It is wonderful during Advent to hear so much from the prophets in our readings at Mass. Today's first reading comes from Isaiah 11, and you may recognise it if you have been to the service of Nine Lessons and Carols before. It speaks of the peace the Messiah will bring to the earth:
On that day, A shoot shall sprout from the stump of Jesse, and from his roots a bud shall blossom. The Spirit of the LORD shall rest upon him: a Spirit of wisdom and of understanding, A Spirit of counsel and of strength, a Spirit of knowledge and of fear of the LORD, and his delight shall be the fear of the LORD. Not by appearance shall he judge, nor by hearsay shall he decide, But he shall judge the poor with justice, and decide aright for the land's afflicted. He shall strike the ruthless with the rod of his mouth, and with the breath of his lips he shall slay the wicked. Justice shall be the band around his waist, and faithfulness a belt upon his hips.
Then the wolf shall be a guest of the lamb, and the leopard shall lie down with the kid; The calf and the young lion shall browse together, with a little child to guide them. The cow and the bear shall be neighbors, together their young shall rest; the lion shall eat hay like the ox. The baby shall play by the cobra's den, and the child lay his hand on the adder's lair. There shall be no harm or ruin on all my holy mountain; for the earth shall be filled with knowledge of the LORD, as water covers the sea.
On that day, The root of Jesse, set up as a signal for the nations, The Gentiles shall seek out, for his dwelling shall be glorious.
Here is a musical setting of this beautiful text by Charles Villiers Stanford. This is one of his six Bible Songs, each of which is almost a short cantata. Listen out for Stanford's clever use of the famous 'Veni, veni emmanuel' plainsong, introduced as the second theme in this piece.
