-->''"With regard to heretics two points must be observed: one, on their own side; the other, on the side of TheChurch.

TheHeretic is a traitor to TheChurch and/or its {{Canon}}. Most commonly, he was once a member of its congregation or even its [[GoodShepherd clergy]] but got officially excommunicated for propagating beliefs that go against TheChurch's official dogma. Often, the Church sends out [[KnightTemplar Knights Templar]] to [[KillItWithFire Kill Them With Fire]] along with [[BurnTheWitch witches]]. Just being a heretic doesn't mark you evil by default: A heretic to a SaintlyChurch is often ChaoticEvil, but a heretic to a CorruptChurch or a PathOfInspiration may well be a DefectorFromDecadence.[[EvilVersusEvil Or just as bad as them.]]

To qualify as a heresy worthy of condemnation, the "heresy" should have an intrinsic connection to doctrines of the church in question. Someone who merely disagrees with the Church as an outsider is not a heretic - for instance, Hypatia of Alexandria. Wiccans and Buddhists are not considered "heretics" to the Catholic religion, but Padre Ned Reidy was put on trial for heresy.

The word "heretic" is from a Greek word meaning "to choose," so a heretic can be thought of as a person who chooses his own path. Much like YourTerroristsAreOurFreedomFighters in the political realm, those whom the Church labels "heretics" often claim that they're actually "reformers" or "purifiers". Christian theologian Irenaeus popularized the word heresy in the Christian world in his anti-UsefulNotes/{{Gnostic|ism}} tracts. Multiple heretics often form a {{Cult}}.

[[folder: Anime ]]

* Lenard and Elfetine's sect in ''LightNovel/ScrappedPrincess''. However, their "heresy" [[spoiler:was ''provoked'' by Lenard, who is a (overly ambitious) cleric himself, in the first place]].
* Heresy is a common charge leveled against people in ''Manga/{{Berserk}}'', particularly by those who serve the [[CorruptChurch Holy See]]. The Count from the third major manga story uses the charge of heresy to get himself people to eat, being an Apostle. And Mozgus in particular is [[KnightTemplar very]] [[ColdBloodedTorture much]] merciless in dealing with those who he considers heretics. [[EvilVersusEvil The true heretics themselves (at least Slan's cult) are not much better]].
* Arachne from ''Manga/SoulEater'' is described as a "heretic Witch" because of the way she created the original magical Weapons features in the series, namely, by taking a normal human soul, a weapon, as well as the Soul of her fellow Witch (holding the power of transformation). Thus, she's hunted not just by the good guys but her fellow Witches.
* ''LightNovel/ACertainMagicalIndex'':
** Creator/AleisterCrowley was once one of the greatest sorcerers in the world, but then he decided to defect to the Science Side. Given that there is a secret MagicVersusScience war going on, he's become one of the most hated figures in the Magic Side.
** Richard Brave is a sorcerer who wields a FlamingSword called Lævateinn. The Magic Side declares him a heretic because the sword uses a combination of magic and science to work instead of pure magic. In response to the Magic Side dissing his finest creation, Richard declares his hatred of the Magic Side and tries to get revenge.


[[folder:Comic Books]]
* In ''ComicBook/WhiteSand'', the non-Sand Masters alternate between calling them heretics and infidels, depending on how fanatic they are themselves, because of Masters' practice of magic.


* In ''Film/{{Kenau}}'': what a lot of Dutch people are, according to the Spanish. The prosecution of protestants is the main reason the Low Countries rose in revolt against Spain. It is also the reason why Kenau's daughter is burned, and triggers her anger against the Spanish so much that she goes from RefusalOfTheCall to JumpedAtTheCall in no time.


