Halloween Is NOT Pagan: What the History Channel Gets Wrong About the Catholic Origins of Halloween
Separating historical facts from popular myths, questionable assumptions, and the enduring claim that the Catholic Church stole Halloween from the pagans.
By Chris M. Forte | My Catholic Defense
Every October, like clockwork, the same tired accusations make their annual appearance: Halloween is pagan, Christians should have nothing to do with it, and the Catholic Church supposedly hijacked an ancient Celtic festival and disguised it as a Christian holiday.
We hear these claims from certain Evangelical fundamentalists, self-described former occultists, modern pagans, and countless social media personalities who repeat whatever sensational Halloween story happens to be circulating.
Unfortunately, some popular historical documentaries and websites have helped perpetuate this narrative.
Among them is the History Channel.
In its article, How the Early Catholic Church Christianized Halloween, HISTORY declares that Halloween developed from the Celtic festival of Samhain and was subsequently appropriated by the Catholic Church.
That is quite a claim.
But is it historically accurate? Is there actual documentary evidence that a pope deliberately replaced Samhain with All Saints' Day? Did the Catholic Church simply rename a pagan holiday and hope nobody would notice?
Or have centuries of complex Christian, European, and American history been reduced to an oversimplified origin story?
As Catholics, we should have no difficulty acknowledging genuine pagan influences on European folklore. What we should reject is the assumption that every similarity between a pagan custom and a Christian celebration proves that Christianity stole something.
History requires evidence, not merely coincidence, conjecture, or endlessly repeated assumptions.
And when we investigate the actual origins of Halloween, a much more interesting—and significantly more Catholic—story emerges.
1. What exactly does the History Channel claim?
Let's begin by giving HISTORY a fair hearing.
In its October 27, 2025 update of How the Early Catholic Church Christianized Halloween, writer Patrick J. Kiger presents Samhain as Halloween's pagan ancestor.
The article describes ancient Celtic celebrations marking the end of the harvest season and the beginning of winter. It discusses beliefs about spirits, supernatural activity, bonfires, and offerings.
It then argues that the expanding Catholic Church gradually absorbed these customs, providing them with Christian meanings.
HISTORY also points to Pope St. Gregory the Great, who encouraged missionaries to adapt certain existing religious sites and customs for Christian purposes rather than necessarily destroy everything associated with the pre-Christian past.
The implication is straightforward: the Church took Samhain, Christianized it, and eventually produced Halloween.
Interestingly, HISTORY's own reporting elsewhere acknowledges more complicated origins. Its article about trick-or-treating describes contributions from medieval Catholic observances, British history, and European folk traditions, and admits that the custom's origins remain uncertain.
There is nothing inherently unreasonable about investigating possible cultural influences.
The problem begins when a plausible historical hypothesis is presented as though it were a firmly established fact.
The existence of Samhain does not, by itself, establish that Halloween was created from Samhain.
Nor does the Church's willingness to convert existing customs to Christian purposes prove that the feast of All Saints was created for that purpose.
Those are separate historical questions, and they deserve separate answers.
2. Samhain was real. But what do we actually know about it?
Let's establish something immediately: Samhain was a genuine seasonal observance in ancient and medieval Celtic culture.
Its name appears in early Irish literature, where it is associated with the transition into winter, seasonal gatherings, feasting, and important events.
Nobody needs to deny the existence of Samhain to defend the Christian history of Halloween.
However, our knowledge of its earliest religious ceremonies is incomplete.
The ancient Celtic peoples did not leave us a comprehensive, contemporary manual explaining precisely how Samhain was celebrated, what every ritual meant, or how those customs might have developed into later Halloween traditions.
Much of the surviving literary evidence comes from medieval Ireland, after Christianity had already become established.
This creates an important historical complication.
When we read medieval Irish accounts describing supernatural events associated with Samhain, how much reflects genuinely ancient pagan practices? How much reflects later folklore? How much represents the literary imagination of Christian-era storytellers?
Historians must carefully distinguish among these possibilities.
British historian Ronald Hutton, a leading scholar of British ritual history, has examined precisely these questions.
His research challenges the once-common assumption that Samhain can confidently be identified as both the ancient Celtic New Year and a universal pagan festival of the dead.
In his 2024 scholarly article, The Celtic New Year and Feast of the Dead, Hutton revisits the evidence behind these traditional interpretations.
His earlier book, The Stations of the Sun: A History of the Ritual Year in Britain, likewise emphasizes how difficult and ambiguous the historical evidence can be.
