This rare masterpiece is a 17th-century Lutheran dogmatics work to which C. F. W. Walther, first president of the Lutheran Church-Missouri Synod, added copious quotations from Luther and orthodox Lutheran theologians such as Martin Chemnitz and Johann Gerhard. This work was used as the systematic theology textbook at Concordia Seminary, St. Louis for many years, and was the basis for Francis Pieper's well-known Christian Dogmatics. In Latin and German (modern typeface).
