Wes Morriston is awesome

Indeed. My first thoughts were of Immanuel Kant, who very famously argued against many of the traditional arguments for the existence of God, while still being a Christian.

He was? I was always under the impression that he was a deist...

I see from the wikipedia article that there is some disagreement on his views on religion:

My assessment of his views is based on reading various of his writings in which he mentions god and writes about religion.

Pay particular attention to this bit of the wikipedia article:

I am not very sympathetic to the view that he was not a Christian. Many Christians say that many other types of Christians who differ from themselves are not really Christians, so I don't take such claims too seriously.

If you are really interested in the question, I recommend that you start reading some Kant, though I don't expect the question to interest you enough to go to that much trouble (and with Kant, reading him is trouble, though not as much as some of the later German philosophers whose writings raise gobbledygook to extraordinary levels).
