He expounds the passage of the Gospel, The Father judges no man, and further speaks of the assumption of man with body and soulwrought by the Lord, of the transgression of Adam, and of death and the resurrection of the dead
Before passing on, however, to what follows, I will further mention the one text, “Destroy this temple, and in three days I will raise it up.” Just as we, through soul and body, become a temple of Him Who “dwells in us and walks in us,” even so the Lord terms their combination a “temple,” of which the “destruction” signifies the dissolution of the soul from the body. And if they allege the passage in the Gospel, “The Word was made flesh,” in order to make out that the flesh was taken into the Godhead without the soul, on the ground that the soul is not expressly mentioned along with the flesh, let them learn that it is customary for Holy Scripture to imply the whole by the part.
For He that said, “Unto You shall all flesh come,” does not mean that the flesh will be presented before the Judge apart from the souls: and when we read in sacred History that Jacob went down into Egypt with seventy-five souls we understand the flesh also to be intended together with the souls. So, then, the Word, when He became flesh, took with the flesh the whole of human nature; and hence it was possible that hunger and thirst, fear and dread, desire and sleep, tears and trouble of spirit, and all such things, were in Him. For the Godhead, in its proper nature, admits no such affections, nor is the flesh by itself involved in them, if the soul is not affected co-ordinately with the body.
