Waitasec, using your criteria, then no written material concerning any person, place of thing from the concept of recording any material can be stated as "actual said or done". It is all a myth. However, "eyewithess accounts" are still held as reliable--especially, two or more "eyewitnesses". Again, no one is forcing you to believe anything. It has been shown that your suppositions are what is contrary to the recordings of the Scriptures.
There was two classes of audiences. Those who Believed (of the Jews and Gentiles) and those who disbelieved (of the Jews and Gentiles).
First, the Gospels were written as Luke stated,(1:1-3), "Forasmuch as many have taken in hand to set forth in order a declaration of those things which are most surely believed among us, Even as they delivered them unto us, which from the beginning were eyewitnesses, and ministers of the word; It seemed good to me also, having had perfect understanding of all things from the very first, to write unto thee in order, most excellent Theophilus","
second, Paul had this to say concerning the written history: 1Cor.10:6, 11, "Now these things were our examples, to the intent we should not lust after evil things, as they also lusted......Now all these things happened unto them for ensamples: and they are written for our admonition, upon whom the ends of the world are come."
And Rom.15:4, "For whatsoever things were written aforetime were written for our learning, that we through patience and comfort of the scriptures might have hope."
Yes, Jesus was, indeed, a very factual "legend"...."fulfilling" all that the prophets had written concerning HIM.
