The first of the chronological volumes in this acclaimed critical edition of Bonhoeffer's work gathers his one hundred earliest letters and journals from after the First World War through his graduation from Berlin University. It also contains his early theological writings up to his dissertation. These seventeen works include, for example, works on the patristic period for Adolf von Harnack, on Luther's moods for Karl Holl, on biblical interpretation for Professor Reinhold Seeberg, as well as essays on the church and eschatology, reason and revelation, Job, John, and even joy. Rounding out this picture of Bonhoeffer's nascent theology are his sermons from the period, along with his lectures on homiletics, catechesis, and practical theology.In translation for the first time, these writings show Bonhoeffer as pastor and theologian alert to his times and developing the formative themes of his religious worldview.
