Jonathan Edwards (1703-1758) is widely regarded as North America's most influential theologian. Throughout the early decades of his ministry he engaged in a public and sustained debate with 'Arminian' theology, a crusade that contributed significantly to the events of the Great Awakening. This book investigates the contours and substance of this theological war. In establishing a clearer historical context for this polemic, McClenahan seeks to overturn the scholarly consensus that Edwards' own theology was a twisting of the Reformed tradition. By demonstrating that Edwards' interlocutor was the dead English Archbishop, John Tillotson, McClenahan provides the hermeneutical key for many of Edwards' most significant works. Justification by faith is one of the most contested doctrines in contemporary theology and Jonathan Edwards, referred to as America's Augustine, wrote extensively on this area. His is a voice that many people are keen to hear.
