I don't really mind it coming across as patronising. I'm an atheist, and resolutely live my life according to principles of decency and tolerance to others. Sure, I don't believe in heaven, and do I care what the Pope says will happen to me when I die? Not a jot. But if he's ultimately being nice to me, then who am I to throw that back at him.
He's like the old lady next door who baked me a completely inedible 'casserole' and left it in a tupperware container outside my door. Honestly, it was an odd thing, but it was done with nothing other than good intentions, so I was enormously thankful to her. So cheers to the Pope, I won't be taking advantage of your fantasy land, but thanks for thinking of me anyway.
