the more interesting question is how are they able to prop up such nonsense? same here, how/why do christians cling to the primacy of jesus thing?
Jesus, Near-Death Experiences, and Religion
Religious Figures In NDEs, Especially Jesus & Muhammad
Bottom line: Setting aside the dark, shallow, uninformed, uninspired, and grievously misaligned history of Christianity that took root after Jesus left, there is, I think, something about Jesus (and his life and teachings) that deserves special attention. And special respect. I also think we should be careful to separate Christianity from Jesus, especially the kind of Christianity that was/is promoted by Rome and Christian fundamentalists.
