A faction of traditionalist Catholics affiliated with the Society of St Pius X (SSPX) is set to consecrate four bishops in Écône, Switzerland, in a move that further deepens its longstanding conflict with the Vatican. The event, scheduled for today, marks a significant rupture between the group and the Holy See, and is expected to prompt immediate excommunications.

Founded in Écône in 1970 by a conservative French bishop, the SSPX remains staunchly opposed to the reforms of the Second Vatican Council in the 1960s. The society insists on the use of the traditional Latin Mass rather than the modern vernacular liturgies introduced by the council, which it regards as doctrinal errors. This theological opposition has defined its relationship with the Catholic Church for decades, resulting in periods of tension and limited dialogue.

The consecration ceremony has been organized with a level of polish that resembles a corporate event, complete with a dedicated website offering accommodation options ranging from home stays to hotels, along with meal packages available via festival-style wristbands. Souvenir items, including commemorative baseball caps and a box of four bottles of wine priced at 75 Swiss francs, are available. Each bottle bears symbols associated with episcopal authority, such as a ring, cross, crozier, and mitre, representing the four bishops to be consecrated.

The move challenges the authority of Pope Leo XIV, who alone holds the canonical prerogative to appoint bishops. In response to the impending consecrations, the Pope issued an open letter urging the SSPX not to proceed. He warned that the act would constitute a "schismatic act" and described it as a "sin of extreme gravity." Pope Leo XIV’s intervention represents a last effort to prevent a formal break, emphasizing the severity with which the Vatican views the planned consecrations.

Observers note that the event solidifies a fissure within the Church that has persisted for decades. Massimo Faggioli, a professor of theology and Vatican expert, described the consecrations as “an earthquake for the Church, but not a surprise.” He added that the SSPX’s resistance to the Second Vatican Council has been unwavering, and this ceremony formalizes a rupture that was expected.

Thousands of priests, bishops, and followers of the SSPX are expected to attend the gathering, marking a critical moment in the ongoing dispute between traditionalist Catholics and the Vatican’s efforts to engage with and reconcile such groups. The consecrations underscore the deep divisions over liturgical practice and ecclesiastical authority that continue to challenge the Catholic Church’s unity.
