"For this end the Only-Begotten Son of God took on Him the Form of our infirmity; for this the Invisible appeared not only Visible, but even despised; for this He endured the jests of contumely, the reproaches of derisions, and the torments of sufferings, that God in His Humility might teach man not to be proud. How Great then is the Virtue of Humility, since for the sole purpose of truly teaching it, He Who above estimation is Great, became Little, even to Suffering? For since the pride of the devil cause the origin of our fall, the Humility of God was found out as the Instrument of our Redemption. For our enemy who was created great above all things, wished to appear exalted above all things. But Our Redeemer remaining Great above all things, deigned to become Little among all things."
(St. Gregory the Great, the Dialogist [+604], Book 34, Sec. 54, "Morals on the Book of Job"]
