This is when a constructed fictional religion is clearly a mix of any number of real-world religions. An author will often use this by combining various interesting bits of existing religions, belief systems, and philosophies, and changing the names and places to make the new religion fictional. [[{{Wiki/Wikipedia}} That Other Wiki]] knows this process as it happens in RealLife as [[http://en.wikipedia.org/wiki/Syncretism syncretism]].

Differs from CrossoverCosmology in that this creates a 'new' cosmology from pieces of established idea systems. Popular in SpaceOpera and ScienceFiction as representative of alien cultures. A subtrope of NinjaPirateZombieRobot and a SisterTrope to CultureChopSuey. Can also be TruthInTelevision since there are few religions that don't share certain rituals or beliefs with other religions.

[[AnimeCatholicism This seems to come up a lot in anime fantasy settings]], though it could (and oftentimes appears to) just be a [[CriticalResearchFailure cultural misunderstanding of Western ideas and philosophies]] while substituting familiar concepts (like Buddhism and Shintoism) into the knowledge gaps. Also, sometimes in {{anime}}, instead of [[ChristianityIsCatholic All Christianity Being Catholic]], you'll see a mix-mash of ideas from various Christian denominations all pooled into a single faith. This probably has a lot more to do with the aforementioned CriticalResearchFailure, though.

Compare and contrast ChurchOfSaintGenericus, where the religious details could cover any number of faiths simply because they're left nonspecific.



[[folder: Comic Books ]]

* In ''ComicBook/{{Tintin}} in America''. It's a mixture of Judaism, Buddhism, and Islam, they claim they were the fastest growing religion, and want Tintin to become a member of them.
* The Church of Slag-Blah in ''ComicBook/BuckGodotZapGunForHire'' who are "militant agnostics" and celebrate a different religious holy day every day.
** Their definition of "religion" also bears questioning:
--->'''[[HookerWithAHeartOfGold Louisa Dem Five]]:''' I've caused so many moral dilemmas the Slag-Blah have declared me a religion!


[[folder: Film ]]

* ''Franchise/StarWars'': The Force, once described by Mark Hamill as "Religion's Greatest Hits!" The religion of the Force has strong elements of Buddhism, Jainism, Hinduism, Daoism and a bunch of other mystical traditions, with Christian symbology (the Jedi are [[KnightInShiningArmour Knights In Brown Robes]] and not for nothing is the hero named [[UsefulNotes/{{Christianity}} Luke]]).
* ''Film/TheMatrix'' movie trilogy is all over the place, embedding clear (in order of dominance throughout the series), Buddhist, Christian and Gnostic philosophies not only throughout the characters and plot, but including the music score, especially in ''The Matrix Revolutions'' soundtrack, which uses OminousLatinChanting, Sanskrit flavored, while the BigBad ridicules the hero about being a MessianicArchetype.
* Invoked consciously by ''Film/{{Gandhi}}'': "[[http://www.youtube.com/watch?v=GWwVMPrfzZc I am a Muslim and a Hindu and a Christian and a Jew and so are all of you]]!"
* TheFilmOfTheBook ''Film/WhatDreamsMayCome'' blends Eastern mystical concepts of reincarnation with Judeo-Christian concepts of monotheism, heaven and hell,[[note]]Although religions like Buddhism ''also'' have heavens/hells that one can be reincarnated into as reward/punishment.[[/note]] as well as an EpiphanicPrison for those that commit suicide. Dogs go to heaven, too.
* ''Film/PitchBlack'' has 'Chrislam' (which is a [[https://en.wikipedia.org/wiki/Chrislam real thing]]) pilgrims heading for the planet of New Mecca.

[[folder: Literature ]]

