Well there's a fair chance that much of the four gospels is also myth. The jury's definitely out on whether Jesus even existed at all, and there are some pretty irreconcilable inconsistencies between the four accounts. It seems to me that, as the accounts were written long after the death of Jesus, they are most likely not intended to be historical documents, more a tendentiously produced manifesto for a new religion. Much of what Jesus is alleged to have said resonates with me, too, but some of it doesn't. Sufficient unto the day is the evil thereof, and turning the other cheek to someone who's attacked you, sound suspiciously like hippie philosophy to me.
