I'm not necessarily stating my beliefs, just reporting the claims of this book and also in some cases extending to logical conclusions the authors' theories and suggestions as I felt them to be. I hope I neither offend anyone, nor misrepresent what Crossan was attempting to say.
Jesus was of rural, small-town origins.
Jesus was born into one of the most desolate areas of his homeland. Galilee of that era was the sticks and Nazareth was not a community so much as a commune. It was around twenty buildings housing circa a dozen families, their livestock, their possessions. There was no road leading to it, merely a footpath many miles through the wilderness. There was a communal well, but no public buildings such as a house of worship, law court or marketplace. The people of Galilee spoke in a "rural" accent so thick it was all-but incomprehensible to the more urbane Jews of Jerusalem. Jesus was from such an off-the-beaten-path place it is unlikely many living more than a few miles from it had even heard of Nazareth. In other words, we're talking remote.
Jesus was possibly an illiterate.
Before this sounds impossible, remember, even in a Jewish population that prized education among males, most people at that time and place were probably illiterates. This is not to say Jesus was unintelligent. The quotes and parables attributed to him suggest he was anything but mentally deficient. Jesus would have had a strong background in the oral traditions of his people and like most illiterates, the parts of his brain that dealt with memorization would have been highly stimulated, giving him a keen memory and immediate grasp of verbally-presented facts.
Jesus' parentage.
Jesus may have been conceived without sex and born to a virgin. The realm of religion makes amazing claims that cannot be proven or disproven. That being the case, I will say little on this claim except it bears much more resemblance to the Hellenistic purity cults' tales of virgin birth, a thing all-but unknown among the Jewish religious history. Sociologically speaking, I was surprised to learn in this book that it was a tradition among Jews of that era for an engaged couple to conduct sexual relations without dishonor, and a marriage took place only when the man was able to provide lodging for his wife. However, some Jews at this time had begun to rebel against this unscriptural conduct. These eschewed sex until the actual marriage, as pious Jews are supposed to today. The more rural Jews were especially known for this throwback to earlier piety, and since Jesus was of rural heritage, it seems likely the story in the Gospels of Joseph wanting to "quietly" break his engagement to Mary when she was found to be pregnant shows how Joseph was more concerned with making it clear he had not slept with her before marriage than with the fact his fiancée was pregnant with another man's child. In other words, he was a conservative person who would have been likely to give Jesus and his brothers a conservative upbringing.
Jesus was depressed during much of the record we have of his life.
Jesus would have sudden, violent swings of mood and he would alter his philosophical positions at the drop of a hat. He seemed to want to be friends with everyone from the Romans (healing the Centurion's servant; his remark render unto Caesar what is Caesar's) to the Temple priests (forestalling violence against the Temple) to the impoverished (the poor shall inherit Heaven), to the elite (there will be poor always).
Jesus never wanted to found a new religion.
It seems Jesus wanted a movement within Judaism (which was boiling with sectarianism and change at that time) not a separate faith. Jesus from circa 30 AD was not the Christ of modern Sunday schools, he was a flesh and blood man who was courageous enough to try to fit together the mysteries of life and God and act on what he thought of as right. To me this is more admirable, approachable and embraceable than the miracle-working deity myth has made of him. Jesus of Nazareth may not have always felt he was the Messiah. The written record shows him vacillating on whether he even was the Promised One. At no point does Jesus ever in the Bible call himself a Christian, tell anyone to stop being Jewish or conduct himself as other than a Jew, albeit a Jew with radical notions.
Jesus died.
But Jesus almost made it. Yep, he seemed to go looking for death that Passover and he found it almost in spite of himself. Had he stayed out of Jerusalem altogether or even out of it at that tumultuous time he would have been no threat to anyone with the authority to put him to death. The Romans cared little what their subject people believed as long as they kept the taxes coming in and made no trouble for them. Since Jesus seemed to focus scant energies on opposing Roman rule, it is unlikely without instigation from the high priests whom he threatened directly, the Romans would ever have flicked a muscle to dispatch this backwoods charismatic. In fact, I have always thought Jesus would have been hosted as a philosophical radical and deep thinker and given respect had he settled among Rome's thriving, quiet Jewish community instead of in what was Rome's most annoyingly problem-ridden province. Jesus was most likely arrested by the Romans as a favor to the Jewish leadership, who were collaborators to Roman authority. The Romans frankly didn't want Jesus. They did not speak his language, they did not recognize his God. His claims to prophecy and miracles meant nothing to them. They regarded him as so insignificant that though his disciples were all in place and well-known, they were not arrested in Jerusalem alongside their master. The Romans tried to turn Jesus over to the Jewish "king" Herod to deal with, but Herod knew the possible consequences of punishing the leader of a volatile rabble, so this pleasure-loving man (rather like a fourth generation trust fund kid who lives off ancestral money in Palm Beach) turned the country preacher back over to the Romans, who made every attempt to avoid responsibility in this matter until the passionate fervor of Passover died down, but the Temple priests and religious aristocrats would not allow this, so Jesus was executed as a common criminal, in a very painful manner: a death he may have partly wanted but which he obviously did not deserve.
Jesus in the grave.
Jesus was buried in the manner usual to his time, place, and economic standing. His body was anointed with oils and herbs and placed in a woven shroud. He was set into a hillside niche and a stone was rolled before the opening. In a year or thereabouts, once the flesh had gone from the bones, family or friends (or professional undertakers) would have come and collected the remains for burial under the earth. The story of Jesus returning to life after three days in the tomb is, like his conception, an article of faith, unproven, unprovable. Did Jesus reappear from the grave? Premature entombments are not a thing of fiction but of fact. A cave sealed by a stone would have been infinitely more accessible to egress than a modern earthen grave. In fact, the Gospels tell us that Jesus seemed to die suddenly (or did he lose consciousness?) and that weather conditions were not the best. So is it possible Jesus was taken from the cross by Roman grunts who didn't want to be out in a storm and not given the most comprehensive autopsy in history? There was even a case cited in "Excavating Jesus" of a Jew who survived a death sentence on the cross, recovered and lived many years thereafter. In this claim we irreversibly leave behind the man Jesus and come to the deity Christ. We depart from facts and history and enter myth, faith, dogma and past this, no one can with certainty say what is valid and what is the brilliant construct of a band of radical Jews suddenly deprived of a beloved leader, who, out of nothing but the richness of a desert faith, invented a religion that has dominated western history for nearly 100 generations.
That is my take on the Jesus represented in the thought-provoking book "Excavating Jesus" a work that showed how separated from the weight of myth, Jesus the figure was extremely interesting in the context of historic reality.
