African Pentecostalism is one of the most vibrant expressions of Pentecostalism in the world today. There are over 100 million Pentecostals in Africa, and the movement continues to grow. So significant is the Pentecostalization of global African Christianity, it is referred to as an African reformation. No serious study of global Pentecostalism can be conducted without a critical look at African Pentecostalism. In Pentecostalism: Insights from Africa and the African Diaspora, Clifton R. Clarke explores the historical and theological factors behind the phenomenal growth of African Pentecostalism. Clarke provides insightful elucidation on critical religious, theological, philosophical, political, and social issues that have shaped the movement. His extensive account examines such topics as: theological method for the study of African Pentecostalism, African Pentecostalism and Islam, Pan-Africanism and African Pentecostalism, the African Pentecostal understanding of God, and Christ and the Holy Spirit. What is the cause of this African Pentecostal revival? Clarke points to such features as its vibrant approach to worship and a robust emphasis on the Holy Spirit, its aggressive evangelism and church growth strategies, and its ability to tap into African imagination and felt needs in a way that is culturally relevant and contemporary--all of which has contributed to African Pentecostalism's global attraction.
