English summary: This volume presents the proceedings of a conference held in 2015 at Humboldt University Berlin to celebrate the seventieth anniversary of the discovery of the Nag Hammadi Codices. The idea of the volume is to interpret the Nag Hammadi writings as part of the history of literature and theology of ancient Christianity. This approach articulates an aspect often neglected in research on these writings. In previous scholarship, the place of the Nag Hammadi writings within ancient Gnosticism was often discussed as was the relationship of several of these texts to the New Testament writings. This volume, however, takes a different view. The Nag Hammadi writings are analysed according to their literary genres (e.g. apocalypses, theological and philosophical treatises, gospels). Renowned scholars ask how these genres are realized in the Nag Hammadi tractates and how their place within the literature and theology of ancient Christianity can be determined. German description: Der vorliegende Band versammelt die Beitrage einer Tagung, die 2015 an der Humboldt-Universitat zu Berlin stattfand, dem Jahr, in dem sich der Fund der Nag-Hammadi-Codices zum 70. Mal jahrte. Die Perspektive des Bandes ist darauf gerichtet, die Nag-Hammadi-Schriften im Kontext der Literatur- und Theologiegeschichte des fruhen Christentums zu interpretieren. Damit wird ein bislang nur wenig beachteter Aspekt in den Vordergrund gestellt. Mit Beitragen von: Katrine Brix, Dylan M.
