I believe in God but I'm not married to any particular religion theologically. If I have to define my beliefs, I'd say I am a theist. I think God leaves us alone for the most part so as not to tamper with free will, which I see as the most vital component of the God/man relationship.
I was raised Catholic and though I do not practice, I'm okay with identifying myself as such because I believe Catholicism is as much cultural as religious. In addition, I think all major religions have a healthy mix of sincerity and flaw, so I don't feel that on the rare occasion I attend church that my choice of a Catholic church requires that I fully subscribe to its dogma or that I defend its moral lapses.
Finally, I believe in evolution and I don't see any conflict between the discoveries of science and the existence of God. I think that creationists and fundamentalists give Christianity a bad name.
