Brandon Mouser has a great post on his blog and I wanted to continue to interact by posting this reply…it got a little long for a combox:
Basically, what I would point to is the idea that Scripture claims for itself the idea of being “theopneustos,” or “breathed out by God.” Bart Ehrman and others have erroneously postulated that thiswould have to mean that God dictated the Scriptures, much like many non-Christian sects claim their Scriptures were written. Instead, it points to divine agency being played out in the words used by human beings. This sort of inspiration is unique to the Scriptures, though the norm amongst biblical authors in the writings which were recognized by the Church as being authoritative.
