content: Stephen Ray's book, Upon This Rock, is the most comprehensive book I have read on the subject of the position the Bishop of Rome holds in the Christian community, even if some do not recognize that position. It is the most thoroughly documented discussion available on the primacy of Peter in the early Church, and the primacy his successors in office have in the Church today. This book belongs in the library of every thinking Christian, Catholic or not.James H. Dobbins, Ph.D.Author of Take My Hand
