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.”

    “Entrance Chant” • 23rd (Ordinary Time)
    This coming Sunday, 7 September 2025, is the 23rd Sunday in Ordinary Time (Year C). You can download the “Entrance Chant,” conveniently located at the feasts website. I also recorded a rehearsal video for it (freely available at the same website). The Communion Chant includes gorgeous verses in FAUXBOURDON. I attempted to create a rehearsal video for it, and it’s been posted at the feasts website, called by some: “church music’s best kept secret.”

    PDF Download • 3 September
    According to the MISSALE RECENS, the Feast of Saint Gregory the Great occurs on 3 September (the date Gregory became pope). Formerly, his feast was celebrated during Lent, on 12 March (the day Gregory died). In Latin, the feast is: Die 3 Septembris: S. Gregorii Magni, papæ et Ecclesiæ doctoris. you can download the Latin Introit, the Latin Offertory, as well as the Communion with gorgeous fauxbordon in English. Abbat Joseph Pothier—along with Dom André Mocquereau, Bishop Laurent Janssens, Father De Santi, and other Gregorian superstars—sang with a choir of 1,210 voices (from 36 different Roman colleges) under the direction of Monsignor Antonio Rella. That Mass included the “Alma cohors,” a special SEQUENCE for Saint Gregory…much to the dismay of those who believe in strict adherence to rubrics. The Mass on 11 April 1904 was celebrated by Pope Saint Pius X, at the great GREGORIAN CONGRESS held in Rome “to mark the 13th Centenary of the death of Saint Gregory the Great.” Someday, there’s much I’d love to say about this congress. We even have recordings (!) from it (made in 1904 by the Gramophone Company) with choirs conducted by Dom Pothier, Dom Mocquereau, Dom Janssens, Monsignor Rella, Baron Kanzler, and others.

    New Bulletin Article • “7 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 is called: “Professor Bouyer’s Regret.”

Quick Thoughts

    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).

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.
