This article focusses on Adolf Von Harnack's profound study of Marcion, a theologian of the second century. He was amongst other things fascinated by Marcion's view of the Old Testament. Marcion rejected the Old Testament because it depicted the creator-god as a mean figure who humiliated human beings. Jesus was in no way related to this god. He came from the good God who is described in the New Testament. Marcion compiled his own Bible which had no Old Testament and only a few books from the New Testament which he purged from all Jewish or Old Testament influence. According to Marcion the newness of the Christ event made the Old Testament superflous.
