This latest addition to the Library of History and Doctrine is the work of a Genevan theologian, translated and compressed by a member of the faculty of Fuller Seminary. Its concern is to find a common ground for ecumenical discussion between Protestants and Roman Catholics. The author seeks this end through examining three main tendencies in modern theology -- the Modern Protestant, the Modern Roman Catholic, and then the ""Evangelical and Catholic"". The roots of this last he finds in Patristic and Reformation theology, and through further study and discussion based on this foundation, he believes a new group for ecumenical rapprochement might be opened. Two main theological positions dominate the author's point of view: Revelation as the starting point of faith; and Christology as the center of faith. Though written with pastoral concern as the heart of the work, the discussion moves in a theological vein more communicative to scholars. A fresh statement of theological matters, however, and a helpful contribution to current ecumenical conversations.
