Available Today: Monastic Breviary Matins
It's available today. Monastic Breviary Matins, once the rarest of treasures, is in print again. Lancelot Andrewes Press has made this invaluable volume available for $45, which includes shipping and handling. You can see the details here (PDF). You can order here, if you scroll down far enough.
It's worth noting, this is in no way a new translation or LAP's own compilation. This is the Divine Office according to the Breviarium Monasticum, the Divine Office according to the Rule of St. Benedict. Monastic Breviary Matins is the companion to the Monastic Diurnal and was originally published in 1961 by the Society of the Sacred Cross in Tymawr, Wales. It runs more than 1,200 pages.
While it has always been possible for those so interested to pray the full Divine Office in the ancient Benedictine tradition, these two volumes make the material far more accessible to English-speakers, laymen, and, may the Lord grant it, aspiring oblates and future vocations.
Our proverbial biretta is off to LAP for this.
