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 actually 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 , then do !"

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

Comic Books

 * 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.

Films -- Animated

 * In The Road to El Dorado, the Doradans challenge the explorers to a ballgame... two gods against 15 mortals.

Films -- Live-Action
""The Avatar would be an Airbender. Can you Airbend, boy?""
 * 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.
 * Later, God proves His divinity in a courtroom by making a deck of cards appear and disappear in plain view. He concludes his visit by vanishing in full view of the audience, and there are no recordings (audio and written) of His testimony.
 * Played with in Bruce Almighty, when Bruce tries to catch God (the other one) with a How Many Fingers? God Test. After God guesses correctly a few times, Bruce manages to fake him out by 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.

"Ted: "If you guys are really us, what number are we thinking of?" Future Bill and Ted: "69, dudes!" Bill and Ted: "Whoa..." [quadruple air guitar]"
 * In Back to The Future Part II, Biff challenges his future self to prove that the Sports Almanac knows the results of every sporting event in the next 50 years.
 * Bill and Teds Excellent Adventure: Invoked when Bill and Ted challenge their future selves:


 * 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.
 * Star Trek V: "What would God need...with a starship?"
 * In The Man From Earth, John Oldman quietly subverts 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, to everyone's dismay, but he still cannot (or at least will not) give them true proof of his immortality. At the end,.
 * Angel-A eventually proves her claims to André.
 * Just Like Heaven has David convincing Jack that Elizabeth's right behind him. Jack pulls a How Many Fingers? that concludes with him Flipping the Bird. And despite this, it still takes a Something Only They Would Say moment to convince him

Literature

 * A Connecticut Yankee in King Arthur's Court plays with this one memorably: a charlatan claims to be able to tell people whatever is happening anywhere in the world. After listening to various plausible tales of the doings of foreign potentates, the main character takes his turn: "Tell me what I'm doing with my hands behind my back right now."
 * 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."
 * The Bible features one of the oldest examples in existence, and probably the oldest subversion; 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' Lordship or Incarnation before mortals, because doing so would subvert the deception.
 * When Jesus is on the cross the authorities challenge him, "If you are the Son of God, come down from the cross."
 * On the other hand, going even farther back, God did provide 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.
 * Also in the Old Testament, Gideon tests God twice, both times by leaving 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.
 * 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 crucifixtion wounds that Thomas believes. Partially subverted as Jesus then says that it would have been better for Thomas to have believed without seeing his wounds.
 * 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. In addition to the above mentioned examples, there appears to be a large shift in Gods feelings about the idea of God Tests between the Old and New Testaments.

 * Inverted in the Star Trek: The Next Generation episode "Who Watches the Watchers." A primitive alien tribe has come to believe that Picard is God (despite his protests), and to prove it one of them shoots him with a bow to prove that The Picard can't be killed.

 * 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 . 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.

Real Life

 * As with many Native American peoples, the Tainos of Puerto Rico were told that the Spaniards invading their land were gods. To make sure, they caught one and tried to drown him... and succeeded. Even then they had no chance against the invaders however.
 * As shown above, Carl Sagan's famous quote, "Extraordinarily claims require extraordinary evidence," is an excellent summary of skeptics' treatment of claims of this magnitude.
 * 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.
