Even now, people who claim they understand Jesus still don't get it.
Was Jesus Rich?
Some of these people claim that Jesus was rich because of the donkey. It all depends on what a carpenter made back then, doesn't it?
Some people claim He had nice clothes. I'm sure there was some way that people kept Him clothed, housed and fed, and maybe Jesus started off his ministry with a dowry to be "sufficient for his needs", but that doesn't mean He was wealthy.
As far as Roman guards auctioning off his clothes, it doesn't matter what "class" level His clothes were, that was done to mock Jesus, after Jesus drove the money changers out of the Temple.
Oh, and as far as having a treasurer in the organization, duh, how do you think the tithes were handled back then?
It doesn't make Jesus wealthy by the standards of the world, it means He was smart with his money and knew how the Church of Jesus Christ should be organized back then, even down to the position of Ward Clerk.
This "Prosperity Gospel" is nothing more than a distortion of the truth in order to make the wealthy feel less bad about their money. Of course, I don't hear them preaching about the sins associated with some of the ways some of these people GOT their money.
As for Jesus' real wealth, well, you'll have to go to the other side of the veil to see that. Here's a hint, since He created the earth with all of the gold on it, perhaps His wealth isn't a measure of money, but of power. He had the power to redeem us, and so far I have yet to see a mortal man create a physical earth.
