Back to this census of Quirinus... frankly, i didn't know it, but wiki says this event was directly mentioned in Gospel of Luke:
"In those days a decree went out from Emperor Augustus that all the world should be registered. This was the first registration and was taken while Quirinius was governor of Syria. All went to their own towns to be registered. Joseph also went from the town of Nazareth in Galilee to Judea, to the city of David called Bethlehem, because he was descended from the house and family of David. He went to be registered with Mary, to whom he was engaged and who was expecting a child." - (Luke 2:1–7)
Excellent! Now we have a solid evidence that Jesus was born in the time of this census (6 or 7 CE)... but wait a minute! There is also a heartbreaking story of "Massacre of the Innocents":
"When the Magi had gone, an angel of the Lord appeared to Joseph in a dream. Get up, he said, take the child and his mother and escape to Egypt. Stay there until I tell you, for Herod is going to search for the child to kill him. So he got up, took the child and his mother during the night and left for Egypt, where he stayed until the death of Herod. And so was fulfilled what the Lord had said through the prophet: "Out of Egypt I called my son." When Herod realised that he had been outwitted by the Magi, he was furious, and he gave orders to kill all the boys in Bethlehem and its vicinity who were two years old and under, in accordance with the time he had learned from the Magi. Then what was said through the prophet Jeremiah was fulfilled: "A voice is heard in Ramah, weeping and great mourning, Rachel weeping for her children and refusing to be comforted, because they are no more." - (Matthew 2:16–18)
Excellent! Jesus was born under the reign of Herod, not later than 4 BCE, at least 10 years before the census of Quirinus... the Holy Bible said so!
Thus, let's be honest, we must admit that:
1) Gospels were written by those who personally knew Jesus, but at least one of two stories is deliberate lie. Or both stories, who knows... or:
2) Gospels were written by those who never knew Jesus and 1-2-3 generations after his death. Real authors of Gospels (clearly not Luke or Matthew) just confused some events (real and fictional), happened many years ago...
PS you guys may believe in whatever you want. But IMHO this all is a very questionable story... at least.