[[folder: Literature ]]

* ''Literature/TheNameOfTheRose'', by Creator/UmbertoEco, entirely revolves around the theme of the thin line between orthodoxy and heresy, and what happens when people cross it.
* Nicholas Harpole in ''[[Literature/TheCompanyNovels In The Garden of Iden]]''.
* In Creator/DavidEddings' ''Literature/TheRedemptionOfAlthalus'', one of [[TheAtoner Althalus]]' major enemies is a "defrocked" priest.
** From the same author, there's recurring villain Martel in ''Literature/TheElenium'', a former [[ThePaladin Church Knight]] who turned to the worship of the [[GodOfEvil Dark God Azash]] and committed various atrocities since.
** Zedar the Apostate of ''Literature/TheBelgariad'', who started as one of Aldur's disciples and eventually switched sides and signed on with Torak.
* The Church in the ''Literature/{{Safehold}}'' series brands the entire nation of Charis as being heretics, mainly because they had the gall to survive the Church's attempts to obliterate them out of sheer paranoia. So far, despite having called down a holy war upon the Charisians, they have yet to learn that many of the leaders of Charis really ''are'' heretics, although the heresy they believe in (That the Archangels were not really divine messengers) is actually true.
* In the ''Franchise/{{Disgaea}}'' [[LightNovel/DisgaeaNovels novels]] we meet [[OurAngelsAreDifferent angel]] [[Characters/DisgaeaNovels Ozonne]] who propagates beliefs that go against [[FluffyCloudHeaven Celestia's]] official dogma and is considered to be a heretic, but she is not excommunicated for it because the [[BigGood big boss]] [[PhysicalGod Seraph Lamington]] want to let heretics run free.
* The Preacher in ''Literature/ChildrenOfDune'' certainly counts as this. He wanders the cities and settlements on the planet Arrakis, speaking out against the religion that has grown around the late Paul Atreides and his sister Alia. Of course it turns out that [[spoiler:the Preacher actually ''is'' Paul, having walked blind into the desert several years before, thus essentially excommunicating '''himself''' from the dogmatic power structure that he had begun to hate.]]
* The Damned One is the history's greatest heretic in ''Literature/ArciaChronicles''. The twist in his case is that he is actually [[spoiler:St. Erasti, one of the most (if not ''the'' most) revered saints of TheChurch. This knowledge was so dangerous that TheChurch [[WrittenByTheWinners erased all connections]] between St. Erasti and the Damned One from history after his defeat]].
* Oelita, the Gentle Heretic, in ''Literature/CourtshipRite'', preaches against cannibalism and the belief that the moving light in the sky is a God. When our heroes are told of her by the clan leader, they assume they're going to be sent to kill her, and are shocked to learn that they're being ordered to marry her, and bring her congregation under Kaiel influence.
* Lots of this in the ''''Literature/TalesOfTheBranionRealm'''' series, which features a divine royal family whose monarch is a GodInHumanForm, the Vessel of the Living Flame.
** Book 1: [[RebelPrince A prince rebels]] against his mother, which given her status is both heresy and treason.
** Book 2: A Seer priest is part of a conspiracy to murder the Vessel, repents, and joins the Heir's protectors. The leader in charge of this RagtagBunchOfMisfits follows an entirely different faith, and his own God has ordered him to protect the Flame's Vessel -- possibly to ensure that its own followers are treated better in the Flame's country.
** Book 3: The Vessels themselves are heretics, having converted to a different religion and [[SealedInsideAPersonShapedCan trapping the Flame within their own bodies]]; the protagonists [[SaveYourDeity rescue It]] by [[StalkerWithATestTube seducing the Vessel]], having his firstborn son and raising him to kill his father -- also heresy, since this is like killing Jesus to free God from his human prison.
** Book 4: The protagonists are a heretic cult, trying to give the other three ElementalPowers their own avatars.
* High Priest Rheaesi in ''Literature/TheWillBeDone'' zig-zags it a bit; he's not ''technically'' a heretic, but the Church pretty much views him as such, and he gets [[PublicExecution executed]] in the end.
* ''{{Literature/Discworld}}'':
** The Omnian church indegenerated into this from its original purpose. Discworld gods need belief to survive, but as their religion gets more and more elaborate, people believed in the rituals and ceremonies more than the god itself, until Om was almost starved and the church became a totalitarian nightmare, with a special Quisition being formed to root out heretics in their own fold. They they started looking for heretics (and witches) abroad, such as those who might preach ridiculous nonsense like the world being flat and carried on the back of a giant turtle, when every good Omnian knows the world is round. ''Discworld/SmallGods'' shows how they finally got out of this mindset thanks to Om's last true believer (the book has simultaneously been called an attack on, and a defense of, Christianity). The later ''Discworld/TheScienceOfDiscworld IV'' features an unreconstructed Omnian [[TheFundamentalist fundamentalist]] who comes very close to accusing ''Om'' of heresy.
** As mentioned in ''Discworld/TheFifthElephant'', dwarfs think they have no religion, but "being a dwarf" ''is'' a religion. ''Discworld/{{Thud}}'' introduces the deep-down grags, who seem to believe almost all dwarfs are heretics of this religion. By ''Discworld/RaisingSteam'', they are described as being well on their way to suspecting ''each other'' of heresy, based on any form of dissent whatsoever.

