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:

President’s Corner

    “Offertory” at Catholic Funerals
    I have argued that the OFFERTORY—at least in its ancient form—is more of a responsory than an antiphon. The 1962 Missal specifically calls it “Antiphona ad Offertorium.” From now on, I plan to use this beautiful setting (PDF) at funerals, since it cleverly inserts themes from the absolution of the body. Tons more research needs to be done on the OFFERTORY, which often is a ‘patchwork’ stitching together various beginnings and endings of biblical verses. For instance, if you examine the ancient verses for Dómine, vivífica me (30th Sunday in Ordinary Time) you’ll discover this being done in a most perplexing way. Rebecca Maloy published a very expensive book on the OFFERTORY, but it was a disappointment. Indeed, I can’t think of a single valuable insight contained in her book. What a missed opportunity!

    “In Paradisum” • Gregorian Chant
    As a RECESSIONAL on All Souls’ Day (November 2nd), we will sing In Paradísum Dedúcant Te Ángeli (PDF). When it comes to Gregorian Chant, this is one of the most popular “songs.” Frankly, all the prayers and chants from the traditional REQUIEM MASS (Missa exsequialis or Missa pro defunctis) are incredibly powerful and never should’ve been scuttled. Click here to hear “In Paradisum” in a recording I made this afternoon. Professor Louis Bouyer spoke of the way Bugnini “scuttled the office of the dead” in this fascinating excerpt from his memoirs. In his book, La riforma litugica (1983), Bugnini bragged—in quite a shameful way—about eliminating the ancient funeral texts, and even admitted those venerable texts were “beloved” (his word) by Catholics.

    “Music List” • All Souls (2 November)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 2 November 2025, which is the Commemoration of All the Faithful Departed (“All Souls”). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the top-notch feasts website alongside the official texts in Latin. In my humble opinion, it’s weird to have the feast of All Saints on a Sunday. No wonder the close associate of Pope Saint Paul VI said the revised KALENDAR was “the handiwork of a trio of maniacs.” However, I can’t deny that sometimes the sacred liturgy consists of elements that are seemingly contradictory: e.g. the Mode 7 “De Profúndis” ALLELUIA, or the Mode 8 “Dulce lignum” ALLELUIA on the various ancient feasts of the Holy Cross (3 May, 14 September, and so on).

Quick Thoughts

    Gospel Options for 2 November (“All Souls”)
    We’ve been told some bishops are suppressing the TLM because of “unity.” But is unity truly found in the MISSALE RECENS? For instance, on All Souls (2 November), any of these Gospel readings may be chosen, for any reason (or for no reason at all). The same is true of the Propria Missæ and other readings—there are countless options in the ORDINARY FORM. In other words, no matter which OF parish you attend on 2 November, you’ll almost certainly hear different propers and readings, to say nothing of different ‘styles’ of music. Where is the “unity” in all this? Indeed, the Second Vatican Council solemnly declared: “Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community.”

    “Our Father” • Musical Setting?
    Looking through a Roman Catholic Hymnal published in 1859 by Father Guido Maria Dreves (d. 1909), I stumbled upon this very beautiful tune (PDF file). I feel it would be absolutely perfect to set the “Our Father” in German to music. Thoughts?

    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.

Random Quote

Jeffrey Tucker: “What are your thoughts on what passes for sacred music in most Catholic parishes today?” Richard Morris: “There’s nothing sacred about it. The tunes, rhythms, and messages are drawn mainly from secular culture. When it isn’t aesthetically repugnant and downright offensive to the Faith, it is utterly forgettable.”

— James Richard Morris (concert organist)
