There cannot be a development of doctrine based on a false premise : this would be deception

Professor Matthew Ramage in 

Extra Ecclesiam Nulla Salus and the Substance of Catholic Doctrine:Towards a Realization of Benedict XVI’s “Hermeneutic of Reform” does not realize that invisible baptism of desire, baptism of blood and being saved in invincible ignorance cannot be a visible exception to the dogma extra ecclesiam nulla salus(EENS).

This is the false premise in his thesis here.

He is not also aware that the irrational premise, unknown people are known  in the present times, was also unfortunately accepted at Vatican Council II.

So there cannot be a development of doctrine based on these objective errors in Vatican Council II and the Letter of the Holy Office 1949.

Without this factual error Vatican Council II is not a rupture with traditional EENS. This could not be observed by Matthew Ramage because he was not aware of the false premise he is using.
