Jesus threatened Caiaphas' relationship with Rome
Caiaphas' power base was the Sanhedrin, the supreme council of Jews which controlled civil and religious law. It had 71 members, mostly chief priests, and Caiaphas presided over its deliberations.
It was hard work but it had big rewards - modern archaeologists have discovered that Caiaphas and his associates lived lives of luxury with large and lavishly decorated houses.
But, of course, the Sanhedrin only ruled because the Romans allowed them to and the way to keep the Romans happy was to maintain order in society. Caiaphas himself was a Roman appointment, so he needed to keep cosy with the governor, Pilate, if he wanted to stay in power and preserve his luxurious way of life.
So if Jesus was making trouble, he was making trouble for both Caiaphas and Pilate - and trouble for Pilate was still trouble for Caiaphas.
Jesus was undoubtedly a threat; the public liked him, indeed they may have been paying more attention to Jesus than to the priests, and the public were listening to his condemnation of what he saw as wrong in the religious establishment.
Jesus threatened the Temple's income
Jesus was also threatening a useful source of income for the Temple priests.
The Temple apparatus brought in huge revenues for simple matters like purification and the forgiveness of sins. Archaeologists have discovered 150 mikvehs around the Temple. Mikvehs are ritual baths which Jews use in order to purify themselves before any act of worship.
Jewish people could only enter the Temple if they were ritually pure and almost everyone arriving in Jerusalem for Passover was deemed ritually unclean. They had to use a mikveh before they could fulfil their religious obligations. The priests controlled the mikvehs and charged people to use them.
There were so many regulations requiring ritual purification that control of the mikvehs was a way of making money.
Jesus thought the whole thing was rubbish. He taught that the elaborate purity rituals were unnecessary - the Kingdom of God was available to everyone and they didn't have to go through these rituals or pay the money in order to get there.
Bad news for the Temple apparatchiks. A quick way to raise a revolt was to tell people that they were being ripped off. This could cause a riot in the Temple if it got out of hand.
But there was worse. Jesus stormed into the Temple and accused the moneychangers and sacrificial dove sellers of extortion and of turning the Temple into a den of thieves.
The ultimate challenge to any religious leaders: What you are doing is against God and God will destroy you and cleanse the whole religious apparatus. And God, as every Jew knew, had the power to do it - he'd demonstrated that many times before.
Jesus was doing this in the Temple, in front of the crowds and without any fear or respect for Caiaphas and his staff.
Caiaphas had to do something to show that he was still boss, and he had to do it quickly; Jesus was on a roll, and who knew what he was going to do next.
