On the evening of December 17 the final phase of preparation for Christmas begins with the first of the great “O Antiphons” of Advent. These prayers are seven jewels of liturgical song, one for each day until Christmas Eve.

From today the prayers and readings take on a different nature.
In the first half of Advent we count forwards: first week, second week, and so on, paying attention to Advent Sunday, the day when Advent started.
Now the second half of Advent has begun, and Advent Sunday is forgotten: it is Christmas Day that matters. Today is the eighth day before Christmas, tomorrow is the seventh day, and so on. The prayers follow this countdown, and the final readings from Isaiah build up to their climax. [/FONT]

These prayers are seven jewels of liturgical song, one for each day until Christmas Eve. They seem to sum up all our Advent longing for the Savior.
