On a grant made possible to the National Council of Churches by the National Coffee Association, the author made a study of the burgeoning Coffee House movement which is rapidly becoming one of the newer activities -- if not form of ministry -- of Protestant churches. Over a thousand such Coffee Houses, of widely divergent characteristics, are in operation in 1966, an increase of five hundred percent over 1965, and the end is not yet. The author's aim is to provide a theological basis for this type of church enterprise, and then to give practical help on a wide variety of operating details, from decor to the training of volunteer workers. While much of this may be useful to aspiring Coffee House evangelists, the book leaves the reader wishing for more of a report of the actual experience of existing houses, and a greater sense of the dimension of both faith and wisdom that seem to be required if significant results are to follow. An occasional phrase such as ""Sitz im Leben"" reveals the fact that the author is only recently out of seminary.