* The ''Literature/ThursdayNext'' series has the Global Standard Deity (GSD), a church that openly and shamelessly mixes and matches elements of various faiths apparently at will -- her brother "the Very Irreverent Joffy Next" is basically a hedonist. This is partly down to the fact that in this world literature is the major SeriousBusiness in people's lives, with sport, religion and television distant runners-up.
* The end of the ''Literature/{{Pendragon}}'' series has Ravinia, in which people see life in the rest of the universe (Halla) for the first time. This is not a religion in itself, but something that attracts people regardless of religion into one group. On the other hand, it divides people based on social class.
* The Church of God Awaiting in Creator/DavidWeber's {{Literature/Safehold}} series is an InUniverse example. It is a mash-up of real religions that was created for the purpose of putting ultimate power in the church's hands and [[MedievalStasis precluding the possibility of technological advancement]].
* The far future religions in the ''Franchise/{{Dune}}'' series are either this (i.e. The Orange Catholic Bible) or the CocaPepsiInc type (Zensunni). The CocaPepsiInc ones are the more numerous though (the Orange Catholic Bible ''seems'' to be more dominant in the first novel, but then a Zensunni branch ends up overrunning the known universe. There is also the fact that the Orange Catholic Bible was created to be the most universal holy text reasonably possible, not necessarily the most universal ''religion'' reasonably possible).
** The prequel novels show that the creation of the OCB was far from a peaceful and universally-accepted process (taking place less than a century after the end of the [[RobotWar Butlerian Jihad]]). In fact, the people who compiled the book nearly got themselves lynched by the angry mobs. They were only spared when TheEmperor intervened and granted them sanctuary in his palace. That is, until his young daughter caught one of them supposedly raping the Empress (said daughter would later start to suspect that the act may have been consensual). The Emperor then had all the translators publicly executed, making his daughter watch the consequences of her actions. It's not clear when that hatred for the OCB turned into nigh-universal acceptance.
* The ''Literature/{{Videssos}}'' books, being chockablock with {{Fantasy Counterpart Culture}}s, have lots of these. The religion of Videssos proper (the fantasy analogue of the UsefulNotes/ByzantineEmpire) looks a lot like UsefulNotes/OrthodoxChristianity (with bishops, monks, ecumenical councils, schisms over variations in the Creed), but the dualistic belief system is much more like Zoroastrianism (two powerful gods, one good and one evil, at war). There are heresies with variant understandings of the war (Videssians believe the good god is sure to win, Khatrishers believe the two gods are perfectly balanced, Namdaleni believe the gods are balanced but you ought to ''act'' as if you're sure the good god will win). The main other empire starts out as practically-Muslim (with belief in a single God and four supreme Prophets), but ends up being dominated by a diabolist religion that worships the evil Videssian god.
* In ''Literature/LifeOfPi,'' the title character manages to be a practicing Hindu, Christian, and Muslim all at once, to the confusion of most of the other characters. He was born a Hindu but chooses to simultaneously practice both Islamic and Christian rituals as he grows up. His stated reason is that he "just wants to love God."
* In ''The Unincorporated War'' by Dani and Eytan Kollin, the various religions in the Outer Alliance get together for a conference in order to come up with something like this. Mostly the Abrahamic religions but others as well. [[spoiler: Unfortunately it's interrupted by an attack from the United Human Federation resulting in slaughter.]]
* Creator/PeterFHamilton's [[Literature/TheNightsDawnTrilogy Confederation Universe]] has more a case of in''tra'' faith smoothies, with the various factions of Christianity and Islam reconciling their differnces and each forming a single religion.
* Daniele Bolelli's ''Create Your Own Religion'' is all about doing this on a personal level. The author's own belief system of preference seems to be a combination of Buddhism, Taoism, Native American spirituality and the philosophies of Freidrich Nietzche and Thomas Paine.
* In one of the ''Literature/{{Uplift}}'' novels a crazy alien evangelist preaches that a single Creator made humans without one of the sinful Galactic species [[UpliftedAnimal uplifting]] them, a species-wide virgin birth. And cites not only Jesus but also Moses, Buddha, Mohammad, Tipler, and Weimberg-Chang.
* Philip K. Dick was particularly fond of this: in several novels (notably ''TheDivineInvasion'') there was a merger between the Catholic Church and the Soviet Union in the backstory.
* Enigma Babylon One World Faith in the ''Literature/LeftBehind'' books, which consists of Roman Catholicism merged with various Christian sects that would not hold to fundamentalist doctrine (as defined by the books' authors and the Tribulation Force characters) as well as other world religions.
* ''Literature/StrangerInAStrangeLand'' has Valentine Michael Smith form a union of every single religion called "The Church of All Worlds," which eventually inspired a real religious community of the same name.
* The ''Janissaries'' by Creator/JerryPournelle has a world that has both Christians and pagans, with the pagan religion being very loosely based on Myth/ClassicalMythology. When a Christian nation enters into a political alliance with two pagan nations, a bishop has a rather convenient revelation that the two religions in fact worship the same god, resulting in the creation of a politically backed syncretic religion.
* ''Literature/ASongOfIceAndFire'' seems to do this with fictional religions in the cult of the Many Faced God. The temple includes shrines to gods from all over, and his adherents believe that all gods (or at least all death gods) are avatars of him. There's also some implication of the religion taking elements from other faiths in the universe in its theology and worship.
* Gaianism in Paul [=McAuley=]'s ''The Quiet War'' combines generic nature worship with Catholic ritual. It's "green saints" are similar to gurus.


