The Liturgical Subject brings together in one volume a wide and sometimes divergent range of understandings of the liturgy. Written primarily by Roman Catholics, with one important ecumenical contribution, the publication of these essays at this moment is particularly apt. They reflect the widespread reassessment of various aspects of especially the post-Conciliar period of liturgical reform. At the same time the collection indicates how liturgical study is called to account by, and is itself able to question, the philosophical aspects of its work. This is an area of enquiry as yet in its infancy, whose contours are nevertheless already discernible in the papers gathered here. This volume is a landmark for research of this kind, pointing toward further ecumenical dialogue and contributing to more fundamental studies of liturgy.
