Norman can write better about the ecumenical movement than Dr. Samuel McCrea Cavert, the distinguished secretary of the World Council of Churches, who has been immersed for almost all his adult years in the movement to bring the Churches into closer relationship. His work antedates World War I, and he has been friend and confidant of such men as Archbishop Temple. Bishop Soderblum, and Dr. William Adams Brown. Dr. Cavert has chosen his title with care, in indicate that there has been considerable movement in the direction of a united Church and that Christian Unity still has a long, long way to go. The book started as The Hoover Lectures at the Disciples Divinity House at the University of Chicago. Its significance was recognized, and the result is this expanded form of those original talks. The summery of the ecumenical movement is skilfully done, and with a blessed minimum of words. Of particular tuberest is to read the careful analysis by this well informed person of the relationship of the ecumenical movement to the Roman Church and to the Orthodox. Whether or not we have great concern for the unity of the people of Christ, we will find ourselves far by Dr. Cavert's sketching of the problems we face, the decisions which we must make and the opportunities that constantly arise as God leads his people towards each other once again.
