I'm OK with Ehrman or anybody else concluding that Jesus existed. I think there's an even chance that there was a Galilean preacher named Jesus who was crucified by the Romans for sedition and who was later given divine status by his followers. Where I part company with Ehrman is his approach to demonstrating that Jesus existed. I think his reasoning is faulty and his evidence is very weak.
…gets plenty of disdain from those who dislike his conclusion that Jesus did not rise from the dead.
Ehrman evidently cannot win. While apologists love his saying that Jesus existed, they cannot stomach the Jesus that Ehrman said existed! Ehrman's "historical" Jesus was not a god and had no magical powers. As such, Ehrman's Jesus cannot save anybody from death.
So apologists grab whatever Ehrman says that they presuppose about Jesus and trash the rest.
I'm not so different from apologists in that regard. While I agree with Ehrman that there are historical difficulties with a Jesus, I cannot agree with his conclusion that "Jesus almost certainly existed."
