Why did the jews reject Jesus teachings when he was one of them and they saw his mriacles?

At the time of the 1st century in Palestine, there were many self-styled leaders who arose claiming to be the Messiah. To many traditional Jews, Rabbi Jesus/Yeshua was just one of several who either made the claim or their followers made the claim in their stead. Rabbi Jesus/Yeshua also introduced some ideas into his teaching which were not especially Jewish.

Some of that came as a result of his sect. The sect was lead by John the Baptist/Yohannan the Baptizer until his death at the hands of some of the authorities, which pushed the Good Rabbi into early leadership of the sect that some scholars claim was a branch of Essenic Judaism. Interestingly, some of his ideas would get traction within the later Jewish traditions in Kabbalah, but not about the man himself.

Some have speculated that the ideas of Jesus/Yeshua may have had origins in Eastern traditions and that he reconfigured the teachings for a largely Jewish audience. Looking at the Nag Hammadi writings, especially the Gospel of Thomas, Jesus/Yeshua is almost Mahayanna-like in his teachings. This drift from orthodoxy really irritated some of the Jewish leadership.

Paul of Tarsus is said to have taking the drift away from Judaism even farther.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
