> I wonder if this is how the clergy felt once the vulgar were...

You meant the "vulgus". "Vulgar" has the same root, but a very different meaning.

This random thought is kinda disconnected from actual human history. "Not allowed to study Scripture" was not a thing: Illiteracy was. There were people that knew how to read and people who didn't, that's it.

I'm trying hard (and failing) to visualize your mental image.

"Dear Father: it looks like the Bible has been translated to English by my dear brothers up at the monastery. I'm sure you understand why I can no longer be a priest"

Remember that you're living in the actual earth timeline, not the 40k one.
