Catholic Candle note: The article below shows the invalidity of an excommunication against a good man when it is imposed because he is a good man. One such excommunication was against Archbishop Lefebvre because he was good and upheld the truth.
But a reader would be wrong in supposing that this article supports the current “new” SSPX, which is trending liberal and no longer follows the course set out for the SSPX by their founder, Archbishop Lefebvre.
Here are a few of the many proofs that the “new” SSPX is liberal and should not be supported in any way:

Further, sedevacantism is wrong and is (material or formal) schism. Catholic Candle is not sedevacantist.
Below is the eighteenth article in a series which covers specific aspects of the error of sedevacantism. As context for this eighteenth article, let us recall what we saw in the earlier seventeen articles:
In the first article, we saw that we cannot know whether the pope (or anyone else) is a formal heretic (rather than a material heretic only) – and thus whether he is outside the true Catholic Church based simply on his persistent, public teaching of a heretical opinion.1
Then, in the second article, we saw that we must not judge a man to be a formal heretic if he professes to be Catholic and says he believes what a Catholic must believe now, in order to be Catholic now. When a person professes a heretical opinion, we must judge him in the most favorable light (if we judge him at all). So, we must avoid the sin of rash judgment and we must not judge negatively the interior culpability of the pope and the 1.4 billion2 people who profess to be Catholic. We must not judge they are not “real” Catholics if they tell us that they are Catholics. Instead, we should count them as Catholics who are very confused or are uninformed.3
Thus, we must judge the conciliar popes to have been material heretics, not formal heretics (if we judge them at all), and that each was pope in his turn until his death (or abdication). Regarding any of the world’s 1.4 billion self-described Catholics who hold heresy, we must judge them to be material heretics only (if we judge them at all), unless they themselves tell us that they know they don’t qualify to be Catholics.4
In the third article, we examined briefly the important difference between persons in authority who fulfill their duty to judge those under their charge in the external forum, as contrasted to a sedevacantist or anyone else except God who judges the interior culpability of other persons and (rashly) judges them to be formal heretics.5
In the fourth article, we saw that it does not help us to protect ourselves better from a conciliar pope’s heresy, to declare that we know he is not the pope and is not a Catholic.6
In the fifth article, we saw that it is possible for a pope to teach (or believe) heresy and in fact, popes have taught and believed heresy at various times during Church history.7 We looked especially at the cases of Pope John XXII and Pope Nicholas I, who both taught explicit heresy while pope and nonetheless continued to be the pope. Pope John XXII also taught the same explicit heresy before he became the pope.
In the sixth article, we saw that the Church infallibly assures us that we will have a pope at all times until the end of the world, except during very short interregnums between papal reigns, during which the Church is in the process of electing a new pope and during which the Church’s unified government continues to function.8 In this sixth article, we saw that we are not presently in an interregnum (even though the sedevacantists absurdly claim we are in a many-decades-long interregnum).
In the seventh article of this series, we saw that the Catholic Church is a visible Body and remains visible to all. The Catholic Church has a visible monarchical government and the pope is visible to all. Thus, we know we have a pope and that the one who is pope is visible (known) to all as the pope.9
In the eighth article, we saw that the necessary visibility of the Catholic Church and the pope requires as a corollary that the one who virtually all Catholics see (i.e., believe) is the pope must be the pope, since the pope must be visible to all.10
In the ninth article, we addressed the superficial claim of sedevacantists (addressed to Catholics) saying that “if you think we have a pope, then you have to obey him in whatever he tells you to do”. We examined the true Catholic virtue of obedience and saw that we must not obey the commands of even a real superior like our pope, if/when he commands us to do something evil.11
In the tenth article, we saw more deeply what schism is and how sedevacantism is inherently schism.12
In the eleventh article of this series, we saw more deeply how we should respond to a pope (or other superior) who does harm – viz., we should recognize his authority but resist the evil of his words or deeds.13
In the twelfth article of this series, we saw how we ordinary Catholic laymen can recognize what the Catholic Truth is and how we can know when the pope (or anyone) is promoting heresy or other error.14
In the thirteenth article of this series, we saw the falsehood of a related sedevacantist error (or “half-truth”), claiming that we have no pope because the conciliar popes had doubtful consecrations and/or ordinations.15
In the fourteenth article of this series, we considered another way to see that sedevacantism is wrong and sinful, viz., because it is the sin of revolution.16
In the fifteenth article of this series, we saw that even though Pope Leo XIV is objectively a very bad pope, all Catholics are in communion with him, since this is an essential condition of being Catholic and not schismatic.17
In the sixteenth article of this series, we considered the position (and saw the error) that those who pray for the pope in the Canon of the Mass are declaring that they adopt his errors.18
In the seventeenth article of this series, we saw that we must have a pope because the Fatima apparitions show that a pope will consecrate Russia to the Immaculate Heart of Mary.19
Now in the eighteenth article of this series, we consider whether excommunication is invalid if a person is excommunicated for being good or for defending the Catholic truth.
