Every October the same fight breaks out: Halloween is either a pagan festival of the dead that Christians must shun, or a harmless night of costumes and candy. The history says both camps are telling it wrong — and the porch light tells you the rest.

Allie Beth Stuckey, who hosts the “Relatable” podcast and has a large following among conservative Christians, took up the subject on her show this month. Her answer on Halloween itself wasn’t stay-home-with-the-lights-off — she laid out four ways a Christian can handle the holiday and picked partial participation, the kind aimed at sharing the gospel. But on fear she drew a hard line: Christians shouldn’t be fans of horror, she said — not the movies, not the scary books, not the true-crime podcasts — because the Bible says “do not fear” over and over, and paying for content designed to scare you is a direct contradiction of it. She’s not alone in it; she says out loud, every October, what a whole camp of Christians believes. Even Matt Walsh pushed back on her — he thinks supernatural horror is often subtly Christian — so the stay-away camp can’t even agree with itself. I just finished writing a post here about whether the Bible forbids horror movies, and my answer was no. So let me take up the calendar-sized version of the same question: should Christians celebrate Halloween?

The avoidance case usually starts with history. Halloween, you’re told, is really Samhain, an ancient Celtic festival of the dead — some versions say of demons and human sacrifice — thinly disguised with candy. Christians who celebrate it are, knowingly or not, keeping a pagan devil festival. That’s the claim. So before the theology, let’s check the story, because the story is doing most of the work.

Samhain is real, but it’s not what the pamphlets say. It’s first attested around the tenth century, as an Irish seasonal marker for the onset of winter — the end of the harvest, the turning of the year. The “great festival of the dead” version comes mainly from Sir James Frazer, the Victorian armchair anthropologist, and the modern historian Ronald Hutton, who actually went through Frazer’s evidence, delivered a verdict every blogger should envy for its bluntness: the evidence is “utterly wanting” and the chain of reasoning “completely breaks down.” There is no record of Samhain being dedicated to the dead, to demons, or to ritual evil. And there’s a simpler problem with the “devil festival” label: the ancient Celts didn’t have a devil. The devil is a Christian character. A Satanic Samhain is an anachronism twice over — once for the date, once for the cast.

But if the “pagan origins” story outruns the evidence, so does the mirror-image story told by the other side: that the church invented All Saints’ Day to steal Samhain and rebrand it. The church’s own paper trail says otherwise. All Saints began in Rome on May 13, 609, when Pope Boniface IV rededicated the Pantheon to Mary and all the martyrs — in May, nowhere near November. Pope Gregory III moved the feast to November 1 in the eighth century; by around 800, churches in England and Germany were already keeping it on that date; a later pope made it universal. Halloween is simply All Hallows’ Eve, the night before. No document says “we did this to compete with the Celts,” and the May start date makes the theft story look exactly like what it is: a good yarn, told backwards.

What actually generated the customs everybody fights about — the costumes, the door-to-door — wasn’t Samhain at all. It came from the church’s own folk. On All Souls’ Day, November 2, the poor, and especially poor children, went souling: around to the wealthier houses, offering prayers for the family’s dead in exchange for soul cakes and bits of food. Charity, prayer, and food at the door. Alongside it ran guising in Scotland and Ireland — costumed rounds where you owed a song or a joke for your treat. Take a step back and look at that. Trick-or-treat’s ancestors aren’t a druid rite. They’re a Catholic almsgiving custom and a folk performance tradition. The thing being boycotted as pagan is, in large part, the descendant of a church charity practice.

And it kept evolving, the way folk customs do. Carried to America by immigrants, the door-to-door rounds ran into a rowdy prank culture — soaped windows, gates off hinges, outhouses tipped on Mischief Night. Towns, schools, and merchants responded the practical way: parties, parades, and treats, offered to buy the peace. The “trick” in trick-or-treat was originally a real if mostly harmless threat; the treat was the bribe that retired it. The phrase itself was showing up in print in Canada by the late 1920s. Sugar rationing during the Second World War shelved the candy for a while; then the postwar suburbs and the baby boom brought it back at full scale — UNICEF boxes from 1950, Disney’s “Trick or Treat” cartoon in 1952 — and it became the universal neighborhood ritual it is now. Commerce did the final mixing, too: Halloween runs roughly thirteen billion dollars a year in the United States by the National Retail Federation’s recent count. Whatever else it is now, it’s a thoroughly American, thoroughly commercial holiday. Folklorists like Hutton and Nicholas Rogers land where the evidence points: not pagan survival, not pure church invention, but a layered entanglement of seasonal customs, feasts for the dead, migration, and money. Compost, not a conveyor belt.

You can see the entanglement from my own front door, practically. November 1 and 2 — All Saints and All Souls themselves — are also Día de los Muertos here in the Southwest: ofrendas in the windows, families in the cemeteries, marigolds everywhere. Tucson’s All Souls Procession, held that weekend, draws well over a hundred thousand people downtown by recent counts. Whatever the season’s customs about the dead are, in this part of the country the most visible ones grew out of the Catholic calendar, not out of anybody’s grimoire.

