If you really want to be part of this conversation, you might want to define what you mean by “out” (with supporting documents" and what you mean by in"with supporting documents), since you seem to be implying that there has been a change in truth aobut them.
Before Vatican II
Pope Innocent III (A.D. 1198 - 1216): “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)
Pope Gregory XVI (A.D. 1831 - 1846): “It is not possible to worship God truly except in Her; all who are outside Her will not be saved.” (Encyclical, Summo Jugiter)
Pope Pius IX (A.D. 1846 - 1878): “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)
Pope Leo XIII (A.D. 1878 - 1903): “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.” (Encyclical, Annum Ingressi Sumus)
Pope Benedict XV (A.D. 1914 - 1922): “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)
Pope Pius XI (A.D. 1922 - 1939): “The Catholic Church alone is keeping the true worship. This is the font 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…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.” (Encyclical, Mortalium Animos)
Pope Pius XII (A.D. 1939 - 1958): “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.” (Allocution to the Gregorian, October 17, 1953)
Pope Innocent III and Lateran Council IV (A.D. 1215):
"One indeed is the universal Church of the faithful outside which no one at all is saved…"
Pope Boniface VIII in his Papal Bull Unam Sanctam (A.D. 1302):
"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 and the Council of Florence (A.D. 1438 - 1445): “[The most Holy Roman Church] firmly believes, professes, and proclaims that those not living within the Catholic Church,
not only pagans, but also Jews and heretics and schismatics cannot become participants in eternal life, but will depart `into everlasting fire which was prepared for the devil and his angels’ (Matt. 25:41), unless before the end of life the same have been added to the flock; and that the unity of the ecclesiastical body is so strong that only to those remaining in it are the sacraments of the Church of benefit for salvation, and do fastings, almsgiving, and other functions of piety and exercises of Christian service produce eternal reward, and that no one, whatever almsgiving he has practiced, even if he has shed blood for the name of Christ, can be saved, unless he has remained in the bosom and unity of the Catholic Church.”

**The Church and non-Christians **
839 "Those who have not yet received the Gospel are related to the People of God in various ways."325
The relationship of the Church with the Jewish People. When she delves into her own mystery, the Church, the People of God in the New Covenant, discovers her link with the Jewish People,326 "the first to hear the Word of God."327 The Jewish faith, unlike other non-Christian religions, is already a response to God’s revelation in the Old Covenant. To the Jews “belong the sonship, the glory, the covenants, the giving of the law, the worship, and the promises; to them belong the patriarchs, and of their race, according to the flesh, is the Christ”,328 "for the gifts and the call of God are irrevocable."329
840 And when one considers the future, God’s People of the Old Covenant and the new People of God tend towards similar goals: expectation of the coming (or the return) of the Messiah. But one awaits the return of the Messiah who died and rose from the dead and is recognized as Lord and Son of God; the other awaits the coming of a Messiah, whose features remain hidden till the end of time; and the latter waiting is accompanied by the drama of not knowing or of misunderstanding Christ Jesus.
841 The Church’s relationship with the Muslims. "The plan of salvation also includes those who acknowledge the Creator, in the first place amongst whom are the Muslims; these profess to hold the faith of Abraham, and together with us they adore the one, merciful God, mankind’s judge on the last day."330
