Hauntings, Exorcisms and the Like

my brother has a class with an elderly guy who had an interesting religous journey.he started as a new-ager (back when there were such things) and was confronted with a demonic spirit. he then turned to catholicism since that was the easy solution to fight demons. after some years as an exorcist, he confronted demons in his superiors in the church and left it to become a zoroastrian. (nearly identical to christianity but with different names and such). he's apparently really cool.
