"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 246-247)

"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." (Moralia)

"Indeed, there is but one universal Church of the faithful outside of which no one at all is saved." (Pope Innocent III, Fourth Lateran Council, 1215; Denz. 151)

"With our hearts we believe and with our lips we confess but one Church, not that of the heretics, but the Holy Roman Catholic and Apostolic Church, outside which we believe that no one is saved." (Denzinger 423)

"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." (Denz. 469) [note: This definition (de fide definita) seems unanswerable, but the liberals boldly claim that this is not a definition intended for the universal Church, but only a pronouncement meant to deal with the local problem of Philip the Fair. But when Philip demanded of Pope Clement V, the first Avignon Pope, that he withdraw Unam Sanctam, Pope Clement did not do so, but issued the Brief Meruit February 1, 1306, which despite its extremely conciliatory tone, clearly states that Unam Sanctam contains a "definition":] "That is why we do not wish or intend that any prejudice be engendered for that king and kingdom by the definition and declaration of our predecessor Pope Boniface VIII of happy memory, which began by the words Unam Sanctam." (51 Corpus Juris Canonici, (Extravag. commun., lib. V, tit. VII, cap. 2) ed. Freiburg, Vol. II, p. 1300.)

"Where the necessity of salvation is concerned all the faithful of Christ must be subject to the Roman Pontiff, as we are taught by Holy Scripture, the testimony of the holy fathers, and by that constitution of our predecessor of happy memory, Boniface VIII, which begins Unam Sanctam." (Pope Leo X, Fifth Lateran Council (1512-1517) Conciliorum Oecumenicorum Decreta, Edidit Centro di Documentazione, Instituto per Science Religiose, Herder, Bologna, 1962, no. 40, pp. 619, 620.)

"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.'" (Encyclical, Ubi Primum)

"It must be held by faith that outside the Apostolic Roman Church, no one can be saved; that this is the only ark of salvation; that he who shall not have entered therein will perish in the flood." (Denzinger 1647)

"By the ministry of this Church so gloriously founded by Him, He willed to perpetuate the mission which He had Himself received from the Father; and on the one hand, having put within her all the means necessary for man's salvation, on the other hand, He formally enjoined upon men the duty of obeying His Church as Himself, and religiously taking her as a guide of their whole lives. "He that heareth you, heareth Me; he that despiseth you, despiseth me." (Luke 10:16) Therefore, it is from the Church alone that the law of Christ must be asked: and, consequently, if for man Christ is the way, the Church, too, is the way, the former of Himself and by His nature, the latter by delegation and communication of power. Consequently, all who wish to reach salvation outside the Church, are mistaken as to the way and are engaged in a vain effort." (Pope Leo XIII, Encyclical, Tametsi, November 1, 1900; Papal Teachings: The Church, Benedictine Monks of Solesmes, St. Paul Editions, Boston, 1962, par. 647.)

"This is our last lesson to you: receive it, engrave it in your minds, all of you: by God's commandment salvation is to be found nowhere but in the Church; the strong and effective instrument of salvation is none other than the Roman Pontificate." (Pope Leo XIII, Allocution for the 25th anniversary of his election, February 20, 1903; Papal Teachings: The Church, Benedictine Monks of Solesmes, St. Paul Editions, Boston, 1962, par. 653.Encyclical, Annum Ingressi Sumus)

"He scatters and gathers not who gathers not with the Church and with Jesus Christ, and all who fight not jointly with Him and with the Church are in very truth contending against God." (Pope Leo XIII, Encyclical, Sapientiae Christianae)

