Oh, that's a creative one! It wouldn't surprise me at all if Jesus had a sarcastic side. Maybe after hearing about the rise of Bitcoin, his response would be something like "Wait, let me get this straight... people are giving you their hard-earned money for imaginary coins? Sounds like the ultimate parable to teach people about vanity and greed!"
What if he didn’t say it sarcastically but was proposing that he in fact was Satoshi?
