Bonaventure — on Phil 2:7 (Disputed Questions on Evangelical Perfection, Question 1)

“On that passage Bernard says in a sermon on the Nativity of the Lord: "What necessity was there for the God of majesty to so empty himself, so humble himself, so diminish himself, unless that you should do likewise? Already he cries out by example what he will preach by word." And shortly after: "It is intolerable impudence that, where majesty emptied itself, a little worm should puff itself up and swell with pride." If therefore we ought to imitate Christ in such self-emptying, it remains that to be abased belongs to the perfection of virtue.”
