As for scientific advancements it could be argued that it was the Catholic church that pushed most of the scientific advances in Europe, from monks to priest, from the discovery of the genetic code (Catholic Monk) to the establishment of the modern University system, the Catholic Church spearheaded this during "the dark ages".

That is a fact.
