That has to be the most ridiculous thing I've ever heard.
Which SPECIFIC Bible scholars have you been listening to lately, Kylie? Care to cite and quote a few since------------oh, by golly!--------------you insinuate that you just know so very, very much about the topic of justified true belief and historical warrant.

Your inferred conflation between evidence and proof is annoying. Have you ever studied Historiography? Or the Philosophy of History? Or the Historian's Craft?
Apparently not. If you had, you'd be able to cite some sources. But since you seem to rarely do so, I'm going to suppose you're merely a neophyte learner whose just trying to find her way through the maze and cobwebs of academia.
"We may define “faith” as a firm belief in something for which there is no evidence. Where there is evidence, no one speaks of “faith.” We do not speak of faith that two and two are four or that the earth is round. We only speak of faith when we wish to substitute emotion for evidence." Bertrand Russel.
Since I have supported my claim that the baptism and crucifixion of Jesus is all that Biblical scholars can say happened with anything near certainty (I gave you eight sources for that), then my statement here stands. If you hold that anything else is factual, then you are doing so with so little evidence not even Biblical scholars can agree that it happened. With such a lack of evidence, all you have is faith.
