I don't recall seeing you on the RF threads before, but let me assure you it IS a pretty regular occurrence. I'll make a note of it to ping you to such postings so you can see for yourself. I also am pinging others so that they might do the same for you. I wholeheartedly agree that any FRoman Catholics who state such things ARE quite incorrect. Glad you agree.
Fourth Lateran Council (1215): "There is but one universal Church of the faithful, outside which no one at all is saved."
Pope Boniface VIII, Bull Unam sanctam (1302): "We are compelled in virtue of our faith to believe and maintain that there is only one holy Catholic Church, and that one is apostolic. This we firmly believe and profess without qualification. Outside this Church there is no salvation and no remission of sins, the Spouse in the Canticle proclaiming: 'One is my dove, my perfect one. One is she of her mother, the chosen of her that bore her' (Canticle of Canticles 6:8); which represents the one mystical body whose head is Christ, of Christ indeed, as God. And in this, 'one Lord, one faith, one baptism' (Ephesians 4:5). Certainly Noah had one ark at the time of the flood, prefiguring one Church which perfect to one cubit having one ruler and guide, namely Noah, outside of which we read all living things were destroyed… We declare, say, define, and pronounce that it is absolutely necessary for the salvation of every human creature to be subject to the Roman Pontiff."
Pope Eugene IV, Cantate Domino (1441): "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" (Matthew 25:41), 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 Pelagius II (578-590): "Consider the fact that whoever has not been in the peace and unity of the Church cannot have the Lord… Although given over to flames and fires, they burn, or, thrown to wild beasts, they lay down their lives, there will not be (for them) that crown of faith but the punishment of faithlessness… Such a one can be slain, he cannot be crowned… [If] slain outside the Church, he cannot attain the rewards of the Church" (Denzinger, 469).
And currently.
Second Vatican Council, Dogmatic Constitution Lumen gentium, 14: "They could not be saved who, knowing that the Catholic Church was founded as necessary by God through Christ, would refuse either to enter it, or to remain in it."
The Latin phrase extra Ecclesiam nulla salus means: "outside the Church there is no salvation".
