Corpus Christi Watershed

Pope Saint Paul VI (3 April 1969): “Although the text of the Roman Gradual—at least that which concerns the singing—has not been changed, the Entrance antiphons and Communions antiphons have been revised for Masses without singing.”

Frank La Rocca • Contemporary Music for the Sacred Treasury

Richard J. Clark · August 28, 2015

SACRED BANQUET! The Eucharist gives us food for a difficult journey. Appropriately, the Mass is our greatest prayer. It is in a way, a rehearsal for our life in heaven. The chant Ave Verum describes Jesus’ body as “a foretaste (of heaven) in the trial of death.” The Mass is nothing less than this. But we are human and we fall short. Faith and reliance upon God must bridge our failings.

As such, music for the Sacred Liturgy must trend toward the transcendent—holy, beautiful, and universal. What it is not called to do is to please anyone other than God. This is a very tall order. Once again, our frail humanity is a frequent obstacle to such ideals. Again, we must rely upon God and the gift of the sacrament of Himself–the Eucharist.

But there are many gems that area beautiful, sacred, and universal. It is our sacred treasury of music, given highest value by Vatican II: “The musical tradition of the universal Church is a treasure of inestimable value, greater even than that of any other art…”(Constitution on the Sacred Liturgy, §112.) Occasionally, there are gems added to this sacred treasury.

F YOU ARE NOT FAMILIAR with the works of composer Frank La Rocca, you should be. His transcendent setting of O Sacrum Convivum is rooted in traditional polyphony, yet is thoroughly modern at every turn. The harmony is modal yet often very accessible to the contemporary modern ear. At other times, the harmonic language is defiant of traditional harmony in the vein of progressive works of the Twentieth and Twenty-first Centuries.

Through it all La Rocca achieves symmetry and wholeness and therefore holiness. It depicts the eternal Eucharist, while simultaneously addressing and calming the anxieties, evils, and depression of modern life. He paints the text beautifully, ultimately filling a besieged world with the hope promised by the Sacred Banquet.

A work such as this moves contemporary sacred music towards the realization of Vatican II. It represents an ideal not because of style or preference but because of transcendence and significance. Anchored in tradition, it speaks with the authority of the ages yet with the innovation of modernity. Imbued with the Spirit, it is timeless.

O Sacrum Convivium
text: St. Thomas Aquinas (1225-1274)

O sacred banquet!
in which Christ is received,
the memory of his Passion is renewed,
the mind is filled with grace,
and a pledge of future glory to us is given.

    Pipe Organ “Answers” in Plainsong?
    In 2003, I copied a book by Félix Bélédin (d. 1895), who was titular organist—from 1841 to 1874—at the Cathedral of Saint John the Baptist in Lyon (France). In 2008, we scanned and uploaded the book to the Lalande Online Library. Nobody knows for sure when the book was published; some believe it first appeared in the 1840s. In any event, one who examines this excerpt, showing GLORIA IX might wonder why it says the organ answers in plainsong. However, the front of the book explains, telling the organist explicitly when to “respond in plainchant.” This is something called organ alternatim. Believe it or not, the pipe organ would take turns with the choir, playing certain texts instrumentally instead of having them sung. I’m not very well-versed in this—pardon the pun—but if memory serves, ORGAN ALTERNATIM was frowned upon by the time of Pope Saint Pius X. Nevertheless, French organists kept doing it, even after it was explicitly condemned as an abuse.

    Music List • (5th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 5th Sunday of Lent (22 March 2026). If such a thing interests you, feel free to download it as a PDF file. Traditionally, this Sunday was called ‘Passion’ Sunday. Starting in 1956, certain church leaders attempted rename both ‘Passion’ Sunday and ‘Palm’ Sunday—but it didn’t work. For example, Monsignor Frederick McManus tried to get people to call PALM SUNDAY “Second Passion Sunday”—but the faithful rejected that. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Music List • (Holy Thursday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Holy Thursday, which is 2 April 2026. If such a thing interests you, feel free to download it as a PDF file. I’m not sure I’ve ever heard a more piercingly beautiful INTROIT, and I have come to absolutely love the SATB version of ‘Ubi cáritas’ we are singing (joined by our burgeoning children’s choir). I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.

Random Quote

“We cannot approve of the attitude of those who use the problems raised and discussed by the Council to create in themselves and in others an attitude of unrest and a desire for radical reformation, as if the Council gives every private opinion a chance to destroy the heritage of the Church. acquired during Her many centuries of history and experience.”

— Pope Paul VI (30 June 1965)
