Unam Sanctam Catholicam: Cum Ex Apostolatus and Loss of Office

 +

JMJ

I think that the biggest challenge in assessing the Sedevacantist Thesis is perspective.

A good bit of perspective is provided by Unam Sanctam Catholicam (USC) in an article published in October 2022.

The basic thesis is that becuase of Cum Ex Apostolatus, a bull issued by Pope Paul IV in 1559, "a heretic cannot be elected as Pope."

I have a lot of issues with the thesis. The first of which is 'how do you know that a person is a heretic in the formal sense?'  My general thought is that either the person in question tells you or the Church tells you.  

  1. Is the 'heresy' clearly against a De Fide Truth of the Catholic Church? This is really important. 
    1. Let's take 'Extra Ecclesiam Nulla Salus' - outside the Church there is no salvation. However, Popes have said that protestants can be saved. The solution to this conundrum is that both statements are true if one understands what the Church has taught in regard to both statements.  So - not all statements that appear heretical are de facto heretical.
    2. Is the statement contradicting a De Fide truth of the Catholic Church or some lesser doctrine.
  2. What is the disposition of the person making the statement? Do they know that what they are saying goes directly against a De Fide teaching?  Do they refuse to amend their way when corrected by authority?
  3. Has an inference been made?  In other words are the people who claim that this or that pope is/was a heretic making an assumption?
  4. I have attached a ChatGPT summary of McHugh and Callan's 1958 treatment on the subject below.

Moving on ...

To help in expanding one's perspective, I've attached ChatGPT summaries of both USC and McHugh and Callan's texts below.

ChatGPT Summary: Cum Ex Apostolatus and Loss of Office


 Here’s a structured mind map capturing the key points of the article “Cum Ex Apostolatus and Loss of Office” from *Unam Sanctam Catholicam*, organized into main themes and subpoints:


Mind Map: *Cum Ex Apostolatus and Loss of Office*


1. Context & Core Issue


  • Focuses on the *Sedevacantist* interpretation of Pope Paul IV’s 1559 Bull *Cum Ex Apostolatus Officio*.

  • The article critiques the claim that recent Popes are invalidly elected based on this Bull ([Unam Sanctam Catholicam][1]).


2. Sedevacantist Interlocutor's Argument


  • They invoke the Bull’s prohibition that only Catholics—excluding former Catholics who are public and manifest heretics—can be elected Pope ([Unam Sanctam Catholicam][1]).

  • They liken certain post-conciliar popes to Cardinal Morone, whom Paul IV barred and imprisoned for supposed heresy ([Unam Sanctam Catholicam][1]).


3. Defenses by Ryan Grant (“Defensor Fidei”)


  • Argues the Sedevacantist reading is mistaken, using:

    • Historical context

    • The 1917 Code of Canon Law

    • First Vatican Council teachings

    • Pius XII’s guidance ([Unam Sanctam Catholicam][1]).


4. Interpretive & Canonical Principles


  • Major point: In canon law, restrictive laws are interpreted narrowly, while permissive laws broadly—an interpretive principle the interlocutor challenges ([Unam Sanctam Catholicam][1]).

  • The article affirms this principle as crucial to understanding the Bull correctly ([Unam Sanctam Catholicam][1]).


5. “Correction” vs. “Removal”


  • The interlocutor claims that the Bull implies the Pope can be judged or removed for heresy ([Unam Sanctam Catholicam][1]).

  • Grant counters that the Bull’s reference to correction does not equate to removal from office—the Pope could be corrected but still retain office ([Unam Sanctam Catholicam][1]).


6. Pius XII’s Viewpoint


  • Cited by Grant to show that an excommunicated person can be validly elected Pope, contrary to the interlocutor’s implication that Cum Ex Apostolatus would invalidate such an election ([Unam Sanctam Catholicam][1]).

  • This underscores the interlocutor's misreading of the Bull.


7. Conclusion


  • The article concludes that the Sedevacantist position based on *Cum Ex Apostolatus* is fundamentally flawed.

  • The Bull does not support claims of automatic invalidity or removal of recent Popes, especially under proper canonical interpretation and later Church law ([Unam Sanctam Catholicam][1]).

ChatGPT Summary: Heresy by McHugh and Callan 1958


 Summary: Heresy

Definition (826)


  • Heresy = a manifest error against the faith, obstinately assented to by one who has sincerely embraced the Christian faith.

  • Not heresy:

    • Outward denial without inward disbelief.

    • Doubts not assented to.

  • True heresy requires positive error opposed to Catholic divine faith.

Key Elements

1. Error opposed to faith

  • Must contradict revealed truth or Church dogma.

  • Errors against private revelations or non-dogmatic teachings ≠ heresy.

2. Manifest opposition

  • Must clearly contradict defined dogma (e.g., denying sacraments).

  • Denying uncertain/probable matters is not heresy.

3. Obstinate assent

  • Essential trait: knowingly refusing Church truth.

  • Ignorance (invincible) excuses from formal heresy.

