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.

    Music List • (3rd Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday: the 3rd Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the monumental feasts website alongside the official texts in Latin.

    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

    PDF Download • Introit (3rd Sn. Ord.)
    This coming Sunday, 25 January 2026, is the 3rd Sunday in Ordinary Time (Year A). The ENTRANCE CHANT (“Dóminus secus mare”) is somewhat rare because it comes from the New Testament. The authentic version in Latin—of astounding antiquity—was jettisoned in 1955 but restored in 1970. This rehearsal video has me attempting to sing the melody while simultaneously accompanying myself on the organ. I encourage you to print off the organ accompaniment (PDF) and play through it because it has extremely ‘happy’ harmonies.

Quick Thoughts

    “Reminder” — Month of January (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. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    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.
    —Jeff Ostrowski
    PDF Download • “In Paradisum” in English
    We always sing the IN PARADISUM in Latin, as printed on this PDF score. I have an appallingly bad memory (meaning I’d be a horrible witness in court). In any event, it’s been brought to my attention that 15 years ago I created this organ accompaniment for the famous and beautiful ‘IN PARADISUM’ Gregorian chant sung in English according to ‘MR3’ (Roman Missal, Third Edition). If anyone desires such a thing, feel free to download and print. Looking back, I wish I’d brought the TENOR and BASS voices into a unison (on B-Natural) for the word “welcome” on the second line.

Random Quote

“I ask that future priests, from their time in the seminary, receive the preparation needed to understand and to celebrate Mass in Latin, and also to use Latin texts and execute Gregorian chant; nor should we forget that the faithful can be taught to recite the more common prayers in Latin, and also to sing parts of the liturgy to Gregorian chant.”

— Statement by the Supreme Pontiff (Sacramentum Caritatis, 22-feb-2007)
