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.”

If Cardinal Nichols had simply sent a letter saying why he prefers “versus populum,” I believe that would have been a better choice.

    “Music List” • 23rd in Ordinary Time (Year C)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 7 September 2025, which is the 23rd Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the spectacular feasts website alongside the official texts in Latin. My singers really enjoy singing the resplendent COMMUNION ANTIPHON with its Fauxbourdon verses.
    —Jeff Ostrowski
    PDF Download • Draft Copy (Pamphlet)
    A few days ago, I posted a draft copy of this 12-page pamphlet with citations about the laity’s “full, conscious, and active participation.” Its basic point or message is that choir directors should never feel embarrassed to teach real choral music because Vatican II explicitly ordered them to do that! We’ve received tons of mail regarding that pamphlet, with many excellent suggestions for improvement. Please feel free to chime in!
    —Jeff Ostrowski
    “Entrance Chant” • 23rd (Ordinary Time)
    This coming Sunday, 7 September 2025, is the 23rd Sunday in Ordinary Time (Year C). You can download the “Entrance Chant,” conveniently located at the feasts website. I also recorded a rehearsal video for it (freely available at the same website). The Communion Chant includes gorgeous verses in FAUXBOURDON. I attempted to create a rehearsal video for it, and it’s been posted at the feasts website, called by some: “church music’s best kept secret.”

Quick Thoughts

    Karl Keating • “Canonization Questions”
    We were sent an internet statement (screenshot) that’s garnered significant attention, in which KARL KEATING (founder of Catholic Answers) speaks about whether canonizations are infallible. Mr. Keating seems unaware that canonizations are—in the final analysis—a theological opinion. They are not infallible, as explained in this 2014 article by a priest (with a doctorate in theology) who worked for multiple popes. Mr. Keating says: “I’m unaware of such claims arising from any quarter until several recent popes disliked by these Traditionalists were canonized, including John XXIII, Paul VI, and John Paul II. Usually Paul VI receives the most opprobrium.” Mr. Keating is incorrect; e.g. Saint John Vianney, several centuries ago, taught clearly that canonizations are not infallible.

    Solemn “Salve Regina” (Chant)
    How many “S” words can you think of using alliteration? How about Schwann Solemn Salve Score? You can download the SOLEMN SALVE REGINA in Gregorian Chant. The notation follows the official rhythm (EDITIO VATICANA). Canon Jules Van Nuffel, choirmaster of the Cathedral of Saint Rumbold, composed this accompaniment for it (although some feel it isn’t his best work).

    Pope Pius XII Hymnal?
    Have you ever heard of the Pope Pius XII Hymnal? It’s a real book, published in the United States in 1959. Here’s a sample page so you can verify with your own eyes it existed.

“In my opinion, there should be reached the aim that all priests could continue to use the old Missal.”
