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.”

Laws of life

Andrew R. Motyka · October 9, 2013

hings have been quite hectic for the last couple of weeks, leading to my missing my scheduled post last week. Apologies all around. This week I would briefly like to focus on a brief prayer that my choir prays prior to each rehearsal and Mass. It is the RSCM Choristers’ Prayer, and I learned it while working with Charles Cole at the 2011 CMAA Colloquium in Pittsburgh:

Bless, O Lord, us Thy servants who minister in Thy temple. Grant that what we sing with our lips, we may believe in our hearts, and what we believe in our hearts, we may show forth in our lives. Through Jesus Christ our Lord, Amen.

According to the site linked above, the prayer has been almost unchanged since its origins as a blessing for cantors from the Fourth Council of Carthage (ca. 398). What I find particularly interesting about this prayer, though, is its simple articulation of an important concept in liturgical theology: lex orandi, lex credendi.

Lex orandi, lex credendi is a mnemonic for the idea that “the law of prayer is the law of belief.” Our liturgical prayer, in form and execution, bears heavily on our faith. This is why careful ars celebrandi (i.e., the style and reverence of sacramental celebration) is to be fostered. Irreverent treatment of the matters of liturgy will, over time, damage the faithful’s understanding and attitude toward sacred matter. As one of my graduate professors, Leo Nestor, used to say of careless and vapid musical choices: “That kind of music will rot your teeth and erode your faith.”

Likewise, a reverent ars celebrandi fosters a more healthy faith. When serious things are treated seriously by the priest, servers, choir, and other ministers, it has an influence on the way those things are treated by the faithful. What I also love about this prayer is continuation into the next part of the traditional principle: lex orandi, lex credendi, lex vivendi. Our law of prayer forms our law of belief, which forms our lives. Remember that the liturgy is not educational, but it is formative, so serious celebration and good musical choices will assist in the forming of the very lives of the faithful.

Again, as Dr. Nestor used to say, “Always be careful what words you put into the mouths of the people of God.” We should take that advice seriously.

    PDF • “Cantus Mariales” (192 pages)
    Andrea Leal has posted an absolutely pristine scan of CANTUS MARIALES (192 pages) which can be downloaded as a PDF file. To access this treasure, navigate to the frabjous article Andrea posted Monday. The file is being offered completely free of charge. The beginning pages of the book have something not to be missed: viz. a letter from Pope Saint Pius X to Dom Pothier, in which the pope calls Abbat Pothier “a man versed above all others in the science of liturgy, and to whom the cause of Gregorian chant is greatly indebted.”

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    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

It would be contrary to the Constitution to decree or even to hint that sung celebrations, especially of the Mass, should be in Latin.
