Every October someone tells you that Halloween is the ancient Celtic festival of Samhain, when the druids lit fires to keep away the returning dead, and that the church painted a saints' day over it. Neopagans tell it with pride and anti-Halloween Christians tell it as a warning. They are telling the same story, and the story is younger than the light bulb. This page goes custom by custom and asks one question of each: when is it first written down, and what stands between that record and a pagan Ireland that was Christian by about 600? The household's working read was that the holiday is too modern for much to have survived. That read is mostly right, with one correction and one real exception. The correction: the date and the name are old, but they are Christian. A feast of all saints on 1 November first shows up around 800, in Irish and Northumbrian churchmen's calendars and letters, and Francia made it law in 835. Nobody wrote down why that day was chosen. The exception: in the Gaelic world the night of 31 October was already uncanny in the earliest Irish stories, and that may be older than the church. What the record does not show is anyone in medieval Ireland doing anything on Halloween. The first Halloween with documented practices is medieval England's, and it was Catholic: bells rung all night for the souls in purgatory. Nearly everything people actually do on Halloween, though, from costumes and trick-or-treating to pumpkins and apple games, is first recorded between 1400 and 1950. The "pagan roots" story itself is a Victorian theory, first put forward in 1886 and 1890.
The household keeps Halloween. The Pragmatist's Guide holds it up as a model of a holiday that works, and says why: it is built for children, it runs on roleplay, and it has an exchange at its centre, "candy in exchange for showing up in a costume" (TPG 20.0). The same chapter proposes building a new ritual into it, a day for "walking in someone else's shoes" that asks what it must be like to be a vampire. The culture chapter gives the rule behind that: "traditions often live or die based on how much kids like them—this is why Halloween thrives while Lent languishes" (TPG 30.6). So the house treats Halloween as cultural technology. The objection it hears is that the technology is a pagan rite in disguise. This page checks that objection.
It is the same question the house has already answered for Christmas. The episode "Christmas Was Not a Pagan Holiday" (TPS 76.0) found Christian evidence for 25 December older than any evidence for a pagan feast on that date, and traced many of the pagan-origin claims to nineteenth-century scholarship. Halloween is the harder case, because here there really was a pre-Christian festival near the date. So the method has to be stricter than "it looks similar."
A root needs a record at both ends and nothing unexplained in between. To say a Halloween custom descends from paganism, you need the custom attested among pagans, the same custom attested later among Christians, and a reason to think it ran unbroken through the centuries between. Two of those three is a guess. A bonfire in 1780 and a bonfire in 300 BC do not make a lineage. People light fires in November because it is dark and cold.
Pagan Ireland did not write. Saint Patrick's mission is traditionally dated to 432, and Ireland was broadly Christian by the end of the 500s. Everything we know about Samhain from Irish sources was written down by Christian monks, the earliest of it in the 700s to 900s and most of it later. That cuts both ways and the page says so: silence before 600 proves nothing, but every "ancient" detail reaches us through a Christian pen, centuries after the last pagan generation.
Date each custom by its first record. Not by the age of the oldest thing it resembles. Where a later record is the first only because nobody was collecting folklore before, the page says so (counterweight 6).
The corpus's rule on dated things. A practice with a date and an author is a human practice (TP 35.0.1). That cuts against All Saints' Day as a command, since it has two dates and two popes. It does not make the holiday pagan. The house's question about a custom is what it does, not what it resembles (TP 8.0).
One row per piece of the holiday. The dot is the first record; the line runs from there to today, so its length is how old that piece actually is. The shaded band is pagan Ireland. Read down the chart and almost nothing reaches back into the band.
Plotted years: Coligny c. 150 (Gaul, not Ireland, and which part of the year the feast fell in is disputed); Gregory III's oratory 731–741 (its 1 November date is later tradition); the Félire Óengusso c. 800 (1 November and 20 April); Louis the Pious 835; the earliest Samhain tales c. 900 (the Ulster tales are often dated earlier, the manuscripts later); All Souls c. 1030 (998 by tradition); souling 15th century; guising 16th century; Highland pranks 1736; Mayne 1780 and Burns 1785; turnip lanterns 19th century; "jack-o'-lantern" for a carved pumpkin 1837; Halloween pumpkin 1866; Rhys 1886; Frazer 1890; Sault Daily Star 1917; nationwide spread 1930s–early 1950s; Wicca 1950s.
