Book excerpt: August Hermann Francke described his conversion to Pietism in gripping terms that included intense spiritual struggle, weeping, falling to his knees, and a decisive moment in which his doubt suddenly disappeared and he was “overwhelmed as with a stream of joy.” His account came to exemplify Pietist conversion in the historical imagination around Pietism and religious awakening. Jonathan Strom’s new interpretation challenges the paradigmatic nature of Francke’s narrative and seeks to uncover the more varied, complex, and problematic character that conversion experiences posed for Pietists in the seventeenth and eighteenth centuries. Grounded in archival research, German Pietism and the Problem of Conversion traces the way that accounts of conversion developed and were disseminated among Pietists. Strom examines members’ relationship to the pious stories of the “last hours,” the growth of conversion narratives in popular Pietist periodicals, controversies over the Busskampf model of conversion, the Dargun revival movement, and the popular, if gruesome, genre of execution conversion narratives. Interrogating a wide variety of sources and examining nuance in the language used to define conversion throughout history, Strom explains how these experiences were received and why many Pietists had an uneasy relationship to conversions and the practice of narrating them. A learned, insightful work by one of the world’s leading scholars of Pietism, this volume sheds new light on Pietist conversion and the development of piety and modern evangelical narratives of religious experience.
