‘deconstruct the Bible by claiming that the discredited position that the Egyptian Book of the Dead is the source material for the biblical Book of Samuel,’
Come again?
The linked article gives an excellent rebuttal to this most inane of postmodern atheist arguments.
The general argument is that if even a small portion of an opposing argument is untrue, then the entire remainder is also untrue.
In this specific sense, the professor argued (like so many fresh-faced New Internet Atheists) is arguing that the entire Bible is fiction because a small portion is fiction.
This is simply a lie.
The “evidence” used is that a small portion of the Bible resembles the Egyptian Book of the Dead, a book that Christians would say is fiction.
Resemblance has nothing to do with truth. Causation is entirely different than correlation, as any of these little pipsqueak atheists can tell you once the shoe is on the other foot.
