The notion of the existence of an historical Jesus is bullshit!
But don’t take my word for it. Here’s some evidence (Did a historical Jesus Exist? by Jim Walker) from a great site my friend recommended. NoBeliefs dot com. It’s also linked in the Atheist Resources page.
Some choice bits:
“No one has the slightest physical evidence to support a historical Jesus; no artifacts, dwelling, works of carpentry, or self-written manuscripts. All claims about Jesus derive from writings of other people. There occurs no contemporary Roman record that shows Pontius Pilate executing a man named Jesus. Devastating to historians, there occurs not a single contemporary writing that mentions Jesus. All documents about Jesus came well after the life of the alleged Jesus from either: unknown authors, people who had never met an earthly Jesus, or from fraudulent, mythical or allegorical writings. Although one can argue that many of these writings come from fraud or interpolations, I will use the information and dates to show that even if these sources did not come from interpolations, they could still not serve as reliable evidence for a historical Jesus, simply because all sources about Jesus derive from hearsay accounts.”
“Even in antiquity people like Origen and Eusebius raised doubts about the authenticity of other books in the New Testament such as Hebrews, James, John 2 & 3, Peter 2, Jude, and Revelation. Martin Luther rejected the Epistle of James calling it worthless and an ‘epistle of straw’ and questioned Jude, Hebrews and the Apocalypse in Revelation. Nevertheless, all New Testament writings came well after the alleged death of Jesus from unknown authors (with the possible exception of Paul, although still after the alleged death).”
“Virtually all other claims of Jesus come from sources outside of Christian writings. Devastating to the claims of Christians, however, comes from the fact that all of these accounts come from authors who lived after the alleged life of Jesus. Since they did not live during the time of the hypothetical Jesus, none of their accounts serve as eyewitness evidence.”
