-- Jn 11:45-56
The religious authorities in Jerusalem were not unanimous about what stance to take towards Jesus. The Pharisees threatened to excommunicate his followers. To those who feared that "everyone will believe in him, and the Romans will come and destroy both our holy place and our nation", the high priest Caiaphas replied by prophesying: "It is expedient for you that one man should die for the people, and that the whole nation should not perish." The Sanhedrin, having declared Jesus deserving of death as a blasphemer but having lost the right to put anyone to death, hands him over to the Romans, accusing him of political revolt, a charge that puts him in the same category as Barabbas who had been accused of sedition. The chief priests also threatened Pilate politically so that he would condemn Jesus to death.
