10 Crazy Little-Known Rules of Mormon Life

by Mark Oliver
fact checked by Jamie Frater

Nearly 15 million Mormons are spread across the world, yet the rest of the population seems to know little about them or their beliefs. They seem like wholesome people, but what are their lives actually like? What rules are the Mormons supposed to follow?

It’s a question worth asking because it turns out that there are quite a few rules—and some of them are a lot weirder than you might expect.

10 No Drinking Hot Drinks


While Christians are happy to go around turning water into wine and drinking until they pass out naked in tents like Noah, Mormon scriptures specifically forbid all the most dangerous substances: alcohol, tobacco, and drinks slightly warmer than room temperature.

Most of the time, this “no hot drinks” rule is interpreted as meaning “no coffee or tea.” That might make sense if it’s a rule against caffeine because caffeine is addictive.

But strangely, it’s not a rule against caffeine. The Mormon Church is totally fine with people consuming as much caffeine as they can handle—just as long as it’s slightly chilled. They have specifically stated that Coke, Pepsi, and any other form of caffeine is completely fine as long as it’s not heated.

9 Missionaries Can Only Play Half-Court Basketball

Mormon Missionary Ballers (ORIGINAL)

Mormon missionaries get all the weirdest rules. These are the people in the white dress shirts who come knocking on your door, wondering if you have time to talk about the Book of Mormon. They’re kind, cordial, and subject to some incredibly strange rules.

Like the one stating they can’t play basketball unless it’s a half-court game. Missionary rules are extremely explicit about this: Missionaries can’t play in leagues, in tournaments, or on a full-size, regulation basketball court. Even with half-court basketball, they’re not allowed to keep score.

So, if you ever get challenged to a game of ball by a missionary—which actually happens a lot—invite them out to a full-court and see how they react.

8 Missionaries Cannot Swim


Playing half-court basketball is actually a luxury for these missionaries. Almost every other sport is completely off-limits—especially swimming. According to the missionary handbook, they can “never go swimming.” Ever.

These rules aren’t completely insane. The Mormon Church is strongly against full-court basketball and playing Marco Polo in local swimming pools because they’re worried about injuries. However, some reports reveal that they can’t swim on Sundays. Swimming is usually done for recreation. The god has asked to spend one day of the week in worship, and recreation distracts them from goal. There is nothing evil about swimming. But they lose spiritual balance when they fill time with fun-seeking activities.

7 Missionaries Can Only Call Home Twice a Year


Historically, missionaries didn’t get to see their families, either. If they wanted to talk to them, they had to wait until Christmas because Mormon missionaries were only allowed to call home twice a year—on Christmas and Mother’s Day.

Those boys in white shirts who knock on your door weren’t allowed to do much else. They start working at 9:30 AM every day but Sunday and don’t stop until 9:30 PM. Everything else was considered to be a distraction—including their parents.

However, the church changed this rule in 2019, issuing a new policy that encouraged communication. Missionaries are now allowed to contact—via phone calls, email, and texts—every week. The church acknowledges that communication was an important part of their missionary service.

6 No Eating Meat in the Summer


Most Mormons don’t even know about this rule. Officially, Mormons are supposed to be almost entirely vegetarian. The Mormon scriptures clearly state that meat “should be used, only in times of winter, or of cold, or famine.”

Which is not what actually happens. If you invite a Mormon to a barbecue, he’ll probably eat as many burgers as anybody else there. But that doesn’t mean his family’s undergoing some terrible famine that he’s too polite to bring up. It’s just because, like the Bible’s “no wool-linen blends” rule in Deuteronomy 22:11, this one doesn’t get followed very often.

But it is definitely a rule. Major Mormon leader Brigham Young supported the rule and told his followers only to touch meat during famines. Nearly every other major Mormon leader has endorsed it too. So next time a Mormon friend drops by, pass him a veggie burger.

5 Keep Three Months’ Worth of Food Stockpiled at All Times


As proud as the Boy Scouts are of their “always be prepared” motto, they have nothing on the Mormons. The church tells its followers that they live in tumultuous times and need to be self-reliant for anything that comes—whether it’s the apocalypse or a personal tragedy.

Every church has an emergency response plan ready for its ward to keep the church members safe in the event of a catastrophe. The people are expected to be ready too. The church instructs every member to keep an emergency shelter ready with a three-month supply of the food they eat daily.

4 No Oral Sex


Originally, the Mormon faith was hardly the faith of prudes. Joseph Smith had 34 wives, and it’s generally assumed that they did more than play cribbage together. Over time, though, the religion started to change and, toward the 1970s, started getting tough on sexual immorality.

The church officially announced that oral sex was an “unnatural, impure, or unholy practice“—and that wasn’t just a rule for horny teens. Married husbands and wives were forbidden from keeping each other happy under the bedsheets in their private homes. They couldn’t even set foot inside a Mormon temple unless they repented and put an end to their twisted ways.

Mormons wouldn’t stand for this, and the oral sex rule got struck down within a few years.

3 Teens Must Pass a “Chastity” Test

Worthiness interviews in the Mormon church are designed to prepare children and teenagers spiritually and ensure they are obeying the commandments. They often start around a child’s eighth birthday, when Mormon children are baptized, and then again at 12. They are meant to be carried out at least annually into adulthood. However, current and former members of the Mormon Church are calling for an end to the practice of asking children as young as eight intimate and sexual questions during these annual interviews by church officials.

The most controversial element of the interviews relates to something known as “the law of chastity,” though some bishops choose not to ask questions about sex. In the church, sex outside of marriage, pornography, and masturbation are banned. The interviews are conducted in a closed room, one-on-one with an older male bishop, unless the child or teenager requests another person to be present.

The interviews have caused controversy in the U.S. and in the UK, and a campaign to stop the practice gained ground in the 2010s. There were some changes made to the rules where instead of five general topics to discuss, there are now 13 standard questions. One of which is “Do you live the law of chastity?” However, bishops are still directed to make “appropriate use” of the “standards and explanations” in a church pamphlet. And that leaves the door wide open for far-reaching, open-ended conversations about modesty, dating, media usage, and what the pamphlet calls “sexual purity.”

2 No Criticizing the Leadership

If a Mormon has a problem with any of these rules, he’s welcome to his opinion—as long as he keeps it to himself. A Mormon who writes articles or makes public statements against the church can get in a lot of trouble, and the church is ready to stop them.

The church has a committee called “The Strengthening Church Members Committee,” which is sort of like a Mormon version of the NSA. They spend all their time reviewing and keeping files on every church member – especially about everything the members write.

If a member is caught criticizing the leadership, the committee notifies their bishop, who must confront the person about it. They sit down and try to get the member to stay in line—or else. If a member doesn’t comply, they can pay for it in more ways than just being excommunicated. Allegedly, people have lost their jobs for speaking out against the church.

1 Lying Is Okay


Mormons can’t do much, really—except lie. They share the Ten Commandments with Christians, Muslims, and Jews. Still, that commandment about not giving false testimony doesn’t really hold the same ground in Mormonism that it does in the other religions.

At least one Mormon has claimed that Mormons are raised “with the idea that it’s okay to lie if it’s for a higher cause.” Not every Mormon agrees with this statement, but it may hold a grain of truth. Apparently, throughout the history of the church, it has been okay to lie to outsiders if it protects the church.

According to anthropologist Daymon Smith, this stemmed from fighting the government over polygamy. Early Mormons faced a lot of legal problems because of their marriage traditions. They lied so much to keep their communities safe that it just became a cultural habit.

So, there are a lot of things that Mormons can’t do. But at least, they have the freedom not to admit it.
