dracattack....what's this? oh yeah supereligion

That's supernatural and religion combined.
I can't believe I've resorted to English to avoid Chemistry. Epic fail.

Ummmmmm
well
We had how the novel portrays reiligion and superstition as separate things, whilst today we might view them as one in the same. Because of how we see it, it was hard to judge what was what in the story.
There's the obvious things like using garlic to ward off Dracula, and the blue flames supposing to signify the site of hidden gold. They're supernatural/stitious things.
And the obvious religious stuff like gender roles in men protecting the defenceless women, and holy commissions, also Quincey Morris sacrificing himself to save the world from evil, like our man Jesus.
But then, other stuff , apparently, was a bit more blurred. Like the use of the crucifix. Jonathan Harker originally dismisses the crucifix (or more specifically the rosary) as superstition. But then later on it becomes his only weapon and protection against the Count. Then, that also might be a distinction being made between the Anglican and Catholic Churches. The typically Anglican resort to Catholicism to save themselves.

Ok that's all. Back to...logical straightforward science.
