What does it mean for Catholics to believe in ‘One’ Holy Catholic Apostolic Church?
This article is the first part of a three part series which will be published over the course of the next week.
April 8, 2021 (LifeSiteNews) – Every Sunday we profess belief in one holy catholic and apostolic Church. Many Catholics know that our Lord Jesus Christ founded one Church, rather than many, and that this is the Roman Catholic Church.[i] Indeed, this claim has driven many converts to enter her fold over the years. This is sometimes called the unicity (or ‘uniqueness’) of the Church, distinguishing it from her unity.
But unicity is not all it means for the Church to be one. In 1928, Pope Pius XI wrote his encyclical Mortalium animos against the twentieth-century ecumenical movement. This movement held that there was indeed only one visible Church, but that it was “composed of various communities of Christians, even though they adhere to different doctrines, which may even be incompatible one with another.”[ii]
Against this, Pius XI taught that the Catholic Church is ‘one’, not just in the sense that she is unique, but also in that she is united– and already enjoying the unity for which our Lord prayed when he said: “That they all may be one.... And there shall be one fold and one shepherd.” (John 17.21, 10.16) Rather than wishing for an unrealised ideal, our Lord’s prayer was the efficacious cause of a remarkable unity of faith and charity, which she continued to enjoy for centuries.[iii]
Given the division amongst those calling themselves Catholics today, it can seem hard to believe that this unity of faith was treated in apologetics as a fact which actually proved the Church’s claims. In other words, the truth of the Church’s claims was in part established by this visible unity of faith. But even if this seems strange now, it is the teaching of the Church: rather than dismiss it, we must try to understand what it means.
To consider this idea, we will turn to magisterial documents from before Vatican II, and a range of pre-conciliar (English-language) dogmatic theology and ecclesiology manuals. We have previously established why this is necessary elsewhere.[iv] In this article we will mainly refer to Father E. Sylvester Berry’s 1927 manual The Church of Christ, and establish our theses further with other texts in a subsequent article. Father Berry was the Professor of Apologetics at St Mary’s Seminary, Emmitsburg, Maryland. His manual is a respected and clear expression of standard ecclesiology.
This is a big topic, and we will be limiting ourselves just to what it means for the Church to be united in her external profession of the same faith.
One Lord, one faith, one baptism
Starting with the basics, the Penny Catechism states the following:
The Church is One because all her members agree in one Faith, all have the same Sacrifice and Sacraments, and all are united under one Head.[v]
The same doctrine is expressed in the fairly recent Baltimore Catechism and the Catechism of St Pius X. It is a part of a beautiful tapestry of other truths, corresponding to the words of St Paul: “One Lord, one Faith, one Baptism.” (Eph 4.5.) It also corresponds to Pius XII’s definition of who is a member of the Church in Mystici Corporis Christi:
Actually only those are to be included as members of the Church who have been baptized and profess the true faith, and who have not been so unfortunate as to separate themselves from the unity of the Body, or been excluded by legitimate authority for grave faults committed.[vi]
Even before Pius XII, the First Vatican Council made several beautiful points on this idea, including:
The eternal shepherd and guardian of our souls, in order to render permanent the saving work of redemption,determined to build a Church in which, as in the house of the living God, all the faithful should be linked by the bond of one faith and charity.[ix]
We can see that there are different unities here, but what does it mean for the Church to enjoy unity of faith? How did the Church and her theologians understand this idea?
Unity of profession
According to Berry, the general concept of supernatural faith entails:
A doctrine taught (‘objective faith’);
Its internal acceptance by those who are taught it (‘subjective/internal faith’); and
Its external profession of the internal faith.[x] This is the main focus of this article.
