(ZENIT News / Vatican City, 05.25.2025).- On the afternoon of Sunday, May 25, Pope Leo XIV presided over the Eucharistic concelebration at the cathedral of the Diocese of Rome, the Basilica of St. John Lateran, on the occasion of his taking possession as Bishop of Rome. As is well known, the Pope is, above all, the Bishop of the Diocese of Rome, although he usually entrusts its administration to his Vicar. The Pope entered through the Holy Door and then began the Mass. At the conclusion, he appeared at the main balcony of the cathedral to greet the faithful gathered in the square. He then traveled by popemobile to the Basilica of St. Mary Major.
We now offer the English text of the homily delivered during the Holy Mass.

***

I offer a cordial greeting to the Cardinals present, and particularly to the Cardinal Vicar, the  auxiliary bishops, all the bishops and the priests – parish priests, parochial vicars and all those who  in in various ways cooperate in the pastoral care of our communities. My greeting also goes to the deacons, the men and women religious, the civil authorities and all of you, the dear lay faithful.

The Church of Rome is heir to a great history, grounded in the witness of Peter, Paul and  countless martyrs, and it has a unique mission, as we see from the inscription on the façade of this  Cathedral: to be Omnium Ecclesiarum Mater, Mother of all the Churches.

Pope Francis frequently encouraged us to reflect on the maternal dimension of the Church (cf.  Evangelii Gaudium, 46-49,139-141; Catechesis, 13 January 2016) and her defining qualities of  tenderness, self-sacrifice and the capacity to listen. Those qualities enable her not only to assist others  but often to anticipate their needs and expectations before they are even expressed. We hope that  those qualities will be increasingly present in the people of God everywhere, including here, in our  great diocesan family: in the faithful, in pastors, and, first of all, in myself. The readings we have  heard can help us to reflect on these qualities.

The Acts of the Apostles (cf. 15:1-2, 22-29) in particular describe how the early Christian  community faced the challenge of opening to the pagan world in its preaching of the Gospel. This  was no easy matter; it called for much patience and mutual listening. This was the case in the  community in Antioch, where the brethren, through dialogue – and even disagreements – resolved  the question together. Paul and Barnabas then went up to Jerusalem. They did not settle the question  on their own: they wanted to be in communion with the Mother Church and so they went there with  humility.

In Jerusalem, they found Peter and the Apostles, who were prepared to listen to them. This  was the beginning of a dialogue that, in the end, led to the right decision. Recognizing the difficulties  of the new converts, they agreed not to impose excessive burdens on them, but rather to insist only  on what was essential (cf. Acts 15:28-29). In this way, what might have seemed a problem became  for everyone an opportunity for reflection and growth.

The biblical text, however, tells us something else, beyond the rich and interesting human  dynamics of the event.

We see this in the words used by the brethren in Jerusalem to communicate their decisions to  those in Antioch. They wrote: “For it has seemed good to the Holy Spirit and to us” (cf. Acts 15:28).  In other words, they emphasized that the most important part of the entire event was listening to  God’s voice, which made everything else possible. In this way, they remind us that communion is  built primarily “on our knees,” through prayer and constant commitment to conversion. For only in  this way can each of us hear within the voice of the Spirit crying out: “Abba! Father!” (Gal 4:6) and  then, as a result, listen to and understand others as our brothers and sisters.

The Gospel reaffirms this point (cf. Jn 14:23-29). It assures us that we are not alone in making  our decisions in life. The Spirit sustains us and shows us the way to follow, “teaching” us and  “reminding” us of all that Jesus said (cf. Jn 14:26).

First, the Spirit teaches us the Lord’s words by impressing them deep within us, written, as  the biblical image would have it, no longer on tablets of stone but in our hearts (cf. Jer 31:33). This  gift helps us grow and become “a letter of Christ” (cf. 2 Cor 3:3) for one another. Naturally, the more  we let ourselves be convinced and transformed by the Gospel — allowing the power of the Spirit to  purify our heart, to make our words straightforward, our desires honest and clear, and our actions  generous — the more capable we are of proclaiming its message.

Here, the other verb comes into play: we remember, that is, we reflect in our hearts upon what  we have experienced and learned, in order to understand more fully its meaning and to savour its  beauty.

I think in this regard of the challenging process of listening that the Diocese of Rome has  undertaken in these years, a process carried out at various levels: listening to the world around us to  respond to its challenges, and listening within our communities to understand needs and to propose  sage and prophetic initiatives of evangelization and charity. This has been a challenging, ongoing  journey meant to embrace a very rich and complex reality. Yet it is worthy of the history of this local  Church, which has shown, time and again, that it is able to “think big”, unafraid to embark on bold  projects and to confront new and challenging scenarios.

This is evident in the great efforts and many initiatives that the Diocese has made to welcome  and provide for the needs of pilgrims during the present Jubilee. Thank you! These have made the  city of Rome appear to visitors, some of whom have travelled from far away, as a wide, open and  welcoming home, and above all as a place of deep faith.

For my part, I would like to express my firm desire to contribute to this great ongoing process  by listening to everyone as much as possible, in order to learn, understand and decide things together,  as Saint Augustine would say, “as a Christian with you and a Bishop for you” (cf. Serm. 340, 1). I  would also ask you to support me in prayer and charity, mindful of the words of Saint Leo the Great:  “All the good we do in the exercise of our ministry is the work of Christ and not our own, for we can  do nothing without him. Yet we glory in him, from whom all the effectiveness of our work is derived”  (Serm. 5, De Natali Ipsius, 4).

Let me conclude by adding the words with which Blessed John Paul I, whose joyful and serene  face had already earned him the nickname of “the smiling Pope,” greeted his new diocesan family on  23 September 1978. “Saint Pius X,” he said, “upon entering Venice as patriarch, exclaimed in Saint  Mark’s: ‘What would become of me, dear Venetians, if I did not love you?’ I would say something  similar to you Romans: I assure you that I love you, that I desire only to enter into your service and  to place my own poor abilities, the little I have and am, at the service of all” (Homily for the Taking  of Possession of the Chair of the Bishop of Rome).

I too express my affection for you and my desire to share with you, on our journey together,  our joys and sorrows, our struggles and hopes. I too offer you “the little I have and am,” entrusting  it to the intercession of Saints Peter and Paul and of all those other brothers and sisters of ours whose  holiness has illuminated the history of this Church and the streets of this city. May the Virgin Mary  accompany us and intercede for us.
