Archbishop Gerhard Muller has said that 'a reconciliation with the Society of Saint Pius X is possible'.
The Congregation had presented [the SSPX] with a clear dogmatic preamble; 'this door is open, we do not close it,' says Müller. 1
The door is open and the scenario has changed for the SSPX doctrinally. Traditionalists now accept that Archbishop Marcel Lefebvre unintentionally made a doctrinal error is assuming there were known exceptions to the dogma extra ecclesiam nulla salus.He innocently extended this error to the interpretation of Vatican Council II.
Without this factual error we have a rational interpretation of Vatican Council II which is in perfect agreement with the dogma extra ecclesiam nulla salus. Ad Gentes 7 affirms the dogma on exclusive salvation in the Church. While Lumen Gentium 16, Lumen Gentium 8, Unitatis Redintigratio 3 are not known exceptions to the dogma. They are irrelevant to the traditional, centuries-old interpretation.
Vatican Council II does not contradict the traditional Church teaching on other religions and Christian communities.
So the SSPX leaders could approach the 'open doors' with this understanding of Vatican Council II .They have already accepted the Doctrinal Preamble and they affirm the Nicene Creed.
They could ask the CDF Prefect if “religiosum obsequium… religious submission” in will and intellect to the Magisterium, means accepting a Vatican Council II which does not contradict the dogma extra ecclesiam nulla salus.This would include accepting a Vatican Council II in which it is not assumed that the dead now saved in Heaven, are physically visible to us and so are known exceptions to the dogma on exclusive salvation.
It will also mean that in the Nicene Creed when we refer to 'one baptism for the forgiveness of sin' we are referring to one known baptism only ; the baptism of water. There is only one known baptism, which is visible and repeatable. There are not three known baptisms. The baptism of desire and blood are known only to God.
Also when when we pray 'I believe in the Holy Spirit' it must be clear to all that the Holy Spirit does not claim that we can physically see the dead -saved , nor expects us to follow or teach this irrationality.
When we refer to 'the Holy Catholic Church' in the Nicene Creed, we are referring to the Catholic Church outside of which there is no salvation. There are no known 'elements of sanctification and grace' (LG 8) outside its visible boundaries.Neither is there known salvation outside the Church with 'seeds of the Word' (AG 11 etc), nor with ' imperfect communion with the Church'(UR 3). LG 8, UR3, LG 16 refer to possibilities and not exceptions to the dogma defined three times.They are always implicit and never explicit for us.
The 'doors are open' for the SSPX to bring the Church back to Tradition! This new development must be a nightmare for the liberals.They cannot cite Vatican Council II to back their dissent, unless they are implying the dead are visible to us on earth.
