My point is that there's no real evidence supporting this conclusion. On the contrary, up until the 18th century nearly any scientific advancement in the Western world was either funded or directly done by the Catholic Church. The idea that the Church actively opposed scientific findings which didn't agree with their world view is, for the most part, a myth. Even its famous falling out with Galileo Galilei is more due to a personal dispute between him and Pope Urban VIII (who initially supported Galileo) rather than his theories.
The Catholic Church has the great advantage that they don't adhere to Biblical literarism, so there's no initial conflict between them and science. Indeed, Pope Leo XIII wrote in 1893 that "no real disagreement can exist between the theologian and the scientist provided each keeps within his own limits". If you're really interested in this subject, Thomas E. Woods wrote an
excellent book about it. Or you could read the Wikipedia entry on the
Catholic Church and science.
