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

    Cardinal Ranjith on “Active Participation”
    From 2005–2009, Malcolm Cardinal Ranjith served as Secretary of the Congregation for Divine Worship and the Discipline of the Sacraments. He was considered ‘papabile’ during the last conclave. On 8 December 2008, he wrote this powerful statement concerning Gregorian Chant, participatio actuosa, celebration “ad orientem,” and other subjects. When it comes to the question of what “sacred” means, Monsignor Robert A. Skeris provides a marvelous answer.

    “Music List” • 22nd in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 31 August 2025, which is the 22nd Sunday in Ordinary Time (Year C). 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 spectacular feasts website alongside the official texts in Latin.
    —Jeff Ostrowski
    “The Worm That Dieth Not”
    My pastor asked me to write a column for our parish bulletin with reflections on the sacred liturgy and church music. In my most recent article, I discuss “The Worm That Dieth Not.” At this website, you can access it conveniently; simply scroll down to the one dated 31 August 2025.

Quick Thoughts

    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).
    —Corpus Christi Watershed
    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.

Random Quote

“As late as 1834, British society had many restrictions on any person not adhering to the Anglican church. For example, Roman Catholics could not attend a university, serve on a city council, be a member of Parliament, serve in the armed forces, or even serve on a jury.”
