The first roughly 90 pages offer a brief but astute biography of Martin Luther. The remainder surveys various aspects of Luther's thought and the state of Luther research (at the time of writing). These varied in interest to me, largely because I am neither in the tradition of Luther or the author. I will note that the chapter on Luther and the Jews (The Gospel and Israel) was particularly helpful and maintained an exemplary scholarly distance. But I am Gritsch's student and not his master. While Luther has long been a keen interest of mine, and while I have surveyed his life in my own teaching and study several times (at least to the Diet of Worms, whereafter many in the Protestant tradition begin to part company with him), I am no Luther scholar. In fact, to my recollection, for all the reading on Luther I have done, this is embarrassingly the first complete biography I have read of the man. Bainton's commendation of this book is higher praise than I could give it: "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." While I am unlikely to ever return to read the bibliography, I am glad to know that it would be worth at least $4 to me. But I am sure that 30-40 years has far advanced the state of Luther studies. I knew this going into it. Why bother with an aged biography? Because the old need hardly be inferior, as the enduring popularity and general respect for Bainton's own 1950 biography attests, or the magisterial work of Gritsch's nearer contemporary Martin Brecht, or also of the 1980s, Kittelson or Oberman. None of these have I read completely (made a valiant run at Bainton not too long ago), but baby steps and all that. As for the new, I would certainly like to read a few. But better to be old and reputable than anything by Eric Metaxas.
