The Pontifical Commission Ecclesia Dei has approved the Summorum Pontificum pilgrimage for Sept 14-17, 2017, with the Tridentine Rite Mass allowed to be offered only with the new ecclesiology.It accepts the dogma extra ecclesiam nulla salus as having known exceptions.
Priests who offer the Tridentine Rite Mass with the old ecclesiology based on the dogma extra ecclesiam nulla salus as having no objective exceptions in the present times, could be suspended.It would be ideological for the Vatican.
This has been mentioned to the Ecclesia Dei in the past and there has been no denial.
When the 16th century missionaries offered the Latin Mass it was with the old ecclesiology.The dogma extra ecclesiam nulla salus did not have any known or unknown exceptions for St.Francis Xavier.
However Pope Benedict announced a few months back that extra ecclesiam nulla salus is no more like it was for the 1th century missionaries. There were 'developments' with Vatican Council II. He meant that the baptism of desire etc refer to visible and not invisible cases. So it was an objective exception, it was inferred, to the traditional interpretation of the dogma which says all need to be incorporated into the Church as members.
So he was clear that there was a new theology based on known exceptions to the dogma extra ecclesiam nulla salus as promoted in the Letter of the Holy Office 1949 to the Archbishop of Boston.
The Letter says everyone does not need to be incorporated into the Catholic Church as a member while the dogma says the opposite.
So to interpret the dogma extra ecclesiam nulla salus as did Fr. Leonard Feeney and the St. Benedict Center is prohibited. This can no more be the ecclesiology of the priest offering the Latin Mass or the Novus Ordo Mass in 2017.
So the Mass approved by Ecclesia Dei for 2017 too in its ecclesiology is irrational, non traditional and heretical.
It has an impediment and yet for ideological reasons it is approved by Ecclesia Dei.It is magisterial according to the persons in the Vatican; the people. However it is a rupture according to magisterial documents including Vatican Council II (AG 7, LG 14).It is also a rupture according to the magisterium of persons in the past; the past Church Councils and popes.
