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.”

    “Music List” • 19th in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 19th Sunday in Ordinary Time (10 August 2025). 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 feasts website.
    —Jeff Ostrowski
    This Sunday’s Communion Antiphon
    This coming Sunday—10 August 2025—is the 19th Sunday in Ordinary Time (Year C). The COMMUNION ANTIPHON is really gorgeous, and two of its features are worth mentioning. First of all, the Gospel reading assigned is from Saint Luke, whereas the the antiphon—although it matches the account—comes from Saint Matthew. (If anyone can point to a similar example, please notify me.) Furthermore, if you look at the authentic Gregorian Chant version posted on the feasts website, you’ll notice that it’s MODE III but ends on the ‘wrong’ note. A comparable instance of such a ‘transposed’ chant would be KYRIE IV.
    —Jeff Ostrowski
    Using “Ye” Vs. “You” Correctly
    Using “Ye” vs. “You” is rather tricky, because it depends upon which era one is trying to recreate—if that makes any sense. In other words, the rules haven’t always been the same for these two. Nevertheless, Father Philip George Caraman (the legendary Jesuit scholar) gives us a masterclass using Saint Luke’s Gospel. Father Caraman was close friends with Monsignor Ronald Knox, Evelyn Waugh, and Sir Alec Guinness.
    —Jeff Ostrowski

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

The claim that the bishop or the priest originally celebrated “versus populum” is a legend, which Otto Nussbaum (d. 1999) originally did a great deal to spread.

— Dr. Helmut Hoping (University of Freiburg)
