Origen, on Ezek 16:49

“Behold this was the iniquity of Sodom thy sister, pride, fulness of bread, and abundance, and the idleness of her, and of her daughters: and they did not put forth their hand to the needy, and to the poor.”

“What then is the sin most great of all sins? It is the one for which the devil fell.… Pride is greater than all sins, and the principal sin of the devil.… Often the reason for pride is for him who disregards having an ecclesiastical dignity.”
