Simply the best book available on the development of the daily prayer of the Church, that ''sanctification of time'' in which the Church is invited to transfigure earthly existence with an anticipation of the ceaseless praise of the age to come. The evolution of Matins, Vespers, and vigils in early Christianity is comprehensively detailed in this learned work, comparable to the work of Bouyer, Jungmann, or Dix on the eucharistic liturgy. 421 pp.
An Eighth Day View:
This work focuses on the origins and development of the Divine Office and how it can be traced through both Eastern and Western branches of the Church, providing a wealth of historical and liturgical information.
