The O Antiphons
For seven days before Christmas, the Church has prayed these ancient texts, each one a title of Christ, and together, a hidden message.
In the final days of Advent, as the darkness deepens and Christmas draws near, the Church gives us some of her most ancient and beautiful prayers. They're called the O Antiphons, seven short texts, one for each evening from December 17 through December 23. Each begins with "O" and addresses Christ by a different title drawn from Scripture.
You may not know them by name, but you've almost certainly sung them. The hymn "O Come, O Come Emmanuel" is built from these antiphons. Each verse corresponds to one of the seven prayers.
But there's more to them than the hymn reveals.
Seven Titles, Seven Days
The antiphons were prayed by monks at Vespers, the Church's evening prayer, as early as the eighth century. Each one frames the Magnificat, Mary's great song of praise, with a title of Christ and a plea for his coming.
O Sapientia, O Wisdom, ordering all things. Come and teach us.
O Adonai, O Lord, who appeared to Moses in fire. Come and redeem us.
O Radix Jesse, O Root of Jesse, sign among the peoples. Come and deliver us.
O Clavis David, O Key of David, who opens what no one can shut. Come and free the prisoners.
O Oriens, O Dayspring, splendor of light eternal. Come and enlighten those in darkness.
O Rex Gentium, O King of the Nations, cornerstone making both one. Come and save us.
O Emmanuel, O God With Us. Come and save us, O Lord our God.
Each title is drawn primarily from the prophet Isaiah. Together, they form a portrait of the Messiah, wisdom and lord, root and key, light and king, and finally, presence. God with us.
A Hidden Message
Here's something most people don't know.
If you take the first letter of each Latin title and read them backward, from December 23 to December 17, they spell out a phrase: ERO CRAS.
It means: "Tomorrow, I will come."
The monks who arranged these antiphons buried Christ's answer inside the prayers themselves. We cry out to him with longing, and hidden in the structure of our longing is his promise: I am coming. Tomorrow.
That's the kind of beauty the Church has been quietly handing down for over a thousand years.
Light on the Darkest Day
Notice that O Oriens, O Dayspring, falls on December 21, the winter solstice. The shortest day. The longest night.
On the darkest day of the year, the Church prays to Christ as the dawn, the rising light, the sun of righteousness. It's not an accident. The liturgy pays attention to creation. And creation, in its rhythm of darkness and returning light, tells the story of what we're waiting for.
Praying the Antiphons
You don't have to be a monk to pray these texts. During these seven days, let the antiphon for that evening shape your prayer.
Read it slowly. Let the title sink in. O Wisdom. O Key of David. O Emmanuel. Ask yourself: what does this name of Christ mean for my life right now? Where do I need wisdom? Where do I feel locked up, waiting for a key? Where do I long for God to be present?
If you pray with your family, light the Advent wreath and read the antiphon together. Sing a verse of "O Come, O Come Emmanuel." Let the final days of Advent slow down rather than speed up.
The world rushes toward Christmas. The Church lingers. These seven evenings are a gift, an invitation to wait with intention, to name our longing, and to hear, hidden in the ancient words, the Lord's quiet response.
