JP II ran the church like the communists ran Poland.  He believed  only in his own understanding.  He didn't read much---he didn't have the time.  You can play your "understanding" of the Magisterium all you wish.  Nobody wants the Vatican to rule over them like tyrants.  That was not in the Gospels.  The exalted Magisterium has no more to do with God than rats crawling in sewers.
