This festschrift unites exegetical and research-historical studies on early Christianity and the religio-historical school written by colleagues, coworkers and former students of Gerd Lüdemann from Germany, Scandinavia, the United States and Japan. The spectrum of topics is broad, and they stem from the many fields of interests Lüdemann has written about – the exegesis of the New Testament, the reconstruction of the history of early Christianity as well as research on the influential religio-historical school of thought.
