The Vatican has formally excommunicated members of the Society of St. Pius X (SSPX) after the Swiss-based traditionalist group ordained four new bishops without papal authorization. This move marks a significant shift in governance under Pope Leo, confirming his commitment to the doctrinal reforms established during the Second Vatican Council in the 1960s, according to experts.
Why did the Vatican excommunicate the Society of St. Pius X?
The excommunication stems from the unauthorized ordination of four bishops on Wednesday, an act the Church views as a direct challenge to papal authority. According to the Vatican’s top doctrinal watchdog, the consecration of bishops without the Pope’s approval violates a fundamental requirement intended to maintain the Church’s historical link to Jesus’ 12 apostles. This action causes those taking part in the ceremony to be automatically excommunicated, or “out of communion” with the wider Church, and unable to receive sacraments until they repent and ask for forgiveness.

The Society of St. Pius X currently counts 733 priests worldwide. The group maintains a rejection of the Second Vatican Council’s reforms, particularly the transition from Latin-only Mass to local languages, which they reject, citing a desire for the Latin rite’s sense of mystery and formality.
How does Pope Leo’s leadership style compare to his predecessors?
While Pope Leo entered his papacy promising to unify a divided Church and avoid autocratic rule, observers note he is increasingly willing to draw firm lines regarding doctrinal obedience. Elise Allen, author of a biography of Pope Leo for Penguin Peru, notes that while the Pope is not inherently confrontational, he “is somebody that does not work in blurred lines.”

This contrast is visible when compared to the approach of the late Pope Francis. While Francis sought to restrict the Latin Mass, he simultaneously made several symbolic overtures to the SSPX, including authorizing them to hear confessions on behalf of the Church. By contrast, Chicago Cardinal Blase Cupich, a close ally of the current Pope, emphasizes that under Leo, the reforms of the Second Vatican Council are no longer considered “optional” or open to “perpetual debate.”
What is the significance of the Second Vatican Council to this conflict?
The Second Vatican Council, or “Vatican II,” remains a point of contention between the Vatican and the SSPX. The Council introduced reforms that modernized the Church’s liturgy and sought to improve relations with other Christian denominations and the Jewish community. For Pope Leo, who spent decades before becoming pope as a missionary and bishop in Peru, the Council is foundational. David Gibson, a Vatican expert and academic at Fordham University in New York, notes that the Pope views the SSPX’s defiance not merely as a disagreement with his own authority, but as “contempt for the entire Catholic community and tradition.”
Pro Tip: Understanding Church Authority
In Catholic theology, the Pope holds the exclusive right to authorize the consecration of bishops. This process is intended to ensure doctrinal unity and maintain the Church’s ties to Jesus’ 12 apostles. Unauthorized ordinations are considered a serious breach of Church law.
