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 · January 21, 2020

HEN I PLAY organ for Vespers on Sunday afternoon, sometimes I have to jump in and sing. It doesn’t happen often—because we usually have at least 30-40 singers—but on certain days it’s necessary…such as the Sunday before Thanksgiving, when the attendance was quite sparse! We normally do the “Lucis Creator Optime” to a metrical hymn setting, taken from the Brébeuf Hymnal (since everything else is sung in plainsong) but sometimes we sing the plainsong version.

I composed this organ accompaniment following the “Brébeuf method,” where every verse is written out:

Perhaps my favorite thing about the Saint Jean de Brébeuf Hymnal is how every single verse of the organ accompaniments is carefully written out. It makes life so easy, I actually feel guilty! Notice how the accompaniment provides contrasting accompaniments for the same melodic phrase; one has the bass line in descending stepwise motion, while the other has the bass line in ascending stepwise motion:

But the Brébeuf Hymnal is hardly the first book to recognize how essential it is to write out every verse. Take a look at this special Paris edition of the Antiphonale, printed in 1913:

By the way, the approbation in the front of that book is by Cardinal Martinelli, who wrote a very important letter condemning the “Mocquereau” rhythm, the “Wagner” rhythm, and the “Haberl” rhythm. We shall speak of that letter another day…

I think you’ll agree we have made tremendous progress since 1851, when this accompaniment appeared:

(That is from an 1851 book called “Hymnarium Vesperale.”)

    “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.

    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.

    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.

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.

    “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 introduction of the vernacular will certainly be a great sacrifice for those who know the beauty, the power and the expressive sacrality of Latin. We are parting with the speech of the Christian centuries; we are becoming like profane intruders in the literary preserve of sacred utterance. We will lose a great part of that stupendous and incomparable artistic and spiritual thing, the Gregorian chant. We have reason indeed for regret […] We are giving up something of priceless worth.”

— Pope Paul VI