[[folder: Live Action TV ]]
* The reformation had just started at the start of ''Series/TheTudors'', but gained momentum as the series went on. Because of that the [[LoadsAndLoadsOfCharacters list grew ever longer]]. Here goes: [[FemmeFatale Anne Boleyn]], [[EnsembleDarkHorse Thomas Cromwell]], [[CrouchingMoronHiddenBadass Archbishop Cranmer]], Thomas Boleyn, [[TheWomanWearingTheQueenlyMask Catherine Parr]], [[GirlInTheTower Anne Parr]], [[MagnificentBastard Edward Seymour]], [[MagnificentBastard Anne Stanhope]], [[AllGirlsWantBadBoys Thomas Seymour]], [[PutOnABus The Duchess of Suffolk]], [[CoolTeacher Kate Ashley]] and [[OneSceneWonder Anne Askew]]. Some of them suffered for it, all the others at least lived in fear of discovery.
** [[WiseBeyondTheirYears Elizabeth]] and [[AChildShallLeadThem Edward]] are also raised this way.
** During the course of the series quite a few minor characters got burned and tortured for this reason as well.
* The Resistance movement in the pilot of ''{{Series/Lexx}}'' were known as the Heretics against the Divine Order, with their leader Thodin being the Arch-Heretic.

[[folder: Tabletop Games ]]
* ''TabletopGame/{{Warhammer 40000}}''[='s=] [[ChurchMilitant theocratic]] [[TheEmpire Imperium of Man]] has a saying: "light your way in the darkness with [[BurnTheWitch the pyres of burning heretics]]." The civil war that almost destroyed it after its founding and put the GodEmperor on life-support is labeled the Literature/HorusHeresy, there's an entire Ordo of the [[StateSec Inquisition]] devoted to rooting out heresy, and being executed for heresy is [[EverythingIsTryingToKillYou just one of the many ways to die in the 41st millennium]]. Some would say this can be [[{{Flanderization}} exaggerated]] into an overused {{meme|ticMutation}}, but that would be- "HERESY!" '''*[[BoomHeadshot BLAM]]*'''
** Of course, in this case they have a point: the Chaos Gods reward such activities as bloodshed, betrayal, hedonism, and spreading disease. Faith in the Emperor is just about the only defense Imperial citizens have against Chaos.
** The Imperium is just so ''big'' that the more realistic Ecclesiarchs have given up on ever achieving a uniform Imperial Cult, and must tolerate Him on Earth being worshiped according to different worlds' customs - Humanity's unifier made divine, a sun deity, the Omnissiah, the Allfather, etc. But at the same time, groups like Genestealer Cults, to say nothing of covens dedicated to the Dark Gods, are quite capable of masquerading as properly pious Imperial citizens until they're ready to sacrifice a planet to their dread masters. As a result, the Inquisition gets to spend a lot of time determining which religious groups fall within an acceptable level of deviance, and which need to be burned at the stake. As a rule, it errs on the side of caution.
** Ironically, the Imperial Cult was founded on the teachings of Lorgar, Primarch of the Word Bearers and the ''first'' Primarch to fall to Chaos -- the very first heretic.
** Not so ironically, the Imperial Cult ''really is heresy'', because the Emperor himself preached an [[FlatEarthAtheist Imperial Truth of science, rationality, and enforced disbelief in the Warp]].
** There are also heretics who deviate from the Imperium's ''other'' orthodoxy, the Cult Mechanicus. These "hereteks" usually start out as tech-priests who chafe under the Cult's strict restrictions on innovation and study of Xeno technology, and start experimenting with new designs and reverse-engineering captured alien tech, fully intending to better mankind through their work. This being [[CrapsackWorld 40k]], there's some ''very'' good reasons this things are forbidden, and most hereteks end up [[JumpingOffTheSlipperySlope taking a flying leap off the slippery slope]] sooner or later and going full over to Chaos, if they don't get themselves killed first. And if that wasn't enough, there's a very good chance they (unknowingly) ''are'' heretics- the Omnissiah is supposed to be an aspect of the GodEmperor, but it's strongly hinted that it's actually a C'tan CosmicHorror known as the Void Dragon, who has power over machines. So while the lower members of the Mechanicus are always happy to discover Necron tomb worlds and poke around until the Necrons wake up, the higher-ups know perfectly well what they're doing.
** The {{Player Character}}s of ''TabletopGame/BlackCrusade'' are Chaos followers, and books always refer to them as "the Heretics".
* Seen every now and then in ''TabletopGame/{{Eberron}}'' concerning the [[CrystalDragonJesus Church of the Silver Flame]]. Occasional Dark Six cults might qualify as this within the Sovereign Host.
* Anyone from ''TabletopGame/{{Exalted}}'' working with the Anathema (that is, anyone working with your player character).
** There is a growing number of these in [[EternalEngine Autochthon]]. And sometimes they are ''right''.


[[folder: Video Games ]]