"Strong in this faith, unshakably established on this Peter, We turn the eyes of Our soul both to the heavy obligations of this holy primacy and at the same time to the strength divinely imparted to Our heart. In peace We wait for those to be silent who are loudly proclaiming that the Catholic Church has had her day, that her teaching is hopelessly reactionary, that she will soon be reduced either to conformity with the data of science and a civilization without God, or to withdrawal from the society of men. And while We wait, it is Our duty to recall to everyone, great and small, as the Holy Pontiff Gregory did in ages past, the absolute necessity which is ours to have recourse to this Church to effect our eternal salvation, to obtain peace, and even prosperity in our life here below. "That is why, to use the words of the Holy Pontiff, we say: "Make firm the progress of your souls, as you have begun to do, with the firmness of this rock: on it, as you know, Our Redeemer founded the Church throughout the world, so that sincere hearts, guiding their steps by her, would not stray on to the wrong road." (Pope St. Pius X, Encyclical, Jucunda sane, March 12, 1904, Papal Teachings: The Church, Benedictine Monks of Solesmes, St. Paul Editions, Boston, 1962, par. 668.)

"Furthermore, in this one Church of Christ no man can be or remain who does not accept, recognize and obey the authority and supremacy of Peter and his legitimate successors. Did not the ancestors of those who are now entangled in the errors of Photius and the reformers, obey the Bishop of Rome, the chief shepherd of souls? Alas their children left the home of their fathers, but it did not fall to the ground and perish for ever, for it was supported by God. Let them therefore return to their common Father, who, forgetting the insults previously heaped on the Apostolic See, will receive them in the most loving fashion. For if, as they continually state, they long to be united with Us and ours, why do they not hasten to enter the Church, 'the Mother and mistress of all Christ's faithful?' Let them hear Lactantius crying out: 'The Catholic Church is alone in keeping the true worship. This is the fount of truth, this is the house of Faith, this is the temple of God: if any man enter not here, or if any man go forth from it, he is a stranger to the hope of life and salvation. Let none delude himself with obstinate wrangling. For life and salvation are here concerned, which will be lost and entirely destroyed, unless their interests are carefully and assiduously kept in mind.'" (Pope Pius XI, Encyclical, Mortalium animos, January 6, 1928, The Papal Encyclicals, Claudia Carlen, I.H.M., McGrath Publishing Co., 1981, pp. 317, 318.)

"Nor against this may one argue that the primacy of jurisdiction established in the Church gives such a Mystical Body two heads. For Peter in virtue of his primacy is only Christ's Vicar; so that there is only one chief Head of this Body, namely Christ, Who never ceases Himself to guide the Church invisible, though at the same time He rules it visibly, through him who is His representative on earth, after His glorious Ascension into heaven this Church rested not on Him alone, but on Peter too, its visible foundation stone. That Christ and His Vicar constitute one only Head is the solemn teaching of Our predecessor of immortal memory Boniface VIII in the Apostolic Letter Unam Sanctam; and his successors have never ceased to repeat the same. "They, therefore, walk in the path of dangerous errors who believe that they can accept Christ as the head of the Church, while not adhering loyally to His Vicar on earth. They have taken away the visible bonds of unity and left the Mystical Body of the Redeemer so obscured and so maimed, that those who are seeking the haven of eternal salvation can neither see it nor find it." (Pope Pius XII, encyclical Mystici Corporis which appeared in 1943; The Papal Encyclicals 1939-1958, Claudia Carlen, I.H.M., McGrath Publishing Co., 1981, p. 45.)

"By divine mandate the interpreter and guardian of the Scriptures, and the depository of Sacred Tradition living within her, the Church alone is the entrance to salvation: She alone, by herself, and under the protection and guidance of the Holy Spirit, is the source of truth." (Pope Pius XII, Allocution to the Gregorian, October 17, 1953)

"O Mary Mother of Mercy and Refuge of Sinners! We beseech thee to look with pitying eyes on poor heretics and schismatics. Do thou, who art the Seat of Wisdom, enlighten the minds wretchedly enfolded in the darkness of ignorance and sin, that they may clearly recognize the Holy, Catholic, Roman Church to be the only true Church of Jesus Christ, outside of which neither sanctity nor salvation can be found. Call them to the unity of the one fold, granting them the grace to believe every truth of our holy faith and to submit themselves to the Supreme Roman Pontiff, the Vicar of Jesus Christ on earth, that, thus being united with us by the sweet chains of charity, there may soon be but one fold under one and the same Shepherd; and may we all thus, O Glorious Virgin, exultantly sing forever: 'Rejoice, O Virgin Mary! Thou alone hast destroyed all heresies in the whole world!' Amen." (Pope Pius XII, The Raccolta, Benzinger Brothers, Boston, 1957, No. 626.)