Short answer: nobody recorded the reason. Every explanation on offer is a modern inference from the order in which the evidence appears, so here is that order.
| When | Evidence |
|---|---|
| 4th century, East | Feasts of all the martyrs, set by Easter rather than by a fixed date: Antioch on the Sunday after Pentecost (Chrysostom's 74th homily), the East Syrians on the Friday after Easter (by 411). The Greek church still keeps All Saints on the Sunday after Pentecost. |
| 609/610, Rome | Boniface IV rededicates the Pantheon to Mary and all the martyrs on 13 May, and Rome keeps that date. |
| 731–741, Rome | Gregory III builds an oratory in St Peter's for relics "of the holy apostles and of all saints, martyrs and confessors." The standard histories say he dedicated it on 1 November, but that tie is weak. A large synod did meet at St Peter's on 1 November 731, while one reconstruction dates the oratory's dedication to 12 April 732. The firm November date for Rome comes later. |
| c. 800, Ireland | The Félire Óengusso (dated c. 800 or 828–833; the manuscripts are late medieval) puts "the great crowd of saints" on samain, 1 November. But it, like the Martyrology of Tallaght, keeps a feast of "all the saints of Europe" on 20 April, and Elva Johnston (UCD) reads 20 April as the weightier of the two. Tallaght's surviving copy is missing the page covering 1 November. |
| c. 798–800, Northumbria → Bavaria | Alcuin, trained at York, writes to Arno of Salzburg urging him to keep the feast on 1 November. Salzburg adopts it. So the English church already kept the date. |
| 835, Francia | Louis the Pious, at Pope Gregory IV's urging, orders 1 November kept across Gaul and Germany (recorded by Sigebert of Gembloux in the 12th century). This is the decree that made the date universal in the West. |
| c. 1170, Ireland | The Martyrology of Gorman has dropped the April feast. 1 November is now sruithló na samna, "the venerable day of Samain," and 31 October is marked as its eve. |
The four explanations, ranked. (1) An insular date that spread to the continent. The earliest datable 1 November evidence is in Ireland and Northumbria about 800, and it reached the Franks through Alcuin's network. This fits the evidence best. J. Hennig traced the line Ireland → Northumbria → continent; Hutton argues the English, Germanic side carried it. (2) The anniversary of Gregory III's oratory. This is the traditional account, but it depends on a dedication date that the sources do not secure. (3) Harvest food for pilgrims. The story that Rome moved the feast from May so the crowds could be fed after harvest is first told by medieval liturgists centuries after the fact. There is no contemporary evidence for it. (4) Chosen to replace Samhain. If anything favours this, it is the Irish entry in (1). But the Irish themselves kept their main all-saints feast in April at first, which is odd if the date was picked to defeat their own festival. And the church's records, from Gregory the Great's advice to the English mission in 601 onward, say openly when a feast is meant to replace a pagan one; none says so for 1 November.
What this does to the page's thesis. It narrows it. The Irish may have helped choose the date, and by 1170 the Irish church had openly fused the two names. That is a real Samhain contribution to Halloween: a calendar slot, filled with Christian content. It is still not a ritual.
Were the earliest Halloweens actually kept in Ireland or the Gaelic regions, or was the Irish link added later? Sort the evidence by place and the answer is mostly the second.
