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.”

“Theology of Worship” • Msgr. Robert Skeris (1998)

Jeff Ostrowski · February 18, 2025

NYONE WHO HAS studied Catholic sacred music over the last sixty years will know the name of Monsignor Robert Alex Skeris. Some knew him as a professor at the Catholic University of America. Others knew him when he was head of the Theology department at Christendom college. In the CMAA journals, Msgr. Schuler often referenced “Father Skeris of Rome” since he ran the Pontifical Institute of Sacred Music during the 1980s. I was present when Monsignor Skeris gave a lecture to the Sacred Music Colloquium—which he helped found 60 years ago—and received a standing ovation from a packed auditorium. The audience just kept applauding for the longest time…to the point where my ears started to hurt!

A student of Monsignor Skeris sent me a marvelous interview from 7 January 1998. In it, Mother Angelica of EWTN asks Monsignor Skeris to explain the Theology of worship. This excerpt addresses participatio actuosa (“active participation”):

Mother Angelica asks why liturgical music must be sacred:

Monsignor Skeris mentions what the fathers of Vatican II actually voted upon regarding Latin in the liturgy:

The Full Video • You can obtain this 60-minute DVD by searching Google. I think it was in the range of $17.00, and you’ll enjoy hearing Monsignor Skeris give candid answers to excellent questions from the audience. He speaks about the relationship of text & music; why Gregorian chant is the Church’s preference; whether we can use orchestral Masses based on secular tunes; and numerous other topics. I like the part where Mother Angelica presses him to reveal his favorite piece of music! By the way, EWTN has posted a 1990 article by Monsignor Skeris:

If you doubt the importance of discussions by the fathers of Vatican II, read this 1976 reference to the Conciliar relationes.

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”

    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.

Random Quote

When Christ gave the bread, he did not say, “This is the symbol of my body,” but, “This is my body.” In the same way, when he gave the cup of his blood he did not say, “This is the symbol of my blood,” but, “This is my blood.”

— Theodore, Bishop of Mopsuestia, writing in the 5th Century
