A Papacy Begins: Pope Leo XIV Calls for United Church at His Inauguration Eucharistic Celebration

Reflecting on the qualities expected in the successor of St. Peter, he said: “If the rock is Christ, Peter must shepherd the flock without ever yielding to the temptation to be an autocrat, lording it over those entrusted to him.”

Hundreds of religious and international leaders and dignitaries, representing nearly 200 foreign delegations, attended the Mass for the Beginning of the Petrine Ministry of the Bishop of Rome on May 18, including U.S. Vice President JD Vance and U.S. Secretary of State Marco Rubio. 

In his homily, Leo spoke about the conclave that chose him to be the Church’s 267th pope: “Coming from different backgrounds and experiences, we [the cardinal electors] placed in God’s hands our desire to elect the new successor of Peter, the bishop of Rome, a shepherd capable of preserving the rich heritage of the Christian faith and, at the same time, looking to the future, in order to confront the questions, concerns, and challenges of today’s world.”

“Love and unity: These are the two dimensions of the mission entrusted to Peter by Jesus,” the pontiff added.

Quoting St. Augustine — who inspired the religious Order of St. Augustine, to which he belongs — Pope Leo XIV said: “The Church consists of all those who are in harmony with their brothers and sisters and who love their neighbor.”

The pope lamented the discord and wounds of our time: “For our part, we want to be a small leaven of unity, communion, and fraternity within the world.”

Before delivering his homily, Leo received the symbols of the papacy, the pallium and the fisherman’s ring, in a richly-symbolic rite including an act of obedience and fidelity from representatives of the College of Cardinals and “the people of God.”

The pallium, a narrow band made of white lamb’s wool, was draped over his shoulders. The pallium, which has two black flaps and three pins representing the nails of Christ’s cross, symbolizes the bishop as the good shepherd and Christ the Lamb crucified for the salvation of the human race.

The gold fisherman’s ring, a part of the papal insignia since the first millennium, has the image of St. Peter with the keys and fisherman’s net, a symbol of authority and the duty entrusted to St. Peter by Jesus to be “a fisher of men.”

After the sung proclamation of the Gospel in Latin and Greek — the passage from the Gospel of John, when Jesus asks Peter “do you love me?” and commands him to “feed my lambs” and “tend my sheep” — Cardinal Dominique Mamberti placed the pallium around Leo’s shoulders and Cardinal Fridolin Ambongo Besungu, OFM Cap, recited a prayer.

With visible emotion, Leo received the fisherman’s ring from Cardinal Luis Tagle, looking at the ring and then lifting his face in prayer.

His papal name and elements from his coat of arms — the fleur-de-lis, a symbol of purity and the Virgin Mary, and a pierced heart, the traditional symbol of the Augustinian order — are engraved on the inside of the ring.

Before the Mass, Pope Leo XIV took his first ride in the popemobile, standing and waving to the crowds gathered in St. Peter’s Square and Via Conciliazione, the main thoroughfare to the Vatican basilica.

The rite for the beginning of the pontificate started with Leo praying at the tomb of St. Peter together with the cardinals, who then walk in solemn procession together through St. Peter’s Basilica to St. Peter’s Square. 

An image of our Mother of Good Counsel from the Italian Sanctuary of Genazzano, which Leo visited on May 10 in one of his first acts as pope, was placed to the left of the altar.

“This is the hour for love!” Pope Leo said in his homily. “The heart of the Gospel is the love of God that makes us brothers and sisters. With my predecessor Leo XIII, we can ask ourselves today: If this criterion ‘were to prevail in the world, would not every conflict cease and peace return?’ (Rerum Novarum, 21).”

“With the light and the strength of the Holy Spirit, let us build a Church founded on God’s love,” he continued, “a sign of unity, a missionary Church that opens its arms to the world, proclaims the word, allows itself to be made ‘restless’ by history, and becomes a leaven of harmony for humanity.”

At the end of Mass, Leo appealed for “a just and lasting peace” around the world, especially in Gaza, Myanmar, and Ukraine, and sang the Regina Caeli, a Marian antiphon for the Easter season.

In addition to international leaders and dignitaries, a large number of religious representatives attended the first papal Mass, including members of the Muslim, Hindu, Buddhist, Sikh, Zoroastrianism, and Jainism religions.

Around 36 different Christian churches or organizations were also represented, with Ecumenical Patriarch Bartholomew I of Constantinople and Patriarch Theophilos III of the Greek Orthodox Church of Jerusalem in attendance.

Jewish leaders from Italy, Israel, and the United States also came to the Mass, including the head rabbi of Rome, Riccardo Di Segni.
