American Protestantism has been the dominant form of Christianity in United States since the colonial era and has had a profound impact on American society. Understanding this religious tradition is, thus, crucial to understanding American culture. This Companion offers a comprehensive overview of  American Protestantism. It considers all its major streams—Anglican, Reformed, Lutheran, Anabaptist, Baptist, Stone-Campbell, Methodist, Holiness, and Pentecostal. Written from various disciplinary perspectives, including history, theology, liturgics, and religious studies, it explores the beliefs and practices around which American Protestant life has revolved. The volume also provides a chronological overview of the tradition's entire history, addresses its prominent theological and sociological features, and explores its numerous intersections with American culture. Aimed at undergraduate and graduate students, as well as an interested general audience, this Companion will be useful both for insiders and outsiders to the American Protestant tradition.
