I didn't accuse you of not providing a link. I accused the person you linked us to of not providing a link or any other authority to what she obviously (at least to me) copied and pasted. Any of us can put a bibliography at the end of our post and make it look really official.
I also pointed out the illogic of her thesis in that post in that it would lead one to believe that religion was a huge factor in manifestations of schizophrenia. But having a family member and also a close friend who suffers from this cruel disorder, I'm pretty sure whoever compiled that essay was either desperate to do a dissertation on something or they made it up. Though it is possible that religious delusions appear along with just about everything else one can think of, a comprehensive study of the disease doesn't back up what your link suggested.
If you go to Schizophrenia.com, which I believe is the most reliable, thorough, and comprehensive source for information, and poke around, you'll have a hard time locating any concern about religious influence. If religion is a significant factor in the cause, manifestation, or diagnosis of the condition, they sure seem to be unaware of it.

One interesting thing though is that you can read at this site that for those with the propensity for the disease, a dysfunctional family environment can increase the probability of developing the disease by 86%. Now we might want to look at whether those families who share a religious faith, worship together, and pray together are more or less dysfunctional than those who do not. And Schizophrenia.com sure recommends a lot of support groups who include significant religious faith in their programs.
