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.”

President’s Corner

    “Pope Leo XIV Has Announced…”
    My pastor asked me to write brief 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 most recent article speaks about the recent announcement by Pope Leo XIV, which does have an impact on church musicians. Scheduled for publication on 2025 08 10th, it’s called: “Pope Leo XIV Has Announced…”
    —Jeff Ostrowski
    “Chants” • 18th Sunday in Ordinary Time
    All the chants for 3 August 2025—which is the 18th Sunday in Ordinary Time (Year C)—have been added to the feasts website, as usual under a convenient “drop down” menu. The COMMUNION ANTIPHON (from the book of Wisdom) is stunning. That feast website has been called “the best kept secret of Church music.”
    —Jeff Ostrowski
    “Corn” From Heaven?
    The Westminster Version of the Sacred Scriptures was produced by Roman Catholics in England and bears a 15 March 1958 IMPRIMATUR from the Archbishop of Westminster. Its IMPRIMI POTEST was given by the director of the Pontifical Biblical Institute in Rome. Sometimes words chosen by translators sound funny to American ears. For instance, one of our Responsorial Psalms has as its refrain: “The Lord gave them bread from heaven.” But the British version has “The Lord gave them corn from heaven.” Feel free to examine this with your own eyes. (It comes from Psalm 77.)
    —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).

The election of Pope Leo XIV has been exciting, and we’re filled with hope for our apostolate’s future!

But we’re under pressure to transfer our website to a “subscription model.”

We don’t want to do that. We believe our website should remain free to all.
