In their studies of social Christianity, scholars of American religion have devoted critical attention to a group of theologically liberal pastors, primarily in the Northeast. Gary Scott Smith attempts to paint a more complete picture of the movement. Smith's ambitious and thorough study amply demonstrates how social Christianity--which included blacks, women, Southerners, and Westerners--worked to solve industrial, political, and urban problems, reduce racial discrimination, increase the status of women, curb drunkenness and prostitution, strengthen the family, upgrade public schools, and raise the quality of public health. In his analysis of the available scholarship and case studies of individuals, organizations, and campaigns central to the movement, Smith makes a convincing case that social Christianity was the most widespread, long-lasting, and influential religious social reform movement in American history.
