Don't care enough to read through every post, I'm just going to post my thoughts on the Virgin Birth:
The Virgin Birth story was an attempt to cover up Jesus' inception, which was unacceptable to Jewish Law. Jesus' real father and mother had more than likely conceived out of wedlock, maybe Mary was even a prostitute.
Mark 6:1-3 below:
1 Then He went out from there and came to His own country, and His disciples followed Him. 2 And when the Sabbath had come, He began to teach in the synagogue. And many hearing Him were astonished, saying, Where did this Man get these things? And what wisdom is this which is given to Him, that such mighty works are performed by His hands! 3 Is this not the carpenter, the Son of Mary, and brother of James, Joses, Judas, and Simon? And are not His sisters here with us? So they were offended at Him.
In the traditions of that day, who would refer to a man as the "Son of [mother's name here]"? It was tradition to use the father's name, especially in Judaism. The only reason they would refer to Jesus as the "Son of Mary" is that if they didn't know who his father was. That statement in Mark 6:3 was a reference to Jesus' embarrassing conception, and was used as an insult against Him and His word.
The Virgin Birth cannot make any biological sense, unless semen was artificially implanted onto Mary's eggs, a technique that did not exist in first century Nazareth, or Bethelem, or wherever you believe Jesus was conceived. Even if Mary magically received the semen, Jesus would still break her hymen during the birth!
The complete illogicality of the Virgin Birth has not gone unnoticed through the centuries, so people looked for other explanations. In the Middle Ages, rumor spread that Jesus was born out of Mary's ear, and was regarded as a perfectly acceptable theory!
The fact is, as a Christian living in the 21th century, I cannot believe the Virgin Birth. Biology wins over liturgy.
