My dear Badger please take a breath and re-read Slippery's post in its integrity
I think you are quite taking the quote out of its context. SlipperyJim stated clearly that he believes in building something great together despite of the differences of believing. Feeding the poor etc.
But you must accept that he (as his religion commands) believes in a somewhat invisible force that continues to live after s.o.'s death (belief that was born far before Christians and Jews, so not so strange... it was actually existing beyond Neanderthals, far before new earth creationists think the world was even born

but that's another story) and that this force must be preserved from evil after death - even the one of other ppl - as a moral duty. This leads him to believe that some teachings are as important, or even more important (counting for a literal "eternity"), than feeding those poor people - just live with it. But he never said feeding and helping poors is useless. The contrary.
Plz, don't ruin your nice words of mutual acceptance because of that. Slippery may have used words me and you don't like too much but I'm sure his intentions are good - and his efforts directed even in more "physical life" (we would call it "real life" maybe

) ways
Best wishes
PS also remind that Slippery doesn't represent an entire faith of religion - our friend is a self-proclaimed (as far as I understood) fundamentalist evangelical Christian, so extending his ideas (good or bad) to an entire community of believers should be done with great caution.
