Who are the ultratraditionalists rebelling against Pope Leo and triggering a rupture with the Vatican?

An ultraconservative Catholic society known as the SSPX (Society of St. Pius) triggered a new schism this week by consecrating four bishops without papal approval, despite Pope Leo XIV’s calls for unity. The ceremony took place Wednesday in Econe, Switzerland, lasting about five hours and attended by roughly 15,000 people, with hundreds of robed priests present and broadcasts worldwide. The Vatican excommunicated six SSPX bishops after the event, according to the report. The new bishops consecrated were Pascal Schreiber (Switzerland), Michael Goldade (United States), Michel Poinsinet de Sivry, and Marc Hanappier (both of France). Bishop Alfonso de Galarreta, consecrated without papal consent in 1988, laid hands on the four. The article frames the action as a direct breach of canon law, carrying automatic excommunication.