* The eponymous character from ''VideoGame/{{Heretic}}'', of course. The Heretics in question were the Sidhe elves, the only race of beings not subject to the [[{{Brainwashed}} sorcerous mind control]] of the [[BigBad Serpent Riders]], and thus targeted for extermination by their minions.
* The Heretic Leader from ''VideoGame/{{Halo 2}}'', an Elite who learned the truth about the "Great Journey" from 343 Guilty Spark and tried to warn the rest of the Covenant. The Arbiter is also branded a heretic at the beginning for his failure in [[VideoGame/HaloCombatEvolved the previous game]], but that's really just an excuse to have him executed for his failure. [[spoiler:He abandons his own religious beliefs after discovering the truth about the Covenant and ends up leading a splinter faction which allies with the "heathen" humans.]]
* Ramza from ''VideoGame/FinalFantasyTactics'' gets branded as a heretic when he runs afoul of their AncientConspiracy and kills a (demon-possessed) bishop in self defense. On the other hand, Olan Durai is also burned at stake for trying to reveal the truth behind The Lion War and Ramza's unsung heroism.
** However, both appear to have been VindicatedByHistory by the time of ''VagrantStory'''s events later in the Ivalice continuity.
* Billy from ''VideoGame/{{Xenogears}}'' rejects the doctrines of his church once he learns of its sponsorship and purpose.
* Pellegri from ''VideoGame/{{Xenosaga}}'' stops just short of accusing her superior, Margulis, of heresy when he questions the authority of Lord Heinlein.
** On that note, Shion and Jin, who both are likely to have extensive ties to the Ormus religion - physically beat the crap out of '''UsefulNotes/ThePope''' at the end of ''Episode II''.
* Yuna becomes a heretic in ''VideoGame/FinalFantasyX'' when she resolves to reject the teachings of Bevelle and fight Sin to destruction.
** Happens to quite a few people in that game, notably the Crusaders being excommunicated for their use of machina, despite their perfectly good intentions and their continued belief in Yevon.
*** Not to mention the clergy actually backed the attempt to use machina to fight Sin. As soon as it failed, they pretended otherwise.
* Nero rejects the teachings of his church to save his lover, Kyrie, in ''VideoGame/DevilMayCry 4''.
* In ''VideoGame/MedievalIITotalWar'', regions where your faith isn't overwhelmingly dominant may spawn Heretics, or even convert a Priest you have stationed there to heresy. Since Heretics spread heresy and cause religious unrest, it's a good idea to have your Priests subject them to trials and [[BurnTheWitch burn them at the stake]]. If you're Catholic and you ''don't'' deal with Heretics, UsefulNotes/ThePope will send [[DemonicSpiders Inquisitors]] to your lands to start examining family members.
* Byakuren Hijiri from ''VideoGame/{{Touhou}}'' is a heretic by the virtue of being compassionate to the {{Youkai}}. In this settings, the very presence of Celestial beings can harm Youkai regardless of either sides' morality.
