Antiphons On The Benedictus
Accompanying the O Antiphons are two Antiphons said at Lauds, on December 21 and 23, also relating to the theme of the upcoming birth of Christ. The first, due to the feast of St Thomas falling on December 21, is traditionally used instead in the commemoration of the feria. With the transference of this feast to July 3 in the revised calendar, these are again used in the Liturgy of the Hours as antiphons. The Monday through Saturday which fall on the days of the O Antiphons also have their own antiphons for the psalms of Lauds, rather than repeating the antiphons of the previous Sunday, as is otherwise done in Advent.
