Corpus Christi Watershed

“A much greater source of anxiety to Us is the style of action of those who maintain that liturgical worship should shed its sacred character, who foolishly say we should substitute for sacred items & furnishings ordinary common things in daily use.” —Pope Saint Paul VI (14 Oct 1968)

President’s Corner

    “What Martin Luther Said…”
    My pastor asked me to write little columns for the bulletin each week. The article for 20 July 2025 has been posted, and it’s called: “What Luther Said…” Martin Luther (an ex-priest and apostate) was an infamous heretic whose ignorance of JESUS CHRIST was only exceeded by his filthy and disgusting vulgarity.
    —Jeff Ostrowski
    “Music List” • 15th in Ordinary Time (Year C)
    Some have expressed interest in perusing the ORDER OF MUSIC I prepared for the 15th Sunday in Ordinary Time (13 July 2025). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and propers for this Sunday are also provided at the the feasts website.
    —Jeff Ostrowski
    15th Sunday in Ordinary Time (Year C)
    This coming Sunday—13 July 2025—is the 15th Sunday in Ordinary Time (Year C). All the chants have been conveniently assembled and posted at the feasts website. The OFFERTORY, Ad Te Levávi, is particularly beautiful.
    —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.
    —Corpus Christi Watershed
    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).
