The first of a two-volume analysis of theology in Wales, this volume begins with the publication of Bishop William Morgans Bible in 1588 and concludes with the first phase of the Evangelical Revival in 1760. It assesses the development of Puritanism and of doctrine within the Church of England, Dissenting theology including Calvinism and Arminianism, the doctrinal vision of Griffith Jones Llanddowror, and the way in which an evangelistically vibrant moderate Calvinism contributed to the rise of the Methodist movement. As well as evaluating thought and ideas, it assesses the contribution of such vivid personalities as Morgan Llwyd, Charles Edwards, James and Jeremy Owen, Daniel Rowland and William Williams Pantycelyn.
