It is no secret that the Pentecostal movement has had an incredible impact on the shape of worldwide Christianity in the past century. It is estimated that Pentecostals and charismatics comprise approximately one-fourth of Christians worldwide, and the numbers are only expected to grow, especially in Asia, Africa, and Latin America. With these developments comes the need for theologians and students to understand the theological framework of this burgeoning movement.

The Spirit Poured Out on All Flesh, named one of the "Fifteen Outstanding Books of 2005 for Mission Studies" by the International Bulletin of Missionary Research, is one scholar’s attempt to develop a thoroughly Pentecostal theology and, perhaps more importantly, to bring this theology into dialogue with other theological traditions. Amos Yong outlines a pneumatological approach to soteriology, ecclesiology, theology of religions, theology of creation, and the nature of God–particularly in regard to trinitarian formulations vis-à-vis Oneness theology.

This volume is more than a beginning systematic theology, however. The first chapter provides a fascinating survey of worldwide Pentecostalism, examining how various theological issues and questions are being addressed "on the ground." Further, the author argues that because of Pentecostalism’s global origins, its theology can be a great gift to Christianity at large, and he proposes that it can play a large role in shaping a truly global theology.

Yong is one of a very few pentecostal theologians today who are seeking to understand the relationship between pentecostalism and global issues, and he is perhaps the only one to do so in a sustained manner. In this volume, Yong offers a pentecostal perspective on ecumenism, world religions, and culture with a view toward developing a distinctively pentecostal global theology. Whether one agrees or disagrees with his methodology and conclusions, Yong’s contributions cannot be ignored.–Simon Chan, Earnest Lau Professor of Systematic Theology, Trinity Theological College, Singapore

The Spirit Poured Out on All Flesh is an invigorating book. Reflecting upon global pentecostal experiences and practices, Yong has taken his pneumatological imagination to new depths of insight in his quest for a more robust trinitarian theology. The result is a multiperspectival reformulation of Christian theology that allows fresh winds of the Spirit to blow through old doctrines.–Dale T. Irvin, academic dean and professor of world Christianity, New York Theological Seminary
