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.”

“O Magnum Mysterium” • Do You Sing This?

Jeff Ostrowski · January 12, 2024

HERE’S A WONDERFUL expression in English: “He can’t see the forest for the trees.” Some—by focusing on details to the exclusion of everything else—end up looking ridiculous. For example, ROBERT F. KENNEDY was born into privilege. When he was a youngster he wanted to “work,” so he got a job delivering newspapers. The only problem is that he used the family chauffeur (!) and Rolls-Royce to deliver the papers. Readers are probably aware that many “trad influencers” often can’t see the forest for the trees when it comes to the sacred liturgy. By spreading false statements about the pre-conciliar liturgy, they often—in my humble opinion—do enormous harm to the so-called TRADITIONAL MOVEMENT. This disturbs me greatly. I believe the Extraordinary Form is extremely important because it emphasizes the continuity of the Catholic Church.

Sacred Liturgy • We sometimes encounter internet folks who insist that “everything before 1954 was absolutely perfect and can’t be improved.” Their minds are made up; it’s pointless to try to persuade them. In reality, however, numerous feasts were added to the liturgical calendar since TRENT which (arguably) should not have been. Especially painful were feasts that “replaced” or “annihilated” feasts whose propers went back at least 1,700 years. One could easily write numerous lengthy dissertations on feasts which have been modified, especially vis-à-vis the seasons of Christmas and Epiphany. Readers can get a ‘hint’ about how complicated these matters are by downloading a special chart created back in 2021.

O MAGNUM MYSTERIUM • The motet “O Magnum Mysterium” by Father Tomás Luis de Victoria (d. 1611) is world famous—and deserves to be. Abbat Joseph Pothier published a plainsong edition in the 1890s. Despite what some claim, this motet is appropriate throughout the season of Epiphany (which originally encompassed the our Savior’s nativity).

Submit Your Version • Do you sing this motet? If so, please send us a recording by your choir and we’ll post it! The following is a ‘live’ recording by my volunteer choir, sung a few weeks ago during Christmas Midnight Mass:

Here’s the direct URL link.

I created individual rehearsal tracks for each voice at #3792.

Season of the Epiphany • The readings after Christmas—that is to say, during EPIPHANYTIDE—talk about the events in the early life of our Lord: the naming of Jesus; His Baptism at the River Jordan; the finding in the temple; the Wedding at Cana; and so forth. The following hymn honors the HOLY NAME of our Savior:

    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.
