i. A psalm of David. These words are very familiar, for they are so to say pinned to the doors as a royal inscription. But the heading does not say: "Read and depart," but: "Read and draw near." So let us reverently enter to the mighty works of the Lord, for this psalm will discuss fully but briefly both the Lord's sacred incarnation and His almighty divinity. In certain passages He is seen to utter words of similar loftiness or beauty, as at the beginning of the celebrated gospel where it says: In the beginning was the Word, and the Word was with God, and the Word was God. 1 So the psalm is, so to say, the sun of our faith, the mirror of the heavenly secret, the chest of the holy Scriptures, in which all that is told in the proclamation of both testaments is spoken in summary. So we must hold it fast in love, for its sweetness swells to attain the worth gathered in its succinct brevity. Now let us fearlessly listen to its divisions, for it is marked out with variation of spokesmen.

When he adds: Sit thou at my right hand until I make thy enemies thy footstool, and: The Lord sends forth the sceptre of thy power out of Sion, and thou wilt rule in the midst of thy enemies, the substance of His humanity is being declared which could receive what it did not have. In the second section, the Father begins to reveal the nature of His divinity to a limited extent, in accordance with the feeble limit of our capacity to understand. He says: With thee is the principality in the day of thy strength, in the brightness of the saints. From the womb before the day‐ star I have begotten thee. In the third part the prophet speaks until the end, again revealing the shape of His humanity when he says: The Lord hath sworn, and he will not repent, and the rest. Thus in these sections