  • Motivations (pride, passion, fear) don’t matter—consent is enough.

4. Subject

  • Applies to baptized Christians (not Jews, infidels, catechumens).

Sin vs. Crime (827)

  • Sin of heresy (before God): broader, includes any rejection of divine truth.

  • Canonical crime of heresy (before Church): narrower, requires formal conditions (public, baptized, retaining Christian name).

Kinds of Heresy (828–829)

  • Positive: affirming error.

  • Negative: denying truth.

  • Internal: in the mind only.

  • External: expressed outwardly (words/acts).

  • Occult: hidden or private.

  • Public/Notorious: openly known.

  • Formal: obstinate, conscious rejection of truth.

  • Material: mistaken, but in good faith.

Material vs. Formal (829–830)

  • Formal heresy:

    • Knowingly reject divine revelation.

    • Consent to error = pertinacity.

  • Material heresy:

    • Error from ignorance or poor formation.

    • No guilt if ignorance is invincible.

Moral Weight (831–832)

  • Formal heresy: always a grave sin.

  • Material heresy: not sinful if ignorance invincible; sinful if negligent.

  • Circumstances:

    • Public, external, or tied to apostasy = aggravating.

    • Multiple dogmas denied = multiple sins.

In essence:

Heresy requires obstinate, conscious rejection of divine Catholic faith after baptism. Formal heresy is always gravely sinful; material heresy may or may not be sinful depending on knowledge and intent.

News Roundup: October 19, 2026

 + JMJ Well ... I was looking in my blog drafts and found this list from after my News is an Addiction post. So ... yep ... not totally able to disconnect from the news world at this point.  Frankly, I haven't read all of these articles - they catch my eye as I check for SSPX news regarding the exco's etc. So let's consider these topics as part of a higher level chronicle. They may not be key inflection points but helps to understand the flow of the world as perceived by the authors and myself who captured them as a snapshot in time.

The Debt Canadian Traditional Catholics Owe to Fr. Yves Normandin (RIP)

 + JMJ On this All Souls day, I'd like to remind all Traditional Catholics in Canada the debt that they owe to Fr. Yves Normandin (RIP). Fr. Normandin stepped into the breach in the 1970's offering the Tridentine Mass across Canada for close to a decade before returning to his diocese for a number years before returning to the SSPX. I had the grace to visit him in Quebec twice and each time left with a greater appreciation of the fruits of his efforts. All of us 'old-timers' probably remembers Masses in Chapels, Homes, Halls, Funeral Homes, and event convention centres. I make the assertion that this laid the ground for all the Traditional Mass Communities, SSPX, FSSP, Diocesan and others. Probably a pretty safe assertion! In addition to praying for the repose of the Soul of Fr. Normandin, I'd ask you also pray for the repose of the soul of his Mother.  I remember seeing her picture once and everyone has a Mom and she is worthy of our prayers for producing such a so...

Morning and Evening and other sundry Prayers

+ JMJ Along the theme of P^3 (Prayer, Penance, Patience), and for my own reference ... here is a collection of Morning and Evening prayers from the Ideal Daily Missal along with some additional prayers. In this crisis of the Church, I do not think it is possible to do too much prayer, penance and have patience. P^3

SSPX: Requiescat in Pace - Nov. Devotions

 + JMJ Recently, the St. Gertrude prayer was recommended to me and given my devotion to the Holy Souls in Purgatory, I thought it a good inclusion in the morning prayers and post it here for as a reminder for November - the Month of the Holy Souls. P^3 Courtesy of SSPX.org “Forget not the dead and hasten to pray for them!” - such is the Church's recommendation, beautifully summarized by St. Augustine. In Purgatory until the End of the World Our Lady Herself referred to Purgatory when, at the first Fatima apparition in May 1917, she was asked by Lucia about the souls of two young village girls who had recently died. The Virgin answered that the first one, Maria das Nevas, who died when about 16 years of age, was in Heaven. But of Amelia, a young lady of 18 years at her death, "will be in purgatory until the end of the world.” The disclosure about Amelia’s prolonged period of expiation never fails to shock and trouble. We are so easily misled to believe that Heaven is our natura...

The News is an Addiction ...

 + JMJ People seem to be mesmerised by train wrecks.   They just can't turn away as the disaster creeps forward along train tracks towards the crossing where a car, truck, bus, trailer awaits its destruction. Trads have been watching the train wreck that is this crisis of the Catholic Church for decades. The trade war between the Canada and the US has reminded me that the news is addictive.   The first time I was addicted what from 2009 to  2014 when I was closely following the Rome / SSPX discussions.  I was at work watching a live-stream as Bishop Fellay disappeared into the Vatican. The lead-up to this moment had been intense as the 'resistance' got freaked out and the cultural cracks between doctrine and conspiracy theory widened. In the decade since then other things have emerged, wars, rumours of wars, conspiracies, celebrity Catholics etc. Now we have a new addiction and its name is Trump. Lately, no matter how much I try, I find myself wonderin...
