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.”

Sacred Architecture & the Dedication of the Lateran Basilica

When we come to church, there should be no question whether we are in a church or in a coffeehouse or in a multipurpose gym.

Fair-Weather Friends Of Good Liturgy & Pope Francis

The catastrophic scandals in our Church, especially those perpetrated by members of the hierarchy, are an opportunity for us to place all of our trust in God.

Richard J. Clark · March 21, 2014

Reverent and welcoming parishes are not mutually exclusive.

Yes, the house is on fire. Yes, liturgy is important. Seriously? Yes.

Benedict Brought Peace To The Church With “Summorum Pontificum”

“If the right is given to African tribes to include their pagan traditions in the liturgy, I think the same should also be given to the rite of a thousand year-old Christian Church, based on a much older Roman tradition.” — László Dobszay

Jeff Ostrowski · January 24, 2014

Ratzinger: “How much filth there is in the church!”

“Have mercy on your church,” Cardinal Ratzinger prayed in 2005. “When we fall, we drag you down to earth, and Satan laughs, for he hopes that you will not be able to rise from that fall; he hopes that being dragged down in the fall of your church, you will remain prostrate and overpowered.”

Francis on Benedict’s “Enlightened Conscience”

The Pope Emeritus “prays, reads, listens to music, dedicates himself to his correspondence, which is a lot, and receives visitors. Every day we walk together in the woods behind the monastery, reciting the rosary.” — Archbishop Ganswein (10/22/13)

Jeff Ostrowski · November 19, 2013

Rory Cooney Needs “Healing” From Pope Benedict’s Liturgical Reforms

Consider these lines from GIA’s newest hymnal (Worship IV): “Who is this who eats with sinners, calling luckless losers winners?” Did they really just use the phrase “luckless losers” in a Catholic hymn book?

Jeff Ostrowski · October 30, 2013

Definition Of Liturgical “Piccoluomini” ?

Human beings are “geared” toward annual events. Our minds, emotions, and memories simply aren’t programmed to work in 3-year cycles.

President’s Corner

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

    You won’t believe who recently gave us a “like” on the Corpus Christi Watershed FACEBOOK PAGE. Click here (PDF) to see who it was. We were not only sincerely honored, we were utterly flabbergasted. This was truly a resounding endorsement and unmistakable stamp of approval.

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”
    —Jeff Ostrowski
    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.
    —Jeff Ostrowski

Random Quote

“In older times we referred to humans as the human race, but according to this foundation we are being classed with the animals on the farm, the cow, the horse, the mule […] According to this foundation, I have no right to be born, for I am the youngest of 16 children, and God bless my mother for every one of them!”

— Archbishop Schrembs (d. 1945) vs. a foundation promoting artificial contraception
