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.

Unmasking the Media’s Mythical Divide Between Popes

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)

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.

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

    PDF • “Cantus Mariales” (192 pages)
    Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”
    —Jeff Ostrowski
    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

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
