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.”

29 March 2021 • Condemned?

On Palm Sunday, the Passion was read. Immediately after mention is made of the betrayal by Judas, the Holy Eucharist is introduced. Is this not a condemnation of “Christians” who deny the Church teaching on the SANCTISSIMUM? Here is Matthew 26: And Judas that betrayed him, answering, said: “Is it I, Rabbi?” He saith to […]

Church Music’s Best Kept Secret!

Here’s a 20-second audio clip (live) from yesterday. It’s the INTROIT from Passion Sunday, when the Gospel says Jesus “hid himself” because the crowds wanted to kill Him…after He said He was greater than Abraham. Our parish uses The Saint Jean de Brébeuf Hymnal for all sung Masses, and we cherish the choral supplement because […]

18 March 2021 • “Close To Death”

When it seemed Father Jean de Brébeuf and his companions were about to meet death on 28 October 1637, he wrote a letter to his superiors. Here’s an excerpt: “It is a singular favor that His Goodness gives us, to allow us to endure something for love of Him. Now it is that we consider […]

Singers • High or Low?

I consider myself a “flexible” choirmaster. When I sing with men who have low voices, I join with them at a low pitch. Here’s an excerpt from yesterday, which was LAETARE SUNDAY (the 4th Sunday of Lent). Later that same day, I sang at another Mass with a singer who has a very high voice. […]

11 March 2021 • From Last Sunday…

Like everyone else, we are struggling under the Covid-19 restrictions. The number of singers we’re allowed have has been reduced in a severe way. But we charge forward, trusting in God. Here is a 50-second live excerpt from Mass last Sunday here in Los Angeles. Not many voices, but still beautiful (in my humble opinion).

    New Bulletin Article • “21 September 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 21 September 2025) discusses some theological items—supported by certain verses in ancient Catholic hymns—and ends by explaining why certain folks become delirious with jealousy when they observe feats by Monsignor Ronald Knox.

    Cheap! Cheap! Cheap!
    It’s always amusing to see old diocesan newspapers—in huge capital letters—advertising the Cheapest Catholic Paper in the United States. The correspondent who sent this to me added: “I can think of certain composers, published by large companies in our own day, who could truthfully brag about the most tawdry compositions in the world!” I wonder what she could have meant by such a cryptic comment…

    PDF Download • Dom Murray Harmonies
    Along with so many others, I have deep respect for Dom Gregory Gregory Murray, who produced this clever harmonization (PDF) of “O SANCTISSIMA.” It’s always amazed me that Dom Gregory—a truly inspired composer—was so confused when it came to GREGORIAN CHANT. Throughout his life, he published contradictory statements, veering back-and-forth like a weather vane. Toward the end of his life, he declared: “I see clearly that the need for reform in liturgical music arose, not in the 18th and 19th centuries, but a thousand years earlier—in the 8th and 9th centuries, or even before that. The abuses began, not with Mozart and Haydn, but with those over-enthusiastic medieval musicians who developed the elaborate and flamboyant Gregorian Chant.”

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. Father John Vianney, several centuries ago, taught clearly that canonizations are not infallible. Archbishop Fulton J. Sheen would be another example, although clearly much more recent than Saint John Vianney.

    Vatican II Changed Wedding Propers?
    It’s often claimed that the wedding propers were changed after Vatican II. As a matter of fact, that is a false claim. The EDITIO VATICANA propers (Introit: Deus Israel) remained the same after Vatican II. However, a new set of propers (Introit: Ecce Deus) was provided for optional use. The same holds true for the feast of Pope Saint Gregory the Great on 3 September: the 1943 propers (Introit: Si díligis me) were provided for optional use, but the traditional PROPRIA MISSAE (Introit: Sacerdótes Dei) were retained; they weren’t gotten rid of. The Ordo Cantus Missae (1970) makes this crystal clear, as does the Missal itself. There was an effort made in the post-conciliar years to eliminate so-called “Neo-Gregorian” chants, but (contrary to popular belief) most were retained: cf. the feast of Christ the King, the feast of the Immaculate Conception, and so forth.

    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).

Random Quote

The local church should be conscious that church worship is not really the same as what we sing in a bar, or what we sing in a convention for youth.
