Paul of Tarsus
The apostle responsible for spreading Christianity among the Jews was Paul.
Christians did not learn about Christianity from the Jews. Christianity was founded, as a religion, by former Jews. However, by the time they were proselytizing their new faith, it was distinct from Judaism and Jewish doctrine.
The origin is at Christ's resurrection, if this did not happen Christianity has no value. Paul clearly states this in one of his letters.The first wave of spreading followed Pentecost, when Jews returning to their distant homes in other lands told of hearing uneducated Galilean Jews preaching a new Messianic message in tongues they could not know themselves but were the native tongues of the visiting Jews.The second wave of spreading was brought about by Paul's missions to the Gentiles.
The first Christians were Jews.
Although the Christian Old Testament was based on the Tanach (Jewish Bible), the Christian OT was altered to support the teachings of Christianity and therefore is not accepted by Jews, Zionist or not.
they didn't choose christinaity. Christianity chose them. they're the chosen people. God chose the Jews to be his first people.
In Judaism, no Jews believe this.
about what, christianity?
The question should be " What does Christianity have to do with Jews (or Judaism)?" Judaism is like a tree where Christianity is its branch and Islam is it leaves. Christianity is based on Judaism and Islam is based on Christianity. The major difference between the three is that Judaism doesn't have jesus in it unlike Christianity and Islam.
Arthur B. Klyber has written: 'He's a Jew' -- subject(s): Christianity, Christianity and other religions, Judaism, Relations 'Jews and you /[ Arthur B. Klyber' -- subject(s): Christianity, Christianity and other religions, Judaism, Relations 'Once a Jew' -- subject(s): Conversion to Christianity, Jews 'Queen of the Jews'
It is called the diaspora (dispersal).
I believe that this would be Paul. Because of his insistance in preaching the gospel, and even though he was a Roman citizen he was put to death.
