Lutheran Church originated from Martin Luther’s 16th-century Protestant Reformation, emphasizing salvation by grace through faith alone. Lutherans maintain a liturgical worship tradition centered on Word and Sacrament, particularly baptism and communion where they hold to Christ’s real presence. Lutheran theology is guided by the Book of Concord, a collection of confessional documents. Different Lutheran bodies range from conservative (Missouri Synod, Wisconsin Synod) to more progressive (Evangelical Lutheran Church in America). Their governance varies from congregational to episcopal models, while maintaining Luther’s emphasis on the priesthood of all believers alongside ordained ministry.
