If he is Southern Baptist, his doctrine is probably just fine. Also, I'm SB and that's the first time I've heard of that rule.
It's painful to watch FReepers make such fools of themselves over Rev. Graham.
You are not referring to BC, are you? As a sister SB I'm convinced that Billy just "got wet" when he was baptized... nothing more!
My comment was sort of tongue-in-cheek, but it's generally the case with all denominations. Those within one's own denomination is often considered "more" of a brother/sister than those of another denomination.
