Well, it's a puzzler for sure. I'm an atheist; I regard myself as what Richard Dawkins might call a "Cultural Christian", but I sorta prefer the term "Christian Atheist". Personally I do not go to church, but I don't rip the head off people who do, and indeed that group would include a lot of my closest friends and family (theists and atheists alike). I recognise the historical legacy left by Christianity, even if the historical basis for the resurrection (that sine qua non of the whole shebang, according to a certain Saul Paulus) has been shown to be non-existent.
Deep down - or not even that deep - I do not feel that theism and a scientific outlook are compatible. I recognise that many scientists are theists, but that simply shows us that people can internally tolerate a disconnect, and that is hardly Big News. The reason for the incompatibility is not that science "disproves god" - I accept that it doesn't and indeed cannot absolutely rule out the existence of a goddy thing - it is much simpler than that.
Science cannot tolerate authority.
As a scientist, if the bible tells me that such-and-such happened at such-and-such a point in history, it may or may not be telling the truth, but the status of any such statement is that of a claim. These claims may or may not have supporting or contradictory evidence. I am in no position to accept them as true, and indeed I must (as a scientist) be at liberty to reject them if they conflict with the evidence.
Which is a problem for the Theistic Christian, because if we apply proper methods of historical analysis to the biblical claims, the scientific methodology behind archaeology, and the rational approach demanded by science, we find that events such as the virgin birth or the resurrection do not only not stack up, they are refuted by evidence from within the bible itself.
So how should we handle things when someone gets up in a pulpit or other public platform, and sounds off about some matter or other (such as homosexuality, for instance), using the bible as "authority", when ALL of us atheists, whether Christian or otherwise, REJECT that authority? Should we make an issue of it, and contradict the speaker, thereby causing tremulousness among those who demand "Christian unity", or should we simply accept it, smile benignly, let it pass, and privately internally pity the poor sap who is so deluded.
Good cop or bad cop?
I'll admit to playing both roles from time to time, but then I can afford to do so, since I don't have a church to be kicked out of. Any experiences anyone would like to share?
