In case you missed it, here’s a fascinating post by Larry Hurtado, based on a very interesting article by Leander Keck about whether we should consider the New Testament as a ‘field of study’ separate from other early Christian literature. Hurtado’s conclusion is particularly interesting to me:
In short, for theological purposes the NT is (and should be) a “privileged” body of texts. But for historical purposes we should both take account of the breadth and diversity of early Christian literature and also the dynamics that from a remarkably early point gave to certain texts a special status and authority among at least many (most?) early Christian circles.