"It is not possible to worship God truly except in Her; all who are outside Her will not be saved." (Encyclical, Summo Jugiter)

"Such is the nature of the Catholic faith that it does not admit of more or less, but must be held as a whole, or as a whole rejected: This is the Catholic faith, which unless a man believe faithfully and firmly, he cannot be saved." (Encyclical, Ad Beatissimi Apostolorum)

"The Saviour Himself is the door of the sheepfold: 'I am the door of the sheep.' Into this fold of Jesus Christ, no man may enter unless he be led by the Sovereign Pontiff; and only if they be united to him can men be saved, for the Roman Pontiff is the Vicar of Christ and His personal representative on earth." (Pope John XXIII, homily to the Bishops assisting at his coronation on November 4, 1958Papal Teachings: The Church, Benedictine Monks of Solesmes, Boston, St. Paul Editions, 1962, par. 1556.)

"And you, venerable brothers, will not fail, in your teaching, to recall to the flocks entrusted to you these grand and salutary truths; we cannot render to God the devotion that is due Him and that is pleasing to Him nor is it possible to be united to Him except through Jesus Christ; and it is not possible to be united to Jesus Christ except in the Church and through the Church, His Mystical Body, and, finally, it is not possible to belong to the Church except through the bishops, successors of the Apostles, united to the Supreme Pastor, the successor of Peter." (Pope John XXIII, Address on the creation of three new dioceses on Taiwan, L'Osseratore Romano, June 29, 1961.)

"According to the words of St. Augustine, who takes up an image dear to the ancient Fathers, the ship of the Church must not fear, because it is guided by Christ and by His Vicar. 'Although the ship is tossed about, it is still a ship. It alone carries the disciples and receives Christ. Yes, it is tossed on the sea, but, without it, one would immediately perish." (Sermon, 75,3; PL 28, 475) Only in the Church is salvation. 'Without it one perishes.' (Pope John Paul I, First Allocution, August 27, 1978, L'Osservatore Romano, August 28,29, 1978.)

"It is difficult to accept some truths, because the truths of faith are of two kinds: some pleasant, others unpalatable to our spirit. For example, it is pleasant to hear that God has so much tenderness for us, even more tenderness than a mother for her children. Other truths, on the contrary, are hard to accept. God must punish if I resist. That is not agreeable, but it is clear that Jesus and the Church are the same thing: indissoluble, inseparable. Christ and the Church are only one thing. It is not possible to say: 'I believe in Jesus, I accept Jesus, but I do not accept the Church.' When the poor Pope, when the bishops, the priests, propose the doctrine, they are merely helping Christ. It is not our doctrine; it is Christ's: we must merely guard it and present it." (General Audience, September 13, 1978; Quoted in The Message of John Paul I, Daughters of St. Paul, Boston, 1978, pp. 106,107.)

"The mystery of salvation is revealed to us and is continued and accomplished in the Church...and from this genuine and single source, like 'humble, useful, precious and chaste' water, it reaches the whole world. Dear young people and members of the faithful, like Brother Francis we have to be conscious and absorb this fundamental and revealed truth, consecrated by tradition: 'There is no salvation outside the Church.' From her alone there flows surely and fully the life-giving force destined in Christ and in His Spirit, to renew the whole of humanity, and therefore directing every human being to become a part of the Mystical Body of Christ." (Pope John Paul II, Radio Message for Franciscan Vigil in St. Peter's and Assisi, October 3, 1981, L'Osservatore Romano, October 12, 1981.)

