Pentecostalism
I don't think the host's assertion is very far off or ridiculous. I think he has a fair point. The prosperity gospel is a twisting or a misunderstanding of scripture and if prosperity gospel fellowships continue in these misunderstandings, I wouldn't be surprised to see it practice something different from traditional Christianity. While they could easily see their mistake and become more orthodox, I think it's more likely to continue in more misunderstanding of scripture which would lead to a different religion.
