In the sea of Luther studies, this volume stands out as one of the best available in English. It is a condensed retrospective of the most significant Reformation research of the last decade, and it is clearly written with verve, insight, and humor. -- CHOICE Gritsch has provided us with a full-scale, one-volume biography of Luther. The work is meticulously documented and the bibliography at the end will alone warrant the price of the book. -- Roland H. Bainton This book will be an invaluable source of information for students of the Lutheran Reformation. Ecumenists will find in its pages a great resource in their efforts to deal with issues that have been church - divisive. -- Carl J. Peter, Catholic University of America
