This is an interesting and important review of the development of Protestant thought and action during the Nineteenth Century and especially its impact upon the social and industrial life of America. It is valuable as a background to the problems which the church faces today, and for those interested in American church history it is a notable contribution. The book covers the period from 1828 to 1895. It points out how Protestantism used its powerful influence to sustain the status quo consistently until the last quarter of the Nineteenth Century. Then increasingly violent outbreaks of labor trouble shocked the churches and the nation out of its complacency and prepared the way for the development of the Social Gospel and its contribution to the progressive movement in the United States. This should interest students of the American social scene as well as Protestant churchmen.
