CARDINAL GERHARD MULLER : MISTAKES HYPOTHETICAL REFERENCES AS BEING EXPLICIT IN THE PRESENT TIMES.
ARCHBISHOP AUGUSTINE DO NOIA : ASSUMES WHAT IS KNOWN ONLY TO GOD CAN BE KNOWN AND JUDGED BY US HUMAN BEINGS.
That has been discussed, but here, too, there has been a development of all that was said in the Church, beginning with St. Cyprian, one of the Fathers of the Church, in the third century. Again, the perspective is different between then and now. In the third century, some Christian groups wanted to be outside the Church, and what St. Cyprian said is that without the Church a Christian cannot be saved. The Second Vatican Council also said this: Lumen Gentium 14 says: “Whosoever, therefore, knowing that the Catholic Church was made necessary by Christ, would refuse to enter or to remain in it, could not be saved.” He who is aware of the presence of Revelation is obliged by his conscience to belong publicly — and not only in his conscience, in his heart — to this Catholic Church by remaining in communion with the Pope and those bishops in communion with him.
But we cannot say that those who are inculpably ignorant of this truth are necessarily condemned for that reason. We must hope that those who do not belong to the Church through no fault of their own, but who follow the dictates of their God-given conscience, will be saved by Jesus Christ whom they do not yet know. Every person has the right to act according to his or her own conscience. - Cardinal Gerhard Muller (10/02/2012 ).

I don’t know if you can blame this on the Council so much as the emergence of a theological trend that emphasized the possibility of salvation of non-Christians. But the Church has always affirmed this, and it has never denied it. …The Council did say there are elements of grace in other religions, and I don’t think that should be retracted. I’ve seen them, I know them — I’ve met Lutherans and Anglicans who are saints.' - Archbishop Augustine di Noia ( 07/01/2012 ), Archbishop Di Noia, Ecclesia Dei and the Society of St. Pius X, National Catholic Register.
BISHOP BERNARD FELLAY ASSUMES THEORETICAL POSSIBILITIES KNOWN ONLY TO GOD ARE EXPLICIT IN THE PRESENT TIMES AND RELEVANT TO EENS
The same declaration (LG, 8) also recognizes the presence of “salvific elements” in non-Catholic Christian communities. The decree on ecumenism goes even further, adding that “the Spirit of Christ does not refrain from using these churches and communities as means of salvation, which derive their efficacy from the fullness of grace and truth entrusted to the Catholic Church.” (UR, 3)
Such statements are irreconcilable with the dogma “No salvation outside of the Church, which was reaffirmed by a Letter of the Holy Office on August 8, 1949". -Bishop Bernard Fellay (April 13, 2014 ) Letter to Friends and Benefactors no. 82
