@Arjuna,
You want to know my take on this? (Probably not is my guess)
There was no virgin birth. There was an attempt to proclaim it a virgin birth to prevent her demise. Since the people in those days were cruel to women who gave birth outside marriage. The way to protect her was to proclaim the pregnancy an act of god. Then jesus being a bastard, would also not be accepted by society. This would cause a double situation. Since it is not openly accepted, he would become reclusive towards people and at the same time he could sympathize with others who are outcast by society (the sick, the deranged and the social outcasts) This would ultimately lead Jesus to become a rebel to the social norms and reject the fabric of the held belief system. He would question their behavior and ask the question, if these are gods people, why are they so cruel? Thus the abandoning of the jewish faith and the making of a new religion.
Why would a society lift a woman into the status of giving birth to the son of god unless she could be "better" than any other woman who existed?
"She never tainted herself with the impurity of sexual pleasure."
If sex is so impure and it only becomes pure if there is a loving connection, then why not say that she was in love? Why because it strips away (pun intended) the god's son effect. If Jesus was just the son of another human man then where does the divinity come from?
I believe there was a jesus but he is definitely not the legend that he is given today. We all know this is human behavior to exaggerate a renown individual. We raise the respect of a person far beyond their actual reality. Stories are invented and details are invented. It can't be refuted that this practice does not happen or that Jesus somehow escape such a response. I think anyone who claims that Jesus is an exception is nothing other than naive.
