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.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    PDF Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

Quick Thoughts

    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

“Our Christian people regard with great joy everything that contributes to the splendor of the ceremonies. Jesus—who was poor in His private life—received ointment on His feet. See Thomas Aquinas (Prima Secundae, q. 102, art. 5, ad 10) and the holy Curé of Ars. The Church has always loved beautiful churches, and so forth. We must preserve our sacred patrimony and make sure sacred objects do not become secular possessions.”

— Abbot & Council Father denouncing “noble simplicity” during Vatican II
