Introduction

In his General Audience on 19 August 2026, Pope Leo XIV reminded the faithful that sacred music is not a decorative extra but an essential prayer of the liturgy. Drawing from chapter six of Sacrosanctum Concilium, he urged composers, choirs, and musicians to know and preserve the musical heritage of the Catholic Church while responsibly embracing new works.

Music as Integral Prayer

The Pontiff explained that singing turns the heart toward God and neighbor, echoing St. Augustine’s insight that “singing belongs to those who love.” Music therefore fosters communion, uniting the assembly in a “tangible manifestation of the Church.” He stressed that each piece must be noble yet simple, of high quality, and easily performed by the whole assembly.

The Role of the Schola

Pope Leo highlighted the importance of the schola cantorum, a choir that traditionally sings in Latin. The schola encourages active participation and ensures that liturgical chant is rendered with dignity. By forming and training scholas in seminaries, schools, and religious houses, the Church safeguards the skill of sacred singing for future generations.

Balancing Tradition and New Compositions

While honoring the ancient principle lex orandi, lex credendi (the law of prayer is the law of faith), the Pope called on composers to let the rich repertoire inspire fresh works. New music must remain rooted in Scripture, liturgical books, and the Church’s spiritual tradition, avoiding “ugliness of style” or “distasteful forms of expression.” This balance allows the liturgy to speak to contemporary sensibilities without losing its sacred character.

Inculturation and Instrumentation

The Pope acknowledged the value of the organ as the Constitution’s preferred instrument, yet he opened the door to other suitable instruments when they edify the worship experience. He also praised the inclusion of local musical traditions, stressing that inculturation should respect both the universal liturgy and the cultural heritage of each people.

Living Heritage in Action

Illustrating the Pope’s call, the Cardinal Domenico Bartolucci Foundation’s ensemble “Sacred Voices” recently toured six U.S. cities, presenting polyphonic works of Palestrina, Perosi, and Bartolucci. Their performances, which include ancient Gregorian chant alongside carefully selected newer pieces, demonstrate how the Church’s musical legacy can travel, inspire, and enrich the faithful worldwide.

Conclusion

Pope Leo XIV’s message is clear: sacred music must remain a living prayer, rooted in the Church’s historic repertoire yet open to authentic, theologically sound innovation. By fostering scholas, respecting liturgical guidelines, and welcoming culturally resonant expressions, composers and musicians can ensure that the Church’s musical heritage continues to lift hearts toward God for generations to come.
