This is the 5th book in the English language translation of the pre Pius X Divine Office by the Marquess of Bute. The classic book includes the Rubrics or Rules for praying the Breviary as well as the Commons of Saints which is used throughout the year. As well, you'll find the complete Roman Calendar and additional Offices, such as that to the Blessed and Ever Virgin Mary Mother of God. A priceless addition to the library of any Traditional Roman Catholic interested in deepening his or her spiritual life in the Church.
