The Catholic Church has the fullness of the truth, other denominations have elements of the truth. Having perfect orthodoxy and a perfect knowledge of the things of God is great, but worthless without charity. All things being equal, love of God and neighbour and all, I don’t see why a decent fellow who was brought up in the Church of E should stand a lesser chance of being saved than the same fellow who was, through no merit of his own, brought up in the Catholic Church. “There is no salvation outside the Catholic Church” does NOT literally mean there is no salvation outside the Catholic Church.
Does this qualify as too literal (serious question btw)?
Saint Gregory the Great (590-604), Moralia: “Now the holy Church universal proclaims that God cannot be truly worshipped saving within herself, asserting that all they that are without her shall never be 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).
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 Sylvester II, Profession of Faith, June AD 991: “I believe that in Baptism all sins are forgiven, that one which was committed originally as much as those which are voluntarily committed, and I profess that outside the Catholic Church no one is saved.”
Pope Leo XII (1823–1829), Encyclical Ubi Primum: “It is impossible for the most true God, who is Truth Itself, the best, the wisest Provider, and rewarder of good men, to approve all sects who profess false teachings which are often inconsistent with one another and contradictory, and to confer eternal rewards on their members. For we have a surer word of the prophet, and in writing to you We speak wisdom among the perfect; not the wisdom of this world but the wisdom of God in a mystery. By it we are taught, and by divine faith we hold, one Lord, one faith, one baptism, and that no other name under heaven is given to men except the name of Jesus Christ of Nazareth in which we must be saved. This is why we profess that there is no salvation outside the Church… For the Church is the pillar and ground of the truth. With reference to those words Augustine says: ‘If any man be outside the Church he will be excluded from the number of sons, and will not have God for Father since he has not the Church for mother.’”
Pope Pius IX (1846–1878), Allocution Singulari Quadem, December 9, 1854: "Not without sorrow we have learned that another error, no less destructive, has taken possession of some parts of the Catholic world, and has taken up its abode in the souls of many Catholics who think that one should have good hope of the eternal salvation of all those who have never lived in the true Church of Christ. Therefore, they are wont to ask very often what will be the lot and condition of those who have not submitted in any way to the Catholic faith, and, by bringing forward most vain reasons, they make a response favorable to their false opinion. Far be it from Us, Venerable Brethren, to presume on the limits of the divine mercy which is infinite; far from Us, to wish to scrutinize the hidden counsel and “judgements of God” which are “a great abyss” (Ps. 35.7) and cannot be penetrated by human thought. But, as is Our Apostolic Duty, we wish your episcopal solicitude and vigilance to be aroused, so that you will strive as much as you can to drive form the mind of men that impious and equally fatal opinion, namely, that the way of eternal salvation can be found in any religion whatsoever.
