Vatican Excommunicates SSPX Clergy Over Unauthorized Bishops
The Vatican announced Thursday that it has excommunicated the clergy of the Society of St. Pius X (SSPX), a traditionalist Catholic group, after SSPX’s leaders consecrated four new bishops without the approval of Pope Leo XIV. Church officials described the conflict as the largest schism within the Catholic Church since the late nineteenth century.
The decision followed a ceremony held Wednesday in Écône, Switzerland, where SSPX leaders proceeded with the consecrations despite a personal appeal from Pope Leo XIV asking them not to do so. The Vatican stated that the ceremony violated canon law and represented a direct challenge to papal authority.

The Society of St. Pius X was founded in 1970 by Archbishop Marcel Lefebvre in opposition to reforms introduced by the Second Vatican Council. The group has long criticized changes to Catholic practice, such as celebrating Mass in local languages instead of Latin and promoting dialogue with other religions. Tensions between the Vatican and SSPX previously escalated in 1988 when Lefebvre consecrated bishops without papal approval, leading to excommunications that were later lifted in 2009 by Pope Benedict XVI. Tensions have since been reduced through various initiatives, including Pope Benedict XVI’s initiative of lifting excommunications on the four SSPX bishops in 2009, Other initiatives to reduce tensions include Pope Francis’ granting of faculties to SSPX priests to hear confessions, and the Vatican’s allowing SSPX priests to celebrate certain marriages under diocesan supervision.

The decree affects at least 750 SSPX priests and could impact hundreds of thousands of followers worldwide. Vatican officials estimate that the group has between 300,000 and 600,000 supporters. While lay members are not automatically excommunicated, they may face penalties if they continue to participate in SSPX activities and refuse to affirm their loyalty to the pope and the Catholic Church.
In addition to the excommunications, the Vatican declared that sacraments performed by SSPX priests, including marriages and confessions, are no longer considered valid. Church leaders also urged Catholics to stop attending SSPX Masses and events.
Religious scholars say Pope Leo’s decision marks a significant shift in the Vatican’s approach. Rather than continuing decades of attempted reconciliation, the pope has chosen to formally separate the Church from a movement he views as openly defiant.
Despite the sanctions, SSPX leaders expressed confidence that the organization will endure. Priests within the group stated that they expect continued support from followers and believe future dialogue with Rome remains possible.