| Where | Medieval record (before 1500) | First folk "Halloween" customs |
|---|---|---|
| Ireland (Gaelic) | Samain as an assembly, a market, a court day and a tribute day. In the stories, a night when the síd stand open. No record of anyone doing anything on its eve: no divination, no disguise, no lanterns, and no fire rite (the texts put the druids' fires at Beltaine, 1 May). The church fuses the name with All Saints by c. 1170. | Late 18th century onward: food collected "in the name of St Colm Cille" (reported by Charles Vallancey, 1780s); Maclise's painting Snap-Apple Night of a Cork party (1833); turnip lanterns (19th century); the Irish Folklore Commission's schools survey (1937–39). |
| England (not Celtic) | The best-documented medieval Halloween anywhere. Church bells rung through the night of 31 October for the souls in purgatory, paid for in parish accounts. Hallowmas watches, soul cakes, prayers for the dead. Entirely Catholic, and ended by the Reformation, which is why nobody remembers it. | Souling into the 19th century, and in parts of the north into the 1930s. Bonfires shift to 5 November after 1605. |
| Lowland Scotland (Scots-speaking) | Nothing specific. | The first dense descriptions of folk Halloween. John Mayne's "Hallowe'en" (1780) and Burns's "Halloween" (1785, Ayrshire): kale stalks, nuts in the fire, apples and mirrors. The word "Hallowe'en" itself is Scots. Guising is recorded from the 16th century. |
| Highlands, Man, Wales | Wales has its own winter calends, Calan Gaeaf. Wales is Brythonic, not Gaelic, so it had no Samhain. Its customs, shared with the others, point to the start of winter itself rather than to an Irish festival. | Highland pranks (1736); bonfires in the Highlands, Man and Wales (early modern); Manx Hop-tu-Naa and Welsh Nos Calan Gaeaf (19th-century records). |
| North America | — | Arrives with Irish and Scots immigrants in the 19th century. This is where the Irish link is real: American Halloween is the 19th-century Irish and Scottish folk holiday, reworked from the 1880s to the 1950s. |
Reading it. The Irish link in the popular story joins two separate things. One is real: 19th-century Irish and Scottish immigrants brought 19th-century folk Halloween to America. The other is supposed: those 19th-century customs descend from pre-600 Samain. For a thousand years in between, Ireland's record shows a name, a date and a mood, but no practice. The earliest Halloween anyone can document being kept is English and Catholic. The earliest detailed folk Halloween is Lowland Scots. Neither is Gaelic.
How plausible is the Samhain link, then? It depends on the claim. "The name survives": certain, since the Irish word for November is still Samhain and Halloween is Oíche Shamhna. But names outlive meanings; Wednesday is still Woden's day. "The sense that the night is uncanny is pre-Christian": plausible, perhaps better than even. It is in the earliest stories, and it lasts into 19th-century fairy lore, though it is thinly recorded between about 1200 and 1700. "The Irish helped put All Saints on 1 November": possible, and the strongest new point for the Celtic side. "Any Halloween practice comes from Samhain": weak. Of all the customs, only the bonfires have any case, and the Irish texts put their sacred fires in May. "Halloween is Samhain in disguise": no.
Four grades. Pagan, real means a pre-Christian practice is attested and plausibly connected. Plausible, unproven means the custom could be old but the record starts late. Christian means the earliest record is Christian and nothing earlier is needed to explain it. Modern means the record starts after 1700 and the custom is documented as new.
| Piece of Halloween | First record | What the record shows | Grade |
|---|---|---|---|
| The date, 31 Oct / 1 Nov | c. 800 Ireland and Northumbria; 835 Francia | The feast is Christian. Why it fell on 1 November is unknown; see Exhibit A2. Rome kept an all-martyrs feast on 13 May from 609/610. Gregory III (731–741) built an all-saints oratory in St Peter's, but the tie of that oratory to 1 November rests on later tradition, and one reconstruction dates its dedication to April 732. The earliest datable 1 November evidence is from the islands around 800: the Irish Félire Óengusso sets "the great crowd of saints" on samain, 1 November, and the York-trained Alcuin urged Arno of Salzburg to keep the feast that day. In 835 Louis the Pious, at Pope Gregory IV's urging, made it law across the Frankish empire. The eve is simply the vigil, as with Christmas Eve. | Christian why that day: unknown; an Irish role is possible |
| The name | Old English; "Hallowe'en" in print by 1780 | All Hallows' Even: the evening before the feast of the hallows, the saints. "Hallowe'en" is the Lowland Scots contraction (even → e'en). John Mayne's poem "Hallowe'en" (1780) and Robert Burns's "Halloween" (written 1785) are the early literary uses. The name is a church calendar entry and nothing else. | Christian |
| A night of the dead | c. 1030 (998 by tradition) | Remembering the dead attaches to these days through All Souls' Day, which Abbot Odilo of Cluny set on 2 November for his monasteries. The Catholic Encyclopedia notes the decree was probably after 1030, not 998. It spread through the Western church over the next two centuries. For Samhain itself, Hutton finds "no evidence that it was connected with the dead." The festival-of-the-dead reading was Frazer's, and it rested on analogy, not on any record of such a festival. | Christian |
