In the Traditional Breviary Office, still used by Traditional Institutes such as the Priestly Fraternity of St Peter, the Martyrology is read at Prime, the third Office of the day in the early morning. The Martyrology is always 'anticipated', i.e. read the day before the Feasts mentioned in the reading. Usually, it is just one or two lines about a Saint or Mystery, but today's reading begins with a longer section. Even if I don't say Prime, I always read this. When my children were still at home, I read this as an introduction to Grace before the Christmas Feast meal.
So, this morning, this will be read by Priests and laymen round the world, in great anticipation of the joy of the Mass at Night.
