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."

II
O Adonai, and leader of the House of Israel,
who appeared to Moses in the fire and the burning bush
and gave him the law on Sinai;
Come and redeem us with an outstretched arm. 

When I dare approach
with closed lips and open heart,
a new sense is awakened: love.
Still and real, textured with presence,
heavy lightness, true.
My ambitious mind attempts description,
finding language flimsy, blunted, small.
Drop the constant, clumsy consonants;
avow with simple vowels resonant: Ah! Oh!
