I think you mean "Pope Urban VIII's beef with Galileo...", not Cassini.
For what it's worth, Galileo made two critical observations with his telescope - specifically, his discoveries of the Jovian moons and the phases of Venus. The former demonstrated that the universe contained more than one center of gravity. This served as a fundamental contradiction of the Aristotelian metaphysics that anchored the Ptolemaic scheme, and which the Church had, by then, adopted as canonical. The latter phenomena made no sense in the context of a terracentric cosmos, but was perfectly consistent with a heliocentric model.
In other words, Galileo was not "saying that he was right and everyone else was wrong and they should just believe him because he was right." Rather, he was offering observational proof of the Copernican theory. His own theories about gravity, and specifically, WHY there could be multiple centers were - at this stage - irrelevant. The mere fact of these other centers' existence was enough to upset the intellectual status quo.
Indeed, the real bone of contention had nothing to do with the Church insisting on evidence in support of theory. The evidence was right in front of them. The problem was the inconsistency formed between the the revelation that Earth is a orbiting planet, and the (repeated) Biblical assertions that it wasn't. For instance, “He has fixed the earth firm, immovable.” (1 Chronicles 16:30), “Thou hast fixed the earth immovable and firm ...” (Psalm 93:1), “He has fixed the earth firm, immovable ...” (Psalm 96:10), “...who made the earth and fashioned it, and himself fixed it fast...” (Isaiah 45:18), etc. The obvious solution - a concession that the Bible made heavy use of metaphor, and should not be taken literally - presented intractable political problems for an institution that had amassed formidable power around interpretations that treated large amounts of the Bible as actual history.
Really, the notion that "the church was on the side of the scientific method" could not be further from the truth - not least of all because the scientific method depends on the freedom of consciousness, and the ability to change one's mind based on observable reality - regardless of contrary views based on scripture, fiat, or tradition. This degree of liberty was - quite literally - anathema to an institution that claimed something approaching a property right in the laity's souls. To say they were supporting it is flatly absurd.
You're telling this as if the rules for knowledge and deduction had already been worked out -- you're telling it in a way where we are invited to take our current understanding of how science works and drop it willy-nilly into a time many hundreds of years ago. It doesn't work like that. To them, holy writ was another form of valid observational data. The struggle religion is having is an internal one -- how literally to take the holy words. Offenses to science are just collateral damage in that larger debate. There was also a personal thing going on between Galileo and the Pope.
I don't say that as an apologist. I really feel like there is nothing to defend here. Mankind's belief system impeded and advanced the acquisition of scientific knowledge in various ways. For instance, I'd argue that the reformation was the biggest thing to happen to science, encouraging individuals to see and prove things for themselves.
I was just taking issue with not having enough context. Yes, the big picture is Galileo had a hard time of it. But all the little details -- the personality issues, the issues of evidence, the way his work was constructed, the way knowledge was generally gathered and advancements made at the time, etc. -- to me those are the juiciest parts of the story. Gives it a wonderful 3-D feel. To tell it like a comic book from the 21st century where the church is evil and Galileo was some kind of uber-hero is to commit a crime against the joy of history, in my opinion. It's a much more enjoyable story than that, and I'm not sure the listener of the comic book version really understands what was going on from this version of the telling. To be more blunt, and speaking as an agnostic and non-religious person, it sounds a bit more like anti-church propaganda instead of an honest look at how people lived. Listening to the apologist doesn't put me on the church's side by any means, but it sure makes the whole thing into a hell of a better story.
@Daniel - I hope you weren't expecting Galileo's full biography, a comprehensive survey of 16th century intellectual life, along with a dissection of approaches to the accumulation of knowledge that had developed over the previous, say, 2,000 years - all packed into a single HN comment. Context - remember?
