In this volume, Ronald Byars provides an extensive historical and theological study of the development of Eucharist prayer in the Reformed tradition. He introduces early Eucharistic prayer and its development in the Roman tradition, then traces the changes made during the Reformation, and the reform of Eucharistic prayer in modern times. Byars concludes with a recap of recent ecumenical discussions about the prayer, and discusses the current and future place of the prayer in Reformed worship. A glossary of terms and extensive appendices with the texts of historic Eucharistic prayers make this a useful and welcome resource for scholars, students, and clergy.
