Re: Leap of faith
"what matters to most members of a religion is the community, not the theology"
I have seen no evidence to suggest that at all.
Why build the big towers pointing to the man in the sky then? or all the images and statues of the supposed miracles and messiah? Why pray/sing to God when people get married in church? Why have "thanksgiving" as someone else pointed out, thanking whom?
What you've said it not true at all. If someone said "I am religious but don't believe in God (or A God)" they'd be laughed out of church or the equivalent (if they were lucky).
