Thanks for the kind words. Is this as a Christian faith healer? If so, you may want to ask a Christian site since they may have more experience with this.
The main concern I'd haver is if he is hurting people. Are people refusing to get medical treatment because they believe themselves to be cured?
Also, are money and ego his main motives for doing this? You did not mention if he is making money doing this, but it's a question worth asking.
