The “O” Antiphons are one of the treasures of the Christian liturgical tradition, sung during the last week of Advent, from December 17 to 23, in preparation for the celebration of the birth of Jesus Christ. Their name comes from the fact that each one begins with the exclamation “O,” followed by a title describing a prophetic or theological characteristic of Christ.
These antiphons are mainly used at Vespers, within the Liturgy of the Hours, and have a dual purpose: to recall the messianic prophecies of the Old Testament and to prepare the believer’s heart for the coming of Jesus. Their origin is ancient, with roots in the early Church, and they stand out for their poetic beauty and spiritual depth.

As Christmas draws near, the “O” Antiphons invite us to pause, meditate, and prepare our hearts for the birth of the Savior of the world. Each antiphon reminds us of an aspect of Christ: His wisdom, power, light, and infinite love. Listening to and contemplating them is a way to open ourselves to the hope, faith, and joy that Christmas brings, making our anticipation a time of genuine spiritual preparation.
We will publish a reflection on each antiphon to deepen its meaning and allow ourselves to be guided in our preparation for the birth of the Savior, making these days before Christmas a time of true meditation and hope.
