When Music Becomes Prayer: Leo XIV Unveils the Power of Song in the Liturgy and Peace
In his catechesis on the Second Vatican Council, the Pope affirms sacred music as an essential part of worship, quotes St. Augustine to remind us that “singing is proper to those who love,” and calls for building a “civilization of love” in the face of the world’s divisions
Far from being a mere aesthetic backdrop or a circumstantial embellishment, sacred music is an essential driving force of the liturgical encounter and communal communion. Pope Leo XIV emphasized this during the General Audience held in St. Peter’s Basilica, dedicating his catechesis to a deeper understanding of Chapter VI of the Second Vatican Council’s Constitution Sacrosanctum Concilium .
Before thousands of pilgrims of various nationalities, the Holy Father delved into the ministerial dimension of sacred song, a tradition that the conciliar document itself defines as a “treasure of inestimable value.” Citing the famous principle of St. Augustine, “Cantare amantis est” (“to sing is proper to one who loves”), Leo XIV emphasized that music expresses the affections of the believing heart, opening the soul to divine grace and shaping lived faith.
The function of music: from harmony to communion
“In the liturgy, singing and playing music means praying, attuning one’s heart to the hearts of our brothers and sisters and to God,” the Pope affirmed. Music in celebrations is not merely for entertainment or simply following fleeting trends, but rather acts as a true “epiphany of the Church”: a concrete manifestation of spiritual unity that transcends individual differences.
To safeguard the dignity of worship, the Pope recalled the fundamental criteria established by Vatican II and Church tradition:
- Fidelity to the Lex orandi, lex credendi : The texts must be inspired primarily by Sacred Scripture and liturgical sources, ensuring that the sung prayer reflects the truth of the faith.
- Quality and simplicity: The melodies should be noble but accessible, facilitating the active participation of the entire assembly.
- Preeminence of Gregorian chant and the organ: Without excluding other instruments and genres that fit with the dignity of the temple, the Pope highlighted the value of the Gregorian heritage and the sound of the organ.
- Careful inculturation: The integration of musical traditions from different peoples was encouraged, educating the religious sense without falling into careless or inappropriate expressions of the mystery being celebrated.
Education, awareness and the search for peace
A central point of the catechesis was the urgent need to foster musical and liturgical formation in seminaries, novitiates, and communities. Leo XIV appealed to composers, members of scholae cantorum , and ministers to cultivate a rigorous care that would purify sacred music of any stylistic shortcomings or negligence.
Concluding with words from St. Ignatius of Antioch, the Pope invited the faithful to “become a choir” to sing with one voice the love of the Father. This message of inner harmony also resonated in his remarks to the various language groups present, where the Pope called for cultivating a peaceful conscience and actively working to build the “civilization of love,” recalling the witnesses of faith who, throughout history, have given their lives for concord and forgiveness.

Catechesis. The Documents of the Second Vatican Council. III. Constitution Sacrosanctum Concilium. 7. Sacred Music
Dear brothers and sisters,
The sixth chapter of the Constitution Sacrosanctum Concilium (SC) of the Second Vatican Council is dedicated to sacred music. The document states that “The musical tradition of the universal Church is a treasure of inestimable value, greater even than that of any other art. The main reason for this pre-eminence is that, as sacred song united to the words, it forms a necessary or integral part of the solemn liturgy.” (SC, 112). It specifies that “Sacred music is to be considered the more holy in proportion as it is more closely connected with the liturgical action, whether it adds delight to prayer, fosters unity of minds, or confers greater solemnity upon the sacred rites. But the Church approves of all forms of true art having the needed qualities, and admits them into divine worship.” (ibid.).
Here we find the core of the Council’s teaching, which confirms and deepens the ministerial function of music in the liturgy, which had already been highlighted by Saint Pius X in the Motu Proprio Inter sollicitudines (22 November 1903). Music, indeed, is part of the liturgical action and is not merely a decorative part of the celebration. In the liturgy, to sing and to play music means to pray, attuning one’s heart to that of our sisters and brothers and to God, through active participation in the mystery that is being celebrated. In particular, music expresses the affective dimension of prayer, as Saint Augustine says: “Cantare amantis est”, that is, “singing belongs to those who love” (Sermo 336, 1). This is very important, because it helps us to open our hearts to God’s action in grace and to allow ourselves to be moulded by it.
Singing also fosters communion. It contributes to the unity of hearts, overcoming differences between people and bringing everyone together in praise of God through the symphony of voices. Thus, it becomes an epiphany of the Church, a tangible manifestation of the communion that belongs to her very nature.
