And your source for this is, what exactly? The gospels and epistles of the Christian scriptures? I expect you'll disagree, but I don't think we can count on them to give a fair and accurate depiction of Judaism and Jewish reaction to the early Christian movement. These are polemical works, advancing their own particular viewpoints. They are not objective histories.
It is written in the Holy Scriptures:
Jesus said:
Verily, verily, I say unto thee, Except a man be born again, he cannot see the kingdom of God.
The Gospel of John, Ch. 3 vs. 3
How about Flavius Josephus?
