Vatican issues guidelines for Catholics leaving the Society of Saint Pius X to regain full communion

The Vatican has published clear instructions for individuals who wish to leave the Society of Saint Pius X (FSSPX) and return to full communion with the Catholic Church. The document details the steps required for priests, including finding a diocesan bishop to receive them, sending a personal letter to the Pope, providing proof of ordination, signing a profession of faith and a formula of adhesion, pledging loyalty to the Pope, accepting Church teaching and the Novus Ordo liturgy, and undergoing a trial period of one to three years. For lay faithful, the process involves formally declaring the Catholic faith, publicly acknowledging obedience to the Pope and the local bishop, and submitting a signed declaration of faith and adhesion. The guidelines note that anyone attending FSSPX Masses incurs excommunication, but those who participated solely for liturgical reasons are not culpable if they cease attendance and consult their local pastor. A related commentary criticizes the Vatican’s stance, highlighting that the excommunication extends to both priests and lay members and pointing out ambiguities in the requirements for returning members, especially in Poland where the FSSPX has a substantial presence.
