Hallowtide: How the Church Shaped Halloween

All Saints' Day, All Souls' Day, soul cakes, and the medieval transformation of pagan customs into the Halloween we recognize.

The standard narrative goes like this: the Catholic Church saw a popular pagan festival, couldn’t stamp it out, and slapped a Christian label on it. Like most standard narratives, this one contains some truth, considerable oversimplification, and a few things that are probably wrong.

The Feast Day Question

Pope Boniface IV consecrated the Pantheon in Rome as a church dedicated to the Virgin Mary and all martyrs on May 13, 609 CE. This is the earliest clear precursor to All Saints’ Day, and it was in May, not November. Pope Gregory III (731-741) later dedicated a chapel in St. Peter’s Basilica to all saints on November 1, but it’s unclear whether this applied beyond Rome.

The decisive move came from Pope Gregory IV, who in 835 extended the November 1 feast to the entire Frankish Empire at the request of Louis the Pious. Whether Gregory chose November 1 specifically to co-opt Samhain or because the post-harvest timing made practical sense for feeding the pilgrims who traveled to Rome is something historians genuinely argue about. The “deliberate co-optation” theory is popular but not proven.

What we know: by the ninth century, November 1 was All Saints’ Day (All Hallows’ Day) across Western Christendom, and October 31 was its vigil, All Hallows’ Eve. Halloween.

All Souls’ Day and the Cult of the Dead

In 998, Odilo of Cluny designated November 2 as All Souls’ Day, a day for praying for the dead in Purgatory. This completed what became known as Hallowtide or Allhallowtide, a three-day observance spanning October 31 through November 2. The timing created a concentrated period focused on death, remembrance, and the afterlife that aligned neatly with (and probably reinforced) older folk beliefs about this being a season when the dead were close.

The theology of Purgatory gave medieval Christians a specific reason to engage with their dead. Unlike the saints in heaven, souls in Purgatory needed help. Prayers, masses, and good works by the living could shorten their suffering. This wasn’t abstract doctrine. It was personal. Your grandmother might be in Purgatory right now, and what you did on All Souls’ Day could make a material difference.

This belief powered an entire economy of remembrance: endowed masses, chantry chapels, and the practice that matters most to our story, soul cakes.

Soul Cakes and Souling

Soul cakes were small round cakes, sometimes marked with a cross, baked for All Souls’ Day. The practice of “souling,” going door to door asking for soul cakes in exchange for prayers for the household’s dead, is documented in England from at least the fifteenth century, though it likely started earlier. John Mirk’s Festial (c. 1400) describes the custom, and it persisted in parts of England into the twentieth century.

The exchange was straightforward. A poor person (often a child) would visit homes, receive a cake, and promise to pray for the souls of the household’s deceased. Each cake represented a soul released from Purgatory. Shakespeare references the practice in The Two Gentlemen of Verona (“Speed: … she is as slow in words as a snail in going — yet she is too fast for Elias. She is of good discourse, and well read in the nature of things. Valentine: How know’st thou that she is not slow? Speed: Marry, by these special marks: first, you have learned, like Sir Proteus, to wreathe your arms, like a malcontent; to relish a love-song, like a robin-redbreast; to walk alone, like one that had the pestilence; to sigh, like a school-boy that had lost his A B C; to weep, like a young wench that had buried her grandam; to fast, like one that takes diet; to watch like one that fears robbing; to speak puling, like a beggar at Hallowmas.”) The “beggar at Hallowmas” is a souler.

If you’re thinking this sounds like an early version of trick-or-treating, you’re not wrong. The structural similarity (going house to house, receiving food, implicit social obligation) is hard to miss.

Guising and Mumming

Medieval and early modern records from Scotland and Ireland describe “guising” on Halloween night. Participants wore disguises (often simple affairs of blackened faces or clothes worn inside out), went door to door, performed songs or recitations, and received food or coins. The earliest clear reference to guising at Halloween in Scotland dates to 1585, though the practice was likely older.

Mumming, the broader tradition of costumed performance associated with various calendar customs, overlapped with Halloween guising in the British Isles. These weren’t costumes in the modern sense of dressing as a specific character. They were disguises, intended to render the wearer unrecognizable. Whether this originated from a belief that disguise protected against spirits, or simply from the general atmosphere of misrule associated with the season, is another question without a definitive answer.

Bonfires, Nuts, and Apples

Bonfires remained central to Halloween observance in Scotland and Ireland throughout the medieval period and well beyond. The tradition of burning bonfires on hilltops persisted in parts of Scotland into the nineteenth century, directly echoing (and possibly descending from) the Samhain fires.

Divination games were enormously popular at medieval and early modern Halloween gatherings, particularly those related to marriage. Nut roasting (two nuts placed in a fire, their behavior predicting whether a couple would stay together), apple peeling (the peel thrown over the shoulder to form a future spouse’s initial), and mirror gazing (staring into a mirror to see one’s future partner) were widespread. Robert Burns’ 1786 poem “Halloween” documents many of these practices in detail, capturing a tradition that was already ancient when he described it.

The Medieval Legacy

The medieval Church didn’t destroy the older customs. It gave them a new framework. Spirits of the dead became souls in Purgatory. Offerings became soul cakes. The thin boundary between worlds became the eve of the holiest day for remembering the dead. The folk practices survived because the new theology accommodated them, and the new theology stuck because the folk practices gave it emotional weight.

By the time the Reformation challenged Purgatory and the cult of the saints, these customs had been woven into community life for centuries. In Protestant England, Hallowtide observances faded (replaced partly by Guy Fawkes Night on November 5). In Catholic Ireland and Scotland, they endured, waiting to cross the Atlantic.
