Where Halloween—and “Trick-or-Treat”—Really Came From?

Historical development, what the Catholic Church teaches and how the feast developed, a comparison table, a timeline, quote boxes, and a list of the most important sources (primary/secondary) so readers can check the originals.


Short answer (TL;DR)

Halloween as we know it is a layered cultural product:

  • It preserves ancient Celtic elements (Samhain, a harvest/“thin-veil” festival observed ~Oct 31–Nov 1). Encyclopedia Britannica+1

  • In the early Middle Ages the Christian liturgical calendar placed All Hallows’ (All Saints’) Day on November 1 and All Souls’ Day on November 2; the evening before (the vigil) became known as All Hallows’ Eve (Halloween). The Church formally adopted the November 1 date in the 8th–9th centuries. Encyclopedia Britannica+1

  • Trick-or-treating evolved from medieval “souling” and other local customs (begging for soul-cakes, “guising”) and was transformed in North America into modern door-to-door candy begging by the early 20th century. Wikipedia+1

  • The Catholic Church recognizes the liturgical roots (All Hallows’ Eve = vigil of All Saints) and encourages prayer, remembrance of the dead, and pastoral guidance on popular customs; many Catholic writers describe pagan practices being “baptized” into Christian observance. Vatican News+1


1. Origins and earliest roots

Samhain (Celtic):
Samhain (pronounced roughly SAH-win), a Gaelic/Insular Celtic festival historically observed on the evening of October 31 into November 1, marked the end of the harvest and the “beginning of winter” when boundaries between the worlds were thought to be thin. Customs included bonfires, divination and wearing disguises—practices later associated with Halloween. Encyclopedia Britannica+1

Early Christian feasts:
By the 7th–9th centuries the Western Church established feasts to honor martyrs and all saints. Pope Boniface IV (early 7th c.) had a feast for martyrs; Pope Gregory III (8th c.) dedicated a chapel on November 1 and that date spread; later medieval practice added All Souls’ Day (Nov 2) to pray for the faithful departed. The three-day cycle (Oct 31–Nov 2) is called Allhallowtide. Encyclopedia Britannica+1

Quote (Vatican News): “The name itself comes from All Hallow’s Eve – that is, the Vigil of All Saints’ Day… Immediately afterwards, on November 2, the Church commemorates all the faithful departed…” Vatican News


2. How “trick-or-treat” and popular customs developed

Medieval souling & soul-cakes:
From at least the medieval period in Britain there was a practice called souling: poor people or children went house to house (around Allhallowtide), offering prayers for the dead in exchange for “soul-cakes” or food. That custom carried the theme of visiting house to house and receiving food / alms. Wikipedia+1

Guising and mask/dress traditions:
The practice of dressing in disguise (to confuse or placate spirits) existed in Celtic and later rural British traditions; in the 19th–early 20th centuries this appeared as “guising” in Britain and among immigrants. Encyclopedia Britannica+1

North American reinvention — modern trick-or-treat:
Mass immigration (esp. Irish) and 20th-century American communities, combined with school and civic events, turned various Old World customs into the popular candy-centric “trick-or-treat” by the 1920s–1950s; by mid-20th century the practice had become widespread in the U.S. and Canada. HISTORY+1


3. The Catholic Church: recognition, teaching, and pastoral stance

Liturgical origin and Church teaching:

  • The vigil name—All Hallows’ Eve—derives directly from the liturgical vigil of All Saints’ Day (Nov 1). The Church long honored the memory of the dead and offered prayers for them; the Catechism explicitly records this ancient practice and bases the doctrine of prayers for the dead (and Purgatory) on Scripture plus Tradition. Vatican News+1

Catechism references (key paragraphs):

  • CCC 958 — Communion of saints: the Church has, from earliest days, honored the memory of the dead and prayed for them. Vatican

  • CCC 1032 — Purgatory and prayers for the dead are rooted in both Scripture (e.g., 2 Maccabees) and early Christian practice; the Church commends almsgiving and prayers for the dead. Vatican

