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.”

“This Change Blew My Mind” • Confusion: Is 9 December 2024 a Holy Day of Obligation?

Jeff Ostrowski · October 15, 2024

JUST GOT OFF the telephone with someone who works closely with the USSCB’s “Canonical Affairs Committee” as well as the USCCB’s “Committee on Divine Worship.” Over the telephone, he confirmed something that’s quite surprising—at least to me. A change was made by the USCCB a few days ago. This year, the feast of the IMMACULATE CONCEPTION falls on a Sunday. Normally, that feast would be “bumped” or “moved” or “transferred” to the next day (9 December) and the obligation to assist at Mass and refrain from unnecessary servile work would not be transferred. But this has been changed. The USCCB website currently has information that—as of a few days ago—has been superseded:

Surprising Modification • A few days ago—and nobody seems quite certain of the precise day—the USCCB made a change. A notice has appeared on a special website only accessible by the bishops. This alteration by the USCCB seems to have been the result of an inquiry sent by Bishop Thomas Paprocki of the Diocese of Springfield, Illinois. Below is what the Vatican wrote:

*  PDF Download • Vatican Letter to Bishop Paprocki (Springfield, IL)

The Results • Because of this modification, the obligation to assist at Mass and refrain from unnecessary servile work will be transferred in 2024—along with the feast of the IMMACULATE CONCEPTION—to Monday, 9 December 2024. If memory serves, bishops have the authority to dispense people from holy days of obligation. Therefore, I urge readers to investigate the situation in their own dioceses.

(1 of 2) Random Thoughts • I doubt anyone’s interested in my opinion about these matters. However, it’s peculiar to see Bishop Paprocki writing to the Vatican vis-à-vis USA holy days of obligation. After all, the bishops of each country—not Vatican bureaucrats—decide which holy days of obligation are to be observed in their territories. For example, the feast of the EPIPHANY (a cardinal feast) is a holy day of obligation in many countries, but I don’t believe it’s ever been a holy day of obligation in the United States.

(2 of 2) Random Thoughts • According to the liturgical calendar of 1962, the feast of the IMMACULATE CONCEPTION “replaces” or “supplants” or “annihilates” the 2nd Sunday of Advent when it falls on a Sunday. But those who attend Mass in the Extraordinary Form are bound by the current Code of Canon Law—not some previous code of Canon Law. That means those who attend EF Masses are obligated to assist at Mass and refrain from unnecessary servile work on 9 December 2024, which is “Monday in the 2nd Week of Advent” according to the 1962 calendar. Most priests who celebrate Mass according to the 1962 MISSALE ROMANUM will probably not celebrate the feast of the IMMACULATE CONCEPTION on 9 December, although (in my humble opinion) that would make the most sense. I suppose somebody could say: “But that’s not traditional, Jeff, and we adhere to the tradition.” The problem is, I could name tons of instances in which TLM priests do not adhere to “tradition.” For example, offering Mass in the evening is not traditional. Neither is it “traditional” to distribute Holy Communion to the congregation during Solemn Mass, which we have discussed many times. But I digress…

Mind Blown! • For what it’s worth, the USCCB expert told me over the telephone that this modification—especially being made at such a late date—literally blew his mind. There’s already great confusion regarding holy days of obligation, especially with the whole “MONDAY-SATURDAY” business. Some Catholics find it bizarre that the feast of the IMMACULATE CONCEPTION is not important enough to supplant a Sunday in Advent (as it does in the EF), yet it is important enough for its obligation to be “transferred.”

Again, I urge each reader
to research the situation
regarding 9 December 2024
in your particular territory.

    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.

    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.

Random Quote

“The main place should be given, all things being equal, to gregorian chant, as being proper to the roman Liturgy. Other kinds of sacred music, in particular polyphony, are in no way excluded, provided that they correspond to the spirit of the liturgical action and that they foster the participation of all the faithful.”
