The history of liturgical celebration seen through the annual change of seasons and the Church's liturgical calendar.

On July 7, 2007, Pope Benedict XVI issued his long awaited motu proprio, Summorum Pontificum. In this document he granted permission "to celebrate Mass following the typical edition of the Roman Missal promulgated by Bl. John XXIII in 1962 as an extraordinary form of the Liturgy of the Church." Because of this motu proprio, there has been much interest in viewing the Paul VI missal as a continuation of the Bl. John XXIII missal. Understanding the earlier ritual expression is essential if we are to deeply understand the ordinary expression of the Mass of Paul VI. This book is a collection essays from the proceedings of the 11th International CIEL (International Centre for Liturgical Studies) Colloquium held at Merton College, Oxford, September of 2006. CIEL is an academic school of Liturgy founded in 1994 in Paris to form an academic school to instruct priests, seminarians, religious and the laity in the riches of Catholic liturgical history and development of the liturgy.

The "Handbook for Liturgical Studies" provides a complete course of liturgical studies in five volumes. It is offered as a model, source, and reference for students of liturgy and liturgical ministry. Through the study of these five volumes, readers are led to an active and spiritually fruitful participation in the ecclesial celebration of Christ's mystery desired by the Second Vatican Council.

In 1921, Anton Baumstark delivered two lectures on the development of the Roman Rite to a gathering at the Abbey of Maria Laach. Abbot Ildefons Herwegen offered to publish those lectures, but Baumstark decided to write a book on the topic instead, which was published two years later as On the Historical Development of the Liturgy. It would be another sixteen years before he produced Comparative Liturgy, for which he is better known. Together the two books lay out Baumstark's liturgical methodology. Comparative Liturgy presents his method; On the Historical Development of the Liturgy offers his model. For nearly a century, On the Historical Development of the Liturgy has been valued by specialists in the field of liturgical studies, both for its description of comparative liturgy and for the portrayal of patterns Baumstark discerns in liturgical development. Also significant are the hypotheses Baumstark proposes and the evidence he brings to bear on problems in liturgical history. In this annotated edition, Fritz West provides the first English translation of this work by Anton Baumstark.

Open Access for this publication was made possible by a generous donation from Segelbergska stiftelsen för liturgivetenskaplig forskning (The Segelbergska Foundation for Research in Liturgical Studies). In a seminal study, Cur cantatur?, Anders Ekenberg examined Carolingian sources for explanations of why the liturgy was sung, rather than spoken. This multidisciplinary volume takes up Ekenberg’s question anew, investigating the interplay of New Testament writings, sacred spaces, biblical interpretation, and reception history of liturgical practices and traditions. Analyses of Greek, Latin, Coptic, Arabic, and Gǝʿǝz sources, as well as of archaeological and epigraphic evidence, illuminate an array of topics, including recent trends in liturgical studies; manuscript variants and liturgical praxis; Ignatius of Antioch’s choral metaphor; baptism in ancient Christian apocrypha; and the significance of late ancient altar veils.
