That's not true, though.
Take the slavs for example.
Idon't know why this is called "revival" (maybe for Poles cause Russians have had "double faith" since forever) because, it has been with them since throughout the "Christianization".
Again "double faith" has been a thing for aages.
As for your
Thing.
Firstly, I cannot give you exact numbers on any of these, asking me to do that is ridiculous, but every one of them remains firmfly incompatible with Christian conquest and the purge of all "superstions" and the loss of "all customs"
Enough to keep it alive, obviously.
In Germany this seems to be tied to more rural areas, it's pretty high here.
We're not all vikangz, damnit.
Pagans"/"Asatruars"/"Heathens" etc. believe that when they die, that they go into the next realm to be with or be rejected by their family and ancestors based on the deeds in their life and continue to "live" in the land/mountain/hill they are buried, to be prayed and offered to by family members, rather than believing they are going to Valhalla, or to one of the halls of their personal favorite god (directly influenced by the concept of the Christian personal relationship with Jesus), or that the "gods" are nothing more than Jungian archetypes, or symbols of nature, or deified ancestors, or egregores that were prayed into existence because the people believed hard enough?
I have no idea.
How many Christians believe in superior Christian philosophies and teachings and would gladly remain Christian even if there was no heaven to go to in the afterlife?
Because I have the opinion that Christians do not care and merely want their soul back, in Heaven.
Also, why do you think that belief can be reduced to a magic formula that is uttered a bit like this:" I accept Jesus Christ as my savior!"
A magic incantation is not faith, by the way.
Nor is having a billion books explain everything about it. That's called instruction.
But that's just a sidenote.
Probably all of them. Prancing around a conquered land full of pious Christians with evil devil stuff can only be done by the most hardcore of believers.
I would tell you that your scope is incredibly narrow and that I know for sure that there are a lot of Europeans lamenting the loss of many clear roots of traditions and beliefs, because it's still important to them.
Also, it's pretty neat how easily you dismiss anything as "wimp lo" stuff.
Wooden ships have gone out of production, more or less, and I'm speaking SHIPs here, not a little fishing boat.
Up until very recently shipwrights would still use ash wood in ships because it was directly connected to water, it's a holy water tree.
And you know what else?
I'll turn your argument around on you and it will make perfect sense in my hands:
Even if all of it were bullshit. They still believed it and therefore still ACTED by putting ash wood into ships.
That's the crux.
You can laugh all you want, again, it changes nothing in reality.
But belief is belief is belief, and if we are talking faith in general here.
Having less to go on and still believing is more faith as having a gorillion books on it and STILL fracturing into umpteenth denominations even though it should all be a UNIFYING truth.
But yeah. Whatever, right?
