'What makes Posset's book worth reading for the historian is not only his thorough analysis of Staupitz's theology and concepts of reform concepts, but also the detailed documentation of Staupitz' s close involvement in the early Reformation process.' H-Net Reviews '... fills a huge gap in Anglophone literature on the early Reformation and Catholic Reformation. It serves all scholars by systematically exploring Staupitz's writings and recorded sermons and by challenging the prevailing view of Staupitz as a 'fore-runner' of the Reformation.' Renaissance and Reformation '... a rich and stimulating English-language monograph that looks at Staupitz the preacher on his own terms.' Sixteenth Century Journal 'It should be placed on the reading lists of Reformation courses for both graduate and upper-division undergraduates, not just for its adjusted appraisal of Staupitz's importance, but also for the rich picture it paints of the German religious situation in the early sixteenth century.' American Benedictive Review '... all those interested in late medieval and Reformation thought will certainly profit from the extensive research and minute examination of Luther's mentor that have created this book.' Religious Studies Review '... I highly recommend the book. For the English-speaking world it is unrivaled. Younger scholars in particular will appreciate the work: it not only includes several useful translations of Staupitz's writings but also a nearly complete bibiography of relevant sources.' Archiv für Reformationsgeschichte '... an important contribution to Reformation history, not least because it sees beyond the oversimplification of imagining that a decaying Catholic church led to the birth of a protestant alternative to grasp the truth that roots of the Reformation are to be found in the Catholic tradition...' Revue d'histoire écclesiastique '... both useful and stimulating... Posset's book makes a useful contribution to English-language scholarship on Staupitz...' Journal of Ecclesiastical History
