The date in this sentence is incorrect. The Holy See’s official itinerary for Pope Leo XIV’s apostolic journey to Monaco is titled “Apostolic Journey of the Holy Father to the Principality of Monaco (28 March 2026)” and lists the full schedule for that day. That directly contradicts the article’s claim that the visit happened on 17 January 2026.

Since this is a question about the date of a papal trip, the Vatican’s published itinerary is the strongest available evidence.

This sentence misstates the date of the legal change. The Holy See’s official list of Pope Leo XIV’s apostolic letters includes “Apostolic Letter issued ‘Motu Proprio’ of the Supreme Pontiff Leo XIV on the Composition and Presidency of the Pontifical Commission for Vatican City State” and gives the date as 19 November 2025. That contradicts the article’s claim that Leo signed it on 21 November 2025.

Because the correction is about the date of a specific Vatican legal act, the Holy See’s own document index is the most authoritative source.

This sentence is inaccurate about when Pope Leo XIV began living in the Apostolic Palace. Vatican News, citing the Holy See Press Office, reported on 14 March 2026 that Leo XIV would take possession of the Apostolic Palace apartment then, after having “resided at the Palazzo del Sant'Uffizio since the beginning of his pontificate.”

So while Leo XIV later did move into the Apostolic Palace, the article’s placement of that move in the immediate post-election/inauguration period is wrong. The Vatican’s own reporting makes clear that he only moved there in March 2026, not at the start of his papacy in May 2025.

This sentence misstates the Vatican’s own test for when lay followers incur excommunication for schism. The 1996 explanatory note of the Pontifical Council for Legislative Texts says formal adherence to the schismatic movement requires two complementary elements:

1. an internal element — freely and consciously sharing the substance of the schism, i.e. placing allegiance to Lefebvre’s followers above obedience to the Pope; and
2. an external element — outwardly manifesting that choice, with exclusive participation in Lefebvrist acts described only as the “most manifest sign.”

The same note adds that occasional participation alone is not sufficient, but it does not say excommunication applies only on the basis of attendance patterns. In other words, exclusive attendance is evidence, not the whole test.

The Dicastery for the Doctrine of the Faith’s 2 July 2026 note explicitly says it is adopting that 1996 standard for lay faithful. So the article’s simplified formulation is inaccurate.
