arguments of Catholic critics of Luther. The references to Luther's
works are to the St. Louis Edition; those to the Book of Concord, to the
People's Edition.

Authors must be modest, and as a rule they are. In the domain of
historical research there is rarely anything that is final. This
observation was forced upon the present writer with unusual power as the
rich contents of his subjects opened up to him during his study. He has
sought to be comprehensive, at least, as regards essential facts, in
every chapter; he does not claim that his presentation is final. He
hopes that it may stimulate further research.

This book is frankly polemical. It had to be, or there would have been
no need of writing it. It seeks to meet both the assertions and the
spirit of Luther's Catholic critics. A review ought to be a mirror, and
mirrors must reflect. But there is no malice in the author's effort.
