You're looking at it backwards.
You need to go back to the Bronze Age, when Aryans spread out in all directions, and took their religion with them. All of the religions have a common origin, so there were Zeus type gods from India to Portugal, and from Finland to Egypt.

jews didn't exist in the Bronze Age. The earliest historical reference outside of the Bible to Yehud is as the provincial name given to the region of Jerusalem by the Persians. In the Bible, Judah is the bad son, who sells his little brother into slavery. Judas is the betrayer of Jesus. The glorification of jews is from jews, not Christianity. And all the records of the Early Church show great animosity towards jews. The jew love by Christians is new, mostly beginning with Scofield in America, a bit with the Plymouth Brethren in England. But their main power in Europe was not religious, it was monetary. It was our kings that sold us out, not the church.