** Before that, there was Rikako Asakura, who was branded heretical for believing in science over magic.
* In ''VideoGame/MassEffect2'', it is revealed that the Geth the player had been fighting in ''VideoGame/MassEffect1'' were actually a fanatical splinter group called Heretics by the True Geth. Making up about five percent of the total Geth population, Legion emphasises that the Heretics ''chose'' to worship the [[EldritchAbomination Reapers]], instead of upholding the rather non-religious notion of self-determination of the True Geth.
* In ''VideoGame/CrusaderKings 2'', characters can adopt a variety of historical heresies. They tend to be loathed by anyone from the main religion, and imprisoned and forced to convert back. Unless a very powerful king adopts the heresy, [[NotSoDifferent in which case the same thing typically happens to the orthodox faithful]].
** The ''Sons of Abraham'' expansion for the game gives heresies the ability to supplant their parent as the mainstream faith, reducing the old beliefs to being seen as heretical themselves in the process. The earlier ''Legacy of Rome'' expansion allowed the Great Schism to be mended by a sufficiently successful still-Orthodox Byzantium, reducing Catholicism to a heresy of Orthodoxy.
* In ''VideoGame/TheElderScrollsIIIMorrowind'', the Dissident Priests were heretics to the Tribunal Temple, disputing several points of dogma (though this appears to have been partly a response to being persecuted for questioning Temple ''policy'', which isn't exactly heresy even if the Temple called it that). The Tribunal Temple also persecutes the Nerevarine Cult as heretics (technically they are, just not really of the Temple, seeing as they developed in parallel in response to the same event and from the same source religion. It's actually the ''Temple'' who made the most radical changes of dogma, the Nerevarine Cult just explained away the new gods as false gods and added in a messiah figure). [[spoiler: Both of those change towards the end of the main quest, with the Dissident Priests acknowledged as having had a point with much of what they said and the Nerevarine Cult recognised as being right about the messiah figure thing, both by one of the gods of the Tribunal himself.]]
*** Actually subverted in the case of the Nerevarine prophecy -- while the Temple considers it a folk superstition and persecutes the Ashlanders who believe it, when you actually show up and start fulfilling the prophecy, you get a letter from the local Archcanon. You see, they're not sure if you're a legitimate reincarnation of St. Nerevar ... so they're going to do their damnedest to try and kill you, as a sort of test. If you really are the Nerevarine, something so petty as a full inquisitorial process could hardly keep you from fulfilling your prophecies, now could it?
* In ''VideoGame/LeagueOfLegends'', Karthus the Deathsinger joined the Order of the Tallymen of Kindred (a collection of gravediggers, pyre-builders, corpse collectors and carers for the dying who follow [[TheGrimReaper Kindred, the incarnation of death]]) and rose to become quite prominent in the order. Once he decided he could learn no more about death from mortals, he traveled to [[IDontLikeTheSoundOfThatPlace the Shadow Isles]] and transformed himself into an immortal lich who trapped the souls of his victims in an undead state like himself, making him an abomination to Kindred, to whom unnatural prolonging of life beyond one's time is the greatest evil.