[[folder: Live Action TV ]]

* Wayism in ''Series/{{Andromeda}}'' was this. It was mostly Buddhist 'peace in suffering' teachings, with a few other things thrown in. In universe it was created by a Magog who was taught the concepts of various religions to him by the human host he was [[FaceFullOfAlienWingWong spawned from]].
* [[Franchise/StarTrek The Klingon belief system]] seems to be an odd mish-mash of Shinto and Norse mythology, with a MessianicArchetype figure (Kahless) and a NayTheist quirk (they had gods, but killed them as too much of a bother) thrown in. Vulcan spirituality seems to have elements of Shinto ancestor worship within a predominant Buddhist philosophy, with 'logic' substituted for Dharma. The Bajoran faith which features prominently in nearly every episode of ''Series/StarTrekDeepSpaceNine'' may be the ultimate example of this trope, combining elements of all three Western monotheisms (Judaism, Christianity and Islam) together with Eastern Hindu/Buddhist mysticism (with the bonus that their gods are definitely real and occasionally show up to chat with the heroes). Plus, they once had castes like Hinduism. And a Catholic style leadership (The Kai and the Vedak Assembly lining up with the Pope and the College of Cardinals respectively).
* ''Series/{{Lost}}'' always favored the archetypal over the specific, and throughout its run contained references to many different religions and philosophies, hinting that there's some universal basis to all of them, even John Locke's personal shamanistic and prophetic belief system. The finale reinforces this by showing a stained glass window with symbols of Christianity, Judaism, Islam, Buddhism, Taoism and Hinduism on it, all radiating outward from one single source (that's also the same color as [[spoiler: the light at the heart of the island]]).
* ''Series/{{Firefly}}'' is a subtle example, as the only explicitly religious ceremony it shows is a funeral which combines Christian and Buddhist elements, which may just be Artistic License - Religion.
* ''Series/{{Babylon5}}'' had a few varieties of these. Dr. Franklin followed a religion that explicitly took parts they liked from all human faiths and meshed them together. There's also a TheMaker religion, a belief so generic that members of several different cultures take it up and integrate it into other faiths. We are also introduced to an order of Catholic monks who have made it their mission to find out all they can about alien faiths in order to "learn all the names of God".


[[folder: Music ]]

* Music/GeorgeHarrison's song "My Sweet Lord" features background vocals that begin by chanting "Hallelujah," gradually shift to chanting "Hare Krishna," and eventually become a Vedic prayer to Vishnu, all while the main vocal continues in the same prayer to "my Lord" (of course, Hindus also refer to their gods as "lords"-e.g. Lord Vishnu, Lord Shiva, etc.).


[[folder: Tabletop Games ]]

* The ''Handbook: House Davion'' sourcebook for ''TabletopGame/BattleTech'' details a religious movement in the Federated Suns called the "Unfinished Book Movement" which is a literal mash-up of a number of existing religions (most of which still exist elsewhere in the setting, even within Davion Space) into a single entity with a single, collected, holy scripture. Apparently it's becoming quite a major player in the realm by the time the book was set.
* InUniverse for ''TabletopGame/{{Warhammer}}'' and ''TabletopGame/Warhammer40000'': While there are four Chaos Gods (representing the emotions of rage, desire, hope and love) and many of their worshippers devote themselves to a single one, it's also possible to worship them as a pantheon as a follower of Chaos Undivided.
* In ''TabletopGame/LegendOfTheFiveRings'' the state religion of Rokugan, a FantasyCounterpartCulture of Japan, is Shinseism, a fusion of Japan's two most common faiths (Shinto and Buddhism), plus Taoism.

