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.”

Dr. Peter Kwasniewski · July 31, 2014

Away with the World—Let Heaven Enter

Music, for a Christian, should serve the same purpose as everything else in life: weaning us from excessive attachment to this world and lifting our souls heavenward.

Andrew R. Motyka · July 30, 2014

A Different Offering

What about NOT having congregational song during the Offertory?

Aurelio Porfiri · July 30, 2014

Felix Culpa

Life is not a piece of cake. And the Mass is not a Sunday recreational moment. We need to feel the burning of being close to God.

Jeff Ostrowski · July 30, 2014

Difference Between “Modern” and “Dark Ages”

Does modern architecture compare favorably to the architecture of the dark ages?

Aurelio Porfiri · July 29, 2014

Missionaries

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.

Aurelio Porfiri · July 28, 2014

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.”

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.

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.

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.

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

President’s Corner

    “Reminder” — Month of April (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). 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! Just scroll to the bottom of any blog article and enter your email address.

    Simplified Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!
    —Jeff Ostrowski

Random Quote

“The Night Office—Nocturns or Matins—except for Holy Week, Easter Octave, and Christmas, has never appeared in the Vatican edition. The larger part of the mediaeval repertory for the Office thus remains still unpublished in the Vatican edition, and is likely to remain so, for the obvious reason that almost no cathedral chapters or monastic choirs sing the Night Office regularly today.”

— John Merle Boe (1968)
