Confessional Lutheranism is a name used by Lutherans to designate those who believe in the doctrines taught in the "Book of Concord" of 1580 (the Lutheran confessional documents) in their entirety. Confessional Lutherans maintain that faithfulness to the Book of Concord which is a summary of the teachings found in Scripture, requires attention to how that faith is actually being preached, taught, and put into practice. Confessional Lutherans believe that this is a vital part of their identity as Lutherans.
