When you have been protected and insulated from Rome for so long, you begin to think one of two things:
1) Either you begin to think the SSPX is indefectible (in which case, it is a priori ridiculous that there could be any basis for resistance to the new direction in Menzingen);
or
2) In the opposite vein, you lose true belief there really is a state of general spiritual necessity caused by the apostasy in Rome.
In both instances, you are fertile ground for lending support to a merely practical accord (along the lines of that which the SSPX holds out future hope for, as evinced by the persistence of the 6 conditions; the 2012 General Chapter declaration; paragraph 11 of the June 27, 2013 Declaration of the Three SSPX Bishops; etc).
For a good (but sad) example of this latter phenomena, read this (and as you do so, ask yourself, was this interview given by Bishop Fellay?):
(Excerpts):
Why I Favor Our Superiors Legalizing Our Situation In The Church
Interview with Fr. Paul Aulagnier
Q. Do you think that the same reasons would be valuable today? Or are there any dangers in waiting for a reconciliation?
A. Today, the conditions would not allow for what was done in June of 1988. Several of my confreres will, perhaps, hit the roof when they become aware of this interview. It does not matter. I am free to state my judgment and I never liked yes men.
Why would the consecrations not be reasonable today? Because many Romans have changed and now acknowledge the very difficult situation in which the Church finds herself. Cardinal Castrillon’s Mass of May 24, 2003 is not burning straw. This is the fruit of a long evolution which began, it seems, around 1992, with the publication of a series of books of Cardinal Ratzinger and a series of conferences, homilies, and an interview with Cardinal Stickler. At St. Mary-Major, Cardinal Castrillon spoke for the Church by recalling the "right of citizenship" of the Mass of St. Pius V.
Pope John Paul II’s encyclical Ecclesia de Eucharistia vivit is also very important. Additionally, I think that there is a danger in seeing this conflict last for ages. The Church is a visible and hierarchical society. If one lives too long in an autarchy, one ends up losing the meaning of what a hierarchy is. We are thus in danger, the time passing and the opposition remaining, of forgetting Rome and organizing ourselves more and more outside of Rome. This needs to be acknowledged.
This is why we must always remain in contact with Rome, not only for them to progress in the right direction, but unceasingly to remind ourselves of their good memory. We are of the flock. If we remain satisfied with our situation, then there is a danger of "psychological schism." The young people are of my opinion. I call it as it is. The SSPX leadership thinks I exaggerate, but our younger generations have never known a normal ecclesiastical situation. Thus I have accepted "this Canadian exile" for my ideas.
Q. Why do you believe that the reconciliation of Bishop Rifan and his priests is a positive step not only for the traditionalists of Campos, but for every traditional Catholic?
A. One reason is the danger of schism which I just expressed. Secondly, my friendship with these heroic priests has led me to experience their traditional parishes and their numerous works. I have especially seen even here the problem of the Mass. The attitude of Rome is new. Rome gave the Mass to our friends, the priests of Campos. And this freely and without condition. Rome recognizes their right, their facultas to celebrate the Traditional Mass in all the churches of their apostolic administration. I studied their statutes at length. So, for me, these things are going in the right direction in favor of the Mass.
The Campos agreement did not require the compromises made by the Ecclesia Dei institutes in 1988. Campos received a frank recognition of the right to the Tridentine Mass without having to recognize that the new Mass is "legitimate and orthodox." They were simply asked to recognize the validity of the new Mass. Archbishop Lefebvre always recognized and taught that the new Mass was valid. There is a great difference between "validity," "legitimacy," and "orthodoxy." Something can be valid without being legitimate and orthodox.
Q. Many priests of your Society, including Bishop Fellay, have praised the new encyclical of the Holy Father Ecclesia de Eucharistia. Do you consider the new encyclical to be a positive sign on the doctrinal and liturgical level?
A. Yes and greatly so. This encyclical is truly a positive sign on the doctrinal and liturgical level. One sees here an authority that is newly aware of the drama which affects the Church and her liturgy. The liturgical reform, such as it was conceived and applied after the council, has denatured the liturgy by not respecting its end. The liturgy is essentially worship rendered to God. The priest offers, in the name of the people, "for the living and the dead," for the people who are united to this action, the sacrifice of Christ which renders to God "all honor and all glory.
The Catholic liturgy has a transcendent dimension. It orients us toward God. It subjects us to God. There is a similarity between the Roman liturgy and the heavenly liturgy. Read the Book of the Apocalypse of St. John and you will see that heavenly worship is directed toward the Father and the Lamb of God, the paschal Lamb to whom the angels and the elect sing and magnify the power, the divinity, the glory, the sanctity of God. The Sanctus of our Mass is a divine praise. All this is, for many, lost, so much so.
The Catholic hierarchy is finally aware of it. It is never too late in order to do good. It wants to correct the "shadows." How can one not rejoice at this? This is yet another reason why I favor our superiors legalizing our situation in the Church. It is necessary today to be inside with a recognized right of the Mass of St. Pius V on the altars of Christianity. One must have the sense of what is possible. To ask too much is to ask for nothing. The Holy Father has spoken. We must help and participate in the liturgical restoration in the Church.
An Apostolic Administration
Q. In the context of these positive stages, is the reconciliation of the SSPX with Rome possible in the near future?
A. One Mass does not establish a custom. Thus I will speak about restoration of normal relations between Catholics of goodwill. This restoration is more than desirable. It is necessary. In a month? In three years? I do not know. Yet the more that time passes, the more the restoration becomes urgent. But again, minds must be prepared.
Q. Do you think that the recent transfer of Bishop Williamson to Latin America has a link with the eventual reconciliation of the SSPX and Rome?
A. I believe it was simply routine. One should not imagine conflicts or hidden reasons where none exist. Granted, Bishop Williamson is one of the most firm opponents to a reconciliation with Rome. But that has nothing to do with his transfer to Argentina. He will likely remain opposed in La Reja. He is suspicious in nature. And suspicion leads to error. He thinks that "the Romans," as he likes to say, have not changed. It is his opinion. This opinion is dominant with Bishop Fellay today, but will it be tomorrow?
Q. Considering your friendship and close proximity with Archbishop Lefebvre, do you think that he would have accepted the offer of reconciliation that Rome had recently presented to the SSPX in the line of the accords of Campos?
A. I sincerely believe that today Archbishop Lefebvre would have accepted an accord with Rome. He would have been, perhaps, more cautious and demanding on certain points than Bishop Rangel, but the archbishop would have gone to the end this time. The requirements Rome demanded of the Campos traditionalists are these: the recognition of Pope John Paul II as the legitimate Successor of Peter, the recognition of the Second Vatican Council interpreted in the light of Tradition, the recognition of the validity of the Novus Ordo Missae, and a free discussion of the council that avoided dialectic and polemic. Archbishop Lefebvre had already accepted this in 1988. One should not be afraid to say this, and I wish someone would tell me why they should not be accepted today.
The moral of the story is this:
Complacency is punished by reunion with unconverted Rome (which tends towards heresy).
