Augustine of Hippo

(in Joan. Tr. ii. c. 16) Or thus; in that the Word was made flesh and dwelt among us, His birth became a kind of ointment to anoint the eyes of our heart, that we might through His humanity discern His majesty; and therefore it follows, And we saw His glory. No one could see His glory, who was not healed by the humility of the flesh. For there had flown upon man’s eye as it were dust from the earth: the eye had been diseased, and earth was sent to heal it again; the flesh had blinded thee, the flesh restores thee. The soul by consenting to carnal affections had become carnal; hence the eye of the mind had been blinded: then the physician made for thee ointment. He came in such wise, as that by the flesh He destroyed the corruption of the flesh. And thus the Word was made flesh, that thou mightest be able to say, We saw His glory.
