This book investigates the intersection of institutional religion and folk belief systems among the working-class population of Southwark, London, during the late nineteenth and early twentieth centuries. S. C. Williams utilizes archival records and local historical data to challenge the assumption that urbanization led to the inevitable decline of religious sentiment. The author argues that residents actively reinterpreted orthodox doctrines to align with their own cultural values, creating a unique hybrid of urban popular religion that persisted well into the twentieth century.

Historians and sociologists frequently cite this work as a significant contribution to the study of urban secularization and cultural adaptation. Experts highlight the text for its rigorous archival research and its ability to provide a nuanced view of working-class religious identity in industrial London.
