We get our history of Jesus after the fact from believers or a scant few tidbits that aren't really conclusive.
Josephus 94 AD, Tacitus 20 years later a few others.
Josephus nor Tacitus, neither of which were Christian and were both well known historians, had no doubt that Jesus was actually a man who lived and was crucified under Pontius Pilate.
So yes, it is possible to think that the entire idea of Jesus is a construct, or loosely based upon someone that was real, or something like that.
It is also possible you are dreaming right now, but why think that if all of the evidence points to the conclusion you are awake?
The person of Jesus as you understand him is utterly difficult to show to have existed outside of simple reliance on the Gospels.
Undeniable? Hardly.
Jesus as I understand Him is described below:
Jesus (
/ˈdʒiːzəs/;
Greek: Ἰησοῦς
Iesous; 7–2 BC to 30–36 AD), also referred to as
Jesus of Nazareth, is the central figure of
Christianity.
Virtually all modern scholars of antiquity agree that a historical Jesus existed.
In a 2011 review of the state of modern scholarship,
Bart Ehrman (who is a secular agnostic) wrote:
"He certainly existed, as virtually every competent scholar of antiquity, Christian or non-Christian, agrees".
[15]
Richard A. Burridge states:
"There are those who argue that Jesus is a figment of the Church's imagination, that there never was a Jesus at all. I have to say that I do not know any respectable critical scholar who says that any more".
[16]
Robert M. Price (an atheist who denies existence) agrees that this perspective runs against the views of the majority of scholars.
[17]
James D. G. Dunn states that the theories of non-existence of Jesus are "a thoroughly dead thesis".
[18]
Michael Grant (a
classicist) states that "In recent years, 'no serious scholar has ventured to postulate the non historicity of Jesus' or at any rate very few, and they have not succeeded in disposing of the much stronger, indeed very abundant, evidence to the contrary".
[19]
Robert E. Van Voorst states that biblical scholars and classical historians regard theories of non-existence of Jesus as effectively refuted.
