I still have difficulty understanding how any Christian theology and doctrine could come up with the idea of blaming anybody for the death of Jesus, and build up a case century after century against "the Jews" for killing the messiah
I understand, but as Christians we take our understanding of things Biblical from the NT, where we find
Jesus declaring the
Jewish religious leaders guilty when he declared them not children of God nor of Abraham, but children of the devil because
they sought to kill him (
John 8:38-47). He also declared them guilty and condemned them to hell when he declared
that the blood of all the righteous from Abel to Zachariah was on their heads (
Matthew 23:29-36), because in seeking
to murder him, "the
prophet who was to come" (
John 1:45;
John 6:14), promised by Moses (
Deuteronomy 18:17-19),
and subsequently to murder his apostles
(
Matthew 23:33-34), they were endorsing all such murders committed by their forefathers (
Matthew 23:30-32) and
would suffer the penalty for those murders.
So it is Jesus that held the religious leaders of his day
guilty of (Pilate was
responsible for) his death.
So it is not surprising that the
apostles likewise taught that the Jewish religious leaders of his day were guilty of the murder
of Jesus (Acts 5:28, Acts 7:51-52, Acts 3:12-15;
1 Thessalonians 2:15).
Acts 7:51-53 - (Apostle Stephen speaking before the High Priest in the Sanhedrin to answer charges against him
of "speaking words of blasphemy against Moses and God")
"You stiff-necked people, with uncircumcised hearts and ears! You are just like your fathers; you always resist the
Holy Spirit! Was there ever a
prophet your fathers did not persecute? They even killed those who predicted the coming of the
Righteous One. And
now you have betrayed and murdered him--"
Acts 3:13-15 - (Apostle Peter speaking to the Jews after he healed the crippled beggar at the temple gate)
"The God of Abraham, Isaac and Joacob, the God of our fathers, has glorified his servant Jesus.
You handed him over
to be killed, and you disowned him before Pilate, though he had decided to let him go. . .
You killed the Author of Life,
but God raised him from the dead."
Acts 5:28 - (The High Priest addressing the apostles who had been released from prison by an angel)
'You have filled Jerusalem with your teaching and are
determined to make us guilty of this man's blood."
THe NT does not hold all Jews responsible for the murder of Jesus, only those who reject him.
And Christians take their view of things Biblical from the NT.
The
Biblical principle involved is: Everyone is
responsible for his own actions.
And God uses lemons to make lemonade.
