“Polyphonic Credo” during Communion?

It sounds strange to Americans, but a very common European tradition is to sing a polyphonic “Agnus Dei” during the distribution of Holy Communion, famously defended by Cardinal Ratzinger in 1995. Monsignor Francis P. Schmitt wrote about visiting Saint Joseph Oratory in Montreal, and says: “A polyphonic Creed was sung during the distribution of Communion.” […]

The Best We’ve Done?

Perhaps the most significant item we’ve yet had the honor of producing is an English translation of an extremely rare document from 1970. A member of the Consilium—Father Adalbert Franquesa Garrós—explains why the reformers felt it necessary to destroy most of the ancient Mass propers. In particular, this reformer priest claims that unless verses of […]

“Homily — 32nd Sunday in Ordinary Time, Year A” • Father Valentine Young, OFM

PDF Download • Vespers for the Dead

Mr. Albert Bloomfield kindly sent me “Vespers for the Dead”—which does not fulfill a priest’s obligation to pray the Divine Office, yet is often prayed when a loved one dies. Here is formatting A, and here it is again with formatting B.

“Homily for the Feast of All Saints” (November 1st) • Father Valentine Young, OFM

My mother told me that my father used to stop at the rectory every Saturday afternoon to go to confession to the priest. He died when I was eight, leaving my mother with six children…

ICEL added “Died” to the Nicene Creed • (I am not kidding!)

I bet you never noticed this, but here’s the proof! • Believe it or not, the Nicene Creed never says Our Lord “died,” and this article provides full documentation; also included are beautiful manuscript images from the greatest Dutch illuminated manuscript in the world: Catherine of Cleves Hours (15th century MS.)+

20 October 2020 • “What we can’t share”

Almighty God has given to us the example of the Jesuit Martyrs of North America, whose feast day we celebrated yesterday. Of course, along with those eight martyrs we honor their associates, e.g Father François Bressani. I can’t share with you the torments Father Bressani underwent at the hands of Iroquois: it is too brutal. […]

19 October 2020 • Feast of Father Brébeuf

Dom Pothier • “To The Eyes And To The Ears”

For years, I couldn’t understand this business about “the eyes and the ears.” What did Pothier mean? Then it hit me. • Topics include Dom Joseph Pothier, the mora vocis, Abbot Pothier’s brother (Dom Alphonse Pothier), Dom Lucien David, Dom Paul Jausions, and a truly magnificent story about Pope Pius X and Abbot Pothier, which is essential reading+

President’s Corner

    Luis Martínez Must Go!
    Sevilla Cathedral (entry dated 13 December 1564): The chapter orders Luis Martínez, a cathedral chaplain, to stay away from the choirbook-stand when the rest of the singers gather around it to sing polyphony—the reason being that “he throws the others out of tune.” [Excerpt from “The Life of Father Francisco Guerrero.”]

    Urgent! • We Desperately Need Funds!
    A few days ago, the president of Corpus Christi Watershed posted this urgent appeal for funds. Please help us make sure we’re never forced to place our content behind a paywall. We feel it’s crucial that 100% of our content remains free to everyone. We’re a tiny 501(c)3 public charity, entirely dependent upon the generosity of small donors. We have no endowment and no major donors. We run no advertisements and have no savings. We beg you to consider donating $4.00 per month. Thank you!

    “Booklet of Eucharistic Hymns” (16 pages)
    I was asked to create a booklet for my parish to use during our CORPUS CHRISTI PROCESSION on 22 June 2025. Would you be willing to look over the DRAFT BOOKLET (16 pages) I came up with? I tried to include a variety of hymns: some have a refrain; some are in major, others in minor; some are metered, others are plainsong; some are in Spanish, some are in Latin, but most are in English. Normally, we’d use the Brébeuf Hymnal—but we can’t risk having our congregation carry those heavy books all over the city to various churches.

Quick Thoughts

    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.
    —Corpus Christi Watershed
    “Hybrid” Chant Notation?
    Over the years, many have tried to ‘simplify’ plainsong notation. The O’Fallon Propers attempted to simplify the notation—but ended up making matters worse. Dr. Karl Weinmann tried to do the same in the time of Pope Saint Pius X by replacing each porrectus. You can examine a specimen from his edition and see whether you agree he complicated matters. In particular, look at what he did with éxsules fílii Hévae.

    Antiphons Don’t Match?
    A reader wants to know why the Entrance and Communion antiphons in certain publications deviate from what’s prescribed by the GRADUALE ROMANUM published after Vatican II. Click here to read our answer. The short answer is: the Adalbert Propers were never intended to be sung. They were intended for private Masses only (or Masses without music). The “Graduale Parvum,” published by the John Henry Newman Institute of Liturgical Music in 2023, mostly uses the Adalbert Propers—but sometimes uses the GRADUALE text: e.g. Solemnity of Saints Peter and Paul (29 June).

Random Quote

“To speak the language of God’s beauty, we must first begin to listen. And to listen, we must have silence in our lives. I pray that God will open our eyes and ears to beauty, and help us use it in the service of the Truth.”

— Bishop James D. Conley (10/4/2013)
