This research project includes a two-pronged approach to the patristic age. The primary focus is on patristic theology itself and devotes special attention to early Christian apologetics (from Aristides to Augustine) and the arguments that it put forward. Which arguments were developed and what status was attributed to them? The second branch of this research project concentrates on the reception of the Church Fathers in the early modern period. How were the Fathers (especially the second-century apologists, Cyprian, and Augustine) used and read in the different context of early modernity?