| An uncanny night: the síd open, the otherworld abroad | Irish tales, written c. 800–1100 | This is the real thread. In Echtra Nerai a dare on Samhain night leads Nera into the síd and to a vision of the hall burnt the next Samhain. The Boyhood Deeds of Fionn says the síd "were always open at Samhain." Tochmarc Emire lists Samhain first of four seasonal feasts. Hutton accepts that Samhain was "a time when supernatural forces were especially to be guarded against or propitiated." Every one of these texts was written by Christian monks, centuries after conversion, and they are stories, not ritual instructions. What they show is that the start of winter felt uncanny to medieval Irish storytellers. They do not describe a rite anyone performed. Nicholas Rogers credits Samhain with Halloween's darkness and supernatural flavour, and with little else. | Pagan, real mood, not a rite; via Christian authors |
| Royal assemblies, feasts, tribute at Samhain | Irish tales and law texts | The óenach (assembly) at Tara every seventh Samhain, tribute paid at Samhain in Lebor Gabála, Samhain as a legal term day. This is the best-attested thing about pre-Christian Samhain, and none of it survives in Halloween. A quarter day for rents and hiring, which 1 November remained in Scotland, is the closest descendant, and nobody wears a costume to it. | Pagan, real did not carry over |
| Bonfires | early modern | Halloween fires are recorded in the Scottish Highlands, the Isle of Man, Wales and Ulster in the early modern period. They are absent from England, where 5 November took them after 1605. A fire on the first night of winter is easy to believe old, and a regional cluster in the Gaelic and Brythonic west is what descent would look like. But the medieval Irish texts put the druids' fire rite at Beltaine, 1 May, not at Samhain, and no record links the Halloween fires across the thousand years in between. | Plausible, unproven |
| Fortune-telling: apples, nuts, kale stalks, mirrors | 18th century | Burns's "Halloween" (1785) is the catalogue: pulling kale stalks to learn a spouse's shape, nuts burned in pairs, the blue clue of yarn thrown in the kiln, the apple eaten before a mirror. These are marriage divinations, and the same kinds of game ran on other nights (St Agnes' Eve, Midsummer). The "Roman goddess Pomona" story, that Romans brought apple games to Britain, has no Roman festival behind it. No ancient source gives Pomona a feast day. Lisa Morton's history rejects the link. | Plausible, unproven Roman link: unsupported |
| Going door to door: souling | 15th century | Soul cakes given at Allhallowtide in return for prayers for the dead in purgatory. Shakespeare has a character "puling like a beggar at Hallowmas" (The Two Gentlemen of Verona, 1590s). This custom is Catholic doctrine at a doorstep. The Reformation's attack on purgatory is what weakened it in England, though souling hung on in parts of the north into the 1930s. | Christian |
| Costumes: guising | 16th century, Scotland | Disguised visitors going house to house are recorded from 16th-century Scotland, at several winter festivals, New Year included, not only at Halloween. By the late 19th century, guisers in Scotland and Ireland carried turnip lanterns and took cakes, fruit and money. Ayr had a word for the masks by 1890: "false faces." The child's Halloween costume as a mass custom is North American and 20th-century. | Modern mumming itself older, not pagan-attested |
| Pranks, "mischief night" | 1736 | Recorded in the Scottish Highlands in 1736 and in Mayne's 1780 poem. In 1920s and 1930s America the pranks had turned into vandalism serious enough that towns organised parties and house visits to stop it. That is where trick-or-treating comes from. | Modern |
| Lanterns: turnips, then pumpkins | 19th century; 1837; 1866 | Hollowed turnips and mangel-wurzels with faces were common in 19th-century Ireland and the Highlands. "Jack-o'-lantern" meant a will-o'-the-wisp from 1658 and a night watchman later in the century. The Oxford English Dictionary's first use for a carved pumpkin is American, from 1837, and the first record tying the carved pumpkin to Halloween is from 1866. David Skal notes that no major 19th-century British chronicle of folk customs mentions carved Halloween lanterns at all. The "Stingy Jack" legend is a folktale, collected in the 19th century. | Modern |
| Trick-or-treating | 1917; nationwide 1930s–1950s | The phrase is first printed as "tricks or treats" in the Sault Daily Star, Ontario, on 1 November 1917. Variants appear across Ontario and Alberta in the 1920s, the first United States print use is 1928 (Bay City, Michigan), and the first national magazine use is 1939. Sugar rationing (1942–1947) stalled it. National children's magazines picked it up in 1947, Peanuts drew it in 1951 and Disney's Trick or Treat came out in 1952. The thing most people mean by Halloween is younger than television. | Modern |
| Witches, black cats, skeletons | late 19th–20th century as Halloween imagery | Witch belief is early modern and was condemned by the church, not carried by it. As Halloween decoration, witches and black cats spread through the American postcard and party-goods trade around 1900–1920. | Modern |
| "Samhain, Lord of the Dead" | antiquarian, 18th–19th century | Still printed in tracts warning against Halloween. No Irish source names a god called Samhain. The word names a feast or a season, and the medieval glossaries treat it as a word for summer's end. The god is an antiquarian invention, repeated by people who never read an Irish text. | Modern an invention, not a custom |
The story has authors and dates, which is the house's test for a human doctrine.
