I don't see anything wrong with the differently translated suttas that can't be put down to an evolving English language. As for your 'rocks & solar systems' I think it means aggregates as your link actually suggests.
You are preaching to the unconvertible, I am busily accumulating merit for my next 'existence'.
You are right in that people will always have different interpretations as is seen within Theravada today.
I was just wondering if anybody could envisage a 'fundamentalist Sutta/Vinaya' group ever sprouting up within Theravada or indeed has it already done so and they are just regarded as an oddity. A bit like the embarrassing relative who nobody likes to talk about but nobody has the nerve to tell them to bugger off.
