The article dates the required Professio fidei to 1998, but the sources do not support that.

In the text of Cardinal Müller’s 6 June 2017 letter as published by the SSPX itself, he says the Society must adhere to “the new form of the Professio fidei dating from 1988.” That directly contradicts the article’s wording.

The Vatican’s official page titled “PROFESSION OF FAITH” also distinguishes the dates clearly. Its prefatory material says the collection includes:

• the Profession of Faith and Oath of Fidelity published on 9 January 1989;
• John Paul II’s motu proprio Ad tuendam fidem from 1998; and
• the 1998 doctrinal commentary on the concluding formula.

So 1998 is the date of later explanatory / juridical documents, not the date of the profession formula Müller was invoking. Whether one refers to the formula as dating from 1988 (its approval) or 1989 (its publication), calling it the “1998 profession of faith” is incorrect.

The article overstates what the Holy See actually did on 2 July 2026.

In the official decree, the Dicastery for the Doctrine of the Faith does not say it is excommunicating the SSPX as a whole. It specifically declares that Alfonso de Galarreta, the four newly consecrated bishops (Pascal Schreiber, Michael Goldade, Michel Poinsinet de Sivry, and Marc Hanappier), and Bernard Fellay incurred excommunication. The same decree then warns clerics and lay faithful not to adhere to the SSPX’s schism, because they would thereby incur excommunication.

The accompanying explanatory note broadens the pastoral/juridical consequences, but still does not say the fraternity as an institution was excommunicated wholesale. Instead, it states that sacred ministers belonging to the SSPX are to be considered in schism, and that lay faithful are considered schismatic and excommunicated only if they formally adhere under the conditions described in the 1996 explanatory note.

This matters because the article’s wording suggests a blanket excommunication of the SSPX as an institution. The official documents describe a more specific situation: named individuals are declared excommunicated, sacred ministers are treated as schismatics, and laity are affected only insofar as they formally adhere.

That narrower, person-focused approach is also consistent with Benedict XVI’s 2009 clarification that “The excommunication affects individuals, not institutions.”
