“[The T&T Clark Companion to Liturgy] offers a comprehensive overview of current liturgical issues ... [and] it does so in a scholarly yet accessible way, allowing a voice to contrary arguments. It is undoubtedly a required resource for liturgy studies.” ―Catholic Herald

“One of the most detailed, academic and up-to-date accounts of Roman Catholic worship I have come across. All the contributions are of a high scholarship and precise notes and extensive bibliographies accompany all the entries. It brings together a formidable group of liturgical experts ... I recommend it unhesitatingly.” ―Journal of Theological Studies

“[T]he book exemplifies a noble seriousness of purpose, a depth of intellectual engagement, and a pastoral concern with the health of the Western liturgy that makes it an essential reference work for consultation on the host of topics taken up in its pages.” ―New Liturgical Movement

“Immensely scholarly, with nearly 1400 footnotes, this is a book for research students.” ―Theology

“Dom Alcuin Reid has combined a wide variety of sources into a wide-ranging reference book on the liturgy. It provides both a comprehensive introduction and plenty of direction for further exploration.” ―Dominicana

“The work as a whole, with full use of the A-Z, comes well within the capabilities of the keen student. The historical material is presented and arranged consistently and clearly, supported by extensive further reading, and with an eye on implications for current research and religious practice ... Finally, the A-Z not only includes many helpful terms but also a good short listing of further reference works, and these will interest librarians.” ―Reference Reviews

Dom Alcuin Reid is a monk of the Monastère Saint-Benoît in the Diocese of Fréjus-Toulon, France. After studies in Theology and in Education in Melbourne, Australia, he was awarded a PhD from King's College, University of London, for a thesis on twentieth century liturgical reform (2002), which was subsequently published as The Organic Development of the Liturgy with a preface by Joseph Cardinal Ratzinger. He has lectured internationally and has published extensively on the sacred liturgy, including Looking Again at the Question of the Liturgy with Cardinal Ratzinger (2003), The Monastic Diurnal, The Ceremonies of the Roman Rite Described (2009), A Bitter Trial: Evelyn Waugh and John Carmel Cardinal Heenan on the Liturgical Changes (2011). His writings have been translated into Italian, French, German, Spanish, Portuguese, Lithuanian, Polish and Croatian.

Dom Alcuin takes his place at the centre of the new liturgical movement called for by Cardinal Ratzinger (Benedict XVI) promoting an authentic interpretation of the Second Vatican Council's call for liturgical reform within a hermeneutic of continuity, a critical assessment of its implementation and of the need for a reform of the reform, as well as an openness to the value and riches of the usus antiquior in the Church of the twenty-first century. He was the principal organiser of Sacra Liturgia 2013, the international conference on the role liturgical formation and celebration in the life and mission of the Church in Rome in June 2013, and edited its proceedings Sacred Liturgy: The Source and Summit of the Life and Mission of the Church (2014). He coordinates the ongoing Sacra Liturgia initiatives.
