In Acts 5, we are told that there was a wise man in the council at Jerusalem, 'a Pharisee named Gamaliel, a doctor of the law'. He was not a Christian, but when the followers of Jesus appeared on the scene he said, 'And now l say unto you [Jews], Refrain from these men, and let them alone: for if this counsel or this work be of men, it will come to nought: But if it be of God, ye cannot overthrow it; lest haply ye be found even to fight against God.'
Based on Gamaliel's assessment of the movement and the claims, it seems that he was right. The spread of the Gospel did continue, and was accompanied by many signs and wonders. Now, it seems, some people are beginning to realise that to deny Christ is to deny God.
This tale wasn't written till c. 90 CE, sixty years / two or three generations after the traditional date of the crucifixion, so whether it was historical or just a story, it had all that time to be polished. And if it's roughly accurate, so what? That doesn't make Jesus a Jewish messiah.
And anti-semitism? Is that not also explained in the scriptures, or have you overlooked the words of Moses?
Deuteronomy 28:1. 'And it shall come to pass if thou shalt hearken diligently unto the voice of the LORD thy God, to observe and to do all his commandments which l command thee this day, that the LORD thy God will set thee on high above all nations of the earth:'
There we have the promise of blessing upon the obedient. But what of disobedience?
Deut. 28:15. ' But it shall come to pass, if thou wilt not hearken unto the voice of the LORD thy God, to observe to do all his commandments and his statutes which l command you this day; that all these curses shall come upon thee, and overtake thee:' [There follows a long list of curses]
Deut.28:25. 'The LORD shall cause thee to be smitten before thine enemies: thou shalt go out one way against them, and flee seven ways before them: and shalt be removed into all the kingdoms of the earth.'
So the Jewish messiah, you say, is himself the cause of the greatest and most sustained and most murderous and rapacious antisemitism?
Christian antisemitism is fine with you because of something Moses (if indeed there was an historical Moses at all) is said to have said? Christianity exists to persecute and murder Jewish people?
God sent the Jewish people a messiah [he] knew they wouldn't recognize, set them a test [he] knew they must fail, you say?
And as a result the Jews have deserved the Christian pogroms, ghettos, gas chambers, for not recognizing your hero as their "king", in your view? Hitler nailed it, you think?
I think that's an inhuman view, to be rejected instantly and outright.
And by the way, the Jews never turned from their God.
Why, for example, would the Jews, having worshiped their God directly in prayer for more than a millennium, suddenly need an intermediary? That's an idea from gnosticism, but only Paul and the author of John were gnostics in the NT.
It was and is the Christians who rejected the Jewish God and indeed in the fourth century CE invented the "Triune God" in order to elevate Jesus to God status, despite every version of Jesus in the NT denying he's God, and never once claiming to be God. If, as you say, Jesus was God all along, then his ministry was one long deceit, a lie fully lived. And Jesus prayed to himself in the garden, and the Jesuses of Mark and of Matthew said on the cross, "Me, me, why have I forsaken me?"
Sheesh.
As for "the stem of Jesse", nope, the Jewish priesthood, the leaders of the Jews, will tell you who's a Jewish messiah and who's not a messiah.
