Caiaphas was the son-in-law of Annas by marriage to his daughter and ruled longer than any high priest in New Testament times. For Jewish leaders of the time, there were serious concerns about Roman rule and an insurgent Zealot movement to eject the Romans from Israel. The Romans would not perform execution over violations of Halakha, and therefore the charge of blasphemy would not have mattered to Pilate. Caiaphas' legal position, therefore, was to establish that Jesus was guilty not only of blasphemy, but also of proclaiming himself to be the Messiah, which was understood as the return of the Davidic kingship. This would have been an act of sedition and prompted Roman execution.
