quoted from: "Christs' Assault on Blood Sacrifice"
Several hundred years after prophets like Isaiah, Jeremiah, Amos, and Hosea had denounced the sacrificial slaughter of animals, Jesus carried out what is euphemistically called the Cleansing of the Temple.
It was just before Passover and he disrupted the buying and selling of animals that were being purchased for slaughter.
And because Christian scholars and religious leaders continue to ignore biblical denunciations of that bloody worship, they also try to obscure the reason for Christ's assault on the system.
They have done this by focusing on the moneychangers, although they were only minor players in the drama that took place.
It was the cult of sacrifice that Jesus tried to dismantle, not the system of monetary exchange.
In all three gospel accounts of the event, those who provided the animals for sacrifice are mentioned first: they were the primary focus of Christ's outrage.
[Jeremiah] had hurled the same accusation at the people of his own time, almost six hundred years earlier. He said it while standing at the Temple entrance, after he had already warned the people "do not shed innocent blood in this place."
And when Jeremiah said God's house had been turned into a den of robbers it could not have had anything to do with moneychangers--they did not exist in his time.
Both Jesus and Jeremiah were indignant about the violence of sacrificial worship, not the possibility of petty theft by moneychangers.
It was the violence of the system, the killing of innocent victims in the name of God, that they were condemning.
The moneychangers operating in the time of Jesus were driven out of the Temple because they were taking part in the process of sacrificial religion, not because they may have been cheating the pilgrims.
It is ridiculous to claim that the religious leaders of Christ's time would have plotted his death because he undermined the function of the moneychangers.
Nor would the crowd have been "amazed at his teachings" if Jesus was simply telling them to make sure they were not short-changed when they purchased Temple coins.
What the people were amazed at was his condemnation of animal sacrifice; it had been hundreds of years since that kind of condemnation had been heard in Jerusalem. And it would not be allowed.