Certain requirements arise from the profound theological significance of sacred song as an integral part of the liturgical action. The first is that it must respond at every level to what is most appropriate for the liturgical moment, beyond fashions or the particular sensitivities of composers. Its form, especially in its melodic aspect, must be at once noble and simple, of high musical quality and easily performable, particularly when it is intended to be sung by the whole assembly (cf. SC, 121).
For the same reason, the Council recommends that the texts too should be suitable, profound and at the same time readily understandable, inspired mainly by Sacred Scripture, the liturgical books and the spiritual Tradition of the Church. Attention must be paid to this, so that the dynamic expressed in the ancient principle lex orandi, lex credendi, that is, the law of prayer is also the law of faith, may remain alive and continue to grow.
Sacrosanctum Concilium devotes considerable attention to the theme of the active participation of the faithful (cf. no. 114). This “must be understood […] on the basis of a greater awareness of the mystery being celebrated and its relationship to daily life” (Benedict XVI, Apostolic Exhortation Sacramentum caritatis, 52), in a “spirit of constant conversion which must mark the lives of all the faithful” (ibid., 55). As for the concrete way in which this can be achieved through the specific role of sacred music, the Constitution offers a clear answer: “the people should be encouraged to take part by means of acclamations, responses, psalmody, antiphons, and songs” and “reverent silence” should be fostered (SC, 30). It urges each person, minister or member of the faithful, to perform “all of, but only, those parts which pertain to his office by the nature of the rite and the principles of liturgy” (SC, 28), in the harmonious balance between the different ministries, the various interventions and moments of silence.
The Council then attributes great value to Gregorian chant, without excluding other genres of sacred music from the celebration. Particular attention is also given to the organ (cf. SC, 120), while the use of other instruments is permitted “on condition that the instruments are suitable, or can be made suitable, for sacred use, accord with the dignity of the temple, and truly contribute to the edification of the faithful” (SC, 120).
A theme close to the Council’s reform is that of inculturation, including in the field of sacred music. In particular, with regard to the musical traditions of different cultures, the Council emphasizes the importance of taking them seriously into consideration, as they form part of people’s religious and social life. Therefore, on the one hand, an “attitude toward religion” should be promoted in everyone (SC, 119). On the other hand, as far as may be practicable […] every effort should be made to see that the traditional music of these peoples, both in schools and in sacred services may be promoted (cf. ibid.).
A particular role in the liturgical context is given to the schola cantorum. The Council recommends the promotion of this pastoral instrument, to ensure the “proper performance of the parts which belong to it, according to the different kinds of music sung, and to encourage the active participation of the faithful in the singing” (Sacred Congregation of Rites, Instruction Musicam sacram, 19).
For this reason, the composer of sacred music is called to know and preserve the musical heritage of the Church, allowing it to inspire new compositions at the service of the liturgy, while respecting contemporary sensibilities and the different cultural traditions, so as “‘purify worship from ugliness of style, from distasteful forms of expression, from uninspired musical texts which are not worthy of the great act that is being celebrated’, to guarantee dignity and excellence to liturgical compositions” (Saint John Paul II, Chirograph on Sacred Music, 22 November 2003, 3).
For all these reasons, the Council Fathers recommend promoting the formation and practice of sacred music “in seminaries, in the novitiates and houses of study of religious of both sexes, and also in other Catholic institutions and schools” (SC, 115), and ensuring that musicians and singers receive sound liturgical formation (cf. ibid.).
Dear brothers and sisters, the Fathers of the Church held liturgical singing in great esteem as a symbol of ecclesial communion. We can therefore conclude with these beautiful words of Saint Ignatius of Antioch: “Let each of you unite to become a choir, so that, harmonious in love and taking up the song of God in unison, you may sing with one voice through Jesus Christ to the Father, so that he may hear you and recognize, from the good works you perform, that you are members of his Son” (cf. Letter to the Ephesians, 4, 2).

Summary of the Holy Father’s words:
Dear brothers and sisters, in our continuing catechesis on the Second Vatican Council’s Constitution on the Sacred Liturgy, Sacrosanctum Concilium, today we consider the importance of sacred music. Indeed, singing and playing a musical instrument are acts of prayer. Music thus fosters our unity in praising God and opens our hearts to be fashioned by his grace. Far from being merely decorative, therefore, sacred music is a treasure of profound value. It should always be dignified, draw inspiration from Sacred Scripture and reflect the grandeur of the mystery celebrated. Sacred music is also to reflect local cultures, expressing the authentic traditions of peoples, while promoting the universal Church’s musical heritage. The Council also emphasized the need for solid liturgical formation and education in sacred music. Dear brothers and sisters, in the liturgy, may we join together in love, and – in the words of Saint Ignatius of Antioch – “with one voice sing to the Father through Jesus Christ.”
