Proclamation of Christmas

"At the Office of Prime, in cathedral chapters and monasteries, the announcement of tomorrow's feast is made with unusual solemnity.  The lector, who frequently is one of the dignitaries of the choir, sings, to a magnificent chant, the following lesson from the Martyrology.  All the assistants remain standing during it, until the lector comes to the word Bethlehem, at which all genuflect, and continue in that posture until all the glad tidings are told." Dom Gueranger
