While the premises may have been superstitious craziness, the Christian Church in the West developed an astonishingly successful and huge range of social institutions. I believe this infrastructure has been a huge driver of our political and economic dominance in the last 500 years. Even the science that is overthrowing religious superstition would not have been possible without Church supported universities and general education.
Also, as a social service bureaucrat, my job would have been within a religious organization until 1875 or so. And probably better executed than under modern "scientific" paradigms.
I just hope we throw out the baby but keep the bathwater...
