Karl Adam illuminates the life and work of one of the most highly respected and widely read Catholic theologians of the 20th century - a theologian who not only influenced such diverse thinkers as Pope Paul VI, Karl Rahner, and Flannery O'Connor, but who also had a tremendous impact on Vatican II. Here Robert Anthony Krieg, CSC unites biography and theology in an analysis of Adam's most influential works, showing how he crafted a theology for his time, one that embodied the central tenets of Christian belief while simultaneously adopting the language of German neoromanticism. The book spans the century from Vatican I to Vatican II. Krieg begins by describing Adam's work against the backdrop of German Catholics' struggle to enter the cultural mainstream. He then analyzes Adam's major writings in the context of the Weimar Republic and the theological fermentation between the wars. Adam's confrontation with Nazism and his impact upon ecumenism and christology after World War II are also discussed. The last chapter appraises Adam's reliance on German neoromanticism for his "theology of life". Church leaders, historians, and theologians should appreciate this stimulating case study on catholicism and inculturation, which locates Adam's efforts at theological renewal in relation to both Rome's defensive stance against modernity, and also Berlin's nationalism during the Weimar Republic and the Third Reich.
