One that comes to mind is that medieval monks, as part of their duties, would copy older manuscripts, which had the effect of saving some classical works from destruction. Lucretius' De Rerum Natura is one example, the rediscovery of which is detailed in Stephen Greenblatt's recent book, The Swerve. Now, this wasn't the intention of the monks, rather more of an unintended side effect, but there it is.

Regarding intentional examples, it's a bit more difficult- as you mentioned, this is an incredibly broad question. In terms of 'progress', one would hardly pick the Church as an example of a progressive institution, and it would certainly be easier to pick instances of religious opposition to scientific advancement than vice versa. 'Success' is yet more nebulous- you could certainly include 'keeping people alive/less badly off than otherwise' in there, and in that regard many religions have a long history, in terms of running hospitals, orphanages, soup kitchens, and the like. The Salvation Army, for example, is a Christian organization, and there are plenty of others of its ilk.

Out of curiosity, is this a homework question? This seems like a question with an agenda, and it's either that or some sort of religious debate.

Sorry, we don't allow throughout history questions.
