God Test

"So you are the Christ, yes the great Jesus Christ!
Prove to me that you're divine; change my water into wine!"
Jesus Christ Superstar, "Herod's Song"

Extraordinary claims require extraordinary evidence. Therefore, when an ordinary-looking character claims to be God, Satan, a wizard, time traveller, robot, or alien, skeptics nearby will often demand a God Test to prove those claims. This will typically be a fantastic feat of some sort, something to be done that a regular person would never be able to do. The challenged party succeeding at the test is fairly rare, but they may respond with an explanation as to why they won't or why the test isn't meaningful. Thanks to Jesus' classic example there's a fair chance in the story this means they're on the level. Coming up with a test and having the God fail it is a good way to expose an impostor.

Often expressed as "If you're <X>, then do <Y>!"

Note that, despite the name, the test is not limited to deities; any character claiming extraordinary abilities can be challenged with such a test.

  • During Peter David's run on Supergirl, with the "angel" version of the character, she meets a little boy who claims to be God, come to speak to her. She asks for proof, and He asks what sort of miracle would prove anything in an age of superheroes who can fly, transmute elements, etc.; so she's just going to have to take it on faith.
  • During the "Heroes Return" story arc in Marvel Comics, most of Marvel's heroes have had their memories of their "real" lives erased and they lived in a pocket universe for a year. They are confronted by a Celestial who demands that they return to a home they don't remember. If they don't, either the pocket universe will be destroyed, or the regular Earth will. Thor objects, saying that he thinks all of them together could take her. In response, she snaps her fingers and turns Thor, a god in his own right, into a frog. He retracts his objection.

  • In Oh, God!, Jerry Landers asks the old man claiming to be God to prove it by making it rain. On cue, it suddenly starts to rain... inside Jerry's moving car.

He concludes his visit by vanishing in full view of the audience, and there are no recordings (audio or written) of His testimony.
  • Played with in Bruce Almighty, when Bruce tries to catch God (the other one) with a How Many Fingers? test. After God guesses correctly every single time, Bruce tries to fake him out by holding up five fingers on one hand and two on another, then very quickly putting two fingers away when God says "Seven." When Bruce triumphantly holds up his one hand, it suddenly has that many fingers. Apparently, God also pulled the same stunt on Gandhi, who took it a lot harder than Bruce.
  • M. Night Shyamalan's The Last Airbender has one of these.
    "The Avatar would be an Airbender. Can you Airbend, boy?"
    • The test goes on to show the elements reacting to Aang's presence- i.e. rocks move towards him, water falls into a perfect circle, etc. The scene is infamous for making very little sense, because it doesn't explain why the elements don't do it all the time, suggesting that Aang did it on purpose, allowing himself to be captured.
  • In Back to the Future Part II, young Biff challenges his future self to prove that the Sports Almanac knows the results of every sporting event in the next 50 years. So old Biff turns the radio to a college football game which ends exactly as the Almanac says.

    [quadruple air guitar]
    • Double subverted in the sequel; when the heroes' Evil Twins arrive, Ted is suspicious, but Bill convinces him to trust them. Then Ted trusts his robot counterpart after it passes a How Many Fingers? test.
  • In The Man from Earth, John Oldman quietly foils his friends' attempts to prove him wrong by explaining that most of his knowledge WOULD fit in with textbooks because that's what happened. Then he starts explaining that he was both a student of the Buddha and the resulting inspiration for the biblical Christ, to everyone's dismay, but he still cannot (or at least will not) give them true proof of his immortality. At the end, he unwittingly exposes himself to be the father of his psychologist friend, (said friend looks to be twice John's age) giving the man a heart attack and proving, in the viewer's eyes, that his story was true.
  • Angel-A eventually proves her claims to André.

