In the past 50 years there have been various attempts to formulate a theology for Christian missions. Missionary Conferences and various studies have stressed the aspects of Christian doctrine essential for the Christian enterprise, but- in view of the editor and contributors to the studies in this book, each has been inadequate to the task. So -- because of the ferment resulting from the events of the past 20 years, 25 important contributors to current Christian thought make their contribution to the rebuilding of a firm theological foundation for the Christian mission in the 1960's. As a glance at the names of the contributors will suggest, this is a challenge rather than a wrapped up theology G. Ernest Wright, Johannes Blauw, Oscar Cullman, Karl Barth, Donald G. Miller, F. N. Davey, Wm. R. Hogg, Franklin H. Littell, Andrew V. Seumois, Ernest Beaz, Paul D. Devanandan, Frank W. Price, Masatoshi Doi, Hendrik Kraemer, A. C. Bouquet, Harold DeWolf, Floyd H. Ross, Paul Tillich, Christian G. Baeta, etc., etc. There is broad perspective here and a thoroughgoing treatment of the many facets of the subject. No serious student of Christian missions can afford to miss it.