[[folder: Video Games ]]
* ''VideoGame/{{Solatorobo}}'s'' Oshilasama seems to be one part the Buddhist-Shinto amalgam common to Japan and one part FunctionalMagic. Oh, and something about an evil dog-god who loses his powers if you turn his statues upside-down.
* ''VideoGame/OracleOfTao'' has a strange mix of Shintoism, Taoism, and Christianity. They call it Aiken (based on Japanese ''ai ken'', not Clay Aiken). It's basically very heavily into nature and love (and ancestor worship).
* In ''VideoGame/EscapeVelocity: Nova '', the Church of Krim-Hwa is this in-universe.
* The heroine of ''VisualNovel/HatofulBoyfriend'' describes herself and her family as Shin-Buddhist, but is perfectly willing to celebrate Christmas if given the opportunity. This is pretty much [[UsefulNotes/ChristmasInJapan exactly how real Japanese people treat Christmas]].
* In ''VideoGame/CivilizationBeyondEarth'', Kavitha Thakur of the [[{{Egopolis}} Kavithan Protectorate]] is some kind of religious leader, though the tenants of her belief system are mostly left ambiguous. However, an in-game quote from one of her prayer devotionals unambiguously reveals how mish-mash the faith's mythology is.
-->''[[OurAngelsAreDifferent Seraphim, Cherubim,]] [[UsefulNotes/{{Hinduism}} Devas, Fravashi,]] and [[UsefulNotes/{{Zoroastrianism}} Yakshas]], extend thy arms to cover us, hear us and convey our prayer to [[TheMaker the Lord Creator]].''
* ''VideoGame/{{Siren}}'' has the local religion of Hanuda, which combines village and Japanese folklore with Christianity and worship of an "alien god" [[spoiler:who the locals ate during a famine and whose new physical incarnation serves as the final boss of the game.]]


[[folder: Web Comics ]]

* In ''Webcomic/KoanOfTheDay'', the guru is an amalgamation of [[http://www.koanoftheday.com/27/ Jesus]], [[http://www.koanoftheday.com/56/ the Buddha]], and [[http://www.koanoftheday.com/42/ Socrates]].
* In an ''Webcomic/{{xkcd}}'' [[http://xkcd.com/900/ strip]], this discussion takes place:
-->“I’m the kind of Christian who only goes to church on Christmas and Easter, and spends the other 363 days at the mosque.”
--> “… I don’t think that’s a thing.”
--> “Our rabbi swears it’s legit.”
* The Eastern Dragon in ''Webcomic/{{Sinfest}}'' is a living embodiment of all East Asian religions.
* Pangaeism, the most politically correct religion ever, is briefly mentioned in ''Webcomic/LastRes0rt'', apparently they have a minor holy war every time a new species is contacted and the scripture needs to be revised to include their mythology.
* In ''Webcomic/{{Freefall}}'' omniquantism is the idea that if God is omnipotent and all things are possible, then it is possible that all religions are correct simultaneously. One in three AIs [[LogicBomb lock up]] after hearing the concept, Florence managed to make sense of it [[http://freefall.purrsia.com/ff1400/fc01388.htm though]].


[[folder: Web Original ]]

* Sanshinto or Tritheism in ''{{Literature/Tasakeru}}'' is based primarily on Shinto, but has elements from Greek, Roman, and Norse mythology. The species' differing beliefs draw from ''everywhere'', even, [[WordOfGod according to the author]], the Franchise/CthulhuMythos.
* The Literature/ChaosTimeline has the Indian Chandramoorthy develop his own religion, which combines elements from Hinduism, Islam, Catholicism and the classical Greco-Roman religion.
* Gamzee's religion in ''{{Webcomic/Homestuck}}'' seems to be based around fundamentalist and Rapturist Christianity, with a little Islam for flavour (he gets [[BerserkButton very upset]] about seeing video depictions of his Messiahs), and perhaps with a little Judaism (his ancestor was responsible for the persecution of the [[CrystalDragonJesus Troll Jesus]]), mixed up with [[TheStoner stoner]] / [[NewAgeRetroHippie hippie]] culture, and then all applied to {{Juggalo}} fandom. A parody, obviously. [[spoiler: WordOfGod is that is was inspired by an EldritchAbomination and his ManipulativeBastard [[TheDragon Dragon]], arguably making it a ReligionOfEvil.]]
* Parodied in Website/GaiaOnline by the Church of Non-Specific Worship.
** One plotline may have [[FridgeBrilliance incidentally justified this]] by showing that not only do {{Physical God}}s exist in Gaia, they're numerous and varied enough to make categorization and organized religion difficult.


