Confessional Lutheranism is a name used by
Lutherans to designate those who accept the doctrines taught in the
Book of Concord of 1580 (the Lutheran confessional documents) in their entirety because (
quia) they are completely faithful to the teachings of the
Bible. While most Lutheran denominations find the basis of their faith in the
Book of Concord, Confessional Lutherans maintain that faithfulness to it 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.
