@Olivier5,
Nice post, O5. One of the reasons I remain so convinced Jesus did exist is because of the enduring hatred Jews have had to weather for centuries simply because of this individual.
Also, since the world had very few people it's not likely Jesus' impact would have been outside his main area. Jesus' ideology, however, did live on even though for a while Christianity almost died out and Jesus himself almost forgotten.
"Jesus doctrine created the first Christians, as described in the first chapters of the Acts of the Apostles; they were all Jewish, either by birth, or conversion for which the biblical term proselyte is used,[1] and referred to by historians as the Jewish Christians. The early Gospel message was spread orally; probably in Aramaic (the language of Jesus).[2] The New Testament's Book of Acts and Epistle to the Galatians record that the first Christian community was centered in Jerusalem and its leaders included Peter, James, and John.[3] Paul of Tarsus, after his conversion to Christianity, claimed the title of "Apostle to the Gentiles".
