On Sunday, May 18, 2025, Cardinal Luis Antonio Tagle, a prominent Filipino prelate, participated in the inauguration ceremony of Pope Leo XIV as the 267th pontiff of the Roman Catholic Church. The event took place at St. Peter’s Square in Vatican City, attended by clergy, dignitaries, and faithful from around the world. During the ceremony, Cardinal Tagle placed the Ring of the Fisherman—a traditional symbol of papal authority—on Pope Leo XIV’s finger. The Ring of the Fisherman, also known as the Piscatory Ring, is historically significant as it represents the apostolic succession from Saint Peter, who was a fisherman by trade. The placement of the ring is a key ritual in the formal inauguration of a new pope, signifying the beginning of his papal ministry. Pope Leo XIV thus officially commenced his role as the spiritual leader of the world’s 1.3 billion Catholics. The ceremony was covered by international media and marked a significant moment in the history of the Catholic Church.
