There is one thing I have discovered–that those who do not wish to accept Jesus as the Christ will go as far as to deny even atheist scholars’ claims that He lived from around 4 B.C.E.-29 C.E. in ancient Palestine. One recently claimed that only a branch of scholars influenced by Christian apologetics accept the existence of Jesus. My sense is that someone who is ready to deny the vast majority of scholarship, not only Christian, but also atheist, agnostic, and Jewish scholarship, is unlikely to be persuaded by a blog post. I will summarize the evidence–first apart from the gospels:
Both Tacitus, Suetonius, and Pliny the Younger (in his letter to the Roman emperor Trajan, 112 C.E.) mention Jesus as the founder of Christianity and that he was crucified under Pontius Pilate. These are the sure references to Jesus in extrabiblical literature of the second century. There is a reference, though later edited by Christians, to Jesus in Josephus, a first century Jewish historian.
St. Paul, writing around 54 A.D. in I Corinthians, mentions the death, burial, and resurrection of Jesus. His letters all presume the existence of the historical Jesus only 25 years after his crucifixion. In addition, the four gospels, which may or may not have been written by the traditional authors–and that does not matter–give detailed descriptions of Jesus’ life–and all were written in the first century A.D. Despite differences in detail (which we also find in descriptions of Socrates, whose existence no one doubts, by Plato, Xenophon, and Aristophanes), which are to be expected in multiple accounts of any person’s life, most historical details fit the situation in Palestine during Jesus’ lifetime. Matthew and Luke made use of Mark and possibly a hypothetical document called Q (for Quelle, the German word for “source’), they also made use of oral tradition dating back to those who knew Jesus. The amount of time from Jesus’ life to the New Testament writings is incredibly short by standards for most religious figures such as Gautama Buddha or Confucius. Jesus’ existence is as well attested as the existence of most of the historical figures studied from the ancient world.
There is a great deal of pseudo-scholarship out there that denies Jesus’ existence, usually by means of assertion rather than argument. Mainstream scholarship of all creeds or lack thereof accepts Jesus existence–if we denied it on the critics’ grounds, we would have to deny the existence of Plato, Julius Caesar, Herod the Great, and other ancient historical people. The similarity of the Jesus story to dying and rising god stories proves nothing about Jesus existence. The critics are inconsistent–they demand absolute, quasi-mathematical proof for Jesus’ existence, but not for other historical figures they accept as having existing.
Why fly in the face of so much evidence? Probably denial of the obvious is an act of the will rather than an act of the intellect. People who want no part of Jesus find it easier to push him out of their world if they accept the view that he never existed. They are not interested in evidence, but in sophistry that may work with many people who are unaware of the evidence. I remember C. S. Lewis’ scene in The Last Battle, when Aslan throws Jewels at the dwarfs who reject him–they claim that the jewels are straw. Some individuals are so hardened that they refuse to listen to any evidence regarding Jesus, even for a position accepted by all serious Biblical scholars in the academy.
