Following an analysis of the postmodern world, the legacy of the Enlightenment, and Christian faith into a postmodern age, Professor Bosch sketches the contours of a missiology of Western culture. The latter includes considerations of mission as social ethics, mission and the Third World, and God-talk in an age of reason. A concluding section summarizes the five ingredients of a missiology of Western culture, that is, that it include an ecological dimension, that it be countercultural and ecumenical and contextual, andthat it be primarily a ministry of the laity.
