"I believe the schism between the two branches of Magesterialism was rather violent until they settled which was allowed to call itself 'Catholic', but both of them believe that the Magesterium in Geneva has divine authority, while the Byzantine Catholics do not. Rebaptists baptize people again as young adults, in case it matters whether they made a decision, and Solae Evangelists believe that only people's private interpretations of scripture matter for their salvation, rather than tradition or theological consensus?"

"I'm not gonna remember all that."

"That's fair. What distinguishes being Mormon from other kinds of Christianity?"

"Oh, uh, we have extra Scriptures is I guess the big one? And littler stuff like the coffee and tea thing. I think some kinds of Christians think we aren't because there's some thing that we don't think is exactly right that they think is a requirement for being a Christian but other than that we're obviously a kind of Christianity."

"If it does exist in my world, it's almost certainly on this continent, because extra scripture is illegally heterodox in Europe, but just discouraged in most of the countries here?"

"Oh. Mormonism started in the United States back when there were those. Joseph Smith founded the church after an angel told him some stuff."

"Neat! I'll need to research to find out if Mormonism exists or ever existed in my world when I return. I've been working on trying to experimentally prove the existence of angels."

"That's a funny sounding project."

"Yes, it wasn't my original plan, but I noticed some interference in the measurements for my main project with similar patterns to those recorded the last time angels were reportedly observed. –Have they figured out how to get pictures of angels to develop correctly in your world?"

"I... don't think people have tried taking pictures of angels. We don't see them that often."

"Oh. That's too bad. We've only had a few reported sightings in the last century, and it was mostly a matter of luck that the most recent, about twenty five years ago, was in a research chapel that was recoding measurements at the time."

"Wacky."

"Yeah. Unfortunately, most of the other details of the circumstances were censored, so there's only a little bit of data before and after it was there, and about half of the readings in the middle were redacted."

"Oh, how come?"

"They didn't release an explanation, but presumably the experimental-supervisor from the Magesterium decided that something in it might accidentally mislead or confuse a layman into believing something false, or heretical?"

"Sounds kinda Gileadite."

"Huh. The same region in my world was rather revolutionary for not requiring the supervisors. What's Gilead like, then?"

"They censor a lot of science and a little math because if they let people learn it they think it'll make them stop being Gileadite somehow."

"Weird! The Magesterium meaningfully censors maybe fifteen percent of theological and artistic works, and almost nothing from the other sciences. ...If their theories are contradicted by validly done math, wouldn't that just prove them false?"

"I don't really know a lot about it."

"Okay. It doesn't sound like a particularly good or useful system to spend the time to learn about."

"I was actually meaning to say I don't know much about math. Anyway, my church doesn't suppress any academic anything, there's some blockers on the internet so foreigners don't put porn on our computers but that's different."

"Oh. Well, good for your church. They got an internet working in your world? That's amazing!  –and people use it for porn? That seems like a waste; I'm glad they've figured out a setup to help avoid it."

"People use it for so much porn. You don't have an internet but you know what it is?"

"That's too bad. Yes, assuming it's an interconnected network of computers and ordinators, between many smaller networks, probably using something called 'packet switching'? My friend was closely following publications about developing an internet a few years ago, he'd hoped to join the International Computing Network project."
