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.”

Jeff Ostrowski · March 9, 2026

ATHER VALENTINE Young used to say: “Some are incapable of saying three simple words: I don’t know.” After Vatican II, certain reformers pretended to be omniscient. More importantly, they insisted erroneously that translating everything into the vulgar tongue meant the ‘assembly’ would instantly understand. Their efforts were egregiously misguided. First of all, everyone at Mass has a different level of education. Adrian Fortescue (in a feat that even today makes certain people seethe with envy) earned three doctorates—but how many possess such knowledge? Some people have learning disabilities; another segment is illiterate; still others are hard of hearing; etc.

Facing Facts • In spite of what some claim, many prayers and readings are unclear. Monsignor Knox pointed out a particular line from Sacred Scripture in which one excellent version has “a holy person” but an equally excellent version has—for that same word—“hyena.” We can’t know for certain the ‘correct’ version, and only a very foolish & stubborn person would claim that “hyena” is basically the same thing as “a holy person.” Father Valentine was spot on: some would rather cut off their right arm then say: “I don’t know.” In a minute, I will return to this subject.

Here’s the direct URL link.

The free organ accompaniment is conveniently posted at the flourishing feasts website.

Regarding What We Know • Years ago, I knew two priests who seemed to know everything. Please remember that this was decades before artificial intelligence such as ChatGPT, Grok, Google Gemini, and so forth.1 I remember sending the following image (which is the beginning of the ROMAN CANON) to one of those priests:

White Sticks • I was clever enough to understand the Pascha nostrum immolátus est Christus reference, but I wanted to know why the Apostles were holding white sticks in their hands. The priest was kind enough to reply as follows:

Sic autem comedétis illum: renes vestros
accingétis, et calceaménta habébitis in
pédibus, tenéntes báculos in mánibus…

From the book of Exodus, it means: “And thus you shall eat it: you shall gird your reins, and you shall have shoes on your feet, holding staves in your hands…”

So I guess there were people who actually did know everything!

Maundy Thursday • For the record, here’s how the “Nos Autem” appears in the Sherborne Missal, choosing to emphasize not the Holy Eucharist—nor the Pascal Lamb—but ‘service’ to others and the institution of Holy Orders:

1 I’m personally opposed to “artificial intelligence” because I believe it harms learning, makes us less human, and—for the record—often provides information that’s false. My personal belief is that AI is going to cause a tremendous amount of harm. I suppose time will tell.

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

Random Quote

“We know that originally the offertories of the repertoire included a series of verses, just like the introit and the communion, but generally more ornate. Many of these are musical compositions of great beauty. They quickly fell into disuse, and we find them only in the most ancient manuscripts. The only remaining trace of this older arrangement in our present-day liturgy is that of the offertory of the Requiem Mass.”

— Dom Joseph Gajard (1956)
