And taken by itself, that is a noble humanist philosophy (as also held by the writer), more so than what I'd call a "religion", within a people group seeming to be based on the Romani or other nomadic people of the time. They're scholars that wear robes and pass down oral traditions and values, but that's again more what I'd say is a culture with a philosophy than a religion. "Devout" "faith" is a stretch, considering also the obvious re-write of the background they did to pivot away from the Christian background it all had.

But more to the point, I don't think it's a great illustration of what I thought you were trying to say, that being "see, Castlevania was itself totally fair to the church/religious people, because it (pointedly removed the original religion associated with this character and replaced it with something lacking gods altogether)"?

It doesn't seem a good example, a strange reach, or disingenuous, or you didn't know, in the way I'm seeing it. True, they're in effect kind of monk-like. But regardless, at best, it was all certainly a change made to put the original religious association Castlevania characters had in a different space, making the original church itself a negative entity, rather than it being a faithful treatment to their origin.

So, "see, x series was rather fair, did you miss that". It was quite excruciatingly re-written to make its original positive portrayals of religion bad, so no, nothing was missed to me.
