"There is a long history of just such usage. The pilgrim fathers who came to America read their situation into the Bible (or the Bible into their situation) with the result that white pilgrims were seen as fulfilling the role of the Israelites in this, the Promised Land, while native Americans were cast in the role of Canaanites. Thus generations of Joshuas arose feeling Biblically justified in the genocide of America’s native population. Some of that Biblical reading continues to echo in the popular imagination to this day. It was Bad theology in the 17th century and it is bad theology today. Stated in a fundamental way: you are not a Bible character."Sanford's arrogance is, unfortunately, not rare in evangelical circles. Palin tried to compare herself to Esther (since evidently Esther was also proud of her ignorance?), and Tom Delay once compared his experience to that of Christ.
If Bill Clinton did that, the evangelicals would freak out. If Obama did it, their heads would asplode. But somehow, when one of their own does it, they just nod along.
