The “O Antiphons” belong to Christian antiquity. The Roman philosopher Boethius, who lived in the late fifth and early sixth centuries, alludes to them in his writings. One scholar suggests that, “in some fashion, the O Antiphons have been part of our liturgical tradition since the very early Church.” And, since at least the eighth century, the “O Antiphons” have been set aside for the week preceding Christmas Eve, December 17 to 23. The Colson Center has prepared a free, downloadable booklet featuring an explanation of each of the O Antiphons, a short meditation on their meaning, and quotes from Christians throughout history on the wonder of Advent. The booklet is called Emmanuel: Readings for Advent.
