The decline of Calvinist orthodoxy worked an intellectual revolution in the minds of several million Americans during the period between the eighteen twenties and the eighteen forties. The social ferment of that generation produced a variety of effects including social perfectionism, theological liberalism, millennial sects, and new waves of revivalism. To multitudes of men and women a new earth seemed as close as a new heaven. Working hand in hand with the theological rebellion which insisted on the possibility of universal salvation and the actuality of great freedom for the will, social circumstance provided an environment rich in economic abundance and freedom for social experiment. America seemed so close to social perfection, religious salvation so near for so many, the inner and outer human worlds so plastic and pregnant with possibility, that the pursuit of either piety or social reformation promised spectacular results. The Mormons and other new sects with evangelical and millennial overtones absorbed many advocates of “the newness,” but an important minority regarded the old and the new sects as almost equally intolerable. It was not easy for these unchurched rebels to find a niche in American society; they inherited religious sensibilities which made them feel uncomfortable with both militantly secular social reformers and the scattered theological rebels who clung to the label of “Deist” or “Agnostic.”
