Pope Leo XIV Pleads with Breakaway Catholic Group to Avoid 'Sin of Extreme Gravity'

Pope Leo XIV issued an urgent plea Tuesday to the traditionalist Society of St. Pius X (SSPX) to abandon its plans to consecrate four bishops without Vatican approval, warning that the act would be a "sin of extreme gravity" and could lead to excommunication.

In a letter addressed to the Rev. Davide Pagliarani, the SSPX leader, the pontiff implored the group to reconsider before the planned ceremony in Econe, Switzerland. Pope Leo XIV stated that the consecrations would place the bishops involved outside the Church's communion.

"I plead with you and ask you with all my heart: please turn back!" the pope wrote.

Under church law, consecrating bishops without papal approval is considered a schismatic act, carrying automatic excommunication for those involved in the ceremony. The pope emphasized the potential harm to the faithful, writing that "the schismatic act you are about to undertake would deprive them of the licit, and in some cases, even valid reception of the sacraments."

The dispute represents the first major challenge of Pope Leo XIV's pontificate. Since assuming the papacy, the American-born pontiff has focused on healing divisions within the Church, including tensions with traditionalist Catholics.

The Society of St. Pius X, founded after the Second Vatican Council, rejects many of the council's reforms, including the widespread use of Masses in local languages instead of Latin. The group asserts it is preserving authentic Catholic teaching and has defended its decision to consecrate new bishops by citing a "state of necessity" to provide leadership for its followers.

This planned consecration echoes a similar confrontation in 1988, when the SSPX founder, Archbishop Marcel Lefebvre, consecrated four bishops without papal consent. At that time, the Vatican responded by excommunicating Lefebvre and the newly ordained bishops, although these excommunications were lifted in 2009 as part of an effort to reconcile relations.

Despite years of dialogue, the SSPX remains outside the Catholic Church's formal structure. The society has grown in recent decades, reporting hundreds of priests and seminarians globally, making it one of the largest traditionalist movements operating independently of the Vatican's official authority.
