Jay P. Dolan's Catholic Revivalism: The American Experience, 1830–1900 details the history of the Catholic Church in America by showing that revivalism, traditionally viewed as a Protestant phenomenon, was also a central feature of Catholic life and activity in the 19th century. To cope with the widespread social disorganization caused by large numbers of Catholic immigrants, the Church sponsored parish missions during which famous preachers gave a series of emotional sermons aimed at calling sinners back to their God and their Church. Dolan documents the extent of Catholic revivalism, its European roots, and its success in reaching the working class.