  • In Hook, Smee and Hook confirm Peter's identity as Pan, but see that he seems to have changed quite a bit. They tell him they'll give his kids back if he merely flies a little. (Upon failure of such, and at Tinkerbell's urging, they extend the challenge by giving him both more tasks and more time.)
  • In Ghostbusters, Gozer performs a god test on Ray by... asking him if he's a god. Ray fails by simply telling the truth. (Of course, there's no knowing whether Gozer would have demanded more proof had Ray answered yes.)
  • Inverted and utterly subverted in Monty Pythons Life Of Brian, where no evidence can disprove Brian's divinity:
    Brian: I'm not the Messiah! Will you please listen, I am not the Messiah! Do you understand? Honestly!
    Female follower: Only the true Messiah denies his divinity.
    Brian: What!? Well, what sort of chance does that give me? All right, I am the Messiah!
    Crowd: He is! He is the Messiah!
  • The Day the Earth Stood Still (1951). As a demonstration that he is a powerful alien, Klaatu is asked to stop traffic so a man can cross the street.

  • In Bernard and the Genie, the Genie tries to kill Bernard as soon as he's summoned. Bernard stops him by wishing he'd stop trying to kill him, but still doesn't believe he's a genie.

  • In The Last Hero the Silver Horde try to sneak into Dunmanifestin by claiming to be 'new gods'. The locals know what's going on but, being who they are, decide to have some fun by demanding Cohen prove his bonafides by rolling a seven on a six-sided die. He does.
  • During the Horus Heresy series, the Emperor repeatedly and vehemently denies any godhood. This trope gets inverted, however, because half the stuff he does SEEMS like it should take a god to accomplish, so no matter how much he denies it, the "true believers" just say "only a true god would deny his divinity while also demonstrating it."
  • In Will of Heaven, the Guest of Canghai asks Han Xin what he has to do to make the latter believe he serves a real god. Han Xin offhandedly tells him to make a river disappear. He does.

    Lister: "I'm serious."
    Cat: "So am I!"
  • For a show that dealt with fake gods, Stargate SG-1 only ever used this test once, and indirectly at that. When Gerak becomes a Prior of the Ori and is asked to destroy Jaffa who refuse to believe, Teal'c asks him what makes him believe they are gods, citing various impressive miracles they could have performed.note  He then posits that the measure of a god is not how they display their power, but how they apply it. If they were gods, they wouldn't need Gerak to kill anyone on their behalf, or even ask such a thing of him.
  • The Bionic Woman: Jaime Sommers has been replaced by her evil twin, and dropped into prison in her place.

Hurley is afraid of inadvertently being God Tested and revealed to be a time traveler when he's unable to answer a question that someone living in 1977 should be able to. He's right to be afraid of this, given that his example of such a question is "who's President in 1977?" Pierre Chang eventually gets suspicious and trips him up easily.
    Pierre Chang: What year were you born?
    Hurley: 1930.
    Pierre Chang: So you're 47 years old?
    Hurley: Yes.
    Pierre Chang: And you fought in the Korean war?
    Hurley: Ha! No such thing!