This does not mean Samhain had no supernatural associations.
It means that we must distinguish what the evidence demonstrates from what modern popular culture has taught us to assume.
And that distinction matters enormously when people confidently proclaim that Halloween is merely a pagan religious festival with a Christian label.
3. Christians were honoring their saints long before Halloween existed
Here is a fact that frequently disappears from popular Halloween discussions:
The Christian practice of commemorating martyrs and saints is considerably older than the medieval observance of Halloween.
From Christianity's earliest centuries, believers remembered those who had suffered and died for Christ.
These commemorations were not borrowed from Celtic paganism. They emerged within the life of the early Christian Church.
As the number of martyrs increased, Christians began celebrating collective commemorations rather than assigning every martyr a separate observance.
The historical record identifies early collective celebrations in the Christian East, including Antioch.
St. Ephrem the Syrian, who died in AD 373, is among the early witnesses associated with the commemoration of saints and martyrs.
St. John Chrysostom, who died in AD 407, also provides evidence of the ancient Christian tradition.
The Catholic Encyclopedia documents these early developments and shows that the observance did not suddenly appear in medieval Europe as a reaction to a Celtic festival.
In other words, the theological foundation of All Saints' Day was already firmly Christian.
The Church honored the saints because it believed that those who died in Christ remained members of His Body and shared in His victory over death.
The celebration arises naturally from Catholic beliefs about the Communion of Saints, the Resurrection, and eternal life.
None of those doctrines requires Samhain.
None originated with the Druids.
And none becomes pagan merely because a later liturgical feast happened to fall near a pre-Christian seasonal observance.
4. Pope Boniface IV and the Pantheon: A frequently overlooked historical fact
On May 13, AD 609 or 610, Pope Boniface IV dedicated the Pantheon in Rome as a Christian church in honor of the Blessed Virgin Mary and the martyrs.
The building became known as Santa Maria ad Martyres.
This dedication is historically important because it demonstrates the development of Christian collective commemorations independently of the November date now associated with All Saints' Day.
Consider what this means.
Here we have a major Christian commemoration honoring the martyrs in Rome during the spring.
Not October 31.
Not November 1.
And not in ancient Celtic territory.
Some writers have suggested that the May 13 date itself may have been associated with the ancient Roman festival of Lemuria. But the coincidence of dates does not establish that the Church intentionally adopted that festival either.
Indeed, that argument illustrates the very problem we are discussing.
If a Christian feast falls on a date formerly associated with a pagan celebration, are we automatically supposed to conclude that the Christian observance was stolen?
Of course not.
What historians need is evidence of the actual historical relationship.
The Pantheon's dedication is documented, and its Christian purpose was explicit: honoring Mary and the martyrs.
The theological reason for honoring the martyrs did not suddenly appear because pagans happened to celebrate something.
It was already part of Christianity.
5. Pope Gregory III and November 1: Where is the evidence of a Samhain conspiracy?
The next significant development concerns Pope Gregory III, who reigned from AD 731 to 741.
Gregory established an oratory within Old St. Peter's Basilica dedicated to the saints, martyrs, confessors, and faithful departed who had attained heavenly glory.
His pontificate is traditionally associated with the establishment of the November 1 observance in Rome.
The feast subsequently became more widely established in Western Christianity, particularly during the Carolingian period.
Pope Gregory IV, who reigned from AD 827 to 844, is traditionally credited with helping extend its observance more broadly, although historians debate some details of this process.
These developments are discussed in the historical literature surrounding the feast of All Saints.
Now comes the question that should concern anyone claiming the Church deliberately hijacked Samhain.
Where is the contemporary papal document stating that Gregory III chose November 1 to replace the Celtic festival?
Where is the decree declaring Samhain abolished and replaced by All Saints' Day?
Where is the correspondence explaining such a plan?
The standard historical accounts offered in support of this theory do not produce such a document.
Instead, they frequently point to the chronological proximity of the festivals and the Church's general history of Christianizing certain pre-Christian practices.
But that is not sufficient to demonstrate the specific intention attributed to Gregory III.
Furthermore, Rome was not a Celtic religious center.
The establishment of a Christian commemoration in Rome cannot simply be assumed to have been a targeted response to Irish or Scottish pagan observances.
There may have been cultural interaction and mutual influence as Christianity spread throughout Europe. That possibility deserves serious consideration.
But possibility is not proof.
And asserting a deliberate Church-wide strategy without direct historical evidence goes beyond what we can confidently establish.
