Did you see John Paul II in Paradise? Of course not. We cannot know if John Paul II is really a saint only because there is a canonization.
The issue is are there any exceptions to the dogma extra ecclesiam nulla salus. Is the baptism of desire an exception to all needing Catholic Faith and the Baptism of water ?The dogma says every one needs to convert into the Church for salvation. Do we know any one saved outside the Church, who does not need to convert?
So when someone says the baptism of desire is an exception to the dogma extra ecclesiam nulla salus he is implying that there is a case of a person saved with the baptism of desire and this case is known and visible to us. So it is an exception to all needing the baptism of water for salvation.
So is there a visible case? Can we see someone dead who is now saved in Heaven with the baptism of desire ? No we cannot.
Even those who have been canonised saints are not visible to us in the flesh. We accept them as saints in faith.
So the baptism of desire, being saved in invincible ignorance(LG 16), imperfect communion with the Church (UR 3), a ray of the Truth (NA 2) etc are not visible to us and so they are not exceptions to extra ecclesiam nulla salus.
This was the error of the Letter of the Holy Office 1949.It has led millions of Catholics into error when interpreting Vatican Council II.
The Society of St.Pius X (SSPX) assumes that being saved with ' a ray of the Truth'(NA ) is VISIBLE to us. So it becomes a known exception to extra ecclesiam nulla salus.
The Vatican Curia assumes that all salvation mentioned in Vatican Council II (NA 2,UR 3,LG 16,LG 8,UR 3 etc) are VISIBLE to us.So Vatican Council II contradicts the dogma extra ecclesiam nulla salus.
The Vatican wants the Franciscan Friars and Sisters of the Immaculate to accept this irrational interpretation of Vatican Council II.
