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.”

Solemn Mass • Ruins of Saint Mary’s Cathedral (Nagasaki, 1949)

Jeff Ostrowski · November 10, 2020

ERY SOON, December 7th will be here. On that day in 1949, most Rev’d Paul Aijirō Yamaguchi, Archbishop of Nagasaki, celebrated a Solemn Pontifical Mass on the ruins of Saint Mary’s Cathedral in Nagasaki. This was in honor of the 400th anniversary of the arrival of Saint Francis Xavier in Japan and concluded with veneration of the right forearm—the arm he used to conduct blessings and baptisms—of Saint Francis Xavier (inside a reliquary). Father Xavier was a very important Catholic priest whom Father Valentine Young spoke about in one of his sermons.

Nagasaki remained largely devastated by the atomic blast of 1945. Its people were still dying—slowly—from radiation poisoning. Nevertheless, they wanted to honor Saint Francis Xavier, and somebody had a camera:

A different angle shows what is left of the Cathedral:

Mass Outside Invalid?

Due to government restrictions, California has been “locked down” since March, and all our Masses are celebrated outside. A few weeks ago, someone on Facebook—who not surprisingly calls himself an ultra-traditionalist Catholic—was promoting the idea that all Masses offered outside are “invalid.” This theologian (self-proclaimed) even mockingly referred to outdoor Masses as “tent revivals.”

It would be good to remind everyone that, objectively speaking, the Holy Sacrifice of the Mass is of infinite value no matter where it’s offered: in a prison cell, outside under a tent, inside a church, and so forth. Indeed, Views from the Choir Loft for decades has been posting striking photos of the Mass celebrated outside. Saint Charles Garnier frequently offered the Holy Sacrifice of the Mass on a boat while traveling from France to Canada. By the way, Father Garnier died on 7 December 1649AD.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    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 will not be Rome to tell you what you should do, no: because you have the charism. …you have the Holy Spirit for this. If Rome were to begin to make the decisions it would be a blow to the Holy Spirit, who works in the particular Churches.”
