“Do this in memory of me,” said Jesus at the Last Supper, according to the Gospel of Luke. But memories of Jesus the man have proved stubbornly elusive for historians who are convinced the truth of the son of God lies beneath the surface of Gospel accounts written decades after his death. Now, for the first time, one of America’s most prominent New Testament scholars has gone outside of his narrow field, driven as much by frustration as curiosity, to examine what the science of memory might offer to separate the historical wheat from the theological chaff in the Gospels. In so doing, University of North Carolina religious studies professor Bart Ehrman may have opened a new front in the currently quiescent Jesus wars, a quarter-century of devout and secular scholars battling over what, exactly, is the gospel truth.