So much for custody. Now the argument itself, because even a flawless pedigree wouldn’t settle it — and a flawed one, honestly examined, doesn’t either. The avoidance camp’s rule is: a thing with dark or pagan associations is off-limits to Christians, full stop. Apply that rule consistently and watch what it eats. Christmas trees. Easter eggs and Easter bunnies. Wedding rings. The names of the days of the week, which honor Norse and Roman gods every time a Christian checks a calendar. Nobody lives by this rule, including the people preaching it in October. They apply it to Halloween because Halloween is the one they can see. I made this argument about horror movies and I’ll make it here: you judge what people do by what it is and what they’re doing with it. A kid in a Spider-Man costume collecting fun-size Snickers is not participating in a rite. A harvest party is not a seance because they share a date.

Which brings me to the porch light, because I think the porch light is where this stops being abstract. Halloween is the one night of the year when the whole neighborhood comes to your door on its own — no invitation needed, no program, no strategy. And a porch light on that night is a signal every six-year-old can read. On: come on up, you’re welcome here, we don’t even need to know your name. Off: not interested. Don’t bother me.

A light is cheap now, but understand what it used to mean. A few centuries back, light at a door cost money — candles and lamp oil weren’t free — and darkness was every house’s natural state after sundown. In a village with no streetlights, a lit doorway was a prepared welcome, and an unlit one meant, honestly, no one will receive you here tonight. That’s the world the old customs grew in: the candle in the window, lit in Ireland for Mary and Joseph and for whatever traveler was out in the dark, a standing offer to strangers unknown. And it’s not a small theme in the faith itself. Hospitality to the stranger is commanded in it, over and over: Abraham running out to feed three strangers who turned out to be rather more than strangers; “I was a stranger and you welcomed me”; the letter to the Hebrews telling believers not to neglect hospitality to strangers, because by it some have entertained angels without knowing it. Souling night was that duty’s annual workout — doors ready, food ready, the poor expected at them and fed, prayers traded in return.

So here is my question for the dark houses, and I ask it as the neighbor down the street who can see which ones they are. The street came to your door this year, the way the poor once came to Christian doors on this same weekend, and the answer was a switched-off light. Why? Not “why don’t you celebrate Halloween” — that’s a matter of taste, and taste is free. Why is the welcome off? The faith that produced soul cakes and candles in windows — a faith whose own scriptures make a stranger at the door a test of the household — now has households that meet the one night of visiting strangers by pretending not to be home. The people who kept souling night would, I think, have a word for that, and it wouldn’t be “faithful.”

The workaround economy that has grown up around the boycott gives the game away, I think. The same churches that warn against Halloween hold Trunk-or-Treat and Harvest Festivals — the party kept, the street avoided, candy distributed in the church parking lot where the guest list is manageable. And at the far end stand the Hell Houses: walk-through haunted attractions run by churches as evangelism, with graphic rooms about hell, abortion, drunk drivers, despair — horror, built by hand, in the church’s own building, sold as ministry. I wrote recently that on a theater screen, horror is supposed to be demonic. Apparently in the fellowship hall it’s an outreach tool. The avoidance camp doesn’t actually avoid the thing. It just insists on owning the venue — and a light moved to a parking lot shines mostly on the people who are already yours.

One more layer, and it’s my favorite, because October 31 is not only Halloween. It’s also Reformation Day — this year is the 509th anniversary of the day Martin Luther set the Protestant Reformation off. The date half the church is hiding from is the date its own tradition was founded on. And even that founding story is told wrong, in the same way the Samhain story is told wrong. The famous image — Luther striding up and nailing his Ninety-five Theses to the Wittenberg church door — rests on an account written by Melanchthon in 1546. Melanchthon wasn’t in Wittenberg in 1517, Luther himself never mentioned nailing anything, and the historian Erwin Iserloh concluded in 1961 that the theses were mailed, not nailed: what Luther verifiably did on October 31, 1517 was write a letter to his archbishop, theses attached, respectfully demanding a debate. The hammer doesn’t even show up in artwork until 1697. Same story with “Here I stand, I can do no other” at Worms in 1521: it isn’t in the official transcript; it appears in the printed version. Movements don’t just remember their history. They typeset it.

That’s really the whole post in one sentence, and it cuts at every camp including, when I’m careless, my own. Check the earliest record, not the later printing. The Samhain of the pamphlets is a later printing. The stolen holiday is a later printing. The nailing is a later printing. The record underneath is stranger, duller in places, and better than all of them: a church feast that started in May, poor children praying for soul cakes, immigrants with their customs in their luggage, American kids and American candy, and a monk who, on the last day of October, wrote a letter and started an argument. Luther’s actual method, on the actual day, was engagement — put it in writing, demand the debate, take the consequences. A tradition born that way could stand to meet its own birthday standing up.

So should Christians celebrate Halloween? I’m an atheist; it’s not my holiday to assign. But by the standards Christians themselves profess — judge a thing by what it is, welcome the stranger, don’t hide your light — the answer looks obvious from my side of the street. The costumes are costumes. The candy is candy. The kids at the door are the neighborhood, arriving once a year, uninvited and welcome, the way the poor once arrived at doors that were expected to open. You can meet them in a costume of your own, with the bowl out and the light on. Or you can sit in the dark, in a house full of light, pretending nobody’s home. I’ve watched both kinds of houses. I know which street I’d rather live on.
