The Church can be considered as a communion and a Sacrament and this does not exclude it being the only path to salvation. The Church may be considered a Mystery but this does not exclude it having an exclusiveness and superiority in salvation.

Even if the Church is a communion, Sacrament, Mystery, Body of Christ and other things for Cardinal Ratzinger, the Church still is the only path to salvation ( Notification, CDF, Dupuis 2001) and outside the Church there is no salvation(Ad Gentes 7).The Church is still the only Ark of Noah that saves in the flood(CCC 845) and God wants all people to be united in the Catholic Church(CCC 845). The Church can be compared to a Door or the narrow gate(Matt.7:13-14)) in which all need to enter as members, with faith and baptism (AG 7, LG 14). to avoid the fires of Hell ( for salvation).

So the old ecclesiology of the Church has not changed after Vatican Council II.

The Church can be considered as a communion and a Sacrament and this does not exclude it being the only path to salvation. The Church may be considered a Mystery but this does not exclude it having an exclusiveness and superiority in salvation.

It is important to note that in the Catechism of the Catholic Church 848, Outside the Church there is no salvation, when it is said that all salvation comes through Jesus and the Church, this does not exclude all needing to enter the Church with faith and baptism for salvation(AG 7). Since there are no known exceptions to AG 7 in LG 8, LG 14, LG 16, UR 3, NA 2, GS 22 etc.-Lionel Andrades
