His life is very well documented. Some of the surviving documentation that exists was written by the man himself.
Even though he's been dead for over 2000 years, he is still one of the most studied figures in History.
Don't believe me? Think there is some detail that I've yet to mention? Of course there is. Most people who study him today don't call him by the name Jesus Christ, they refer to him by the name he went by at the time he was alive, Julius Caesar.
Here are some excerpts from a recent book on the subject
http://www.carotta.de/eindex.htmlHere's a good review of the book
http://www.smallkidtime.com/was_jesus_caesar.htmI haven't read the book yet, it is next on my reading list after The Elegant Universe. There is, however a great deal of information on the authors website. The theory isn't new. I first came across it about three or four years ago and became fascinated by it. I've seen the topic come up on various Religious message boards and so far no one has given any sort of semi-factual rebuttal to show that the theory might be wrong. The three most common arguments against it so far are:
1. Julius died before Jesus was born, so the two could not be the same person.
This might be a good argument if it weren't for the fact that the only thing theologians can agree on when it comes to the birth of Jesus is that the Bible gives conflicting information. I've heard dates for the birth of Jesus quoted anywhere from 50 B.C. to 50 A.D., with the most common being around 7 B.C. Secondly, if the Cult of Divus Julius was transformed into the Cult of Jesus Christ, the timing fits extremely well, about two Generations.
2. The Bible was written before Julius Caesar was born.
I've seen this one several times which just goes to show that most so called Christians don't know much about Christianity, or History. Julius Caesar Born 100 B.C. died 44 B.C. Jesus Christ born approx. 7 B.C. died approx 28 B.C. New Testament to the Bible written after Jesus' death.
3. (This one is my favorite) Nuh-Uh. You're a stinky poopy-head, go away.
I've read a number of theories about the historical basis of Jesus and this one, to me, is by far the most compelling. There are just too many parallels between the two characters, both big and small. The timing of it all is perfect. And while the Jesus of the Bible might have been a simple carpenter from Palenstine, no one can deny that the heart and soul of the early days of Christianity was the Roman Empire.
Oh, and as for whether or not Jesus was a liberal, the truth, as I believe it to be, is that Jesus was neither liberal or conservative, but instead one hell of a Politician.
