"This felicitous translation by James L. Schaaf...recounts with precise and telling detail the story of Luther's development to the Diet of Worms...Brecht's work long will remain a basic book on Luther's progress to 1521. It is thorough, reliable, clearly written, divided into manageable segments, and convincing in the total picture that he gives of the great reformer."
Lewis W. Spitz
"Brecht's scholarship is impeccable and his book is indeed original. He displays a remarkable talent for precision and conciseness of statement."
David W. Lotz