Since
Pope John Paul II was a real pope, does that mean that Archbishop
Lefebvre was really excluded from the Catholic Church by the pope
excommunicating him?
Some sedevacantists seek to trap uninformed Catholics into believing that, if they support the position of good men, such as Archbishop Lefebvre, then they must declare that the post-Vatican II popes are not real popes.
One example of that trap is when the sedevacantists present a false alternative:20 either:
-
Declare that Archbishop Lefebvre died outside the Catholic Church;
or
-
Agree that John Paul II was not a valid pope.
But even if the sedevacantist who lays that trap is himself simply ignorant, we show (below) the error of this false alternative trap.
Short answer to the
Sedevacantist Question
The pope has the power to decide
whom to excommunicate. However, those excommunications have no
effect if they are imposed unjustly.
Discussion and explanation
This question directly pertains to the pope’s power to excommunicate a wayward subordinate. But let us examine this power in its proper context of the more general powers that a superior (including the pope) possesses, to govern the community over which he is superior.
A pope must use his authority to keep order in the Church that he governs, and therefore he must punish wayward subordinates.
This duty is analogous to that of the father of a family, who must govern for the good of his family. This duty is also analogous to the duty of a civil ruler, who must govern for the good of civil society.
Civil and ecclesiastical superiors cannot read the interior souls of their subordinates any more than parents can read the souls of their children. Thus, the superior cannot infallibly determine his subordinates’ subjective interior culpability for their words and deeds.
But because superiors must care for the communities they govern (as a father governs his family), they must punish their subordinates who do evil things.21 They must do their best to administer justice, although they might judge mistakenly.22 God will judge how diligently those superiors sought justice.
St. Thomas Aquinas, greatest Doctor of the Catholic Church, warns those whose duty is to judge to do it carefully and justly. Here are his words:
Through an unjust sentence a judge destroys a man, nonetheless he renders an unjust sentence in vain. The power of binding and loosing is given only for building, not for destroying.”23
A civil judge can possibly misjudge an accused person of having inner guilt, but must judge based on the best available outward evidence and punish criminals as justly as possible. Likewise, because Church officials protect the Church community that they govern (e.g., the whole Church, in the case of the pope, or a diocese, in the case of a bishop, etc.), they must punish wrongdoers as justly as possible despite the possibility of misjudgment.
When a heretic (or other evildoer) refuses to repent despite his ecclesiastical superior’s efforts to convince him, that superior must punish him. Among other punishments, that superior can excommunicate him, i.e., exile him from the community.24
From all the above, we see that excommunication is a necessary ecclesiastical power and part of good governing. But in a given case, fallible Church superiors might excommunicate unjustly25 (without adequate cause or judicial process), and therefore invalidly.26 In other words, it would be a great error to suppose that papal excommunications are always valid and can never be void. An excommunication must just in order to be valid.
St. Thomas, quoting St. Augustine, both cautions ecclesiastical judges to judge carefully and also declares that unjust censures have no force. Here are their words:
When Our Lord grants to the hierarchy the power to “bind [a person] on earth”, St. Augustine warns Church leaders: “Make sure that you bind justly, for justice shatters bonds which are unjustly imposed.”27
Applying this principle to Pope John Paul II’s purported
excommunication of Archbishop Lefebvre, that penalty was plainly
invalid and of no effect because that penalty was imposed because
Archbishop Lefebvre defended Catholic Tradition. This is similar to
Pope Liberius invalidly excommunicating St. Athanasius for his
orthodoxy.28
Summary of this Article
The pope must use his authority to govern the Church wisely and render judgment justly. By his own authority, the pope can and must excommunicate seriously wayward, incorrigible subordinates.
