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.”

Theodore Marier Is the Most Important Liturgical Musician—Even Today.

Richard J. Clark · July 26, 2023

BELIEVE that Dr. Theodore Marier is even today the most important liturgical musician in the English Speaking world, despite a life in relative obscurity and service. Few know his name. Yet, his influence and importance certainly surpass postconciliar giants like Richard Proulx and Alexander Peloquin, whose work live on today. And his liturgical works are in greater demand today than when they were composed. My assertion specifies the parameter “most important liturgical musician”—one who worked in a parish with parish choirs in addition to being a composer, scholar, and editor of hymnals. Certainly, Pope Saint Pius X is the most important figure in liturgical music of the Twentieth and Twenty-first Centuries; he is referred to by name twice in SACROSANCTUM CONCILIUM for having “explained more precisely the ministerial function supplied by sacred music in the service of the Lord.” (S. C. §42). Pope Benedict XVI certainly looms as a most prominent figure in the Twenty-first Century. But a liturgical musician working in the trenches to implement Vatican II? Undoubtedly Theodore Marier.

My Presentation • The following presentation was given at the Sacred Music Symposium in California. It was the closing event of a glorious week of sacred music and prayer.

EW KNOW Marier’s work. He was not an international figure as a composer of concert works, although he traveled in circles that included Olivier Messiaen, Jean Langlais, Dom Joseph Gajard of the Solesmes Abbey, Seizi Ozawa, Kurt Masur, and others. His liturgical compositions, influence, and guidance throughout the Twentieth Century and the Conciliar changes are exceedingly important today in the Twenty-first Century especially in light of Pope Francis’ motu proprio, Traditionis custodes. Regardless, his influence stands on its own. Marier is best known as the founder of the Saint Paul’s Choir School (Archdiocesan Choir School) in Cambridge, Massachusetts and as the editor of the landmark hymnal, Hymns Psalms and Spiritual Canticles (1974, 1983) which modeled the sung Mass in the brand new Novus Ordo. His Psalter will be that hymnal’s most lasting contribution. (Listen here to the Boston Cathedral Choir sing Marier’s Psalm 128.) The founding of the school in 1963 (an extraordinary year in the Church!) was to him the natural conclusion of the liturgical documents put forth by Popes Pius X, Pius XI, and Pius XII, and ultimately Vatican II. He took these liturgical directives to heart and acted upon them. He demanded excellence not only from his students, but from the institution he founded.

Marier’s Qualities • His postconciliar liturgical compositions addressed the desperate need for sacred music in the vernacular that was required overnight. His compositions were deeply steeped in Gregorian Chant and demonstrate the continuity of the old rite and the new in a manner that was not only accessible, but beautiful, sacred, and universal. He was the model of a servant leader and servant composer. He spent his life building bridges. He began preparing those bridges in the 1940s with longtime Saint Paul’s pastor, Msgr. Augustine Hickey long before Vatican II. He built bridges during Vatican II (listen here to his Lux Aeterna in English recorded in 1965!) and in the years after Vatican II until his death in 2001. He always built a bridge out of love for God and the faithful. He was a man of deep faith, a loving husband, father, and family man. All of this made him a better liturgical musician.

Personal Takeaway:

I never met Theodore Marier. I did not grow up in New England. However, I have met countless souls whose lives have been changed forever by him. For someone I never met, he has had the most profound influence on my career. Whether one uses his compositions or not—they will have to stand on their own merits—I have one final personal conclusion: The more I learn about Marier, his life and career, the more I am inspired to be a better human being.

Acknowledgments:

This presentation is just a small offering, giving an overview which I hope others can build upon. I wish to extend profuse thanks to Dr. William H. Atwood, Diocesan Director of Music for the Diocese of Bridgeport Connecticut for his dissertation The Influence of Plainchant on the liturgical Music of Theodore Marier. I also wish to thank William Endicott, Class of 2008, for his thesis, Repleatur Os Meum Laude Tua, A History of the Music and Mission of the St. Paul’s Choir School and for supplying recordings and scores. I also wish to thank Br. Paul J. Murray, Class of 1996, for his tireless editorial work on Marier’s compositions. Finally, I wish to thank the late John Dunn (1943-2022), Headmaster & Director of Music Emeritus, Saint Paul’s Choir School for his painstaking editorial updates of Marier’s psalter—a true labor of love—and generous sharing of institutional knowledge.

Soli Deo gloria

Oremus pro invicem.
Let us pray for each other.

    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.

    PDF • “Music List” (Sunday, 28 December)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Feast of the Holy Family of Jesus, Mary, & Joseph (28 Dec. 2025). If such a thing interests you, feel free to download it as a PDF file. The FAUXBOURDON verses for the Communion Antiphon are particularly gorgeous. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • “Music List” (Xmas Midnight Mass)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for Christmas Midnight Mass (“Ad Missam In Nocte”). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is simple, but quite beautiful. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

Quick Thoughts

    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

    What does this mean? “Pre-Urbanite”
    Something informed critics have frequently praised vis-à-vis the Saint Jean de Brébeuf Hymnal is its careful treatment of the ancient hymns vs. the “Urbanite” hymns. This topic I had believed to be fairly well understood—but I was wrong. The reason I thought people knew about it is simple; in the EDITIO VATICANA 1908 Graduale Romanum (as well as the 1913 Liber Antiphonarius) both versions are provided, right next to each other. You can see what I mean by examining this PDF file from the Roman Gradual of 1908. Most people still don’t understand that the Urbanite versions were never adopted by any priests or monks who sang the Divine Office each day. Switching would have required a massive amount of effort and money, because all the books would need to be changed.
    —Jeff Ostrowski
    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

“What really matters in life is that we are loved by Christ and that we love Him in return. In comparison to the love of Jesus, everything else is secondary. And, without the love of Jesus, everything is useless.”
