Ben, excuse my ad hominem in this case, but, after this long, multi-threaded, ongoing match at Wimbledon, I still think you are fantastic (and amusing). By the way, did you notice that the demon Simon ben Yoḥai is said to have driven out of the daughter of the Roman emperor was named Ben Temalion? I wonder who named him or if he, in the process of exorcism, identified himself by name. Anyway, the point is, at the time of Jesus, it apparently wasn't just Greeks who believed in demons as the cause, especially, of physical illness, so please let your character "Thomas" take note and alter his dialog in your Forbidden Gospel before you publish.
Always looking out for you,
Do you know something Serv, I consider the exorcist part in the Ministry of Jesus as part of the 80% of the NT which I take as anti-Jewish interpolations influenced by the Christian mind of the writers. We consider evil spirits as emanations, and emanations cannot be exorcized as if they were animated beings. Since Jesus was a Jewish man and never had anything to do with Christianity the idea must have crawled in by Hellenistic influence.
