"Here, at last, is a scholarly and comprehensive account of Pentecostal theology from one of this tradition's leading scholars. It is written in an engaging style and presented in a balanced and non-polemical manner. Warrington has achieved what has not been done before: with lucid clarity and a willingness to engage with differing perspectives, combined with a skilled use of biblical exegesis and abundant secondary literature he has written a volume that will stand as a benchmark for years to come. Pentecostals and Charismatics of every persuasion and those from older Christian traditions will find this an eminently readable text." - Allan Anderson, Professor of Global Pentecostal Studies, University of Birmingham, UK