What does the Church teach about this external profession of faith? Vatican I taught that:
So that we could fulfil our duty of embracing the true faith and of persevering unwaveringly in it, God, through his only begotten Son, founded the Church, and he endowed his institution with clear notes to the end that she might be recognised by all as the guardian and teacher of the revealed word. […]
The Church herself, by reason of […] her catholic unity and her unconquerable stability is a kind of great and perpetual motive of credibility and an incontrovertible evidence of her own divine mission.[xi]
In other words, the Church taught that she has ‘clear notes’, proving her claims: and that one of these is unity. This remarkable unity in the Church is itself a proof of her divine mission. As explained in Session IV of Vatican I, this unity is specifically in faith and charity. This sense was explained by theologians in the following decades. Consider again Father Berry:
Unity in the profession of faith is a natural consequence of the unity of doctrine; a mere corollary to be explained rather than proved.[xii]
Even as a ‘natural consequence’, this external unity of faith was seen as an evident, astonishing fact.[xiii] Elsewhere, Berry continues:
He who rejects the very principles of a society by word or act, thereby rejects the society itself and ceases to be a member. Therefore, every member of the Church [must] make at least an outward profession of faith. […] Since this outward profession concerns the one faith taught by the Church, it will be essentially the same for all its members; in other words, there will be unity in the outward profession of faith.[xiv]
The content of this profession
What is the content of this faith? “The one faith taught by the Church”, says Berry. It is not merely “an acceptance of Christ as Saviour, with confidence in his merits and will to save.”[xv] It is not just a set of ‘fundamental doctrines’ upon which all who claim to be Christian could agree (e.g., just things like the Trinity, or the Resurrection). It is not just those things solemnly defined by a pope or a council. Instead, it is an adherence to the whole body of doctrine, as Berry says:
It is a well-known fact that the Church has always demanded the strictest unity in the profession of faith; those who refused to profess even a single doctrine, were condemned as heretics who had already ceased to be members. (99)
This is substantially the same idea given magisterial authority by Leo XIII in his encyclical Satis cognitum:
It was thus the duty of all who heard Jesus Christ, if they wished for eternal salvation, not merely to accept His doctrine as a whole, but to assent with their entire mind to all and every point of it, since it is unlawful to withhold faith from God even in regard to one single point. […]
Hence as the Apostles and Disciples were bound to obey Christ, so also those whom the Apostles taught were, by God's command, bound to obey them. And, therefore, it was no more allowable to repudiate one iota of the Apostles' teaching than it was to reject any point of the doctrine of Christ Himself. […]
The practice of the Church has always been the same, as is shown by the unanimous teaching of the Fathers, who were wont to hold as outside Catholic communion, and alien to the Church, whoever would recede in the least degree from any point of doctrine proposed by her authoritative Magisterium. (8-9)
There is no indication, not even in the word ‘authoritative’, that this is limited to the solemn definitions such as that of the Assumption or the Immaculate Conception. Leo XIII says, “One single point… one iota… in the least degree from any point”. Berry and others all take him at his word.
Submission to the magisterium
This unity of faith is based on two things: the content of the doctrine professed, which is caused by the readiness of the faithful to be submissive to the Church’s magisterium as their proximate rule of faith.[xvi]
We must avoid binary thinking here. The writers consider that the united profession of faith is not jeopardised by some being wrong or ignorant, so long as they continued to be submissive to the magisterium.[xvii]
But this is because what is important here is the submission itself – and not a mere claim to be submissive to the magisterium. The idea that the unity of the magisterium can be preserved by mere claims (some of which might be manifestly false) is crass and legalistic. This is not what the theologians meant.
Rather, if someone claims to be submissive to the magisterium, and yet is openly denying or doubting dogma and obviously knows what they are doing, their claim is vain. Consider this text from Cardinal Juan de Lugo (died 1660):
If it be certain by some other means – for example, if the doctrine in question be well known, or if it be obvious from the kind of person and other circumstances involved– that the accused person could not have been ignorant of the opposition of his doctrine to that of the Church, he will automatically be judged a heretic.[xviii]
It is simply obvious that those with greater learning have a lower burden of proof to establish their rebellion. We can certainly recognise some situations like this, such as when educated priests publicly deny dogmatic truths on social media platforms.
So there are cases where we can know that the necessary subjection is present; some where we can know that it is not present, and many where we cannot know, and so can mostly give the benefit of the doubt.
This is not about judging souls – it is just about recognising reality and being able to know who is and is not a Catholic. Indeed, individuals are not even primarily under discussion here, except as parts of the overall picture.
But regardless, when the Church and her theologians say that the unity of faith is a proof of the Church’s claims, they are referring to the wonderful, indisputable fact that Catholics in practice all believed the same things as each other, and as their ancestors and predecessors, and that they are docilely taught by that magisterium, even outside of its solemn extraordinary definitions. They not only all believe that our Lord became man, that there are three persons in one God, and so on: they also are habitually docile to (for example) the teaching of the encyclicals. This is why Pius XII could write in his encyclical Humani generis:
Nor must it be thought that what is expounded in Encyclical Letters does not of itself demand consent, since in writing such Letters the Popes do not exercise the supreme power of their Teaching Authority. For these matters are taught with the ordinary teaching authority, of which it is true to say: "He who heareth you, heareth me"; and generally what is expounded and inculcated in Encyclical Letters already for other reasons appertains to Catholic doctrine. But if the Supreme Pontiffs in their official documents purposely pass judgment on a matter up to that time under dispute, it is obvious that that matter, according to the mind and will of the Pontiffs, cannot be any longer considered a question open to discussion among theologians.[xix]
Note again that when he talks about popes passing judgements, Pius XII is explicitly not talking about “the supreme power of [the pope’s] Teaching Authority”.
Even granting exceptions for mistakes about the faith, and even for debates about some theological matters, it is this visibly united profession of faith, and not some unified but merely verbal submission to the magisterium, that so astonished Catholics and non-Catholics alike, and served as a mark of the Church. A merely verbal submission is not astonishing in itself. In fact, Salaverri could even teach that this unity of profession of faith is (like the Church’s other unities) “manifestly visible, easily recognizable and more known [to us] than the Church herself [is] recognized as true” – namely, there were more people who knew that the Roman Church was thus united, than who knew that she was the true Church.[xx] Which makes sense, “for otherwise it would not be a help to recognize the true Church.”[xxi]
All this shows that, without reading such pre-conciliar sources, we cannot truly appreciate how serious our current crisis is. Because this unity – which was taught to be a necessary part of the Church’s visible nature and proof of her claims – appears to have vanished today.
