Psalms 144:5

The psalmist is a witness of this matter when he says, "All have gone astray together; they have become worthless." And Christ's prophets, praying for help, said, "Lord, bow down your heavens and descend"; not that he might change the places in which all things are now located but that he might take on the flesh of human weakness for our salvation. Paul says the same thing: "How, being rich, he became poor for our sakes, that by his poverty we might become rich." And he came to the earth and proceeded as a man from the virgin's womb, which he sanctified. Confirming by this process the interpretation of his name, Emmanuel, that is, "God with us," he began in a marvelous way to be what we are and did not cease to be what he was. He assumed our nature in such a way as not to lose what he himself was.

I consider this to be connected with my present subject. For in his wonder at the knowledge of God the Word coming to people, the psalmist is astonished beyond measure at the love by which he descends from his divinity, and lessens his natural majesty and reckons the human race worthy of bearing him. So here he prays, saying, "Lord, bow the heavens and descend." While in the seventeenth psalm [LXX] it is written, "And he bowed the heavens and descended, and it was dark under his feet. And he rode on cherubim and flew, he flew on the wings of the winds," wherein there is a prophecy of his ascension from earth to heaven. And when there is a fit opportunity I will show that we must understand the descent and ascension of God the Word not as of one moving locally, but in the metaphorical sense that Scripture intends in the use of such conventional terms.

Lord, bow down your heavens, and descend. You will not be able to save this vileness of man, unless you yourself put it on. Lord, bow down your heavens, and descend. Your straying sheep will not be able to be healed, unless it is carried back on your shoulders. Touch the mountains, and they shall smoke. 'Amen I say to you: if you shall have faith like a grain of mustard seed, you shall say to this mountain, Pass over, and it shall be transferred.' There it was being said concerning the lunatic. Concerning that mountain, which could not be transferred by them, it is written in Jeremiah: 'Give glory to the Lord our God, before your feet stumble against the dark mountains.' Why have we said all this? Because now too there follows, Touch the mountains, and they shall smoke. The mountains that reign, the mountains that are raised up through pride, who say 'The rivers are mine, and I made them.' Touch the mountains, and they shall smoke. He did not say, they shall be set ablaze; but, they shall smoke. Let them have the token of punishment: not of blaze, not of splendor.
