This book is a collection of closely-related yet distinct chapters, each of which presents an account of particular thinkers, themes or debates in their historical context and in the light of today's concerns. The book is divided into three parts: Part One, Bishops and Authority; Part Two, Pluralism, Politics and History; and Part Three, Believing and Discipleship. It presents the fruit of a long period of theological research into different historical periods, but with a distinct focus on theology in the early twentieth century. Although each chapter can be read as history of theology, and each addresses historical debates in their own terms, at the same time each is concerned to relate historical issues to contemporary problems faced by the Anglican Communion and the Church of England today.
