The Jews killed him before he could finish his mission. They demanded the Romans crucify him for blasphemy.
you mean that according to the gospels, Jews made a demand of their oppressors, and that demand was for a secular ruler to use a non-sanctioned form of capital punishment to kill someone who hadn't commited the crime of blasphemy uner Jewish law.
IOW, nothing that would make any sense in terms of Judaism
While Jewish religious leaders may have initially viewed Jesus' claims as blasphemy, the Romans were more concerned with political stability and potential threats to their rule. The Romans ultimately condemned Jesus for treason, not blasphemy.
Here's a more detailed explanation:
Jewish accusations:
Jewish religious leaders, particularly within the Sanhedrin, likely viewed Jesus' claims to be the Messiah, God's Son, and King of the Jews as blasphemy, violating Jewish religious laws.
Roman concerns:
The Romans, as the occupying power, were primarily concerned with maintaining order and preventing rebellions. They likely saw Jesus' claims and the growing number of his followers as a potential threat to their authority.
The charge of treason:
The Romans' legal system did not have a concept of "blasphemy." However, they did have laws against treason, which could include challenging the authority of the Emperor or inciting rebellion. Jesus' claims to be the King of the Jews were likely interpreted as a challenge to Roman authority and could be used to justify the charge of treason.
Pilate's decision:
While the Jewish leaders may have requested Jesus' execution for religious offenses, Pontius Pilate, the Roman governor, ultimately decided on the charge of treason. He likely felt the risk of Jesus' followers potentially destabilizing the region outweighed any religious considerations.
But it was the Jews that demanded Jesus be crucified.
Mark 15:13-15 NIV - “Crucify him!” they shouted.
13 “Crucify him!” they shouted. 14 “Why? What crime has he committed?” asked Pilate. But they shouted all the louder, “Crucify him!”.
