Uhm, this seems like saying that "eternal suffering for non-believers" is the mainstream position... it's just that People of the Book are not automatically included among the "non-believers".
That's one way of looking at it, I suppose. I think "non-believers" normally means "people who don't believe in that religion." Remember the original question was - how can an Abrahamic religion co-exist with a different religion? These are clearly different religions. I do think I'm drawing a meaningful distinction in that Christians believe that the only way to heaven is through Jesus (John 14:6, perhaps the most famous verse in the NT) whereas Islam teaches that you don't have to be a Muslim to go to heaven.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
