Jesus' clever dismissal of a legalist's kafka-trap. It worked because it created a new kafka-trap for the accuser to resolve. Quoting it like it means anything definitive is the height of ignorance and arrogance.

For detail of anyone who happens upon this: Jesus was being baited into rendering an opinion on a hot-button political issue, whether Jews should pay Roman taxes. This had no correct answer, as saying yes would weaken his appeal and make him look like a Roman shill, and saying no would be construed as an instantly arrestable offence for fomenting rebellion against Rome. His answer was brilliant because it asked the accuser to determine the most germane element of the question: If the currency is stamped with Caesar's bust, and you willingly use it as currency, then aren't you already a slave to Caesar? If you can rectify that in your mind, as naturally you would be able to, it's just currency, its not some spiritually significant thing, its just a means to an end, then haven't you already answered the real question being asked: does paying taxes stand in opposition to living a spiritually fulfilled existence? If it doesn't then your question is pointless, if it does, then you're already guilty and the question is pointless.
