Why does change have to be a bad thing?
The only argument is the speed of the change - the stars change over such a period as to be un-noticable oveer a human lifetime.
The christians call their god a constant - he is not - what he was, what he is, what his son was and what his son is, and what they both stand for is being changed year on year as the church finds that more and more people are rejecting the old proscriptions and values like tattoo's, like same-sex relationships, like homosexuality.
The values of christians have changed more in the last ten years than in the prevuous couple of hundred - in that time the stars have changed, to all intents and purposes, not at all.
