In Thomas Merton’s Seasons of Celebration, he writes in his essay entitled “Advent: Hope or Delusion?” that “St. Gregory the Great said that all Christians should continue the prophetic mission of John (the Baptist) and point out the presence of Christ in the world.”  Merton continues, “This may mean many different things. John was able to point out Christ at the Jordan, in a moment of fulfillment, which gave meaning to his whole life.  But John also had to witness to Christ in prison, in the face of death, in failure, when even the meaning of his other glorious moment seemed to have been cancelled out.”

Merton goes on to say, “our task is to seek and find Christ in our world as it is, and not as it might be.  The fact that the world is other than it might be does not alter the truth that Christ is present in it and that his plan has been neither frustrated nor changed: indeed, all will be done according to his will.  Our Advent season is the celebration of this hope.  What is uncertain is not the ‘coming’ of Christ but our own reception of him, our own readiness and capacity to ‘go forth to meet him.’ We must be willing to see Him and acclaim Him, as John did, even at the very moment when our whole life’s work and meaning seem to collapse.”

During the last week of Advent, in the octave before Christmas, the Church experiences a quickening of Hope, a strengthening of Faith, and the power of Love to transform us.  A special set of prayers, acclamations called the “O Antiphons” are used at this time.  These seven antiphons are recited (or chanted) preceding and following the Magnificat during Evening Prayer.

The usage of the “O Antiphons” has been part of the liturgical tradition since the very early Church. The exact origin of the “O Antiphons” is not known. Boethius (c. 480-524) made a reference to them, which suggests their presence at that time. By the eighth century, they were in use in the liturgical celebrations in Rome.

The importance of the “O Antiphons” is twofold: each one highlights a title for the Messiah, a way we might know Christ; and each one refers to the prophecy of Isaiah concerning the coming of the Messiah.  The antiphons confess the faith of the community by acknowledging the identity of the one they address.

The invocation – O, Come!—professes the Church’s hope that, since Our Lord has always revealed himself as the one who is to come, we therefore will be ready to say with the spirit and the Bride, come Lord Jesus.  These prayers unite our hearts with the heart of God, the one who is coming, our redeemer.  The antiphons can be found as hymn 56 in in our hymnbook.

O Sapientia:  O Wisdom (December 17)  

Isaiah 11:2-3
The spirit of the Lord shall rest on him, the spirit of wisdom and understanding, the spirit of counsel and might, the spirit of knowledge and the fear of the Lord.
