Nice reply, thanks! Yes, I was being glib with that comment. It was in response to an openly hostile post, and I thought that was the best approach.
Interesting you say you weren't trying to correct me. Your question very much comes across as corrective; asking me to question my comment doesn't quite say "hey, here's some more information you may be interested in".
Belief is very much part of the organisation that is the Catholic church, or any religion, really. Their beliefs are set by their leaders and their founders, and taught by their clergy or denoted members. Of course, individuals also have beliefs, but they are generally guided by the organisation that they're a part of.
I'd actually argue that all organisations use belief in one way or another, and that a shared belief is often necessary for the construction of one.
Otherwise, definitely agree that Catholic, and Christian, people have had great influence over science. Being the dominant religion of the western world, it would have been very difficult for science history to progress otherwise.
