Bart Ehrman (along with Elaine Pagels, a repeat go-to for early Christian thought, including Gnostic teachings) has a new book out. It was an interesting discussion of memory and how it affected how Christianity was remembered pre-gospels. Think the point was made about two-thirds the way in but overall he is as usual good reading. Again, do think the historian can examine miraculous beliefs, psychological and other techniques available to understand what "really happened." Plus, as part of history, it needs to be covered more than he does.
