What an off-the-wall question, meant --- I see --- as a comparison. The Catholic Church does not teach that.
I'll say to you Cynical, what I said to metmom: why don't you do your due diligence of finding out if a thing is true before you say it?
The Catechism's online, you know.Searchable, with keywords.
Honestly, it's so easy.
Oh really?
“There is but one universal Church of the faithful, outside which no one at all is saved.” (Pope Innocent III, Fourth Lateran Council, 1215.)
“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 Boniface VIII, the Bull Unam Sanctam, 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.)
Pope Pelagius II (A.D. 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 246-247)
Pope Saint Gregory the Great (A.D. 590 – 604): “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)
Pope Leo XII (A.D. 1823 – 1829): “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)
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 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)
