The O Antiphons are about 1500 years old. In the last seven days of Advent, they declare seven names of Christ. They are most commonly known as the verses of the hymn "O Come, O Come Emmanuel."

III
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.

From the beginning You created more than things
but hid in them a seed of Your life force,
for Love cannot make only one, 
embedding life in life, from life.
You are insistent that the making
carries on, in me, in all.
If there is any doubt,
a tree stands ready
to renew my withered spirit.

Seed calls to seed.
I am created.
