Removed the Harry Potter example to here, since apart from being long and natter-filled it doesn't really seem to fit the trope - nothing like God or the Devil ever appear in the series.

• Harry Potter: Christian hymns are occasionally mentioned in regards to the celebration of Christmas and Easter is celebrated similarly. Word Of God says Harry had a Christening, so it seems that "godparent" does mean the same thing to wizards as it does to muggles. The biggest reference to religion would be the Bible verses on the Potters and Dumbledore family's graves, which spell out the biggest themes of the series. Otherwise, the subject of religion is never really brought up, though there is a "man in black robes" at a funeral and a wedding who seems to be a wizard clergyman.
  • Wizards probably don't have a specific religion: they just practice the same religion they would have if they were Muggles. It's obvious from the World Cup scenes that magic is not limited to one particular culture.
    • The question of why most wizards would accept the divinity of Christ when his best-known miracles(such as walking on water and conjuring loaves and fishes) would be doable tasks by at least the more competent members of their society.... goes unanswered.
      • Not at all. For one thing, it's stated in the seventh Harry Potter book that conjuring food by magic actually is impossible. (You can teleport it from somewhere else, but not create it completely anew.) Other miracles are probably better-known than those, namely raising the dead and rising from death himself, and both are beyond the Potterverse's magic. (Creating zombies is possible and ghosts are well-understood, but zombies are just animated corpses rather than the people they were in life and ghosts are spirits that chose not to go on to the afterlife and don't know what, if anything, awaits.) Mainly, though, most wizards we see in the series are British, and British culture is generally less credulous about the more fundamentalist aspects of religion than American culture, so British wizards may very well think of themselves as Christian without believing that Jesus literally rose from the dead.
      • Most Christians would probably argue that the miracles referenced above, while certainly "flashy", pale in comparison to, say, dying for the sins of all mankind, allowing each individual human the chance to repent and gain access to the eternal Kingdom of Heaven (just as an example). With little to no metaphysical framework established for Magic itself, there is nothing inconsistent about the existence Magic and the divinity of Jesus in the Potterverse (though the existence of Magic and the Laws of Physics...)
      • What if the "miracles" of creating fish and bread, as well as reanimation, are STILL miracles to the Wizarding World? Doesn't mean that one religion is correct; Just that, in that world, Jesus did something impossible.
