How is he putting himself out as the face of Christianity ?
Aren't Christians allowed to have many faces, one of which might be his ? He's not claiming to be the one and only interpretation in the article.
Although I am not a follower of his, I've seen his show occassionally on TBN, and he seems pretty regular. I've never seen anything to suggest that he's a false prophet or a heretic.
Do you have specific examples of heretical statements he's made; or is just appearing on TBN that earns that characterization from you ?
According to what I've read he is involved in the "Latter Rain" heresy as well as the Word of Faith movement. If you do a search on him I'm sure you'll find plenty of information about his "teachings".
I don't watch TBN because of it's line up of false prophets and faulty teachers. On the other hand, they have put on the likes of Ray Comfort, who teaches truth, but it's far more the exception than the rule.
