Cardinal Müller vs. the SSPX: Did Vatican II Break with Tradition?

In his recent interview with Communio, Cardinal Gerhard Müller criticized the Society of St. Pius X (SSPX) for, among other things, its questioning of certain documents from Vatican II. The thrust of Cardinal Müller’s argument was based on the hermeneutic of continuity, according to which the Council’s documents are perfectly orthodox when “read in the context of the Church’s entire tradition”:

“When the statements of the Second Vatican Council – which the Society of St. Pius X criticises – are read in the context of the Church’s entire tradition, a relativist interpretation becomes untenable. This applies equally to so-called progressives, who reduce revelation to general religious history and deny its supernatural character and the uniqueness of Christ as the Saviour of the world. Nor, with regard to ecumenism with non-Catholic Christians, Christian communities, and the Orthodox Churches, did the Council in any way call into question the necessity of the Catholic Church for salvation or its full identity with the Church of the Apostles.”

Because Cardinal Müller specifically identified “ecumenism with non-Catholic Christians” as an area of Vatican II in which there is perfect continuity with what the Church has always taught, it is worthwhile to examine the Church’s pre-Vatican II teachings and the common ways in which people have interpreted the applicable provisions from the Council. In this way, we can better understand Cardinal Müller’s position that the Council did not “in any way call into question the necessity of the Catholic Church for salvation.”

What the Church Has Always Taught

As discussed in a previous article, we can find a comprehensive statement of the Church’s immutable teaching from Pius IX’s 1854 allocution, Singulari Quadam:

“Certainly we must hold it as of faith that no one can be saved outside the apostolic Roman Church, that this is the only Ark of salvation, and that the one who does not enter it is going to perish in the deluge. But, nevertheless, we must likewise hold it as certain that those who labor in ignorance of the true religion, if that [ignorance] be invincible, will never be charged with any guilt on this account before the eyes of the Lord. Now, who is there who would arrogate to himself the power to indicate the extent of such [invincible] ignorance according to the nature and the variety of peoples, regions, talents, and so many other things? For really when, loosed from these bodily bonds, we see God as He is, we shall certainly understand with what intimate and beautiful a connection the divine mercy and justice are joined together. But, while we live on earth, weighed down by this mortal body that darkens the mind, let us hold most firmly, from Catholic doctrine, that there is one God, one faith, one baptism. It is wrong to push our inquiries further than this.” (quoted in Msgr. Joseph Clifford Fenton’s The Catholic Church and Salvation, p. 43)

In his commentary on this passage from Singulari Quadam, Msgr. Joseph Clifford Fenton emphasized the following crucial point related to invincible ignorance:

“Some translations tend to present invincible ignorance of the true religion as a sort of sacrament, since they make it appear that the Sovereign Pontiff taught that persons invincibly ignorant of the true religion are simply not blameworthy in the eyes of the Lord. The fact of the matter is (and this is the gist of the teaching of Pope Pius IX here and in the encyclical Quanto conficiamur moerore) that non-appurtenance to the Catholic Church is by no means the only reason why men are deprived of the Beatific Vision. Ultimately, the only factor that will exclude a man from eternal and supernatural enjoyment of God in heaven is sin, either original or mortal. An infant who dies without having been baptized will not have the Beatific Vision because original sin has rendered him incapable of it. Any man who dies after having attained the use of reason and who is eternally excluded from the Beatific Vision is being punished for actual mortal sin which he has committed.” (The Catholic Church and Salvation, pp. 45-46)

Based on the words of both Pius IX and Msgr. Fenton, we can understand why the Catholic Church must always do all it can to lead souls to the Catholic Faith. If, in His infinite mercy, God deigns to save those who are ignorant of the Catholic Church and yet otherwise free from mortal sin, that is entirely a matter of God’s Providence. For those of us who are not God, though, the Catholic Church has been charged with teaching all souls that they should be Catholic.

Related to this essential consideration, Msgr. Fenton stressed that Singulari quadam opposes the notion that other Christian religions are simply less-good alternatives to the true Catholic Faith:

“In this section of the Singulari quadam, Pope Pius IX goes on to urge the Bishops of the Catholic Church to use all of their energies to drive from the minds of men the deadly error that the way of salvation can be found in any religion. To a certain extent, this is a mere restatement of the erroneous opinion according to which we may well hope for the salvation of men who have never entered into the Catholic Church, the first misinterpretation of Catholic teaching reproved in this section of the allocution. Yet, in another way, the error that the way of salvation can be found in any religion has its own peculiar and individual malignity. It is based on the false implication that the false religions, those other than the Catholic, are in some measure a partial approach to the fullness of truth which is to be found in Catholicism. According to this doctrinal aberration, the Catholic religion would be distinct from others, not as the true is distinguished from the false, but only as the plentitude is distinct from incomplete participations of itself. It is this notion, the idea that all other religions contain enough of the essence of that completeness, of truth which is to be found in Catholicism, to make them vehicles of eternal salvation, which is thus reproved in the Singulari quadam.” (The Catholic Church and Salvation, p. 47)

