Of course there are no papal dogmatic or doctrinal statements that try to trump God by claiming that salvation is impossible for non-Catholics – every papal explanation, Vatican II and the CCC refute that – they are like the Council of Florence: Decree for the Jacobites , 1442:
“….we can see from the vehemence of Patristic attacks on heretics, e.g., St. Cyprian “Ad Demetrianum,” that the Fathers have in mind those who are in bad faith, who culpably reject the Church. They do not seem to think of those who in-culpably fail to find the Church.[27] So from this point on, it becomes largely a question not of doctrine but of objective fact: how many are culpable? Further, this statement was made in 1442, before the 1492 discovery that there was a whole other world. The writers thought that the Gospel had actually reached every creature – it had not – and supposed, as we said, bad faith on the part of those who rejected it.” [Fr William Most; my emphasis].
How strange that tradycja should want to trump popes, counseling on salvation of non-Catholics, with St Thomas Aquinas – that’s what prejudice produces. William James made a great observation –“many who think they are thinking are merely rearranging their prejudices.” How true.

He has explained that the Latin extra can mean either “without” or “outside” and, with the Magisterium, gives the true meaning of the possibility of salvation for non-Catholics. His contribution to the ECD (OSV) explains.
“Extra Ecclesiam, Nulla Salus” • What are we to say about those who, lacking Baptism, are not members of the Church in any of the senses explained above? Here it is necessary to clarify the meaning of an old theological principle whose interpretation has caused difficulty in the past: Extra ecclesiam, nulla salus (literally, “outside the Church, there is no salvation”). Some people have wished to understand this saying in the most literal sense: that is, that the person who is not formally a practicing Catholic cannot be saved. The Church has condemned such an interpretation (cf. Denzinger-Schönmetzer, 3870-3873).
This is not to say that the maxim is false. Properly understood, it is quite true. The Latin word extra can mean either “without” or “outside.” The correct interpretation and sense of the maxim is that we cannot be saved without the Church. It is through the Church, which carries on and makes present the salvific work of Jesus Christ in the world, that all who are saved reach heaven (even if it is perhaps only there that they realize it). Those who, through no fault of their own, have never known Christ or his Church can still be saved. But their salvation, too, is the effect of Jesus working through his Church. In a positive sense, this theological principle “means that all salvation comes from Christ the Head through the Church which is his Body” (CCC 846).

From the Holy Office:
“It is not always required that one be actually incorporated as a member of the Church, but this at least is required: That one adhere to it in wish and desire. It is not always necessary that this be explicit…. But when a man labours under invincible ignorance, God accepts even an implicit will, called by that name because it is contained in the good disposition of soul in which a man wills to conform his will to the will of God.”
“Therefore, let them who in grave peril are ranged against the Church seriously bear in mind that after “Rome has spoken” they cannot be excused even by reasons of good faith.

F. Cardinal Marchetti-Selvaggiani.
