From 1919 when a missionary gathering from many countries of the world met at Edinburgh to when it is expected that the World Council of Churches and the International Missionary Council meeting at New Delhi will be merged, seems a long period of time for the churches to take to obey Christ's command to preach to all peoples. Compared however, to the Church's nearly two thousand years of existence, it is a fleeting second. Norman the first steps of the Ecumenical movement from its hesitating beginnings shown as small ""urges"" manifested by scattered groups on the Continent and in England to the highly organized efforts of the 178 churches forwarding the missionary gospel today. is eminently qualified to delicate this history of coalescence through his membership on the staff of both the World Council and the International Council. The book is intricate and detailed reading. For best understanding, it presupposes some knowledge of affairs. However, it should be read by all serious students and laymen who have a keen interest in today's Christianity and who wish to replace narrow parochialism and unintelligent nationalism with the profound extent of the world's need and Christianity's ability to meet that . The author deals with the intricate facts of material organization, but his best when expounding faith and the bright outlook for the unification of that faith.
