Book excerpt: This is a study on Reformed theological debates during the »Long Eighteenth Century« in Britain and New England. By »Long« a period that goes beyond 1700–1799 is in view. This examination begins just before the eighteenth century by looking at the Neonomian-Antinomian debate in the 1690s. This is followed by the Marrow Controversy in Scotland in the eighteenth century. After that, the authors address the ecclesiological debates between George Whitefield and the Erskines. The doctrine of free choice concerning Edwards and his departure from classical Reformed orthodoxy is highlighted next, followed by reflections on the Edwardseans and the atonement. Returning to Britain again, the volume provides a study on hyper-Calvinism, and on eschatological differences among key figures in the eighteenth century. More specific debates in particular Baptist circles are noted, including the battle over Sandemandianism and the Trinitarian battles fought by Andrew Fuller and others. Returning to ecclesiology, a discussion on the subscription controversy in Philadelphia in the early eighteenth century and an analysis of the debate about the nature of »revival« in New England close this volume.
