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.”

A Triple Cord: Liturgy, Aquinas, and CST

Dr. Peter Kwasniewski · May 1, 2014

0319_Bosco_two-2-pillars Famous dream of St. John Bosco. HAT IS THE CENTER of the Catholic’s existence? The Holy Eucharist. “He who eats my flesh and drinks my blood has eternal life…” And this means that the Mass, above all other prayers, will be the activity that defines a Catholic as such. As the Mass is, so will the Catholic be. Weak, anemic, bland, and trendy liturgy will produce weak, anemic, bland, and trendy Catholics, many of whom will fall away for sheer boredom, distracted by the allurements of consumerism. Those who remain will be shaped by the ars celebrandi like clay in the potter’s hands. But if the Mass is potent, weighty, full of spiritual salt, and defiantly countercultural, so will its participants be: fed on Light, they are ready to oppose the rulers of this present darkness. They are ready to enthrone Christ as King in their souls―and as King of the universe, of every nation, people, government, and culture, including America’s. And they are ready to listen to the Popes who, over the past 700 years, have singled out St. Thomas Aquinas as the theologian par excellence of the Catholic Church, the teacher from whose heavenly wisdom all may freely drink, the servant of truth who will humbly lead them to the feet of the one and only Teacher, Jesus Christ.

The traditional liturgy, with its archaic wisdom, noble pageantry, and sublime beauty; the avid study of St. Thomas Aquinas, teacher of the universal church; Catholic social doctrine in its fullness, based on the social kingship of Christ: these three things stand or fall together. Is it really coincidental that these three all at once nearly disappeared after Vatican II and even became the object of bitter enmity and persecution? It is not for me to say what came first or what caused what. All I see is that they did stand together, and they have fallen together. Is it any surprise that, after their fall, the Church is in a state of almost total chaos, liturgically, doctrinally, socially, in spite of the superficial “signs of hope” that we hear so much about?

A true, heart-felt adherence to tradition is expressed in reverence for all the Fathers and Doctors, especially St. Thomas; reverence for the sacred liturgy they prayed and handed down to us with an observant love that extended to the tiniest details; reverence for the kind of Christian society they aspired to build and, once built, defended to the hilt. Take away any one of these things, and you take away the basis for the others.

And what of devotion to the Blessed Virgin Mary? Such devotion is the foundation on which true ecclesial reform can and must be built. Where there is true devotion to our Lady, there is also a deep love of the Church, a total commitment to the spread of the Gospel, and hence, an openness to the social dimension of the faith as well as to its theological inheritance. A Marian Catholic is, in the social realm, a supporter of the kingship of Christ; a Marian Catholic is, in the academic realm, a disciple of St. Thomas Aquinas, because Holy Mother Church has declared him her Common Doctor, and Mary is the model of obedience to authority; a Marian Catholic is, in the liturgical realm, a lover of silence, contemplation, and beauty, as was the Virgin of Nazareth. In this sense, one who would give himself entirely in prayer and praise to the Blessed Virgin Mary would necessarily be moving towards this triad of goods, and thus, be advancing the reign of the great King over all the earth.

    “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!

Random Quote

“Partly on account of these alterations, and partly because I have been unable to ascertain the authorship of many compositions—which have come to me either in manuscript or through other collections—I have thought it right to publish the volume without appending the names of writers to their works. This, however, I confess to be a defect…”

— Benjamin Hall Kennedy (1863)
