How did scientific rationalism affect religion?

I would say the second one, because it decreased the Church's reputation, more people started to believe in the science behind things rather than religion.

Overall, scientific rationalism harmed European religion because educated European people began to question the beliefs of the Catholic Church rather than just accepting centuries-old ideals, undermining certain fundamental beliefs of the Church and slightly decreasing its reputation.

Explanation:

During that time, the church's did not like science at all because it interfered with there religion, they even thought that, anyone who doesn't serve Christian religion, they would have to die, just because of not serving that religion. Be happy they don't do that no more, cus if they still did then you would probably be dead, not trying to offend you.
