Modern Pentecostalism in America began around the turn of the twentieth century, and most historians of this history have drawn from the available English-language sources. Very few historians of American Pentecostalism knew of source materials in the Scandinavian languages of Norwegian and Swedish. This present volume argues that American Pentecostal history cannot be understood apart from both the texts and the people who participated in and contributed to the Pentecostal movement in America, including first-generation immigrants from Scandinavia and second-generation Scandinavian-Americans. Revising Pentecostal History describes ways in which Scandinavian-Americans have contributed to and played a role in the development of the Pentecostal movement. The volume presents crucial findings from rarely, if ever, used sources that inform how American Pentecostalism is understood. These findings prompt a revising of Pentecostal history.
