Book excerpt: A survey of 'spiritualities of the Spirit' embracing both the Pentecostal tradition and the charismatic movement in the major western churches. There are an estimated 500 million ‘Pentecostal’ or charismatic Christians, often belonging to relatively new churches, and they make up the most vibrant and fastest-growing parishes and communities in the world. Yet as Mark Cartledge shows, charismatic spirituality has been a feature of Christianity from the earliest days, even if aspects of it have often been marginalized and ignored. His masterly introductory survey, ideal for both the general reader and the student, traces the movement back to the Bible and the work of Tertullian, to Montanism, Simeon the New Theologian, Joachim of Fiore, John Wesley, and recent charismatic and neo-charismatic renewal sources.
