“Legends do not generally arise in contradiction to fundamental convictions held by the culture of those who create and embrace them. Yet if the Jesus story is largely a fictitious legend, this is exactly what we must suppose happened. We submit that the initial historical implausibility of this supposition should be enough for us seriously to consider alternative explanations.”
“One such explanation is the one given us by those who first told the Jesus story. It is simple and straightforward, and it explains all that needs to be explained–though it requires that we accept the reality of the supernatural. In essence, the earliest disciples tell us that they report what they do about Jesus (despite its conflict with their own cultural/religious expectations) because this is how things actually happened. Most importantly, they tell us they believe Jesus is the Son of God and worship him as Lord because, though it violates some of their most fundamental Jewish religious convictions to do so, his life, teachings, miracles, and resurrection convinced them.”
