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.”

“Unsolved Mysteries” • What Happened To This Institute?

Jeff Ostrowski · October 11, 2024

HE IMPRESSIVE collection of vernacular plainsong propers known as The O’Fallon Propers was published in the 1960s by SAINT MARY’S INSTITUTE in O’Fallon, Missouri. But what exactly was “SAINT MARY’S INSTITUTE”—and who was in charge of it? From what I can tell, the motherhouse for the Sisters of the Most Precious Blood was located in O’Fallon (just west of St. Louis, Missouri). The SAINT MARY’S INSTITUTE seems to have been intimately connected with Dom Ermin Vitry, OSB, who was born on 22 December 1884 in Lobbes, a village in Belgium. Vitry entered religious life at the magnificent Maredsous Abbey in 1902, one year before the sacred music legislation of Pope Saint Pius X was issued in 1903.1

Dom Ermin Vitry • Dom Ermin Vitry was ordained a Benedictine priest in 1907. At the LEMMENSINSTITUUT, he studied organ with the legendary Edgar Tinel (d. 1912). The Benedictines sent him from Belgium to the United States where he served as director of music for the SAINT MARY’S INSTITUTE—but sources disagree vis-à-vis the precise years this took place. For the record, Monsignor Martin B. Hellriegel served as chaplain for the O’Fallon sisters from 1918-1940. Vitry and Hellriegel knew each other.

The Institute • One source says: “As choir director, Dom Ermin taught the Sisters an appreciation of sacred liturgical music through Gregorian Chant.” In a (very brief) biography of Dom Vitry published in 1988, Monsignor Francis P. Schmitt insinuates that Vitry was the driving force behind what would become the O’Fallon Propers. Monsignor Schmitt wrote: “I am no enthusiast for English chant, never have been. But I recognize a legitimate place for it…” He then went on to say:

“The late Dom Ermin Vitry and the recently deceased Charles Dreisoerner (either of whom forgot more about Gregorian than most pundits I encounter these days will ever know) both felt that, in some measure, the preservation of Gregorian as the song of the faithful, the saving of it from a second and final death, depended upon a viable vernacular use.”

Mysterious • Some people believe that Monsignor Hellriegel was the actual composer of The O’Fallon Propers. One thing is certain: its 483 pages must have been in production for many years before its publication in 1964. I would welcome any information about what remains of SAINT MARY’S INSTITUTE or the Sisters of the Most Precious Blood in O’Fallon.

Here’s a photograph of Dom Ermin Vitry taken circa 1935:

1 This motu proprio was known as “Inter Pastoralis Officii Sollicitudines.” Some people also refer to it by the Italian name: “Tra Le Sollecitudini.”

    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

“A striking detail: at Solesmes, we remember hearing Justine Ward criticize accompaniment sometimes or seeing her cover her ears, especially when the organ accompanied a soloist, which is something she could not accept.”

— Dom Pierre Combe
