The Vatican’s official Jubilee 2025 calendar is currently listing a pilgrimage by the Priestly Fraternity of Saint Pius X (SSPX), with the occasion marking a rare moment of visible accord following long-running tensions between SSPX and the Vatican.

According to the SSPX website for Great Britain, the pilgrimage on 21 August will include a public Rosary at Colle Oppio, a Solemn High Mass at 9.30 a.m., and a procession entering the Holy Door of the Archbasilica of St John Lateran.

The SSPX, founded by Archbishop Marcel Lefebvre in November 1970 in Switzerland, operates with a mission to preserve the Traditional Latin Mass and pre-Vatican II liturgy, which includes training priests committed to tradition and what the organisation describes as the "Mass of All Time".
