I don't know if the Hispanic-world gets what your point is because most don't even know anyone that is not Catholic.How many of you have seen these dogmatic statements about there being NO SALVATION OUTSIDE THE CATHOLIC CHURCH?
“There is but one universal Church of the faithful, outside which no one at all is saved.” (Pope Innocent III, Fourth Lateran Council, 1215.)
“With Faith urging us we are forced to believe and to hold the one, holy, Catholic Church and that, apostolic, and we firmly believe and simply confess this Church outside of which there is no salvation nor remission of sin… Furthermore, we declare, say, define, and proclaim to every human creature that they by absolute necessity for salvation are entirely subject to the Roman Pontiff.”
(Pope Boniface VIII, Unam Sanctam, Nov. 18, 1302)
“The most Holy Roman Church firmly believes, professes and preaches that none of those existing outside the Catholic Church, not only pagans, but also Jews and heretics and schismatics, can have a share in life eternal; but that they will go into the eternal fire which was prepared for the devil and his angels, unless before death they are joined with Her; and that so important is the unity of this ecclesiastical body that only those remaining within this unity can profit by the sacraments of the Church unto salvation, and they alone can receive an eternal recompense for their fasts, their almsgivings, their other works of Christian piety and the duties of a Christian soldier. No one, let his almsgiving be as great as it may, no one, even if he pour out his blood for the Name of Christ, can be saved, unless he remain within the bosom and the unity of the Catholic Church.” (Pope Eugene IV, the Bull Cantate Domino, 1441.)
If anyone says that true and natural water is not necessary for baptism and thus twists into some metaphor the words of Our Lord Jesus Christ: “Unless a man be born again of water and the Holy Ghost, he cannot enter into the kingdom of heaven,” let him be anathema. (Council of Trent: Canon 2 of the Canons on Baptism, 7th Session, Sacrament of Baptism)
"If anyone shall say that baptism is optional, that is, not necessary for salvation (cf. John 3:5): let him be anathema." (Council of Trent: Canon 5 of the Canons on Baptism, 7th Session, Sacrament of Baptism)
“If anyone says that true and natural water is not necessary for baptism and thus twists into some metaphor the words of our Lord Jesus Christ: Unless a man be born again of water and the Holy Ghost, let him be anathema.” (Council of Trent: Canon 2 of the Canons on Baptism, 7th Session, Sacrament of Baptism)
The faith which God has revealed has not been proposed like a theory of philosophy, to be elaborated upon by human understanding, but as a divine deposit to be faithfully guarded and infallibly declared. Therefore, that sense of sacred dogmas is to be kept forever which Holy Mother Church has once declared, and it must never be deviated from on the specious pretext of a more profound understanding. Let intelligence, and science, and wisdom increase, but only according to the same dogma, the same sense, the same meaning. If anyone shall have said that there may ever be attributed to the doctrines proposed by the Church a sense which is different from the sense which the Church has once understood and now understands: let him be anathema.(I Vatican Council)
While there are many who have become Protestant especially in Brazil. I don't think most Catholics consider them "outside" the Church because they are still "christian".
