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.”

To you and your colleagues who helped produce the Brébeuf hymnal, I wanted to drop a line to say “bravo.” I just got a copy and immediately ordered the choral supplement (I ought to have just gotten it in the first place). What an achievement this book is! This is the sort of hymnal one […]

President’s Corner

    Simplified Accompaniment (Advent Hymn)
    Many organists are forced to simultaneously serve as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult. I invite you to download this simplified organ accompaniment (PDF) which in the Father Brébeuf Hymnal is hymn #661: “Come, Thou Long-Expected Jesus” (for ADVENT). I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was downloaded more than 2,900 times in a matter of hours—so there appears to be interest.
    —Jeff Ostrowski
    PDF • “Music List” (Immaculate Concep.)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 8 December 2025, the feast of OUR LADY’S IMMACULATE CONCEPTION. If such a thing interests you, feel free to download it as a PDF file. The fauxbourdon setting of the COMMUNION is exquisite. In Latin, the title of this feast is: In Conceptione Immaculata Beatae Mariae Virginis. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

Quick Thoughts

    Pope Leo XIV on Sacred Music
    On 5 December 2025, Pope Leo XIV made this declaration with regard to liturgical music.
    —Corpus Christi Watershed
    “Translations Approved for Liturgical Use”
    According to the newsletter for USSCB’s Committee on Divine Worship dated September 1996, there are three (3) translations of the Bible which can be used in the sacred liturgy in the United States. You can read this information with your own eyes. It seems the USCCB and also Rome fully approved the so-called NRSV (“New Revised Standard Version”) on 13 November 1991 and 6 April 1992 but this permission was then withdrawn in 1994.
    —Corpus Christi Watershed
    Gospel Options for 2 November (“All Souls”)
    We’ve been told some bishops are suppressing the TLM because of “unity.” But is unity truly found in the MISSALE RECENS? For instance, on All Souls (2 November), any of these Gospel readings may be chosen, for any reason (or for no reason at all). The same is true of the Propria Missæ and other readings—there are countless options in the ORDINARY FORM. In other words, no matter which OF parish you attend on 2 November, you’ll almost certainly hear different propers and readings, to say nothing of different ‘styles’ of music. Where is the “unity” in all this? Indeed, the Second Vatican Council solemnly declared: “Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community.”
    —Corpus Christi Watershed

Random Quote

“Ordained a diocesan priest on 7 October 1827, Guéranger was quickly named a canon (a member of the cathedral chapter of Tours). Around 1830, he demonstrated his interest in the liturgy when he began to use the Roman Missal and texts for the Divine Office, unlike many of his colleagues, who still made use of the diocesan editions commonly in use in pre-Revolutionary France.”
