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.
