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.”

How do you pronounce this word in Latin?

Jeff Ostrowski · September 15, 2025

HIS YEAR, the second Sunday of November will be replaced by a special feast: Dedicatio Basilicae Lateranensis. Where did the feast come from? Why is this feast so weighty that it “overpowers” a Sunday? If you scroll down to the bottom, I attempt to provide the answer to both questions. Today, however, I would like to narrow my focus to the COMMUNION ANTIPHON (Jerúsalem Quae Aedificátur Ut Cívitas), which is familiar to us since it’s traditionally sung on the 4th Sunday of Lent.

One Latin Word • More specifically, today I focus on a single word from that COMMUNION ANTIPHON: idípsum. For many years, we have attempted to explain Trochee Trouble, with varying levels of success. Countless readers still struggle to comprehend it, but this single word—idípsum—illustrates the problem admirably. See if you can tell the difference between the FRENCH TROCHEE and the GERMAN TROCHEE:

Disunity • The long and short of it (pardon the pun) has to do with language. The French place accents on the final syllables whereas the German language has ‘heavy’ or ‘stressed’ tonic accents. Because Dom Mocquereau was French, he favored the final accent of each word—perhaps hoping those unfamiliar with Latin wouldn’t notice. The German school took a different approach. As a result, the EDITIO VATICANA is sung differently depending on which Trochee ‘school’ is adopted.

Analysis • I feel that singing idípsum according to the French school would be quite painful for anyone who truly knows Latin. Do you agree or disagree?

Father Lasance Speaks
9 November • Dedication of the Lateran Basilica

As the anniversary of the dedication of a cathedral is kept as a solemn festival in all the churches of a diocese, so the dedication of the Church of Saint John Lateran, the cathedral of the Supreme Pontiff, is everywhere celebrated. The first mention of the Lateran in ecclesiastical history is that of Optatus of Milevis who relates that a Council against the Donatists was held within its walls. About this time Constantine gave to the Church of Rome the ancient Palace of the Laterani, part of the dowry of his wife, Fausta.

From that time onwards the Lateran became the ordinary residence of the Popes, and may be regarded as a memorial of that long series of holy Pontiffs who inhabited it during the course of nearly ten centuries. Those walls, now nearly two thousand years old, have seen many important events in history and have figured in poetry and in art, whilst they sheltered a dynasty of Pontiffs who ruled longer than any dynasty of kings. Here, at the suggestion of Pope Sylvester, Constantine the Great transformed or constructed the first basilica dedicated to the Saviour at Rome. In the Twelfth Century, on account of the baptistery, it was dedicated to Saint John the Baptist and began to be called Saint John Lateran. In the early Middle Ages the Pope officiated, not at one church only, but in all the basilicas and titles within and without the city. On great solemnities and for ordinations and coronations, he officiated at Saint Peter’s. When the observance of the stations declined, the Lateran was ranked as the Papal residence, and the basilica was looked upon as a cathedral with regard to the other titular churches of the city.

As papal cathedral and mother of all the churches, the Basilica of the Saviour has been clothed with the dignity of a symbol of the Pontifical authority in the eyes of the Catholic world. The Liturgy has also concentrated in her ritual this belief held by the household of the faith, and Pius X raised the feast which we celebrate today to the same rank of a double of the second class for the entire Latin Church, as is held by the great feasts of the religious year.

In this basilica and the Latern Palace five ecumenical councils were held, besides twenty synods. The basilica, after its destruction, was rebuilt by Benedict XIII and consecrated on 9 November 1726. Since that time the feast has been kept in the Universal Church. The dedication of a church is an important liturgical event. It is not the same thing to pray in private, or to pray in the sacred sanctuary and to take part in the rites of Catholic Liturgy. By reason of its consecration the Church is the throne of God’s mercy, the place chosen by Him, and where He chiefly condescends to work our salvation. Here we know He listens to our prayers; here Jesus is pleased to receive from the assembly of believers that solemn, public, and united adoration which is due to Him.

Die 9 novembris • In Dedicatione Basilicae Lateranensis
Dedicatio Basilicae Lateranensis, 9 novembris

The Dedication of the Archbasilica of Our Holy Savior
In Dedicatione Basilicæ Ss. Salvatoris
November 9 • Dedication of the Church of our Savior
Dedication of Our Savior’s Church

Older liturgical books—such as Catholic Almanac & Laity’s Directory (Baltimore)—call it: “Dedication of St. Saviour’s.” The Basilica of Saint John Lateran is the cathedral of the diocese of Rome and the official ecclesiastical seat of the Holy Father. The Basilica is also called the “Church of Holy Savior” or the “Church of Saint John Baptist.”

    Music List • (2nd Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 2nd Sunday of Lent (1 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has magnificent propers. Its somber INTROIT is particularly striking—using a haunting tonality—but the COMMUNION with its fauxbourdon verses is also quite remarkable. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

Quick Thoughts

    Extreme Unction
    Those who search Google for “CCCC MS 079” will discover high resolution images of a medieval Pontificale (“Cambridge, Corpus Christi College, MS 079”). One of the pages contains this absolutely gorgeous depiction of the Sacrament of Extreme Unction.

    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

“A striking detail: at Solesmes, we remember hearing Justine Ward criticize accompaniment sometimes or seeing her cover her ears, especially when the organ accompanied a soloist, which is something she could not accept.”
