* 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.

* "Franchise/Fallout" contains shades of this with few easily defined religions having survived tha atomic war. By the time of "VideoGame/FalloutNewVegas" and "VideoGame/Fallout4" the largest surviving faiths seem to be the Chruch of Atom that worships nuclear weapons and some variation of Christianity preserved by the NCR with all others being down to individuals groups. The majority of organized churches seen hold the view of praying to whatever gives the individual comfort rather then being faith specific.

* [[https://www.smbc-comics.com/comic/temple Generic Temple]] in ''Webcomic/SaturdayMorningBreakfastCereal]]'' allows its worshipers to pick and choose their own beliefs for the explicit purpose of psychological relief.

* [[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.

** The ({{contested|Sequel}}) 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.

* ''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.]]

* Scientism from ''VideoGame/TheOuterWorlds'' is a weird mix of Christian Scientist, Taoism, Confician Philosophy, and [[MegaCorp megacorporate]] CargoCult.

* [[https://www.youtube.com/watch?v=vXLtCsa6yy4 ''God's Gang'']] is a cartoon about an interfaith themed crime fighting superhero team.

* Invoked consciously by ''Film/{{Gandhi}}'': [[https://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!"]]
** He also mentions that it was common for him as a child attend religious services where the priest would quote from the Vedas, Qu'ran and Bible alike.

* ''Literature/HighSchoolDXD'' is largely a CrossoverCosmology, but still makes this trope out of Heaven and the Angel faction, which appear to be a broad-strokes amalgamation of every major Abrahamic religion. What makes this stand out is one character being a properly-researched Protestant, as contrast to the usual [[ChristianityIsCatholic all-pervasive Catholicism]]. [[WordOfGod The writer]] has stated this just made the whole mess much easier to keep track of, while [[WatsonianVersusDoylist the story]] explains that Heaven being more unified than its followers is classified information, as [[spoiler:GodIsDead and the faith-based mechanism Heaven gets its power from if already close to falling apart without Him,]] and revealing the truth could sink the faction entirely. Also, while Church-faction civil wars do drive a couple of conflict arcs, they're always Catholic schisms who know the truth or never have their denomination made clear.

* 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 Friedrich Nietzche and Thomas Paine.

* 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.

** The [[ProudWarriorRaceGuy 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).

* 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 UsefulNotes/{{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.]]

* 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.

* The "God Worshipping Society" of UsefulNotes/QingDynasty China mashed up elements of Protestant Christianity with Chinese folk religion, at the hands of Hong Xiuquan, who claimed to be the second son of the the Judeo-Christian God (and thus Jesus' younger brother), and also considered God to be the true Chinese emperor. This spawned the 14-year-long Taiping Rebellion, with the commonly estimated death toll being 30 million.[[note]]This would make it the deadliest civil war in history, and some estimates are ''much higher'' at up to a staggering 70 million, which would make it the second deadliest war in all of human history after UsefulNotes/WorldWarII.[[/note]]

->''"[Netty's] faith is omnistic: finding truth in every religion. She draws on American folk magic for blessing; works with Catholic saints; uses Buddhist house-clearing techniques to help Reddit friends with ghost problems.""''

* 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]].
* ''Series/{{Babylon5}}'' had a few varieties of these. Dr. Franklin followed a religion called Foundationism 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".

->''"Netty [...] grew up in a strict Hispanic Catholic household in New York in which dogma delineated womanhood, faith and the wider world. Her first foray into magic was at 13, after experiencing relentless night terrors and sleep paralysis that her faith could neither explain nor ameliorate. She followed a defensive meditation prescribed in a book -- ''The Occult Truth'' by Konstantinos -- and the terrors vanished. Today, her faith is omnistic: finding truth in every religion. She draws on American folk magic for blessing; works with Catholic saints; uses Buddhist house-clearing techniques to help Reddit friends with ghost problems.\\
Leaving traditional religious structures enabled her to take control of her spiritual development. "I found it very limiting," she says of Catholicism. "It's way too rigid. Every religion has spirituality, and they co-exist as it is, but everybody's concerned about a right or wrong answer -- can't everything just exist together? Can't saints and bodhisattvas both be great?""''

* [[https://en.wikipedia.org/wiki/Manichaeism Manichaeism]] claimed its prophet Mani as a successor to Zoroaster, Gautama Buddha, and Jesus.

* 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.

* ''Literature/SorryBro'': Ereduni was raised an Orthodox Christian like most Armenians. She also practices Wiccan magic though while taking communion and sculpting traditional cross statues, blending both.
