A lot of work went into reconciling religion (and the rest of society really) with the “science” of the time.

It’s one of the reasons why the scientific revolution was so jarring for all of society - it threw thousands of years of convergent philosophy across society into a paradigm shift when we were forced to abandon things like the 4 element theory.