"The holy Roman Church believes, professes, and preaches that no one remaining outside the Catholic Church, not just pagans, but also Jews or heretics or schismatics, can become partakers of eternal life; but they will go to the 'everlasting fire which was prepared for the devil and his angels' (Matt. 25:41), unless before the end of life they are joined to the Church. For the union with the body of the Church is of such importance that the sacraments of the Church are helpful to salvation only for those remaining in it; and fasts, almsgiving, other works of piety, and the exercise of Christian warfare bear eternal rewards for them alone. And no one can be saved, no matter how much alms he has given, even if he sheds his blood for the name of Christ, unless he remains in the bosom and unity of the Catholic Church." (Pope Eugene IV, Council of Florence, 1438-45, From the Bull "Cantate Domino", February 4, 1441 (Florentine style) Decree for the Jacobites, Denz. 165.)

"But as for you and your companions, you certainly sin, if, having heard the decrees of the Apostolic See, and of the universal Church, and the same is confirmed by Holy Writ, you refuse to follow them; for, though your fathers were holy, do you think that their small number, in a corner of the remotest island, is to be preferred before the universal Church of Christ throughout the world? And if that Columba of yours (and, I may say, ours also, if he was Christ's servant), was a holy man and powerful in miracles, yet could he be preferred before the most blessed prince of the Apostles to whom Our Lord said 'Thou art Peter, and upon this rock I will build my Church, and the gates of hell shall not prevail against it, and to thee I will give the keys of the kingdom of heaven'?" When Wilfrid had spoken thus, the king said, "Is it true Colman, that these words were spoken to Peter by Our Lord?" He answered, "It is true, O king!" Then says he, "Can you show any such power given to your Columba?" Colman answered, "None." Then added the king, "Do you both agree that these words were principally directed to Peter, and that the keys of heaven were given to him by Our Lord?" They both answered. "We do." Then the king concluded, "And I also say unto you, that he is the door-keeper, whom I will not contradict, but will, as far as I know and am able, in all things obey his decrees, lest, when I come to the gates of the kingdom of heaven, there should be none to open them, he being my adversary who is proved to have the keys." (St. Bede, Ecclesiastical History of the English Nation, quoted in Readings from Church History, Volume I, edited by Fr. Colman Barry, O.S.B., The Newman Press, Westminster, MD, 1966, p. 273.)

"It is shown also that it is necessary for salvation to be subject to the Roman Pontiff." (Opuscula Theologica, Vol. I, Part 2, Chap. 36, Edited by Fr. Raymond A. Verardo, O.P., Marietta, Turin, 1954, p. 344.)

"Jesus lives undiminished only in that Church which has written and preached the Scriptures; in that Church which celebrates the sacraments, proclaims the creeds, assembles the councils, worships the Father, offers the Body of the Lord in her liturgy, and lives by the unfailing Spirit of God. The Church is alive in Christ and Christ lives in His Church. Thus, she exists for the glory of God and the healing of mankind. In Christ she realizes how mighty is God's glory which abides with us in so tangible a manner. God, however, is not glorified nor are human hearts healed when men seek Christ while consciously rejecting His Church. Man is not allowed to pick and choose when he seeks God's will for himself." (The Church in Our Day," January 11, 1968, 1969 Catholic Almanac.)

Fr. Thomas R. Ryan, C.S.S.P. said of this Collective Pastoral letter later: "The American bishops in their Collective Pastoral Letter of 1969 said: 'Outside of Christ there is no salvation...Outside the Church no salvation.'" (Fr. Thomas R. Ryan, C.S.S.P., Orestes A. Brownson: A Definitive Biography, Our Sunday Visitor, Huntington, IN, 1978, p. 798, n. 31.)
