European Catholicism is just European mysticism/paganism with a veneer of Jesus on top.
Part of that is because making the peoples of Europe accept Christianity required synthesis of concepts and subversion of genre to slip it into the pagan mindset.
You had monk in Germanic territory rewriting biblical passages to take on a more saga-like feel.
This is why you have poems like Muspilli, which combined a Christian eschatological core with pagan themes. I recall there also being a poem about Jesus being presented as a great warrior who would be wielding a spear to face off Satan in the end of days.
In fact Revelation played a huge part in making the pagans sympathise with the religion, as it was a theme they all knew well. Great battles/struggles/destruction at the end of days followed by a rebirth of the world into a new age is an extremely ancient concept.
The proselytizing monks had to get creative and make their faith wrap itself around established local beliefs. This is why pretty much every holiday has a pre-christian celebration underneath it.

The Romantic movement was an attempt to push back against the rise of the machine men, but alas romanticism is lost on the grain peasant and thus the machine men came out on top. While we wish to believe that quality surpasses quantity, you will find that quantity has a quality of its own.
The fundamental problem is one of blood and spirit, the solution to which is eschatological.
