Augustine of Hippo

(Tract. xxvii. s. 5) Or thus, the flesh profiteth nothing. They had understood by His flesh, as it were, of a carcase, that was to be cut up, and sold in the shambles, not of a body animated by the spirit. Join the spirit to the flesh, and it profiteth much: for if the flesh profited not, the Word would not have become flesh, and dwelt among us. The Spirit hath done much for our salvation, by means of the flesh.
