No, he was put to death by the Romans with some encouragement by some of the Jewish hierarchy, and we generally know that this was done for mainly political reasons.
So, Jesus lied when he said he would guide his Church until the end of times?
The Church was and is the actual organization that Christ and the Apostles created, which both Acts and the epistles point out. It was not and is not some sort of loosey-goosey amalgamation of "just do your own thing". Jesus "taught with authority", as did the Apostles and as did and does the Church. It is the organization that selected your canon and evangelized throughout the known world. It is not perfect, but just a reminder that it wasn't perfect under Jesus either as the Gospels show.
No, the Romans didn't care about Jesus' spiritual teachings. It was the religious authorities of Judaism that constantly followed Jesus around, peppered him with questions and attempts to discredit him.
The Sanhedrin found him guilty of blasphemy.
John 18:28-40
28 Then the
Jewish leaders took Jesus from Caiaphas to the palace of the Roman governor. By now it was early morning, and to avoid ceremonial uncleanness they did not enter the palace, because they wanted to be able to eat the Passover. 29 So Pilate came out to them and asked, “What charges are you bringing against this man?”
The jews had to have the Romans put Jesus to death because they weren't allowed to.
Pilate said, “Take him yourselves and judge him by your own law.”
“But we have no right to execute anyone,” they objected. 32 This took place to fulfill what Jesus had said about the kind of death he was going to die.
Pilate then went back inside the palace, summoned Jesus and asked him, “Are you the king of the Jews?”
34 “Is that your own idea,” Jesus asked, “or did others talk to you about me?”
35 “Am I a Jew?” Pilate replied.
“Your own people and chief priests handed you over to me. What is it you have done?”
Pilate had no idea what Jesus had done so he wasn't even being noticed by the Romans for "political" activities!
Yes, Jesus has fostered the church as the best exponent of his life's work but he didn't interfere with how it evolved. Jesus established a spiritual kingdom not an authoritarian institution.
