In one of the earlier threads from the same paper, Adam makes a point about Luther's inability to consider, let alone grasp intellectually, doctrines that he internally disagreed with. I beleive that to be a very astute psycholigical observation because it explains Luther's breathless disregard for the bulk of the Gospel in building his sola fide theology from a few verses by St. Paul, and by insistence on amputating the Deuterocanon. It also ties with the Renaissance malady of putting man as the measure of everything, in the mind of Luther including, apparently, the Divine Revelation.
However, as a quick reply, Calvin provided the theological rigor Luther could not.
I don't disagree with this. This is an example of a careful use of psycho-history, interrelating it with theological reasoning. This is one of the strong points of Adam's work.
