When he said "religions" he must have mean't "scientists"
Once upon a time you could argue that most "scientists" were either of a church or mosque or supported by such an institution, for example Gregor Mendel is generally described as both a scientist and as an Augustinian friar.
Cathedrals didn't build themselves or innovate their own designs; contemplating the natural wonders was once considered equivalent to looking upon the works of God.
I'm not religious, my passions are science, mathematics, history (, and the Oxford comma); the narrative that "Religion Hates Science" has as much depth as spelling Microsoft with a $ or describing Americans as sheeple.

The Catholics were extremely hostile towards forks in religion - Heresy got you the full weight of the ban hammer. Christians were a fairly broad group, larger than just the Roman Catholics.
As for Galileo, he wasn't a religion he was a man and some other men (including one Pope more than the other Pope) really didn't like him. This wasn't so much Christianity or more specifically Roman Catholicism, being opposed to Science, more some people in power not likely someone they regarded as a disagreeable dick. There were supporters of heliocentric models within the church at the time, supporters of Galileo were harder to come by.