Evidently, Pius IX and Msgr. Fenton were both aware of the fact that false shepherds were spreading the deadly errors related to the necessity of the Catholic Church for salvation. Because of the supreme importance of ensuring that the Catholic Church never teaches anything that remotely calls into question the truths explained above by Pius IX and Msgr. Fenton, it would be truly wicked for any purported Catholic to in any way diminish or confuse these truths. With this in mind, we can now consider the key passage from the Council’s decree on ecumenism, Unitatis Redintegratio.

What Vatican II Taught in Unitatis Redintegratio

“The differences that exist in varying degrees between [non-Catholic communities] and the Catholic Church — whether in doctrine and sometimes in discipline, or concerning the structure of the Church — do indeed create many obstacles, sometimes serious ones, to full ecclesiastical communion. The ecumenical movement is striving to overcome these obstacles. But even in spite of them, it remains true that all who have been justified by faith in Baptism are members of Christ’s body, and have a right to be called Christian, and so are correctly accepted as brothers by the children of the Catholic Church. Moreover, some and even very many of the significant elements and endowments which together go to build up and give life to the Church itself can exist outside the visible boundaries of the Catholic Church: the written word of God; the life of grace; faith, hope, and charity, with the other interior gifts of the Holy Spirit, and visible elements too. All of these, which come from Christ and lead back to Christ, belong by right to the one Church of Christ. The brethren divided from us also use many liturgical actions of the Christian religion. These most certainly can truly engender a life of grace in ways that vary according to the condition of each Church or Community. These liturgical actions must be regarded as capable of giving access to the community of salvation. It follows that the separated Churches and Communities as such, though we believe them to be deficient in some respects, have been by no means deprived of significance and importance in the mystery of salvation. For the Spirit of Christ has not refrained from using them as means of salvation which derive their efficacy from the very fullness of grace and truth entrusted to the Church. Nevertheless, our separated brethren, whether considered as individuals or as communities and churches, are not blessed with that unity which Jesus Christ wished to bestow on all those who through Him were born again into one body, and with Him quickened to newness of life—that unity which the Holy Scriptures and the ancient tradition of the Church proclaim. For it is only through Christ’s Catholic Church, which is ‘the all-embracing means of salvation,’ that they can benefit fully from the means of salvation.”

Cardinal Müller’s argument is that we must read this as meaning the exact same thing as the Church has always taught, which is reflected in what Pius IX and Msgr. Fenton wrote. Thus, according to Cardinal Müller, an entirely proper response to anyone asking what Unitatis Redintegratio said about non-Catholic religions would be to simply produce the same statements from Pius IX and Msgr. Fenton quoted above.

Nonetheless . . . it is of interest to consider how some people have “mistakenly” interpreted Unitatis Redintegratio as having a somewhat different meaning than what Pius IX wrote in Singulari quadam.

Some Interpretations of Unitatis Redintegratio

As detailed in an article from the SSPX, “on April 5, 2012, Polish intellectuals sent to the Holy Father a new petition for a re-examination of the religious liberty, ecumenism, and collegiality promoted by Vatican II.” Among the statements in the petition was the following related to the passage above from Unitatis Redintegratio and a similar passage from Lumen Gentium:

“The many elements of ‘sanctification’ and ‘truth’ present outside the limits of the Church are also mentioned in the Dogmatic Constitution Lumen Gentium, in paragraph 8. How else could the expression ‘can aptly give access to the communion of salvation’ be understood, if not as an assurance that persons are capable of attaining salvation outside the Catholic Church, thanks to rituals and practices of other Christian denominations? However, the question that arises is how this interpretation can be reconciled with the traditional doctrine, Extra Ecclesiam nulla salus, [‘No salvation outside the Church,’] which declares that the Catholic faith is a prerequisite for salvation, or with the teaching about the unity of the Church established, in particular, by Leo XIII: ‘And to set forth more clearly the unity of the Church, he [St. Cyprian] makes use of the illustration of a living body, the members of which cannot possibly live unless united to the head and drawing from it their vital force. Separated from the head, they must of necessity die. . . . The Church of Christ, therefore, is one and the same for ever; those who leave it depart from the will and command of Christ, the Lord—leaving the path of salvation, they enter on that of perdition.’ What is the relation between these statements from Unitatis Redintegratio and the condemned propositions 16 and 17 from the Syllabus of Pius IX?”

