Manichaeism and Early Christianity comprises the selected papers from the 2019 Pretoria Congress and Consultation. The sixteen chapters focus on where and how Gnostic Manichaeism interfered not only with other forms of Gnosticism, but above all with the writings and representatives of mainstream Christianity during the early centuries of our era. Key texts dealt with are a number of Nag Hammadi writings (including the Gospel of Thomas) as well as figures such as Marcion, Tatian, Ephrem the Syrian, Chrysostom, Pelagius and—not least—Augustine and his pupil Evodius.
