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!

    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.

    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.”

    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.

Random Quote

“The replies to this committee (of which Mgr Bugnini was the secretary) reveal a desire to reform the liturgy. In what sense? Out of 2,109 responses from bishops, just three expressed the desire to restore Communion under both kinds. There was a sizable demand for limited use of the vernacular, but only one French bishop wanted the entire Mass in French.”

— Fr. Dominic Allain (2019)
