Open debate: What does Jesus teach?

[Minimalist]

The New Testament was compiled long after Jesus, sure, but the material that was in it came about much earlier.

Evidence?

Any actual first century manuscripts? Any actual commentary by disinterested 3d parties? Are there even any off-hand comments by Greco-Roman writers which can reliably point to any element of the jesus story? Any archaeological findings from the first century?

You've got one book....and you try to use it to prove itself.