The Polish intellectuals in question had interpreted Vatican II’s statement that God makes use of non-Catholic religions as means of salvation as meaning that non-Catholic religions can be vehicles for salvation. Some learned defenders of Vatican II may characterize this as absurd, but one can understand how ordinary Catholics could reach that conclusion.

We can also consider a passage from another document, this one from the Vatican’s official website. Eleuterio F. Fortino’s essay — The Holy Spirit’s Presence Among Other Christians — had this to say about the passage in question from Unitatis Redintegratio:

“The Holy Spirit’s presence is not limited to individual Christians, but he is at work in other Churches and ecclesial communities as such. In fact, these communities carry out ‘many liturgical actions of the Christian religion (. . .) these can truly engender a life of grace, and, one must say, can aptly give access to the communion of salvation.’ This is the reason that justifies and gives content to the short conciliar declaration according to which ‘the Spirit of Christ has not refrained from using them — other Churches and ecclesial communities — as means of salvation.’ . . . Other Churches and ecclesial communities have proclaimed — and continue to proclaim — the Gospel. They have founded missionary communities, they have supported welfare services for the poor and suffered for the justice and peace demanded by the Lord’s teaching.”

This essay from the Vatican’s website points to the language from Unitatis Redintegratio to unambiguously assert that non-Catholic religions are means of salvation. Thus, unless this essay from the Vatican website is simply wrong — in which case, perhaps it should not be on the Vatican website — it seems that it is possible to interpret Unitatis Redintegratio as meaning essentially what the Polish intellectuals thought it meant.

Finally, we can consider a question and response from a 2007 document from the Congregation for the Doctrine of the Faith, which cites Lumen Gentium and Unitatis Redintegratio to explain the term “subsists in”:

“THIRD QUESTION Why was the expression ‘subsists in’ adopted instead of the simple word ‘is’? RESPONSE The use of this expression, which indicates the full identity of the Church of Christ with the Catholic Church, does not change the doctrine on the Church. Rather, it comes from and brings out more clearly the fact that there are ‘numerous elements of sanctification and of truth’ which are found outside her structure, but which ‘as gifts properly belonging to the Church of Christ, impel towards Catholic Unity.’ ‘It follows that these separated churches and Communities, though we believe they suffer from defects, are deprived neither of significance nor importance in the mystery of salvation. In fact the Spirit of Christ has not refrained from using them as instruments of salvation, whose value derives from that fullness of grace and of truth which has been entrusted to the Catholic Church.’”

The meaning of this is that whereas the Catholic Church is the only church that is “fully identified” with the Church of Christ, the non-Catholic religions are also vehicles of salvation, albeit with some defects.

Each of these three interpretations appears to conflict with the words above from Msgr. Fenton:

“It is this notion, the idea that all other religions contain enough of the essence of that completeness, of truth which is to be found in Catholicism, to make them vehicles of eternal salvation, which is thus reproved in the Singulari quadam.”

If Pius IX condemned the idea that non-Catholic religions are vehicles of salvation, how can we say that Unitatis Redintegratio preserved the Catholic teaching intact by saying the opposite?

Making Sense of the Opposing Viewpoints

There are loud voices on each side of this debate. The principle of non-contradiction tells us that they cannot all be right: it is possible for all to be wrong, but only one can be correct. Here are a few context clues to help us discern who is correct:

The defenders of Vatican II do not like these questions but have ready answers to them, generally involving a potent mix of hostility and sophistry. The answers from Vatican II’s defenders generally contradict not only the SSPX, but also the beliefs of all of the pre-Vatican II popes who spoke on these matters. They demand that we affirm that nothing changed and also that everything changed.

But if we are truly seeking the way to make sense of the opposing viewpoints, we can look to one particular idea from Cardinal Müller’s interview:

“The SSPX considered its objections to religious freedom, ecumenism, and the relationship of the Church to other religions – as set out in the relevant conciliar documents – as the very measure of Catholicism, and demanded that the Church – with all its bishops and the Pope as the Successor of Peter – admit that the Council had presented false and ambiguous teachings and that the highest doctrinal authority had erred in matters of faith and morals and thus intentionally or negligently deceived the faithful and endangered their salvation. To admit this would not only be wrong in terms of content but also the hermeneutical self-destruction of the ‘Church as the pillar and foundation of truth’ (1 Tim 3:15).”

The idea is that to admit that there are problems with the Council would destroy the Church. Because we do not want to destroy the Church, Cardinal Müller argues, we cannot admit that there are any contradictions between the language of the Council and what the Church has always taught. Anyone who disagrees is to be silenced by whatever means necessary.

