The celebration of the liturgy of the Holy Eucharist is one of the central issues in the Roman Catholic Church today. To mark the "Year of the Eucharist", the Society of St. Catherine of Siena held a conference on the Eucharistic liturgy at Oxford in 2005. This book contains the energetic and fruitful reflection of the scholars present at the conference. The contributions are academically demanding yet accessible to a wider audience. The collection does not seek a solution to the current problems, rather it promotes an open discussion about the theological, philosophical and historical issues surrounding the celebration of the liturgy and its future as well as paying attention to the increasing interest in the pre-conciliar rites.
