I like the way Peter Enns articulates the problem of myth and biblical studies, especially given our discussions on the term.
The Following is from Page 40 of Inspiration and Incarnation:
Christians recoil from any suggestion that Genesis is in any way embedded in the mythologies of the ancient world. On one level this is understandable. After all, if the Bible and the gospel are true, and if that truth is bound up with historical events, you can’t have the beginning of the Bible get it so wrong. It is important to understand, however, that not all historians of the ancient Near East use the word myth simply as shorthand for untrue, made-up, [or] storybook. It may include these ideas for some, but many who use the term are trying to get at something deeper. A more generous way of defining myth is that it is an ancient, premodern, prescientific way of addressing questions of ultimate origins and meaning in the form of stories: Who are we? Where do we come from?
I think that is a definition we can all agree upon, no?
