Not true. There is a very specific formula that is to be used to denote an article of faith that must be believed. None of the V2 documents invoke infallibility.
I disagree. As far as I know, the Church has not published any special formula that it uses to invoke infallibility. If they have, can you refer me to it? The Church has also never published a list of what is or is not infallible. I have never seen any Church document that said that Vatican II lacked the same authority as other Ecumenical Councils or any Church document that says that nothing in the Vatican II documents is infallible, or that Vatican II’s teachings are not binding. Besides, even the “non-infallible” parts of the Church’s teaching are to be believed by Catholics, and surely you would agree that the Dogmatic Constitution and the Catechism are the teachings of the Church?
Sure, a classic example is in LG speaking of the church:
This Church constituted and organized in the world as a society, subsists in the Catholic Church, which is governed by the successor of Peter and by the Bishops in communion with him, although many elements of sanctification and of truth are found outside of its visible structure.
What does “subsists in” mean? The Church has always taught that the Church of Christ is the Catholic Church. “IS” is much easier to understand and very precise. It denotes equality. But this choice to be imprecise has led to the new belief that the boundary of Church of Christ is larger than the Catholic Church and contains “others” and that, by this wording, The Church of Christ and The Catholic Church are different entities that intersect but not exclusive to each other. . And that in turn has led to the belief that it is not important/required for Protestants to convert to Catholicism for their salvation - nor necessarily Jews or other non-Christians, as long as they have some element of faith in (a) God and are nice. Which has in turn led to a de-emphasis of missionary conversion efforts abroad, IMHO
I have seen this referenced as vague or imprecise or meaningless by others. I don’t disagree that this could be explained better, and maybe with different or fewer words, but I don’t think that the passage is imprecise. Even if it might be, the same principles are well explained in the Catechism in CCC 813-822.
My Websters defines “subsists” as “to exist,” “to remain in existence,” and notes that it derives from the Latin for “to stand up.” I agree that “subsists” is not a common word, and perhaps not the word that speakers of American English would have chosen. But other than one uncommon word, which anyone can look up, the passage is not difficult.
The real problem is not that this passage is hard to understand, it is that some people don’t like what it says.
This section of Lumen Gentium is discussing the Body of Christ and the relationship between Christ and His Church. The previous paragraph says that the Mysterious Body of Christ is not seperate from the earthly Church structure, that the visible assembly of the Church on earth and the spiritual Church are each aspects of the one Church, earthly and divine.
Up to this point, the document has described the Church, its origin, etc., but never explicitly said that the Church is the Catholic Church. Lumen Gentium then says that the Church, refering to the earthly and divine Church founded by Christ and discussed in the previous sentence and previous paragraph, subsists, that is exists and remains in existence, in the Catholic Church. What is difficult about that?
The problem is not really with the word subsists, the problem is that some are troubled by the next clause, which says that “many elements of sanctification and of truth are found outside of its visible structure.” It is said that the Church has not explained this well, but the Catechism explains it, although using more words than I am allowed here. The short of it is that it is through the Catholic Church alone that the fullness of the means to salvation can be obtained, but there are elements of truth to be found in other faiths. This is not due to chance; the Spirit acts on all men, just as Christ died for all men. Christ is not bound within the Church. His Grace is offered to all men, and some men are inspired to reach toward the Truth even without the aid of formal acceptance into the earthly Church.
Yes, as taught more explicitly elsewhere, this is related to the Church’s teaching that it is possible for non-Catholics and even non-Christians to be saved. But the Church has repeatedly emphasized, including in the documents of Vatican II, that this doctrine does not mean that it is not important to bring the Gospel to all men or that it is not important to continue to work to bring seperated Christians back to full communion with the Church, because “it is through Christ’s Catholic Church alone, which is the universal help toward salvation, that the fullness of the means of salvation can be obtained.” CCC 816 quoting Vatican II’s Decree on Ecumenism.
