False.I guess there is no consensus on climate change? Consensus doesn't mean every single individual on the planet, could be where you've gone wrong here...This is false. The consensus is that there probably was a man named Jesus. This is extremely common knowledge, and no one who thinks otherwise has spent five minutes honestly looking at the situation.

The quotes have some issues.
As pointed out on the Christ Myth wikipedia talk page Michael Grant is actually quoting Otto Betz (from 1968) who in turn was parroting Roderic Dunkerley from 1957 and we have NO idea where Dunkerley got his information. We have seen this nonsense with the Bermuda Triangle myth where each new writer just parrots the previous writer.
"This view [that Jesus didn’t exist] is demonstrably false. It is fuelled by a regrettable form of
atheist prejudice..." - Maurice Casey
"In the Far East where the major religions are Buddhism, Shinto, Taoism and Confucianism, Jesus is considered to be just another character in Western religious mythology, on a par with Thor, Zeus and Osiris."
So Buddhists, Shintoists, and Taoists are all atheists...

Do I need to go in just how STUPID that is?
"I don’t think there’s any serious historian who doubts the existence of Jesus" - Bart Ehrman
No True Scotsman fallacy. What about people who put Jesus outside of the normal time frame who were call Christ Mythists?
"The historical evidence for Jesus himself is extraordinarily good." - NT Wright
Snicker, giggle, BAHAHAHA. You're NOT kidding?
"some judgments are so probable as to be certain; for example, Jesus really existed, and he really was crucified, just as Julius Caesar really existed and was assassinated" - Marcus Borg
I have already demonstrated the insanity of
that position.
M A Powell give us the old Holocaust comparison and I have gone on how intellectually bankrupt
that position is.
Jeffery Jay Lowder's quote is missing these leading sentences: "There simply is nothing epistemically improbable about the mere existence of a man named Jesus. (Just because Jesus existed does not mean that he was born of a virgin, that he rose from the dead, etc.)"
Heck, Carrier says that the passover part of Mark's story is based on a "man named Jesus": Jesus ben Ananias.
"An ancient historian has no problem seeing the phenomonon of Jesus as an historical one. " - Emeritus Professor Edwin Judge
And they also had no problem seeing Zeus, Heracles, and Osiris as being once real living people either.
James Charlesworth is Professor of New Testament Language and Literature; a degree in Linguistics would not necessarily make him an expert in history, archeology, or anthropology.
