Owen Cummings has written a fascinating study of history and theology that centers on the development of Eucharist in the Anglican church. He examines the work and writings of twentieth-century theologians but in doing so discusses topics that have both divided the Anglican and Roman Catholic churches; he also opens up the conversation to where unity can be found. The historical background he provides is both informative and helpful in providing a context for the current understanding of Eucharist in the Anglican church with its wide scope of beliefs. There is no other book on the market on this subject. It is an outstanding contribution to the knowledge and understanding of ecumenical theology.
