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.

    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

“It is most important that when the faithful assist at the sacred ceremonies … they should sing alternately with the clergy or the choir, as it is prescribed.”

— ‘Pope Pius XI, Divini Cultus (20 Dec 1928) §9’
