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.”

Assumption Mass

Fr. David Friel · August 13, 2014

OR ALL THOSE in striking distance of the Delaware Valley, please make note of the open invitation to the Assumption Mass being offered this Friday evening in Philadelphia. The Assumption Mass tradition began fourteen years ago as an act of gratitude to God for the establishment of Mater Ecclesiae, the first diocesan-owned and staffed TLM parish in the United States (part of the Camden Diocese). This is the first year that the Mass will be celebrated in the Cathedral Basilica of Ss. Peter & Paul in Philadelphia.

The Celebrant of the Mass, who will also deliver the sermon, is Msgr. Andrew Wadsworth. Originally a priest of the Diocese of Westminster, London, he is now the superior of the Oratorian Community of St Philip Neri, an oratory in formation in the Archdiocese of Washington. Msgr. Wadsworth has also served as Executive Director of the International Commission for English in the Liturgy (ICEL) since 2009, responsible for the English translations of Latin liturgical texts for use in the Anglophone world.

Each year, the Assumption Mass features terrific orchestral and choral music. This year, the Ordinary of the Mass will be the Missa in Angustiis, or “Lord Nelson Mass,” of Franz Joseph Haydn, sung with full orchestra. Other works will include the motets Salve Regina by Antonio Salieri, Salutatio D.N.I.C. by Ludwig Senfl, Beata Viscera Gregor Aichinger, the Adagio from Tomaso Albioni’s Concerto for 2 Oboes in G Major, the Hodie Maria Virgo by Luca Marenzio, and the Tantum Ergo by Mozart. The postlude will be Concerto for 2 trumpets in D Major by Giuseppe Maria Jacchini. The traditional hymns O Sanctissima and Hail, Holy Queen, arranged by the Music Director, Dr Timothy McDonnell, will also be sung.

This Solemn High Mass of the Assumption, celebrated in the Extraordinary Form, will begin at 7 PM at the Cathedral Basilica of Ss. Peter & Paul (18th Street & Benjamin Franklin Parkway). All are welcome.

    Our tiny 501(c)3 nonprofit organization exists solely by generous readers who donate $5.00 per month. We have no endowment; we have no major donors; we run no advertisements; we have no savings. A donor wrote to us: “I so appreciate all you do and have done, and your generosity is unprecedented. I am honored to be able to make a monthly contribution.” Another monthly donor says: “Thank you for everything CC Watershed does. We are able to add so much solemnity to Holy Mass due to the resources made available here.” Can you spare a few dollars each month to help us survive?

    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

This was first breach in the walls of a fortress, centuries old, stoutly built, strong and robust, but no longer capable of responding to the spiritual needs of the age. [N.B. the “fortress” is a liturgy which nourished countless great saints.]

— Annibale Bugnini (19 March 1966)