    Mythology and Religion 
  • The Bible features many examples and some of them very old. In general, the Old Testament is much more okay with God Tests than the New Testament. Old Testament God was very active, with his miracles ranging from the subtle, such as ensuring Isrealite victory in battle, to the obviously supernatural, such as raining down fire. In the New Testament, God was much more subtle, his only direct miracles being the impregnation of Mary and the resurrection. Jesus was generally willing to perform miracles, but he often asked that word of his miracles not be spread around, particularly his miraculous healings, and only engaged in one 'large scale' ritual, the feeding of crowds with only a few loaves of bread and fish.
    • God provided Moses with some evidence of Who sent him, starting with giving Moses temporary leprosy and turning his staff into a snake and back (with enough time for it to eat the Egyptian priests' staff-snakes), followed up by the Ten Plagues.
    • Gideon has a inversion; He was unsure that he (Gideon) was really The Chosen One and wanted to make sure before he went off starting a war. He leaves a fleece on the floor overnight; once, having the fleece be wet with dew while the floor is dry, and once vice versa. Both are performed without objection.
    • Satan tries to invoke this by suggesting Jesus prove he was the son of God by turning stones into bread. Jesus refused, saying "It is written; Man does not live on bread alone, but on every word that comes from Godʼs mouth." Not to be put off, Satan told him to jump from the roof of the temple, saying "If thou be the Son of God, cast thyself down from hence: For it is written, He shall give his angels charge over thee, to keep thee: And in their hands they shall bear thee up, lest at any time thou dash thy foot against a stone." Jesus refuses again, saying "Again it is written, 'You shall not put the Lord, your God, to the test.'"
    • Also invoked in the New Testament letters. The Apostles instruct Christians to test any spirit claiming to be from Heaven, by verifying that the spirit in question confesses Jesus is Lord and that He came in the flesh, because demons will masquerade as angels of light to try to deceive people, but will never confess Jesus's Lordship or Incarnation before mortals, because doing so would defeat the point of the deception.
    • King Herod (Antipas) tested Jesus on the day of His crucifixion to see if He would do all the miraculous things he had heard about. Jesus did nothing.
    • When Jesus is on the cross the authorities challenge him, "If you are the Son of God, come down from the cross."
    • Played straight by Jesus and Thomas. When Thomas hears of the resurrection, he refuses to believe the story, thinking it incredible. It is not until Jesus shows Thomas his crucifixion wounds that Thomas believes. Jesus then says that it would have been better for Thomas to have believed without seeing his wounds.
  • According to the Koran, Mohammed refused to perform any God Tests to prove that he's a prophet, since there are several such stories in The Bible and in every one of them the prophets passed the tests but the crowds still didn't believe them. Since it never works, God wouldn't perform any more miracles only for the entertainment of disbelivers.
  • As the tales where this trope does pop up can tell you, it's generally very dangerous to ask The Fair Folk to prove themselves to you. Partially because, if they are of the kind that Cannot Tell a Lie, they are likely to get insulted by the fact that their word is not good enough for you; cue Disproportionate Retribution, and partially because, well, they are The Fair Folk: If the only thing you wish for is to know if they really are the beings they claim to be, don't blame them if the knowledge that they really were the beings they claimed to be is the only thing you're left with.

    Newspaper Comics

     Tabletop Games 
  • One of the black cards in Cards Against Humanity instructs the players to use one of the white cards in their hand to answer the question, "What will I bring back in time to convince people that I'm a powerful wizard?" Answers can range from the absurd ("George Clooney's musk") to the mundane but probably seemingly-magical to people from the past ("that thing that electrocutes your abs") to the actually-supernatural ("being a motherfuckin' sorcerer").

  • Jesus Christ Superstar. Quoth Herod to Jesus, "Prove to me that you're no fool/Walk upon my swimming pool." Of course, Jesus in the Gospels also comes up against demands for miracles to prove his status, and refuses to play along with them.
  • In Aristophanes' The Frogs, The god Dionysos and his servant both claim to be the real Dionysos, and the gatekeeper of Hades decides to tell them apart by flogging them. Supposedly, a real deity can't feel and won't react to pain. This being a parody, they both fail.

  • The Neverwinter Nights 2 fan module The Maimed God's Saga has a cleric of Tyr as the Player Character. At one point a mob assembles in the town square demanding that you prove you're really a cleric. You can blow them off without consequence, or if you have the spell remove disease prepared, you can cure a sick woman in the crowd.
  • In Futurama: The Game, Leela ends up encountering the Sun God, who was lauding his powers over the local underdeveloped civilization living on the Sun. Leela asks that he prove that he is a God, but this angers him and causes a boss fight. After defeating him, he admits the truth.
    "You found me out... I'm not really a god... I'm *cough* *cough* just an ordinary... eternal, omniscient, superintelligent being."

For him, it's rather easy; just do a little Airbending, as the Avatar is the Last Airbender.
