Pope Leo XIV has excommunicated a small, conservative Catholic sect known as The Society of Saint Pius the X (SSPX) after the group ordained four bishops without papal approval. This action marks the first schism of his pontificate and represents a firm stance by the first American pope.

David Gibson, director of the Center on Religion and Culture at Fordham University, discussed the implications of the pope's decision, suggesting that the Vatican's handling of this group mirrors dynamics seen in contemporary U.S. politics. The SSPX, described as traditionalist and deeply conservative, has pushed for a special dispensation to maintain its own bishops, a request Pope Leo XIV denied.

The group, which has ordained bishops in Écône, Switzerland, on July 1, has been characterized by a desire to restore a perceived past glory of European, white Catholicism. Gibson noted that this mindset, which he termed culturally chauvinistic, contrasts with the global and diverse nature of the Catholic Church, which celebrates mass in various settings worldwide, including refugee camps in Africa.

Gibson explained that the Vatican has historically made concessions to such groups, operating under a "no enemies to the right" approach within the church. However, the SSPX's actions, despite receiving significant accommodation, have been seen as a direct challenge to papal authority.

The dispute extends beyond liturgical practices, such as the Latin Mass, which the SSPX favors and wishes to revisit from before the Vatican II council. The council, which modernized the church in the 1960s, included reforms like lifting anathemas against Protestantism, endorsing religious freedom, accepting the separation of church and state, and revoking condemnations against Jews.

According to Gibson, the underlying issue is a perceived loss of status and privilege, particularly among white European Catholics. This sentiment, he argues, mirrors secular political trends where certain groups feel their traditional position is being eroded. He highlighted that this mentality uses grievances as a wedge issue, pushing for a return to a past era.

While the SSPX is considered an outlier on a global scale, their influence within the United States is noted. The question remains whether this conservative oppositional mentality will persist in the U.S., potentially isolating the American Catholic Church further from the global body. Gibson expressed concern that such a development would be a tragedy, referencing figures like JD Vance who have publicly advised the pope to "stay in his lane" on theological matters. This dynamic, he suggests, underscores the high stakes involved in whether conservative Catholicism will continue to be ascendant within the American church.