6. What about Pope Gregory the Great and the conversion of pagan customs?
Supporters of the appropriation theory sometimes cite Pope St. Gregory the Great, who reigned from AD 590 to 604.
In AD 601, Gregory instructed Abbot Mellitus concerning the evangelization of the Anglo-Saxons.
He suggested that pagan temples could sometimes be cleansed and rededicated for Christian worship rather than destroyed, and that certain established communal celebrations could be redirected toward Christian purposes.
This is genuine historical evidence of an intentional missionary approach.
But what does it actually demonstrate?
It demonstrates that Pope Gregory recognized the practical and pastoral value of redirecting some existing customs toward Christianity.
It does not demonstrate that every Christian feast was created by appropriating a pagan festival.
Nor does it establish that All Saints' Day was deliberately placed on November 1 to replace Samhain.
Furthermore, the missionary instructions concerned Anglo-Saxon England. They were not a specific papal order about Samhain or the institution of Halloween.
This distinction is critically important.
A general policy cannot automatically be used as proof of a particular historical event.
Catholics also need not be embarrassed by the idea of genuine Christianization.
A building originally used for pagan worship can become a church.
A customary community gathering can be given a new Christian purpose.
Such transformations do not mean that Christian doctrine, worship, or religious identity become pagan.
They demonstrate that Christianity historically engaged with existing cultures rather than always demanding the destruction of every cultural practice.
Christianizing a custom is not the same thing as adopting pagan worship.
And it certainly does not establish that Halloween itself is a pagan religious observance.
7. A glaring historical error in HISTORY's own account
Perhaps the most troubling issue appears in HISTORY's article titled Samhain, updated August 26, 2026.
Under its discussion of Christian influence, the article attributes a fifth-century change in the feast's date to a Pope Boniface and describes a later Pope Gregory moving the celebration back to November.
There is a serious chronological problem here.
Pope Boniface IV did not live in the fifth century. He reigned from AD 608 to 615.
His dedication of the Pantheon took place in AD 609 or 610.
Furthermore, the November 1 observance was associated with developments during and after the eighth century, while All Souls' Day developed its own history and was promoted especially through the influence of St. Odilo of Cluny near the end of the tenth century.
The account compresses several centuries of different religious developments into a simplified narrative about popes moving a pagan festival around the calendar.
These are not insignificant details.
When an article claims to explain the origins of a religious observance, getting the chronology right is essential.
I am not suggesting that HISTORY's writers deliberately fabricated history. Popular historical articles frequently simplify complicated subjects, and errors can occur.
Nevertheless, Catholics have every right to ask why claims of pagan appropriation are repeated so confidently when some of the historical explanations supporting them contain factual mistakes.
If we are going to accuse the Catholic Church of stealing a pagan holiday, shouldn't we first establish exactly which pope supposedly did it, when he did it, and what historical evidence demonstrates his intention?
That seems like a reasonable expectation.
8. All Souls' Day: A Catholic tradition, not pagan ancestor worship
Another recurring accusation concerns All Souls' Day, observed on November 2.
Because the ancient Celts supposedly believed that the dead could return during Samhain, some writers suggest that Catholic prayers for the departed are simply Christianized pagan rituals.
But this argument overlooks something fundamental.
Praying for the dead is an ancient practice with biblical and Jewish roots.
In 2 Maccabees 12:43–46, Judas Maccabeus arranges an offering on behalf of fallen soldiers.
Catholics have traditionally understood this passage as biblical testimony supporting prayer for the dead.
The early Christian Church likewise remembered deceased believers in its liturgical prayers.
In Catholic theology, All Souls' Day does not involve summoning ghosts, communicating with spirits, or inviting the dead to return to their former homes.
It concerns praying for the faithful departed, especially those undergoing final purification.
The formal November 2 commemoration became particularly influential through St. Odilo of Cluny around AD 998, before spreading more widely.
This is a distinctively Christian theological tradition.
Of course, many cultures have commemorated their dead.
But the fact that pagans remembered deceased relatives does not make every Christian remembrance of the dead pagan.
Otherwise, we would have to conclude that funerals, cemeteries, memorial services, and even placing flowers on graves are inherently pagan simply because non-Christian cultures practiced similar customs.
That would be absurd.
The meaning of a religious act depends upon what is actually being done and believed, not merely upon superficial similarities.
9. Souling, guising, and the origins of trick-or-treating
HISTORY itself acknowledges the importance of medieval Christian traditions in the development of trick-or-treating.
