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 The USCCB website currently has information that—as of a few days ago—has been superseded:

*  PDF Download • PREVIOUS RULING (superseded in October 2024)

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 Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

Random Quote

“I vividly remember going to church with him in Bournemouth. He was a devout Roman Catholic and it was soon after the Church had changed the liturgy (from Latin to English). My grandfather obviously didn’t agree with this and made all the responses very loudly in Latin while the rest of the congregation answered in English. I found the whole experience quite excruciating, but my grandfather was oblivious. He simply had to do what he believed to be right.”
