Part 1: Bethlehem
As I ... listened to the familiar beginning of Messiah, it was easy to understand how the oratorio came to be associated with the Advent season. Handel begins with a collection of lilting prophecies from Isaiah about a coming king who will bring peace and comfort to a disturbed and violent world. The music builds, swelling from a solo tenor ("Comfort ye my people ... ") to a full chorus joyously celebrating the day when "the glory of the Lord shall be revealed."
Part 2: Calvary
Part 1 ends with a scriptural invitation ("Come unto him") based on a paradox; Part 2 explains the paradox of how his yoke can indeed be easy, and his burden light. It is because of a transfer of suffering. At the cross, the pain and sorrow of humanity became the pain and sorrow of God. The chorus early on states it well: "Surely, he hath borne our griefs, and carried our sorrows ... and with his stripes we are healed."
Furthermore, in that act death itself died. What happened next, on the day of resurrection, was a miracle deserving of all praise, deserving of the "Hallelujah!" chorus.
Part 3: EternityHandel's Messiah could not rightly end with the "Hallelujah!" chorus. The Messiah has come in "glory" (Part 1); the Messiah has died and been resurrected (Part 2). Why, then, does the world remain in such a sorry state? Part 3 attempts an answer. Beyond the images from Bethlehem and Calvary, one more messianic image is needed: the Messiah as Sovereign Lord. The Incarnation did not usher in the end of history—only the beginning of the end. Much work remains before creation is restored to God's original intent.