Pastoral approach to popular customs:
The Church distinguishes between the liturgical/religious origin (Allhallowtide) and later folk or pagan elements. Many Catholic commentators and official speakers encourage Christians to reclaim the vigil by focusing on prayer, the communion of saints, and remembrance while using prudence about secularized or occultized practices. Vatican and other Catholic sources often describe the Church absorbing and transforming local customs (sometimes called the “baptizing” of customs). Vatican News+1


4. Biblical, Patristic and historical evidence for commemorating the dead

Biblical evidence:

  • The practice of making atonement or offerings for the dead appears in 2 Maccabees 12:43–45 (an example used by the Church to justify prayer for the dead). The Catechism refers to this passage when treating Purgatory and suffrages. Vatican

Early Church Fathers & practice:

  • Patristic writers (e.g., Tertullian) and later records mention anniversary masses and offerings for the deceased—evidence that praying and offering suffrages for the dead were practiced in the early centuries. The long tradition of commemorations and martyrs’ feasts fed into the later institutionalized All Saints/All Souls observances. Christian Classics Ethereal Library+1

6. Concise historical timeline (key moments)

  • Iron Age / pre-Christian Celtic period (before 1st c. AD onward): Samhain observed around Nov 1. Encyclopedia Britannica

  • ~6th–7th century: Christian commemorations of martyrs and local “feasts of all martyrs” exist (e.g., May 13 in Rome). Encyclopedia Britannica

  • 8th century (c. 731–741): Pope Gregory III dedicates chapel and Nov 1 becomes tied to All Saints in Rome. Encyclopedia Britannica

  • Medieval period: Souling and other customs (soul cakes, visiting, bonfires) appear and persist in Britain and elsewhere. Patristic/medieval sources record prayers for the dead. Wikipedia+1

  • 19th century: Irish and British customs carried in immigration waves to North America. The Library of Congress

  • Early 20th century (1910s–1930s): “Guising” appears in North American accounts; trick-or-treat becomes popularized by mid-20th century. Wikipedia+1

  5. Folklore resources on souling and soul-cakes (English Heritage; folk song indexes). English Heritage+1


8. What the Bible or Fathers do (and don’t) say about Halloween

  • The Bible does not mention “Halloween” (it’s a late cultural-linguistic term). The scriptural texts used historically to support prayer for the dead include 2 Maccabees 12:43–45 (as cited in the Catechism) — a practice taken up by the Church as part of its tradition. Vatican

  • Patristic evidence: early Christian writers (e.g., Tertullian and later authors) attest to commemorations and offerings/masses for the dead—this supports the historical roots of Allhallowtide as a time for remembering the dead. Christian Classics Ethereal Library+1


9. Pastoral takeaway — is Halloween “Catholic” or “pagan”? What should Catholics do?

  • Historically: Halloween is a mixture. The name and one layer are Christian (All Hallows’ Eve = liturgical vigil). Some elements trace to pre-Christian festivals (Samhain). Over centuries the Church both created new commemorations (All Saints / All Souls) and adapted/converted local practices. Wikipedia+1

  • Pastorally: Many bishops and Catholic writers encourage using Allhallowtide as an opportunity to teach about the communion of saints, to celebrate All Saints on Nov 1, and to pray for the faithful departed on Nov 2. For secularized or commercialized Halloween practices, Catholics are encouraged to exercise prudence (avoid occult elements) and to reclaim the vigil by prayer, works of charity, and responsible family activities. Vatican News+1

“In full consciousness of this communion of the whole Mystical Body of Jesus Christ, the Church … has honored with great respect the memory of the dead; and ‘because it is a holy and wholesome thought to pray for the dead that they may be loosed from their sins’ she offers her suffrages for them.” — Catechism of the Catholic Church (para. 958). Vatican

“Halloween’s origins date back more than 2,000 years to the Celtic festival of Samhain… People believed that on this night the spirits of the dead roamed the earth.” — Britannica / History summaries. Encyclopedia Britannica+1
