I believe that the purpose the author was trying to show was in a way a joke relative to that of the bible, and how Barbie is not just a toy, but a life glorified and personified through a narrow glamorous window of society.  The author is trying to reveal also the major changes, additions, and inclusions in the world of Barbie, to show that although the side it reveals to the world is narrow, it is attempting to expand. The problem arrives though with a seeming drop off at the end, showing perhaps Barbie has run her course and its time to stop. The perceptive, though once cutting edge is almost seemingly as old as the verse the author was parodying.  In a world of changing gender roles and inclusion, can Barbie truly survive? will it go too far? I think this is the point of the author. I fake sense of of piety covered by sadness and perhaps disgust in the fact that although once Barbie may have been a cultural icon, it was always laced with controversy, and not even more of it seems to be leaking out in this day and age. Either Barbie must conform to reality, or fade away.
