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:

    New Bulletin Article • “21 September 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 21 September 2025) discusses some theological items—supported by certain verses in ancient Catholic hymns—and ends by explaining why certain folks become delirious with jealousy when they observe feats by Monsignor Ronald Knox.

    Cheap! Cheap! Cheap!
    It’s always amusing to see old diocesan newspapers—in huge capital letters—advertising the Cheapest Catholic Paper in the United States. The correspondent who sent this to me added: “I can think of certain composers, published by large companies in our own day, who could truthfully brag about the most tawdry compositions in the world!” I wonder what she could have meant by such a cryptic comment…

    Along with so many others, I have deep respect for Dom Gregory Gregory Murray, who produced this clever harmonization (PDF) of “O SANCTISSIMA.” It’s always amazed me that Dom Gregory—a truly inspired composer—was so confused when it came to GREGORIAN CHANT. Throughout his life, he published contradictory statements, veering back-and-forth like a weather vane. Toward the end of his life, he declared: “I see clearly that the need for reform in liturgical music arose, not in the 18th and 19th centuries, but a thousand years earlier—in the 8th and 9th centuries, or even before that. The abuses began, not with Mozart and Haydn, but with those over-enthusiastic medieval musicians who developed the elaborate and flamboyant Gregorian Chant.”

Quick Thoughts

    Karl Keating • “Canonization Questions”
    We were sent an internet statement (screenshot) that’s garnered significant attention, in which KARL KEATING (founder of Catholic Answers) speaks about whether canonizations are infallible. Mr. Keating seems unaware that canonizations are—in the final analysis—a theological opinion. They are not infallible, as explained in this 2014 article by a priest (with a doctorate in theology) who worked for multiple popes. Mr. Keating says: “I’m unaware of such claims arising from any quarter until several recent popes disliked by these Traditionalists were canonized, including John XXIII, Paul VI, and John Paul II. Usually Paul VI receives the most opprobrium.” Mr. Keating is incorrect; e.g. Father John Vianney, several centuries ago, taught clearly that canonizations are not infallible. Archbishop Fulton J. Sheen would be another example, although clearly much more recent than Saint John Vianney.

    Vatican II Changed Wedding Propers?
    It’s often claimed that the wedding propers were changed after Vatican II. As a matter of fact, that is a false claim. The EDITIO VATICANA propers (Introit: Deus Israel) remained the same after Vatican II. However, a new set of propers (Introit: Ecce Deus) was provided for optional use. The same holds true for the feast of Pope Saint Gregory the Great on 3 September: the 1943 propers (Introit: Si díligis me) were provided for optional use, but the traditional PROPRIA MISSAE (Introit: Sacerdótes Dei) were retained; they weren’t gotten rid of. The Ordo Cantus Missae (1970) makes this crystal clear, as does the Missal itself. There was an effort made in the post-conciliar years to eliminate so-called “Neo-Gregorian” chants, but (contrary to popular belief) most were retained: cf. the feast of Christ the King, the feast of the Immaculate Conception, and so forth.

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

Random Quote

And since it is becoming that holy things be administered in a holy manner, and of all things this sacrifice is the most holy, the Catholic Church, to the end that it might be worthily and reverently offered and received, instituted many centuries ago the holy canon, which is so free from error that it contains nothing that does not in the highest degree savor of a certain holiness and piety and raise up to God the minds of those who offer.

— Council of Trent (1562)