One such tradition was known as souling.
In parts of England, people visited households requesting food, particularly soul cakes, in exchange for prayers for the deceased.
Other customs developed in Scotland and Ireland, including guising, in which people dressed in costumes and performed songs, jokes, or verses in exchange for gifts.
These traditions contributed to the eventual development of American trick-or-treating.
Were there also older European customs involving disguises, seasonal festivities, or offerings?
Certainly, there may have been.
But again, cultural similarities do not automatically establish a direct line of descent from ancient pagan religious ceremonies.
Indeed, HISTORY's own article How Trick-or-Treating Became a Halloween Tradition acknowledges that the precise origins are complicated and uncertain.
Modern American trick-or-treating also owes much to nineteenth- and twentieth-century immigration, community celebrations, and changing attitudes toward children's entertainment.
An American child wearing a superhero costume and collecting chocolate bars is participating in a modern social custom.
That child is not thereby worshiping an ancient Celtic deity.
And Catholics need not manufacture theological concerns where no actual pagan worship exists.
10. Jack-o'-lanterns, costumes, and other Halloween traditions
The familiar jack-o'-lantern has its own complicated history.
Traditions involving carved turnips and other vegetables were present in Ireland and Britain, and the legend of Stingy Jack became associated with wandering lights and the supernatural.
When Irish immigrants brought their customs to North America, pumpkins provided an abundant and convenient alternative.
Likewise, Halloween costumes have many possible influences, including masquerading, folk celebrations, supernatural storytelling, theatrical traditions, and more modern popular entertainment.
None of this requires us to deny the possibility of pre-Christian influences.
But neither should we leap from the existence of an older folk custom to the claim that every modern participant is practicing pagan religion.
A carved pumpkin has no inherent religious power.
A costume is not automatically an act of spiritual devotion.
A neighborhood Halloween party is not a pagan ceremony simply because some of its decorations draw upon European folklore.
Catholics should exercise prudence when choosing what to celebrate or portray. Activities deliberately involving occult practices, attempts to communicate with spirits, or glorification of evil raise legitimate religious concerns.
But innocent recreation is another matter entirely.
The Church distinguishes between genuine superstition and ordinary cultural practices.
Halloween decorations and costumes do not automatically become occult practices because someone discovers a possible pre-Christian parallel.
11. The actual meaning of Halloween: All Hallows' Eve
Perhaps the most revealing part of this controversy is something remarkably simple.
The word Halloween comes from All Hallows' Eve.
Hallow is an old English word for a holy person or saint.
All Hallows' Day is All Saints' Day.
And All Hallows' Eve is its eve or vigil.
The name itself comes from the Christian calendar.
That does not prove that every custom practiced on October 31 originated in Christianity. Nor does it erase the possibility of genuine pre-Christian contributions to Halloween folklore.
But it does establish that the holiday's familiar English name is Christian.
And its place within the traditional Catholic calendar is unmistakable.
All Hallows' Eve introduces the observances collectively known as Allhallowtide:
October 31 — All Hallows' Eve: The eve of All Saints' Day.
November 1 — All Saints' Day: The solemn celebration of all the saints in heavenly glory.
November 2 — All Souls' Day: The commemoration of all the faithful departed.
Together, these observances direct our attention toward death, judgment, the Resurrection, eternal life, and the Communion of Saints.
They remind us that death does not have the final word.
Christ does.
That is the religious framework within which Catholics can understand Halloween.
12. What serious historians actually debate
It would be equally irresponsible for Catholic apologists to insist that there is absolutely no connection between Samhain and Halloween.
That would go beyond the evidence in the opposite direction.
Historical development is rarely that simple.
Many customs evolved over centuries through interaction among different peoples, religions, and cultures.
Some European Halloween traditions may preserve elements of older seasonal celebrations.
Others demonstrably emerged within medieval Christianity.
Still others developed much later, particularly in the United States.
The important distinction is between acknowledging possible cultural influences and asserting that the entire holiday was deliberately stolen from paganism.
Ronald Hutton's historical scholarship provides an excellent reason to resist overly confident origin stories.
Likewise, scholarship on All Saints' Day points to developments within the early Christian Church, Rome, the Frankish world, and the British Isles. The process was considerably more complicated than one pope simply renaming Samhain.
A historical discussion published by the University of California Press also challenges the assumption that the ninth-century expansion of November 1 observances was necessarily motivated by a desire to suppress Samhain.
