Mark Cartledge's book is unique in integrating charismatic and empirical perspectives in practical theology. It exemplifies both qualitative and quantitative methods of research, and suggests a way forward for the emerging field of charismatic theology. In part one, Cartledge offers a proposal for the development of a charismatic practical theology. He surveys the different models of the interaction of practical theology and social sciences and defends one that is consistent with charismatic spirituality. The section also explores how charismatic spirituality affects theories of truth and knowledge by making testimony an integrating center, before concluding with a clear explanation of the methods of research employed. Part two progresses into six empirical studies on charismatic worship, glossolalia and postmodernity, women and prophetic activity, the Toronto Blessing, healing, and socialization. Each chapter of this important book ends with a methodological reflection and suggestions from renewed theological praxis, enforcing the values of such methods of study for a clearer understanding of charismatic Christianity.