[[folder: Western Animation ]]

* ''WesternAnimation/{{Futurama}}'' plays with a somewhat joke-y version of this trope in the First Amalgamated Church, headed by Father Changstein El-Gamal. Supposedly created from the merging of major 20th Century religions - Christianity, Judaism, Islam, Hinduism and Buddhism as well as agnosticism, and the logo shows it. Differs from more serious examples in that part of the joke appears to be that the Church doesn't have even a semi-coherent belief system and mostly just tries to be as generically 'spiritual-ish' as possible.
-->'''Father Changstein El-Gamal:''' Dearly liked, we stand here before one or more gods, or fewer; to join this couple in pretty good matrimony. If anyone objects to this union, may they speak now, or forever hold their peace; or do something else.
* The only thing you can definitively say about Reverend Lovejoy's church in ''WesternAnimation/TheSimpsons'' is that it's some variety of Protestantism. In an episode where Bart and Homer convert to Catholicism, the Rev describes the One True Faith as being "the Western Branch of the Reformed Church of American Presbo-Lutheranism".
** Ned Flanders confesses in one episode that he's "kept Kosher to be on the safe side."


[[folder: Real Life ]]

* Certain Unitarian Universalist congregations can end up like this. Since [=UUism=] rejects the idea of central dogma in favor of emphasizing the value of spiritual community, nothing stops any individual from being a Christian, Jew, Muslim, Buddhist, Hindu, Pagan or even atheist/agnostic and still a practicing [=UU=]. It's not too far from the truth to joke that [=UUs=] begin their prayers with "To whom it may concern..."
* Messianic Judaism, which combines the main tenets of Judaism with a belief in Yeshua, or Jesus as Messiah. Most Jews consider messianics to be simply Christians by another name, or at worst, disguised proselytizers.
* The proper term for this trope is [[http://en.wikipedia.org/wiki/Syncretism Syncretism]]. As you can see, there are enough examples of it in RealLife.
* Some Anglicans (Church of England) embraced Catholic spirituality and outward elements (i.e. Mass, the rosary, vestments) while still remaining with the Church of England. They're called Anglo-Catholics.
** In the 19th century, it was very common among scholars of world religions to seek a complete understanding of God by bringing the knowledge of all religions together to create a unified whole. While certainly admirable, religious authorities of all religions were mostly unimpressed and didn't share the belief that other religions had anything to contribute to "their" already perfect models.
* There independent/noncanonical[[note]]Eastern Orthodox term for unrecognized Orthodox Church that isn't part of full communication with Main Eastern Orthodoxy[[/note]] Eastern Orthodox denomination named [[https://en.wikipedia.org/wiki/Evangelical_Orthodox_Church Evangelical Orthodox Church]] that blends with Protestant (mainly Evangelical and Charismatic[[note]]which this part of what remains of [[https://en.wikipedia.org/wiki/Shepherding_Movement Shepherding Movement]][[/note]]) elements and their current mission is to spread their religious beliefs through the world, and they are [[https://www.evangelicalorthodox.org/who-we-are currently 120 churches under EOC and most them are in Burundi]].
* [[http://caricatura.ru/daily/korsun/360/ This]] (text: "Basics of religious cultures and secular ethics") was a reaction on the introduction of this experimental "obligatory facultative" school course -- which, obviously, managed to unite ''everyone'', if only in condemnation of this offense.
* Very common in East Asian cultures. While Judaism, Islam, and several modern denominations of Christianity forbid syncretism, major East Asian religions like Shintoism, Buddhism, and Taoism have no such restrictions.
** Similarly, during the Middle Ages and even into the early 20th century, a form of Christian syncretism was common enough among the educated classes. Greek and Norse and Celtic and other ancient European pagan gods were often reinterpreted as Christian angels who had been mistakenly worshiped (whereas the gods of other parts of the world were often assumed to be demons who had been mistakenly worshiped) or reinterpreted as Christian saints who had been deified against their will.
** The Literature/MuneShinri, a web-based religion is a syncretic blend of Taoism, Shintoism, and Christianity. If Christianity forbids syncretism, and Taoism allows it, [[LogicBomb does that make it right or wrong]]?
* The Baha'i faith is arguably an example of this. It basically recognizes the prophets of a wide range of other religions (including Moses, Buddha, Jesus, Muhammad, and others) and claims that they all founded "the religion that was necessary (and possible) at the time", in a scheme for humanity's collective evolution, whereas Baha'i is (obviously) the appropriate religion for our own time. The actual belief system seems to be a syncretic mish-mash of (primarily) the monotheistic religions, with all the nasty bits taken out and a pinch of rationality and egalitarianism thrown in.
