The point is that religion is based on faith, and it's impossible to prove by our current standards. I'm not talking about some priests claim to be all-knowing, where as other priests encourage to read religious texts for yourself.
Not sure what you're trying to say, but nobody's saying there isn't hubris and arrogance among scientists.
Ignorant people blindly believing in something is a problem, but that doesn't damage the integrity of science. At any rate, it's better that they mindlessly follow global, expert scientists, than leaders that would reject science to gain power and money for themselves.
