This work investigates how the proliferation of visual media transformed the practice and identity of American Protestantism between the nineteenth and twentieth centuries. David Morgan, a scholar of religion and visual culture, utilizes a vast archive of religious ephemera to argue that the rise of mass production technologies fundamentally altered the way believers interacted with their faith. By examining the intersection of commerce, technology, and theology, the author demonstrates that images became central, rather than peripheral, to the religious experience of the era.

Scholars frequently cite this work as a foundational text for understanding the intersection of material culture and American religious history. Experts highlight the author's ability to bridge the gap between art history and theological study through rigorous archival research.
