A clear "NO" will become an ambiguous "MAYBE".
The end of the ordinary magisterium
If one Pope can officially contradict his predecessors' ordinary magisterium, then:
It is impossible.
And if one Pope can officially contradict his predecessors in fundamental matters related to doctrine, morals and the sacraments, then:
- What authority does the ordinary magisterium possess?
I'd say that bergoglism will make whatever a Pope says or writes - short of defining a dogma - completely irrelevant, because one of his successors may come along and reverse whatever he taught.
The democracy of relativism
It will then be up to each individual member of the flock to determine if a particular teaching is to be adhered to or not. (In fact, that's what's been going on since '68, but up until now the Popes had never done anything to legitimize this course of action.)
Of course, for faithful catholics Tradition will be the rule of Faith.
For others it will be a matter of individual opinion, taste, fashion ... and the media/entertainment industrial complex will push them in the 'right' direction.
The democracy of relativism will be given its declaration of independence and Pope Francis will become its founding father.
