On the Ministry of Exorcism

I am in a seriously contemplative state regarding the ministry of exorcism this evening. It is a subject that very few people are willing to confront, much less address with any degree of the seriousness with which it is deserving.

At what point...?

So I am sitting there with a coworker discussing her daughter's illness which has gone on now for over a month. She has been to specialists, had X-rays, CATscans, MRI's, and blood testes. She has met with the child's teachers and there is no indication of anything being wrong at school. The child is aware that she is sick, but doesn't know why either. The only thing left (other than taking her to see Dr. House) is a psychiatrist.
So the though pops into my head "At what point does one advise a friend of the possibility of demonic possession and to seek the council of a Priest.?" Hmm...
