...there is nothing more important, or even in the neighborhood, of being clear about the nature of the soul being mortal and not subject to supernatural creation or control (the issue really may be "supernatural relation" rather than "supernatural control").
This is actually what prompted me to ask the question. Once someone has reached this conclusion it doesn't necessarily lead to the same ethical conclusions as Epicurus, but since he mentioned him by name I'm curious where Ehrman's thinking led him.
