O Radix Jesse… These are the opening words of the traditional antiphon on Dec. 19 each year (that the cover art of this prayer guide depicts). In English the prayer is worded this way:
O Root of Jesse, standing as a sign among the peoples;
before you kings will shut their mouths,
to you the nations will make their prayer:
Come and deliver us and delay no longer.
The “Root of Jesse” is an image used by the Prophet Isaiah in his eleventh chapter. This “Root” will come and deliver the people Israel and extend their territory to the ancient boundaries promised to the Patriarch Abraham. Paul quotes Isaiah 11 in Romans 15:12 and interprets the prophecy not to be about the extension of the kingdom of Israel, but the gathering of the nations into the Church. Just as in Micah 7:11-12, Isaiah’s prophecy, and indeed the Lord’s promise to Abraham, is fulfilled in the Church, whose boundaries extend to the ends of the earth and whose inhabitants include every tongue, tribe, and nation. The above prayer then is for the prophesied One to come and deliver us. The need is urgent. “Delay no longer!” we cry.
Root. Radix. The interesting thing about the concept of the Root of Jesse in the text of Isaiah is that it is not entirely clear who the Root is. Is Jesse the Root from which Christ springs? 11:1 certainly leads us in this direction. Or, on the other hand, is Jesus the Root from which Jesse springs? Verse 10 leads us in this direction. The answer to the question is, “Yes.” Jesus Christ is both the Root and the Shoot, he is the Alpha and the Omega, the first and the last, the author and the finisher of our faith. He is Ancient of Days and yet lately born. He ushers in the beginning and also the end. Jesus is the Root, the ancient ancestor of Jesse and also the Shoot, the one who springs forth from Jesse’s lineage to usher in the everlasting kingdom and the renewal of all things. Jesus is David’s son and David’s Lord.
Radix. This Latin word for “Root” is where we get the word radical. Jesus is radical. Jesus gets to the root of things and he calls us to get to the root of things. The word radix is also where we get our modern abbreviation for medicine. Rx is an abbreviation for radix because many ancient medicines were made from the roots of things. Jesus is radical. He gets at the root. He is our medicine. Come, O Root, and deliver us!
The most important thing to remember about Advent is that Advent is not Christmas. The word “advent” is from the Latin advenire which means “to come to.” Advent is a season reflecting on the “comings” of Jesus. There are three distinct comings of Jesus that are in view in the season of Advent. The first coming was in the past and was the birth of our Lord Jesus. The second coming is at the end of history and is the bodily return of Jesus Christ to judge the earth. Yet there is another coming of Jesus that we should not miss. The third coming is how we long for Jesus to appear and visit us now, in the present, to right wrongs and advance the kingdom of God in this world. In Advent we do cry out for Jesus to come again. But we also look for his coming to us today in his Word, in the sacrament of the Eucharist, and in the faces of our brothers and sisters in Christ who bear his image. Christ comes to us in all these ways, and we need him to come. We need him to visit us this Advent. Come and deliver us and delay no longer!
As we look around us we see a great need for The Root to come and deliver us. We have our own personal needs. We have the needs of our church and our community. There are national crises that we should be concerned about. We need the Lord to come. Now! we cry. Come quickly, Lord Jesus. This is the spirit of Advent.
The Good News is God will answer our cry for deliverance. The Root has come to set us free. The Root will come again to renew all things. And the Root promises to meet us in the here and now. He promises to be present with us through His Word. He promises to be present with us through his sacrament. He promises that when two or three of us are gathered together in His name, he will be smack dab in the middle of us.
This Advent let us commit ourselves to preparation and prayer in joyful and hopeful expectation that King Jesus will come and deliver us. Let us watch and pray and not give in to despair, though it seems he never hears us and never answers us. Many times, when we are praying we are expecting a big act of God, a mighty work, a life changing event. But often God, in His infinite wisdom, chooses to give us a sustaining grace instead of that life changing event we prayed for.[1] We may wonder why he does this, when we know he has the power to move mountains and stop time. Maybe he does it because His greatest desire for us is that we would be satisfied with what he daily gives us in his regular, ordinary comings to us: The very substance of his Son, Jesus Christ.
Jesus is enough. Let us be satisfied with Him.
