This book explores the Pentecostal and charismatic movements, tracing their development and their variety. Hocken shows how these movements of the Holy Spirit, both outside the mainline churches and as renewal currents within the churches, can be understood as mutually challenging and as complementary. The similarities and the differences are significant. The Messianic Jewish movement possesses elements of both the new and the old. Addressing the issues of modernity and globalization, this book explores major phenomena in contemporary Christianity including the relationship between the new churches and entrepreneurial capitalism.
