Eric Gritsch's unique and ambitious work, the first-ever attempt at a history of global Lutheranism, is now in a new edition.In a clear, nontechnical way, this noted Reformation historian tells the story of how the nascent reforming and confessional movement sparked and led by Martin Luther survived its first battles with religious and political authorities to become institutionalized in its religious practices and teachings. Gritsch then traces the emergence of genuine consensus at the end of the sixteenth century, followed by the age of Lutheran Orthodoxy, the great Pietist reaction, Lutheranism's growing diversification during the Industrial Revolution, its North American expansion, and its increasingly global and ecumenical ventures in the last century.From Wittenberg to Tanzania, from Spalatin to Spener to Schmucker, Gritsch tells the story with clarity and verve. This new edition updates all the chapters with fresh research, adds a chapter on new global developments and issues, and adds a rich array of graphics and other teaching tools.