The current situation
Consider, for example, the recent events following the CDF’s document on the blessing of homosexual unions. Even without considering which side is right, it is evident that there is enormous disunity, supposedly “within the Catholic Church,” about some very basic issues.
Another poll of U.S. Catholics found that only 31% actually believed that “the bread and wine actually become the body and blood of Jesus.”[xxiii] By contrast, 69% believe that “the bread and wine used in Communion ‘are symbols of the body and blood of Jesus Christ.’” Of this latter group, most actually think that this is the Church’s teaching! But about one third of them said that they knew that they were rejecting the Church’s teaching.
In the same study, even 37% of weekly Mass-goers did not accept the Church’s teaching on transubstantiation.
We see here again, the three basic groups: those who believe the Catholic faith; those who believe something different but are probably or possibly submissive to the magisterium (and amongst the laity, can be given the benefit of the doubt); and those who knowingly reject both the content of the faith and the magisterium teaching it.
We can leave aside the question of whether privately answering a poll constitutes a public departure from the profession of faith – this is not important here. The important thing is that some of the people who consciously reject both the teaching and the authority will manifest this in a public way: and in fact, the practices of some parish Masses may already sufficiently manifest this.[xxiv] And yet all of these people continue to be considered as Catholics, as members of the Catholic Church.
Again, this is not judging souls, as individual cases are not the point. We are simply recognising that today, it appears that those who are called Catholics are not united in what they profess to believe. There is not even a pretence to profess these things.
This same phenomenon would surely apply to other dogmas if they were polled, and indeed at least one popular Catholic dating agency allows its users to select which of six certain dogmas they accept. Other users can even filter their searches by adherence or rejection to these dogmas. Does that create the impression of a visibly united organization?
Unity of doctrine or teaching
All this is to say nothing of the fact that in one parish one might hear the Catholic faith preached, and yet in another parish one might hear heresy from the pulpit. Incidentally, this reality is even clearer in the age of livestreamed services. Given his office and training, a priest certainly knows when he is refusing submission to the magisterium. And yet all of these parishes and preachers will be in good standing, in the same organization.
In fact, this disunity in preaching is itself not possible for the Church – and in some ways it is the cause of the disunity in belief and profession of the faith. As mentioned above, Berry teaches that the unity of doctrine on the part of the hierarchy is the cause of the unity of belief and profession in the Church.[xxv] The converse follows.
Elsewhere, Berry teaches that it is well-known “that the Catholic Church demands complete and unqualified acceptance and profession of all her teachings.”[xxvi] And all this echoes the countless teachings of the popes and Vatican I, stating that adherence to their doctrinal authority efficaciously leads to unity of faith.
But those that are apparently in authority generally do not demand this acceptance of their teaching and subsequent profession. In fact, they do not really seem to teach at all, nor do even the best of them seem sufficiently troubled by this disunity. On the contrary, they tolerate massive doctrinal disunity amongst the flock and most do nothing to remedy it. Some demand obedience to their office when they restrict the traditional Mass and private masses, or enforce holy communion in the hand, but this ‘weaponized orthodoxy’ is hardly teaching with authority. Imagine if bishops enforced adherence to the faith with the same authority with which they have imposed mask mandates, social distancing and track-and-trace forms. All this forms the background for a wider question: is it even possible for the Church to stop demanding “complete and unqualified acceptance and profession of all her teachings”?
Conclusion to Part I
Given the prevalence of such serious, conscious error, it is necessary to question whether our situation contradicts what the Church authoritatively teaches about her own unity. It certainly appears that we have a situation where there is a division in the Church’s profession of faith.
But it is impossible for the Church to lose one of her four marks. The Roman Catholic Church exists until the end of the world, retaining her essential nature and constitution – including her unity.[xxvii] There must, therefore, be a solution which preserves every aspect of the Church’s teaching about herself, whilst being in conformity with the facts that we see around us.
The teaching is certain: we have expressed it amply with magisterial texts and given an overview from Father Berry. We will establish it further with other theologians. However, the external facts are also certain. The division is real and visible. We cannot deny it. But sometimes we cannot see the wood for the trees, and so can interpret the facts wrongly.
To someone who has never heard of an eclipse, a photograph of such an event would look like a floating white ring against a black sky.
Someone who grew up under an extended eclipse (if such a thing were possible) might think that he is looking at one thing, a single floating white ring – but in reality he is looking at two separate things and taking them for a single thing. If it continued long enough, he might be led to believe that this floating white ring is the sun, or even redefine his understanding of the sun altogether.
He might never realise that a glorious brightness is being temporarily obscured by the moon.
To reassure readers, we affirm that the Roman Catholic Church is the mystical body of Christ, outside of which there is no salvation; that we profess and believe everything that she teaches; and that she remains in the world with all of her essential marks intact. We will examine this further in Part II.
