Informally, yeah, sometimes they individually help someone out, buy them groceries, cut fire wood, that kinda thing just from what I heard in person and on here. But formally, no, they don't do much of anything beyond teach a few people to read and write so they can convert them, and maybe repair a roof or two after a disaster, but sometimes they ask for the insurance money afterwards, from what I've read on here, which I gotta say is pretty... sleazy, I think that's the right word.
It's an isolated, isolating faith. That's what it is. They care about their own, sorta, and write the rest of us off. That comes across very clearly.
