Hi guys, forgive me for not reading through the previous 300-odd pages in this discussion but I'll put forward my 2 cents anyway...
I'm a fan of agnosticism. No one can prove difinatively either way that God does or does not exist. But I'll put emphasis on the latter for the purposes of this discussion. Atheists who snigger at believers for they're irrationality are IMO just as irrational as believers. Because no one can provide evidence of such a standard (granted there is circumstantial evidence) to prove God does or doesn't exist, afterall if they could this discussion would not exist.
But God's existence is irrelevant anyway. Whether He exists or not He is not making any material difference to the state the world is in now. In other words, we must live our lives assuming God doesn't exist because believing God will solve the worlds problems is illusory and, frankly, harmful. I'm reminded of JFK's conclusion to his inaggrual address: "with good conscience our only sure reward, with history the final judge of our deeds, let us go forth and lead the land we love, askinh His help and His blessing. But knowing that, here on earth, God's work must truly be our own." This is the attitude with which we should live our lives, no matter what your position on God's existence is.
We don't need oraganised religion either to seek either fulfillment or moral guidance. We are all endowed with a conscience and can decide for ourselves, with guidance from the community what is right and wrong without guidance from organised religion which I feel is ultimately restrictive. As far as fulfillment goes, religion certainly has its place, but many fill this void with other things such as sport or music. I personally pursue a completely irrationaly following of Arsenal, I'm horribly dissapointed when they lose and a win can make my day, experiencing a whole range of emotions in the course of a game which could otherwise take months in the course of my life. In this sense the following is religous.
Hypothetically speaking, If i could be convinced that God exists, I doubt I would turn to Christianity. Being most familiar with it of the major religions, I see its hypocrisies and irrelevences extremely clearly. The chief reason is that the Bible as a source is deeply flawed. As Paul took control of the early Church away from James in the years after Christ's death, he also took the right to write the Bible. Paul never met Jesus, James obviously had. From here on a number of chronicles of Jesus' life were written by a variety of people who never met him and some were selected seemingly at random by mortal beings to be apart of the Bible. Then as the church slowly developed I believe they became increasingly irrelevant and the Pope's recent declaration of these 7 extra deadly sins is a good example (anyone else pick up the intense irony of the Catholic Church denouncing wealth).
Ok there's a start, I might add more to this later but for now I've got Brave New World and Bladerunner to deal with...
