Jeez Louise, this guy is a real crank.
The "chosen one", "guy with god on his side", "got superpowers because his cause is just" is as old a device as it gets.
On these grounds modern western readers are just as degenerate as their medieval ancestors.
Most of the Medieval works show us as all too human. The idea of the Superman is far more Pagan stemming from ancient myths and legends. Arthur, Cuchulain, and Beowulf fall on the pagan side, while the Decameron and Canturbury Tales are more classically Medieval.