The pope has the power to decide who to excommunicate. However, those excommunications have no effect if they are imposed unjustly – as would be the case when a person is excommunicated for defending the Catholic Faith. In other words, excommunications are not automatically valid.
The fact that it is possible for a pope to invalidly and unjustly proclaim an “excommunication” does not in any way serve as evidence that he is not a valid pope.
This truth “gives the lie” to the sedevacantist trick argument:
-
Archbishop Lefebvre was good.
-
John Paul II excommunicated Archbishop Lefebvre.
-
Therefore John Paul II cannot have been a real pope.
The truth is that Pope John Paul II was a valid pope but was simply abusing his authority and acting unjustly toward Archbishop Lefebvre.

We
Must Pray for the Pope, Especially at Mass!:
https://catholiccandle.org/2026/01/26/we-must-pray-for-the-pope-especially-at-mass/
20 Many sedevacantists are “experts” at using “false alternative” traps. For example, they assert to unwary Catholics: “You are required to accept any liturgical changes that a valid pope promulgates, therefore you must either:
-
Accept the new mass;
or
-
Agree that Paul VI (who promulgated the new mass) was not a real pope.
For purposes of this article, we do not need to determine whether the sedevacantists are culpable for such false arguments. Maybe they are merely ignorant. God will judge that, not us. We only need to be aware of their objectively false arguments so that we can help guard ourselves and others against them.
21 Here is how St. Thomas explains this principle that we are obliged to obey (and can be justly judged) only by those superiors who are our superiors at the time we are acting:
Judgment ought to be congruous as far as concerns the person of the one judging. … It is not prohibited to superiors but to subjects; hence they [viz., the superiors] ought to judge only their subjects.
St. Thomas Aquinas, Lectures on St. Matthew’s Gospel, ch.7, §1.
St. Thomas elaborates on this truth:
[J]ust as a law cannot be made save by public authority, so neither can a judgment be pronounced except by public authority, which extends over those who are subject to the community [i.e., subject to that particular public authority]. Wherefore, even as it would be unjust for one man to force another to observe a law that was not approved by public authority, so too, it is unjust, if a man compels another to submit to a judgment that is pronounced by anyone other than the public authority.
St. Thomas Aquinas, Summa, IIa IIae, Q.60, a.6, respondeo (bracketed words added for clarity).
22 Here is how Pope St. Pius X explains the duty of ecclesiastical superiors to judge in the external forum and punish their subordinates’ evil deeds, even though the subordinate might not be interiorly culpable for any sin:
Although they [the Modernists] express their astonishment that We should number them amongst the enemies of the Church, no one will be reasonably surprised that We should do so, if, leaving out of account the internal disposition of the soul, of which God alone is the Judge, he considers their doctrines, their manner of speech, and their action [which are the outward, objective criteria upon which a man judges in the external forum].
Pascendi, St. Pope Pius X, §3 (emphasis and bracketed words added).
Thus, as Pope St. Pius X explains, a superior might be mistaken about “the internal disposition of the soul, of which God alone is the Judge” but nonetheless, the superior must protect the community over which he has authority, by judging the outward conduct of wrong-doers under him (and punishing, where necessary).
23 St. Thomas’ Lectures on St. Matthew’s Gospel, ch.23, #1858.
24 The Summa explains that “excommunication is the most severe punishment”. Summa Supp., Q.21, a.3, respondeo.
25 The Summa explains this truth as follows:
An excommunication may be unjust … on the part of the excommunication, through there being no proper cause, or through the sentence being passed without the forms of law being observed. In this case, if the error, on the part of the sentence, be such as to render the sentence void, this has no effect, for there is no excommunication.
Summa Supp., Q.21, a.4, respondeo (emphasis added).
26 Emphasizing the ineffectiveness of a void excommunication on a man’s charity (and therefore his possession of sanctifying grace and salvation), the Summa adds:
No man can be justly excommunicated except for a mortal sin, whereby a man is already separated from charity, even without being excommunicated. An unjust excommunication cannot deprive a man of charity, since this is one of the greatest of all goods, of which a man cannot be deprived against his will [showing the truth that committing a mortal sin is voluntary].
Summa Supp., Q.21, a.1, ad 2.
