, we properly and especially insist on calling it breath (or spirit) , in opposition to Hermogenes, who derives the soul from matter instead of from the afflatus or breath of God. ”

“ Scripture, which has a better knowledge of the soul’s Maker, or rather God, has told us nothing more than that God breathed on man’s face the breath of life, and that man became a living soul, by means of which he was both to live and breathe; at the same time making a sufficiently clear distinction between the spirit and the soul, [3] in such passages as the following, wherein God Himself declares: “My Spirit went forth from me, and I made the breath of each. And the breath of my Spirit became soul.” ”

“ Consequently, as the spirit neither of God nor of the devil is naturally planted with a man’s soul at his birth, this soul must evidently exist apart and alone, previous to the accession to it of either spirit: if thus apart and alone, it must also be simple and uncompounded as regards its substance ”