* The currently under-construction [[http://en.wikipedia.org/wiki/Temple_of_All_Religions Temple of All Religions]] in Russia aims to offer services for, well, [[ExactlyWhatItSaysOnTheTin all religions.]]
* Historically, this was the case for most non-monotheistic religions. An ancient German could adapt very well to Celtic, Tengri, Greek, or any other gods you could name. Exactly what the relationship between the various pantheons was depended on the priests, but most laity simply accepted that AllMythsAreTrue until their local priest told them otherwise.
** It helps that polytheistic pantheons often included the same basic archetypes (LoveGoddess, WarGod, patriarch deity in the sky etc.) and thus could easily be mashed together by explaining the foreign gods as alternate names for your own pantheon, as the Romans were particularly fond of doing, especially with their WarGod Mars, whom they believed themselves to be descended from.
*** According to historians the Roman, Greek, and other nearby faiths ''really are'' different branches of an earlier [[https://en.wikipedia.org/wiki/Proto-Indo-European_religion Proto-Indo-European religion]] as they had developed after the conquerors merged with local peoples and developed in isolation over centuries. Calling them alternative names for the same god is, more or less, true.
* Chapels in public facilities such as hospitals or airports have to accommodate anyone who wants to visit and pray, regardless of their religion. So they can become like this simply out of necessity-- if four patients' families are Muslim, Hindu, Catholic, and Protestant, it can make for a rather eclectic prayer service.
* Interfaith families often practice a mix of both parents' religions. A Jewish/Christian family, for example, might celebrate both Christmas and Hanukkah.
* This concept actually played quite an important role in initially winning over the Turkic and Mongol tribes to Islam, as the belief in Tengri was close enough to an Abrahamic monotheism that Turkic tribes such as the Volga Bulgars were able to look upon Islam and see a basically more refined version of their traditional religion.
** The Mongol ruler Ghazan of the Ilkhanate also converted to Islam and argued that his ancestors' veneration of Tengri was actually a form of Proto-Islamic religion.
** Also employed in the Dastans of Dada Korkut, a collection of sagas regarding Oghuz Hakaan, the mythical father of the Turkic peoples, where it is said that Dada Korkut (a figure similar to Merlin, or Odin) is said to have journeyed to Madinah where he spoke with Muhammad (PBUH) and accepted Islam, carrying that religion back to his people in the steppes. Over time, that belief in Islam was misinterpreted as the worship of the sky god Tengri. It's quite clear that this was added by Turkic chroniclers some time after their conversion to Islam in order to mitigate their pagan past.
** This trope is probably also why Turkic-speaking Muslims tend to use the word "Tengri" (which is really just a generic term for god, like the Greek Theos, the Latin Deus or the Nordic tyr) along with the preferred Arabic "Allah" to refer to God.
* The conversions of many formerly pagan areas to Christianity resulted in a lot of this.
** Mexico's [[https://en.wikipedia.org/wiki/Day_of_the_Dead Día de Muertos]] combines the Catholic All Saint's Day with an Aztec festival.
** South American Catholics often practice what were originally Inca religious festivals. For example, the parades with the statues of the Holy Family and major saints were originally done with the mummies of Inca kings.
** What little we know of Slavic pagan beliefs comes mostly from extrapolation backwards from records of Slavic/Christian syncretism. The Slavs seem to have initially taken Christianity as simply an ''afterlife'', while still paying obeisance to pagan spirits in day-to-day life.
** Several Afro-Caribbean faiths such as Santeria mix Catholicism with the native religions of imported African slaves (Yoruba in the case of Santeria).
* There is a lot of debate over whether Christmas originated as a syncretic co-option of pagan celebrations such as Saturnalia, Dies Soli Invicti, and Yule. While today this is mainly brought forward by neo-pagans as to argue that it was a plot to suppress their own faiths, historically this argument was primarily used by Protestants to denounce the 'impurity' of Catholicism. Prior to the mid-18th century (and in places, well into the 19th), most Protestant sects rejected all religious holidays except Easter (and even then often preferred to called it the Celebration of the Resurrection, as the name 'Easter' was seen as a syncresis), and went to great lengths to reject Christmas and Halloween in particular. This even reappeared in the 20th century among number of Christian sects and offshoots, especially those in the Charismatic and Millenarian movements.
* This trope was - partially - the reason why Japan was so eager to convert to Buddhism. Before that, gods were treated as mons - each clan had its own, and the power of each ''kami'' was closely tied with the family's standing. So, when Buddhist missionaries from Korea started to preach about this "Buddha" - who's said to be stronger than everything else - some people were more then eager to adopt him as their personal OlympusMons.
