How did charismatic renewal transform the churches in the twentieth century, moving from the periphery to the mainstream? In Age of the Spirit, John Maiden looks at the rise of charismatic Christianity before, during, and after the 'long 1960s' across the English-speaking world. The book is a highly readable, compellingly argued account of one of the most significant ecclesial phenomena of the 20th and 21st centuries. It will be an essential reading for those interested in the impact of charismatic renewal on mission and evangelism, particularly church growth theories, in Pentecostalism and global Christianity in contemporary times.
