A penetrating and thorough-going study of the plight of the inner city church as the Protestant Church follows-or precedes- its members to the suburbs and exurbs, leaving behind those who cannot alone afford to maintain the church or attract and provide for an adequate ministry. Dr. Gibson Winter, of the faculty of the University of Chicago, does much more than view the situation with alarm. He studies the role of the churches in the metropolis, and the part which they could play in its planning and growth. He describes the possibility and function of a joint ministry shared by several Protestant Churches, and ministering to the needs of a sector of the city, thus helping to integrate it, instead of stepping up its fragmentation by persisting in fragmentary ministries to separate groups. Much of this material is projected from successful experiments in such an approach to the inner city's religious problems, and leads to the endorsement of ordination to extended and augmented ministries in the direction of current proposals for Church unity. Such a complete and sobering study as this must be read by all who plan for, or work in, the Protestant ministry to those who cannot or will not leave the city.
