Jesus the man knew his execution was a predictable outcome. He was knowledgeable about human behaviour and he understood that martyrs are long remembered and their deaths often ensure their cause and their message outlive the martyr. He saw his death as a sacrifice that was essential to strengthen the movement and to ensure it would continue beyond his lifetime. I suspect that even Jesus could not have anticipated how much his sacrificial act contributed to a religious movement that has persisted in a wide variety of forms for over 2,000 years.
Of course, his followers were smart to purge all the Jews who part of the Jesus movement in the early days. Those people were still strongly tied to Jewish law and the Torah and would not, in the long run, be good Christians. The roman citizens and former pagans in the movement were better suited to keep the fledgling religion going and they expanded the belief system to include mysteries and miracles that gave the new religion the trappings that make it easier to spread the faith throughout the world.
The periodic exploitation and slaughter of Jews and Muslims over the centuries helped consolidate the gains of spreading the faith and to line the pockets of European nobles who raised armies for the crusades to purge the Holy Land of those who did not accept the Christian faith. The Inquisition enriched the Church by seizing the property of Jews and Muslims who did not agree to being forcibly converted. It laid the groundwork for long-standing antisemitism.
Even in the 7th Century, Pope Clement actively persecuted Jews and continued to blame Jews for the crucifixion of Jesus, even though the Roman Empire was run by Romans and not the persecuted Jews living under the heavy hand of the Roman rulers.
In fact up until Vatican II, the Church continued to hold the Jews responsible for the crucifixion. These notions were not discarded after the Protestant Reformation.
Even into the 20th these ideas continued to be repeated from the pulpits of many churches of most denominations at Easter services.
I believe Jesus was a man, a teacher and perhaps a prophet who may or may not have believed he was the Messiah. His followers certainly asserted that Jesus was the Messiah despite the fact that most of the ancient prophesies about what would happen when the Messiah come were not fulfilled. This lead to the promise of a second coming which would be the time when those prophesies would then be fulfilled.
While I am not a Christian, I believe that many Christians today have abandoned old prejudices against Jews. Of course there has been a significant rise in hatred and prejudice against Muslims as a result of 9/11 and the subsequent attacks on Iraq and the ongoing war due to the attempt to continue to occupy Iraq by the USA.
I am opposed to racial and religious hatred and persecution. Do you suppose Jesus felt the same way?
