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.”

Singing Scripture throughout Mass: Why We Must and How We Might

For a long while I’ve been ruminating on the nature of the Liturgy, Scripture as found in the Mass Propers, the Golden Calf narrative (thanks to Ratzinger’s Spirit of the Liturgy), Good Friday tradition, and episcopal authority. Here are some semi-organized thoughts on the matter.

The Cross of Christ and Liturgical Language

To effectively defend the use of the liturgical languages of the Latin Rite in the rite’s mostly vernacular Ordinary-Form expressions, we must look to the Cross.

    ‘German’ Introductions for Hymns
    German organ books have an enchanting habit of including introductions for each and every hymn. For example, consider this snazzy example found in a German hymnal published in 1902. In the Saint Jean de Brébeuf Hymnal, that melody is called “Laudes Mariae” and was married to Omni Die Dic Mariae, with a popular English translation (“Daily, daily, sing to Mary”) by Father Henry Bittleston, an Oratorian priest.

    Buckfast Abbey Weighs In
    Dom John Stéphan was a Benedictine monk of Buckfast Abbey in South Devon, England. On 4 February 1933, he published this interesting letter in THE TABLET. Have you seen the exterior of Buckfast Abbey? It’s beyond gorgeous. I doubt there’s a more arresting Abbey in the entire world. Dom Stéphan’s letter is concerning this momentous collection, which our organization obtained, scanned, and uploaded.

    Responsorial Psalm Fauxbourdon?
    When it comes to singing Responsorial Psalms in Fauxbourdon, what does this sound like in practice? Can such a thing be done successfully with volunteer choirs in real Catholic parishes? Listen to this audio excerpt from Good Friday and see what you think. Our parish volunteer choir did so well this year—and the ceremonies were ‘standing room only’. For the record, that musical score can be downloaded (completely free of charge) from the flourishing feasts website.

Quick Thoughts

    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!

    PDF Download • “Ubi Caritas” (SATB)
    I remember singing “Ubi Cáritas” by Maurice Duruflé at the conservatory. I was deeply moved by it. However, some feel Duruflé’s version isn’t suitable for small choirs since it’s written for 6 voices and the bass tessitura is quite low. That’s why I was absolutely thrilled to discover this “Ubi cáritas” (SATB) for smaller choirs by Énemond Moreau, who studied with OSCAR DEPUYDT (d. 1925), an orphan who became a towering figure of Catholic music. Depuydt’s students include: Flor Peeters (d. 1986); Monsignor Jules Van Nuffel (d. 1953); Arthur Meulemans (d. 1966); Monsignor Jules Vyverman (d. 1989); and Gustaaf Nees (d. 1965). Rehearsal videos for each individual voice await you at #19705. When I came across the astonishing English translation for “Ubi Cáritas” by Monsignor Ronald Knox—matching the Latin’s meter—I decided to add those lyrics as an option (for churches which have banned Latin). My wife and I made this recording to give you some idea how it sounds.

Random Quote

Let us ponder the incontrovertible fact that Eucharistic Adoration in the Ordinary Form (“Novus Ordo”) is always and everywhere celebrated “ad orientem.” Why, then, is there such opposition to Mass being celebrated in that way, which is actually stipulated by the 1970 Missal rubrics?
