In the gospels, Jesus performs various exorcisms including one on someone who is “demon possessed”. He casts out the demons from the man into a herd of pigs, and sends the pigs over a cliff.
As I understand it, Jesus seemed to believe that people suffered illness (mental and physical) because they were possessed by devils or demons. He acted as an exorcist to expel these demons from the victim and thereby cure them.
Do you think Jesus was mistaken in these beliefs? Did he misunderstand the reasons for illness?
