If you are interested in the scholarship relating to those who claim Jesus never existed I would (somewhat selfishly) recommend my book, 'I Am Christ: Volume 1: The Crucifixion-Painful Truths. It is due to be released in Fall/Autumn this year by Charles River Press and outlines most of the scholarship and common sense arguments of the Jesus myth theorists. I am no Jesus Myth theorist myself, however, in the words of The Professor of Archaelogy at Washington University, and Biblical Archaelogist, Eric H. Cline:
"Archaeology has not yet been able to shed any direct light on the birth, life, or death of Jesus. That is to say, there is not yet any archaeological evidence for the historical Jesusor any of the apostles for that matter
. However, the failure of biblical archaeologists and pseudo-archaeologists to provide confirmatory evidence of the life of Jesus and the apostles has not been for lack of trying."
Further according to the Encyclopedia of World History:
"First of all, there are no contemporary archaeological or epigraphic remains that prove Jesus existence. What research has found corroborates the background of the New Testament but does not confirm its hero. Second, there are two literary recordsthe Talmud and Josephusthat speak about Jesus from a Jewish perspective, but both of these have been called into question."
In my book I outline the tip of the ice-berg with regards to the very solid scholarship which proposes Jesus did not exist, or at least, the Jesus of the Gospels did not, so I guess you can choose to investigate, or receed into the comfort of your belief and block out evidence which comes into conflict with your belief or you could seek! It is up to you, for your belief is not the truth, just your subjective opinion of it!
