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.”

Benedict XVI • Many years ago, we uploaded a stunning Blog Header image. Some have asked why Cardinal Ratzinger is featured instead of Pope Emeritus. The fact of the matter is, young Ratzinger has always been present on our header—even though our blog began after the election of Benedict XVI. The following paragraphs explain why.

It’s no secret that many who hopped on the “B16 Bandwagon” abandoned the liturgical movement when Pope Benedict XVI abdicated on 28 February 2013. It demonstrates that these authors—instead of being committed to perennial ideals—simply got caught up with a “trend.” However, if you examine the biographies of our contributors, most of us were involved in promoting authentic sacred music long before Benedict XVI was elected, and at least a decade before Summorum Pontificum was issued. We recall that the liturgy does not depend on the priorities or “taste” of a pope. Indeed, there were decades in our Church’s history when nobody knew who the true pope was! Yet, the liturgy continued. Assisting at Mass, where Christ is truly present, must be the summit of our existence: not “trends.”

Cardinal Ratzinger, therefore, is featured because of the crucial role he played before he was elected pope. This does not minimize what he did as pope; and without question, the most important thing Ratzinger accomplished as pope was to make it forever impossible for anyone to assert that those desiring authentic liturgy are “living in the past,” because documents such as Summorum Pontificum and Universae Ecclesiae were issued in the last decade, whereas documents such as Sacrosanctum Concilium and Inter Oecumenici were issued 50+ years ago. The artist (Igor Kazarin) drew Cardinal Ratzinger circa 1988, based on various photographs we provided. The artist used a “modern” technique where only one element—Ratzinger’s hat—is colored, and the rest is black & white. This is symbolic of CCWatershed, where we promote tradition, but use modern techniques to spread it. Furthermore, take a look at this photograph of Cardinal Ottaviani dressed in his cardinal’s vestments. One reason cardinals wear red is to demonstrate their willingness to shed blood for the Gospel. Ratzinger was certainly a “martyr” in terms of the abuse he suffered from the anti-Catholic press. We believe that today’s church musicians must be “martyrs” to overcome the difficulties they face. But red is also used for the Holy Ghost; how fitting and significant! We require the Holy Ghost’s guidance to be good church musicians!

    Simplified Accomp. • Schubert’s “Ave Maria.”
    Sometimes the organist must simultaneously serve as the CANTOR. (Those who work in the field of church music know exactly what I’m talking about.) One of our contributors composed this simplified keyboard accompaniment for Franz Schubert’s “Ave Maria,” a piece which is frequently requested for Catholic funerals and weddings. In terms of the discussion about whether that piece is too theatrical (‘operatic’) for use in Church, I will leave that discussion to others. All I know is, many church musicians out there will appreciate this simplified version.

    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 in 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.

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

The Princess of the Palatinate once described German Protestantism to Louis XIV with this formula: “In our country, everyone makes up his own little religion.” Every priest, or almost every priest, is at this point today. All the faithful have to say is “Amen.” They are still blessed when the pastor’s religion does not change every Sunday, at the whim of his reading, the foolery he has seen others at, or at his own pure fancy.

— Professor Louis Bouyer (1968)
