I never said priests/clergy didn't contribute to science, just that it was disingenuous to attribute things like the Scientific Method to the church. The Big Bang Theory isn't sacred, it just happens to be the theory that best fits our observations. If something came along tomorrow that fit BETTER, guess what would happen to the Big Bang Theory? Buh-bye!
Another thing about that: The Big Bang Theory (Any theory, really) isn't mine or "ours" (Hell, I'm not even a professional scientist). It belongs to the world and is currently our best explanation of the formation of the universe. Theories don't require blind faith. If someone doesn't believe in a theory, it doesn't make it any less true, only evidence can do that. Religion, on the other hand, does require faith. That's why nobody still practices Egyptian, Sumerian, Greek or any of the countless other dead religions that have existed through the years.
Your assertion that religion isn't afraid of science, hasn't always been the case, and in fact is only a very recent development out of need. Science has slowly been eroding god's domain over time, and so Christianity has had to adjust it's worldview to fit with society. Before that, when they actually had authority, the Christian church had a long history of persecuting, torturing and killing people who introduced ideas that were contrary to their all-knowing all-powerful scriptures. You have THAT kind of history with science, and then ask WHY science was afraid?
Christianity is LUCKY that the scientific community is rational and wouldn't think of treating Christians the same way that scientists have been treated at the hands of the Christian church, and would do well to remember that.
