In this important volume, Claus Arnold and Johannes Wischmeyer gather together a great set of essays that provides a glimpse into the variety of institutional and social factors affecting theological discussions going on internationally and ecumenically during the nineteenth and twentieth centuries. Space does not permit a full exposition of each essay, but a few notable contributions are worth highlighting. For instance, Klaus Unterburger draws upon his excellent earlier research to sketch the impact of German Protestant theology on the papal magisterium and the German Catholic Theology Faculty in light of the Apostolic Constitution, Deus scientiarum Dominus (1931). Elias Füllenbach narrates the history of the intellectual engagement in Dominican houses of study during the Modernist controversy in Europe, England and abroad to provide a helpful backdrop to the story of Nouvelle Théologie leading up to the Second Vatican Council. Thomas Howard surveys the ecumenical legacy of the Bonn conferences (1874–5) to complicate overly-precise narratives of secularisation in the nineteenth century. Leonard Hell provides a portrait of French and German Catholic relations during Second World War, highlighting the particular contributions Johann Adam Möhler and Yves Congar. Peter Walter offers a very helpful overview of the salient features and protagonists of Italian and German neo-Scholasticism. Finally, Benjamin Dahlke briefly traces the ‘Jesus of history’ and the ‘Christ of faith’ debates up until the late twentieth century with John Hick's Myth of God incarnate. This volume underscores the crucial role that religious orders played in the process of translation, publishing and archiving important theological texts. It also reconstructs the intellectual networks involved in key debates, shedding new light on how we read the development of modern theology today. Research libraries and universities will benefit greatly by adding this volume to their collection.
