Not all X-ians believe that, but feeding your own kid to an idiotic religious mob so they can have him tortured to death by the government is really fucked up. I think their invisible, tyrannical, despotic sky wizard needs to go into family counseling either way.
You can tell it is fake because an omnipotent being required the torture of an unrelated party before it cleared a wholly fictitious debt. That's some mafia shit.