This is why careful scholarship matters.
There is a difference between saying:
Some Halloween customs may reflect pre-Christian European traditions.
And saying:
Halloween is a pagan holiday that the Catholic Church deliberately stole and disguised as Christianity.
The first is a reasonable historical proposition.
The second requires stronger evidence than its advocates typically provide.
13. Why do so many Christians believe Halloween is Satanic?
We also need to address the modern religious controversy.
Some fundamentalist Protestant ministries present Halloween as inherently demonic. Certain sensational testimonies by self-described former occultists have reinforced the belief that October 31 belongs exclusively to Satan.
Meanwhile, some modern pagans and Wiccans celebrate Samhain as an important religious occasion.
But the fact that a contemporary religious group celebrates October 31 does not mean that everyone else celebrating on that date participates in its religion.
Modern religious identity cannot simply be projected backward onto every historical custom associated with the season.
Nor should Christians automatically accept extraordinary supernatural claims without examining the evidence.
Catholics have no obligation to embrace occult practices. In fact, the Catechism expressly rejects divination, magic, and attempts to manipulate occult powers (CCC 2115–2117).
But that condemnation does not extend indiscriminately to every costume party, carved pumpkin, bowl of candy, or family celebration.
We should not confuse cultural entertainment with religious worship.
And we certainly should not allow sensationalism to replace historical investigation.
14. So, is the History Channel entirely wrong?
No.
And intellectual honesty requires us to acknowledge that.
HISTORY correctly identifies Samhain as an important Celtic seasonal observance. It recognizes that older European folklore contributed to Halloween traditions. It also acknowledges the medieval Catholic contribution to customs such as souling.
The problem is not everything HISTORY says.
The problem is the excessive certainty with which some of its articles present the relationship between Samhain and the Christian feast of All Saints.
Its treatment of the subject also contains historical errors and simplifications that deserve correction.
A more accurate explanation would be that Halloween developed through a long and complicated interaction of Christian liturgical observances, European seasonal folklore, regional folk customs, immigration, and modern American culture.
Some elements may have pre-Christian antecedents.
Others have clearly identifiable Catholic roots.
And the origins of still others remain uncertain.
That is considerably more historically defensible than declaring Halloween pagan and treating the matter as settled.
15. Conclusion: Halloween belongs to no pagan monopoly
As Catholics, we do not need to rewrite history to defend our faith.
We do not need to deny that pagans existed, that Samhain was celebrated, or that European folk customs influenced later Halloween festivities.
But neither should we accept the accusation that our ancestors simply stole a pagan holiday and disguised it with Christian language.
The veneration of martyrs and saints is an ancient Christian practice.
The prayers of the Church for the faithful departed arise from biblical and early Christian traditions.
The development of All Saints' Day has its own documented history, stretching across centuries and involving multiple regions of Christendom.
And Halloween, by its very name, remains historically connected with the Christian observance of All Hallows' Eve.
This does not mean every modern Halloween activity is Christian, appropriate, or spiritually beneficial. Catholics should always exercise sound judgment.
But it does mean that blanket condemnations of Halloween as inherently pagan are historically and theologically unjustified.
The History Channel is right to explore ancient Celtic culture and the complicated development of Halloween traditions.
But it should be just as careful about distinguishing historical evidence from speculation when discussing the Catholic Church.
Too often, popular Halloween histories begin with the assumption of pagan appropriation and then interpret every coincidence as confirmation.
That is not how responsible historical investigation should work.
The burden of proof rests upon those claiming deliberate religious theft.
And a shared calendar date is not sufficient evidence.
So this October 31, when somebody insists that Halloween is nothing more than a pagan festival stolen by the Catholic Church, ask them a simple question:
Where is the historical evidence?
Not a modern documentary repeating the claim.
Not a social media meme.
Not a speculative connection based upon similar dates.
Actual historical evidence.
Until that evidence is produced, Catholics have every reason to celebrate the authentic Christian traditions of Allhallowtide with confidence.
Halloween does not have to be a celebration of darkness. For Catholics, All Hallows' Eve can be a reminder that the saints have conquered through Christ, that death has been defeated, and that the light of Christ shines even in the darkest night.
And that is a history worth remembering.

Editorial note: This is an original Catholic apologetics commentary, not a claim that historians unanimously reject links between Samhain and Halloween. The criticism concerns the certainty of specific appropriation claims, identifiable chronological errors, and the need to distinguish historical evidence from inference.
