One of the premier interpreters of Pentecostalism, Walter J. Hollenweger has written what is in many ways a sequel to his magisterial "The Pentecostals" (1972). This volume assesses the origins of perhaps the fastest-growing religious phenomenon in this century in light of its current development. Hollenweger contends Pentecostalism is at a critical crossroads in its evolution. Focusing on the theological stories of the Pentecostal movement within the contexts of its "Black Oral Root," "Catholic Root," "Evangelical Root," "Critical Root," and "Ecumenical Root," Hollenweger calls our attention to the significance of this movement for religion, politics, and, indeed the future of the world.

"I know of no one else who has the breadth of knowledge, the depth of understanding, or the grasp of such a broad base of scholarship to be able to write this book. . . . This fascinating book is at times playful, at times deadly serious, and at times simply informative. It will stretch the thinking of all who care to be taught, and challenge the hypocrisy of those who think they know it all. And it will help us all to understand better than we have before, the roots that have nurtured one of the most vital Christian movements in the twentieth century."
