An original text rarely survives, but very often, copies are made of it. Until 1500 there was no other way then to just copy texts by hand. In this process, there were always changes made, either deliberatly (sometimes copyers made changes to things that fitted them better) or by accident. a good text tradition implies you either have the original text or have a good idea of how it must have looked like (by using different copies).
When you just have some copy of a source, you can never be sure wether this is the original text, and thus your info is flawed. A copyer, defenatly when he felt connected to the subject (wich is always the case in religion), can always make changes to provide proof or whatever...
A good text tradition, and thus a good knowledge of how the original text was like, is thus most important when you discuss the content of it.. Without it, your source is useless..
"I think what i'm sayign is that within 100-150 years of the person dying I think is reliable data, because it dosent leave room for people to make up legends about such things. If they had, they quickly would have been called out because the events are still somewhat fresh in people's memories. Now there are a dozen accounts during that time period and if you consider that the Jews really didn't like this idea of Jesus, any account that was false about him would have been attacked thoroughly by Jewish Pharises and Sadduces, and would haev been taken as a hoax."
That's a seriously dangerous statement. I could name you thousands of examples of people being turned into legends just after their death, or even while they were still alive
Reliable data doesn't exist either. Every way of communication is selective and deforms the reality. Minds deform things as well, it's a well-known fact that your mind only remembers what you found important, and that little bits are forgotten and "patched" with little made up facts. This is an automatic process, you can't control it..
Another thing, I wouldn't go as far as calling them "the Jews" as a single monolithic group, and I wouldn't defenatly conclude that sources were or weren't attacked, you can only guess... Especially if you say that they really didn't like him, they can as well make things up to make him look like a sorcerer or whatever..
To summarize: we have 2 sources that weren't directly involved into the whole situation, and they mention a Jesus, how he was killed and that he inspired people (wich explains the political trouble of that region in that time. That's where historical facts end about the man. When you go further, you can assume things, but they're not facts..
And this is where I reconciliate with Deci's statement: "there's no historical evidence of one jesus performing the things described in the bible. it's very common for religious people to shout "jesus was a historical person" and intentionally disregard that he was most likely many historical persons."
God: Behold ye angels, I have created the ass.. Throughout the ages to come men and women shall grab hold of these and shout my name...
