Konkordienformel
The Augustana Catholic Church accepted the Unaltered Augsburg Confession, the Apology of the Augsburg Confession, and Martin Luther's Small Catechism, but only insofar as they are in full agreement with Roman Catholic faith and order, doctrines, and traditions. The ACC recognizes the other documents contained in "The Book of Concord"—except for the Formula of Concord—but only insofar as they are in full agreement with Roman Catholic faith, order, doctrines and traditions. It did not accept the Formula of Concord on any level, nor did it consider itself bound by any of its terms and provisions, though it respected it as a historical Lutheran document.
