This excellent collection of essays marks the eightieth birthday of Jim Estes, a scholar renowned especially for his work on the reformer and church organiser Johannes Brenz, as well as for studies on figures including Luther, Melanchthon and Erasmus. The contributions to this volume, written by some of the most distinguished scholars of Reformation history, reflect very well the range of his interests. After two short personal reflections on Estes by Gow and McConica, as former student and collaborator respectively, the first main section is entitled ‘Friendship and Collaboration’. This includes articles by Scheible and Wengert on aspects of the relationship between Brenz and Melanchthon, Rummel on Capito and Erasmus, and contributions by Sebastiani and Karant-Nunn on Erasmus’ reputation and Erasmus as fund-raiser. ‘Reforming the People and the Church’ picks up one of the key aspects of Brenz's career highlighted by Estes, namely his role as author of the church order of Württemberg. Kuropka looks at educational reform in Jülich-Berg, Ehmer reconsiders the organisation of the church in Württemberg, Mentzer reflects on the same theme in the context of the French Reformed churches, Seidel Menchi surveys the varying treatment of a series of works by Erasmus and Luther in Italy, while Deutscher examines certain northern influences on Novarese preaching. ‘The Polemics of the Reformation’ leads on to episodes of conflict: Hendrix re-evaluates the debate between Luther and Erasmus, Nelson Burnett analyses Erasmus’ contributions to arguments over the eucharist, while Kolb examines Simon Musaeus’ ‘Three Kingdoms’. The confrontational theme is continued in the following section, ‘Catholic Opponents of Erasmus and Luther’: Fantazzi looks at Erasmus’ conflict with Agostino Stueco, Crane examines the earliest writings by Parisian theologians against Luther, while Grendler charts the growing animosity of the Jesuits towards Erasmus’ writings over the sixteenth and seventeenth centuries. A final section, ‘The Search for Religious Peace’, consists of one chapter, Dingel's comparative study of early modern religious peace agreements. In a sense this piece returns us to the earlier theme of friendship and collaboration, which not only underpinned so much of Estes's own work, but also provided the context from which this collection of essays has emerged. In both the quality of the contributions it contains, and the generosity of spirit with which it has been produced, this volume is a fitting tribute indeed to Jim Estes.