Rhys, a Welsh scholar, gave the Hibbert Lectures in 1886 (published 1888 as Celtic Heathendom) and developed the idea further in Celtic Folklore: Welsh and Manx (1901). He inferred that Samhain opened the Celtic year from Welsh and Manx folk practice of his own century. Hutton calls the evidence "flimsy." The Gaulish Coligny calendar, the one pre-Christian Celtic calendar we have, does not obviously start the year there.
Frazer took Rhys's New Year and added the dead: a pagan Celtic festival of the dead that the church turned into All Saints and All Souls. Hutton's summary is that Frazer reasoned from analogy: there was no record of such a festival, so he inferred one. The Golden Bough was one of the most widely read books in English for half a century. Its method was to find a resemblance and call it a survival, and it did the same to Christmas, to Easter and to the crucifixion itself.
Mid-twentieth-century Wicca built a calendar of eight sabbats, one of them Samhain on 31 October, and its writers took their history from Frazer. Revival paganism then taught the Victorian theory back to the public as ancient tradition.
Some evangelical Christians took the same Frazer story as a warning: the holiday is a druid rite to "Samhain, Lord of the Dead." So the neopagan and the alarmed Christian draw on one 19th-century source. Each has a motive to believe it, one for an ancient pedigree, the other for an ancient enemy. That shared motive is reason to check it.
This is the pattern TPS 76.0 found for Christmas: a claim about the ancient world that is really a claim from the nineteenth, which nobody checked because everyone wanted it to be true.
This is the part of the history closest to the house, and it is not the part anyone tells. New England's Puritans did not keep Halloween. Their reason was not that it was pagan. It was a saints' day, and saints' days were human additions to the calendar with no warrant in scripture. They treated Christmas the same way, and Massachusetts fined people for keeping it from 1659 to 1681. Their objection was the one the house uses on Lent and the councils (Not by Command): a feast with a date and a pope behind it is legislation, not revelation.
Late-18th- and early-19th-century American almanacs barely mention Halloween. It arrived with the Irish and Scots in the 19th century, the famine immigration above all, and became an American holiday between about 1880 and 1950. It went from courtship games to parties to pranks. Then towns fought the vandalism with organised trick-or-treating, which was what made it the biggest children's night of the year. So the holiday a family keeps on 31 October is mostly a 20th-century North American invention on a 9th-century Christian date. It carries a thin Gaelic sense that the night is uncanny, and possibly a Highland bonfire.
The Puritan test and the house's test agree here. Halloween is not commanded, so it is not worship, so the question "is it pagan worship?" does not arise for a family that keeps it as play. The household's actual criterion, from TPG 20.0, is whether a holiday does something for the children who keep it. On that criterion Halloween is one of the best holidays the culture has.
Nearly everything done on Halloween is first recorded between the 1400s and the 1950s, a thousand years or more after Ireland's last pagan generation. Trick-or-treating, pumpkin lanterns, children's costumes and the decorations are documented as new when they appear.
"Too modern" fits the customs, not the day. All Hallows' Even is the vigil of a feast first found on 1 November around 800 in Ireland and Northumbria, and made law across Francia in 835. Nobody wrote down why that day was chosen, and the Irish may have helped choose it. The holiday's name, its feast and its night-of-the-dead theme are Christian either way.
Medieval Ireland records Samain's name, date and uncanny mood, but no Halloween practice. The first documented Halloween is England's Catholic bell-ringing for the dead, and the first detailed folk Halloween is in Lowland Scots poems of the 1780s. What is really Irish is the 19th-century folk holiday that immigrants carried to America.
The earliest Irish stories treat Samhain night as the time when the otherworld is open. That sense is probably older than the church, survives in Halloween's mood, and is the one honest "pagan root." It is a feeling about the start of winter, not a rite, a god or a sacrifice.