For those who may not be entirely satisfied with this line of (suppression of) thinking, here is the SSPX response:

“Contrary to Cardinal Müller’s assertion, the arguments put forward by the Society are not ‘fallacious arguments intended to avoid fully submitting to the Pope’s authority.’ For there is indeed a contradiction, a rupture if you will, between the teachings of Vatican II on the points raised and the constant Tradition of the Magisterium of the Church. To this evidence imposed upon us by the principle of non-contradiction, what is the response of the Prefect Emeritus of the Congregation for the Doctrine of the Faith? ‘To admit this would not only be fundamentally erroneous, but would also constitute the hermeneutical self-destruction of the Church, the pillar and foundation of truth (1 Tim. 3:15).’ Should we then admit that the Tradition of the Church is reduced to the Second Vatican Council alone, and that the Church itself is reduced to the post-Conciliar Popes? . . . We could thus endlessly hurl the accusation of autocephaly—or schism—at each other. But the criterion of true communion, that of the unity and apostolicity of the Church, is not that of the majority: the smallest group is not necessarily the schismatic stronghold. This criterion was given to us by Saint Vincent of Lérins: it is the criterion of the constancy and universality of the profession of faith throughout time. And this positive criterion is itself coupled with a negative one: that which currently contradicts the explicit profession of faith of the Church cannot represent the principle of unity and apostolicity. Now, on all the points raised, the documents of the Council cited by the Cardinal represent and express this contradiction. It is therefore not the Fraternity that is moving away from the unity of the Church by refusing to admit these points of doctrine, but rather all those who want to impose them against the constant Tradition of the Catholic Magisterium.”

The debate about the SSPX has very little to do with the consecration of bishops and almost everything to do with the SSPX’s stubborn refusal to abandon what the Church has always taught. This is a dangerous idea in the eyes of those who seek to suppress Catholic tradition, one that must be opposed at all costs. Most of us have chosen sides already, but for those still undecided, it is worth considering whether we agree with St. Vincent of Lérins or with those who have been overseeing the mass apostasy that has transformed hundreds of millions of nominal Catholics into Protestants who happen to believe in the pope. Immaculate Heart of Mary, pray for us!

In some ways, it's a trick question. VII was left deliberately vague, but even still, most of the steps take in the name of VII, were not called for, or explicitly against the text of VII.

Take the Novus Ordo Mass. The creation of the Mass was only started a few years after VII, but they completely dumped it's document on liturgy and created something altogether different. The 1962 Missal is far closer to what VII called for then what we have.

The 1962 Missal was still the Tridentine Mass.

Maybe you meant the 1967 Missal?

Here's a question for you.

If the argument of the SSPX is the following:
1. A state of emergency exists in the Church.
2. This state of emergency is not the traditional state of emergency where a bishop is in a remote area or where communication with Rome is difficult or too time-consuming to have contact prior to the consecration of a bishop. (Communication with Rome is open and easily accessible.)

What is the difference between this current SSPX "state of emergency" and outright heresy?

(Why couldn't any bishop do whatever he wanted and simply say, "state of emergency" when questioned on it?)

Here's a better question for you:

Why can any heretic bishop do whatever he wants (give Holy Communion to adulterers and pro-abort politicians, bless homosexual unions, advocate for women priests, etc.) and go unsanctioned in today's Synodal Church?

What exactly does the Captain think an "emergency" is?

Do agree with the removal of Bishop Strickland as bishop of Tyler, Texas while heretic bishops like McElroy, Cupich, Tobin, and Gregory are all promoted to the college of cardinals?

I guess your OK with all that, Captain Bob.

Captain Baghdad Bob Walker

According to Traditionis Custodes, which is still in force, no newly ordained priests will by allowed to offer the TLM unless give papal approval (which appears to be highly unlikely).

Art. 4. Priests ordained after the publication of the present Motu Proprio, who wish to celebrate using the Missale Romanum of 1962, should submit a formal request to the diocesan Bishop who shall consult the Apostolic See before granting this authorization.

The Catholic Church needs good bishops who will ignore this draconian law and give us priests to continue offering the TLM.

But apparently, Captain Bob, feels otherwise.

This state of emergency is not the traditional state of emergency where a bishop is in a remote area or where communication with Rome is difficult

The SSPX requested an audience with Pope Leo, which was first accepted, but then denied, twice.

So there goes you defense of "communication with Rome is difficult".

Meanwhile, Pope Leo sends congratulations to a fake female "bishop" who was elected to head the Church of England and whom he plans to welcome to an audience this year.
