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.”

Reason and Mystery

Dr. Peter Kwasniewski · December 22, 2012

OMETIMES YOU HEAR people say that reasoning and mystery are opposed to each other—that the logical deductions one finds in, say, the Summa theologiae of Saint Thomas Aquinas, or even the precise dogmatic formulations of the Church’s Magisterium, are somehow at odds with the simple acceptance of mysteries of faith that human words can never explain. But this is to see things quite incorrectly. Doctrinal definition and theological exploration only intensify the ineffable truth that no formula can exhaust, by bringing its depth of mystery more fully to light. In Catholicism both “extremes” are given full play: reason, which may go as far as it dares and can, embracing the pagan wisdom of every land and time, trembling with its fragile power like a delicate blossom proud to have burst up through the cold ground of March; mystery, which exalts to infinity the caliginous light, the luminous darkness, the incomprehensible truth of God, precisely on account of, by means of, in the “face” of, questing reason. Saint Thomas on the Trinity, the Incarnation, the Eucharist, shows us human reason at its peak, where it bows down humbly in adoration. The form of the Summa and of its every article is the archetypal form of a quest for the Grail of truth, a quest made urgent not only by the inner joy of seeking but by the continual danger of perilous detours; a pilgrimage taken by the soul journeying into God, walking by its “own” power, sustained by the power and grace of God endowing it at every moment with the power that it may call its own (participated theonomy). Each extreme of theology is what it is because of the other, and to the questing soul the denial of the one is the loss of the other. Tell reason not to search, and the unsearchable mystery will become a mystery unsearched; let haughty reason tell itself that the divine is comprehensible, and at the same moment, as though by an evil spell one must never utter, it withers at its source, collapses inwardly and dies. Dispelling mystery, you take away the heart of the mind; dispelling reason, you take away the mind of the heart. And in either event, the mind and heart of love is also afflicted for its sins. This is when clerical dissipation, ecclesial polemics, and lukewarmness have their day in the sun. Let us pray and work for a full restoration of Catholic theology, Catholic spirituality, and Catholic culture—for these three stand or fall together.

    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.

    Music List • (Easter Sunday, 2026)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for Easter Sunday—a.k.a. “Ad Missam in die Paschae”—which is 5 April 2026. Please feel free to download it as a PDF file if such a thing interests you. The Fauxbourdon for Communion is particularly moving.

    PDF Download • “Sprinkling Rite”
    Liturgical reformers who gained power after Vatican II frequently caused great suffering to musicians. With the stroke of a pen, they sometimes make changes that would require thousands—or even millions—of man hours (work undertaken by composers and editors). The Sprinkling Rite during Eastertide is but one tiny example. The version given in that PDF document was the original melody for Roman Missal, Third Edition. Some still prefer that version. However, at the last moment, an “unknown hand” tinkered with a few notes in the antiphon. Those who examine the current edition can verify this with their own eyes.

    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

“Abbat Pothier’s great accomplishment is having returned to the Catholic world—along with the traditional melody—the traditional way of performing it. The foundations laid by this providential man have been accepted by all those who practice Gregorian chant.”

— Dr. Peter Wagner (Commissionis Pontificiæ Gregorianæ Membrum)
