An introductory appreciation, and fourteen chapters contributed by foremost theologians and leaders in the Ecumenical movement, compose this volume of essays on the Ecumenical Hope, in honor of W. A. Visser t'Hooft, on the anniversary of his twenty-fifth year as General Secretary of the World Council of Churches. Contributors include, beside the editors, Jromadka, deDietrich, Sherrill, Florovsky, Congar, Nissiotis, Reinhold Niebuhr, Fischer, M. R. Thomas, Albrecht, and prominent World Council leaders. The central element in the diversity of chapters is the motif of the Ecumenical movement as it finds expression in various countries and confessions. The contributors have been not only participants in this movement but also warm friends of the person they honor. The result is a stimulating, if necessarily incompletely unified, treatment of the central theme. The book will find interested readers among those for whom ecumenicity, particularly as embodied in the life and work of the World Council of Churches, is a lively concern.