Celtic New Year (Rhys 1886), festival of the dead (Frazer 1890), Lord of the Dead (antiquarian invention): three claims, all with dates and authors in the last two centuries, and all repeated by both the people who want Halloween pagan and the people who fear it is.
1. Absence of records is expected for an oral culture. Pagan Ireland wrote almost nothing, so a gap before 600 is what you would see whether or not customs survived. This is true, and it is why the page grades bonfires and divination "plausible," not "modern." It does not rescue the customs whose start is recorded as new, such as pumpkin lanterns and trick-or-treating.
2. The geography fits descent. Halloween fires and divinations cluster in Gaelic Scotland, Ireland, Man and Wales, the old Celtic-speaking west, and are weak in England. A regional substrate is a reasonable explanation. The alternative is that remote rural regions kept every old seasonal custom longer, Christian ones included.
3. The church did sometimes take over pagan dates and places. Gregory the Great told the mission to England in 601 to turn temples into churches and give the people feasts in place of their sacrifices (Bede, Ecclesiastical History 1.30). That is a real policy. But the church named its replacements, and no source says All Saints was one. The Irish calendars of about 800 also keep their weightier all-saints feast on 20 April, which a church setting out to replace Samhain would not have done.
4. The Irish may have helped set the date. Correction to this page's first version, which said Irish calendars kept all saints only on 20 April. The Félire Óengusso also puts the crowd of saints on samain, 1 November, and Hennig argued the date travelled from Ireland through Northumbria to the continent. If so, Samhain gave Halloween its slot in the year. Exhibit A2 sets out the evidence. The feast that filled the slot is still Christian.
5. Scholars disagree on how much Samhain shaped Halloween. Rogers gives Samhain the supernatural mood. Others (Foley and O'Donnell, 2008) treat Halloween as a purely Christian vigil. The page sits between them: one inherited mood, no inherited rite.
6. First recorded is not first practised. Folklore collecting began in earnest in the 18th century, so an 18th-century first record can hide an older custom. This is the strongest objection to "too modern," and it is why only customs documented as new are graded modern.
7. The Coligny calendar may show a pre-Christian Samon feast. A 2nd-century Gaulish bronze marks "three nights of Samon" in the month SAMON. If that month is the start of winter, a Celtic Samhain-type feast predates Christianity on the continent. Scholars are divided on whether SAMON falls in summer or winter, and a feast existing is not the same as its customs surviving.
8. Some sources here are secondary. Hutton's wording is quoted as other scholars and reference works quote it. The first-print dates (1917, 1928, 1837, 1866) come from the newspaper and dictionary citations as reported in the histories named below. This page has not read the original Irish manuscripts. Readers should check.
It licenses telling a relative that Halloween's name and date are Christian, that the night-of-the-dead theme comes from All Souls, that trick-or-treating is younger than their grandparents' grandparents, and that the "Samhain, Lord of the Dead" in the tract they forwarded is not in any Irish text. It licenses keeping Halloween as the house already does, as a children's holiday of roleplay and exchange, and adding to it, as TPG 20.0 proposes.
It does not license saying Halloween has no pagan connection. The Gaelic sense of an uncanny night is real and probably old. It does not license saying All Saints' Day is commanded, since by the house's rule it is a dated human feast like any other. And it does not license contempt for families who skip Halloween for reasons of conscience. The Puritans skipped it too, for a better reason than the one usually given now.
Method. Working page, first pass 2026-10-27. Each custom is dated by its earliest written record as reported in the standard histories, graded on whether a continuous line to a pre-Christian practice can be shown, and set against the conversion of Ireland (Patrick's mission traditionally 432; the island broadly Christian by c. 600).

Sault Daily Star, 1 Nov 1917; Bay City Daily Times, 1 Nov 1928; Doris Hudson Moss, The American Home, 1939. The page's first version (same day) said Irish calendars kept all saints only on 20 April; corrected in Exhibit A2 and counterweight 4 after checking the Félire Óengusso.
Corpus anchors. TPG 20.0 (Halloween as a model child-centred holiday; the proposed empathy ritual built into it); TPG 30.6 ("Halloween thrives while Lent languishes"); TPS 76.0 (the same question for Christmas); TP 35.0.1 (a dated doctrine is a human doctrine); TP 8.0 (commands have reasons); Not by Command (the Puritan calendar test applied to fasting).
Standing caveat. A working evidence file, not settled doctrine. The counterweights are printed because a reader who finds them first will trust nothing above them.
