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.”

Maybe today we need missionaries of a different kind, ready to announce the beauty of our faith and tradition with an understanding of the new needs of a changing world.

Are Priests Permitted To Add More Scripture To The Ordinary Form? Yes!

Vatican II wanted more Scripture in the Mass, but somehow the reformers missed that memo.

Facebook, Scammers, and the Economy of Words

No, dear girls, I do not want to know more about you, but maybe it would be good for you to know something more about me.

Staunchly Pro-Life: Former Supermodel, Kathy Ireland

“At the moment of conception, a new life comes into being. The DNA—the genetic blueprint—is there.”

The Improbable Triumph Of The Latin Mass

“Complete equality of status for the old rite of Mass alongside the new rite … is just not going to happen.” — Fr. Brian W. Harrison (26 March 1995)

Homily: 17th Sunday in Ordinary Time (Year A)

Not too long ago I was talking with a priest who said that he did not believe that there was anyone in hell. I told him that was a very nice thought, and I too would love to believe it, but I don’t think we can count on it.

Fr. David Friel · July 27, 2014

Is Recorded Music Okay for Children?

There is a prevalent notion that young people somehow need to be accommodated in the work of divine worship. As a former child, I find this to be an errant hankering.

Five signs you might be a Hymn Geek

Hymns are influential, popular and full of history and trivial details, making a fertile ground for susceptible personalities to develop their geekish tendencies.

PDF Download: Mocquereau’s 1903 “Liber Usualis”

No longer the only one … but that’s OK.

Richard J. Clark · July 25, 2014

“The Celebration of the Liturgy is the most important act of evangelization.”

“Easy feelings and superficial affections do not, in the long run nourish the life of the believer; we need solid food of the word of God and the Eucharist, which have been from the beginning the only solid and substantial nourishment of the Christian.” — Goffredo Boselli

Dr. Peter Kwasniewski · July 24, 2014

“What Shall I Render to the Lord…”

It is impossible for us, by ourselves, to make a just return to the Lord for all He has given to us. But “with the Lord, nothing is impossible.”

Like Eve in the Garden

“The fruit in my hands was not forbidden but simply forgotten.” — Fr. Brent Maher

    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.

    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st Sunday of Lent (Year A). 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 available at the outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.

We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe!

    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

“The training in singing, to sing in a chorus, is not only an exercise of external listening and of the voice; it is also training for interior listening, listening with the heart, an exercise in training for life and for peace.”

— Pope Benedict XVI
