I was asked by the Society to provide an introduction to current historical thinking about the English Reformation in the first talk to the 1995 Conference. The ensuing lecture was deliberately intended to provide guidance through the minefield of controversy about the success of Reformation for those with only limited knowledge of sixteenth-century history. Debates about the Reformation have always been of obvious importance to both theologians and historians: they have usually in the past been profoundly influenced by confessional ideologies. In the last thirty years the nature of the questions asked about Reformation has undergone marked change: specifically the issue of popular religious belief and practice has assumed a centrality it never before possessed. But new questions have not brought closer agreement on the nature of religious change, and in recent years fierce debate has continued to rage on such issues as the vitality of late medieval Catholicism, the popularity of the early reformers and the motives of Henry VIII and his successors. Some, at least, of these controversies are still bound up with Protestant, Catholic and Anglican identities in the late twentieth century. Since the continuities between past and present were the theme of last year's Conference, I have touched on these identities, but have left it to others, especially Dr Rowell and Dr Rex to make these connections more explicit.
