You said that I disagreed with the Church's on salvation and invincible ignorance.  I asked what you perceived the Church's to be; no answer.
I know that people do disagree with the Magisterium, one only has to read the numerous and diverse opinions which abound on here to see that people do that. Everyone is his own pope, his own church in deciding what to believe or not to believe. 
When one sees the diversity of belief and opinion expressed here, it is easy to understand how the churches of the Reformation disintegrated into the 40,000 odd Protestant sects which exist today. Without the Magisterium the Catholic Church would be in the same state.
We already have this to some extent insofar as people trumpet the virtues (or vices) of their particular parish (liberal, Vatican II; good: traditional, orthodox; bad).
Be mindful of Matthew 13:24-30. The tares have been sown, we await the reaper.
