The term "Evangelical Lutheran" refers to a branch of Christianity that combines elements of the Lutheran tradition with an emphasis on evangelism. It originated from the teachings of Martin Luther, a 16th-century reformer who sought to return to the core principles of the Christian faith, focusing on salvation through faith in Jesus Christ and the authority of the Bible. Evangelical Lutherans typically gather in congregations that emphasize community worship, education, and outreach. They celebrate the sacraments of Baptism and Holy Communion, viewing them as essential means of grace. This tradition is represented by various denominations, including the Evangelical Lutheran Church in America (ELCA) and the Lutheran Church—Missouri Synod (LCMS).
