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.”

“Lauda Sion” • Rehearsal Video With Translation By Saint Robert Southwell, Jesuit Martyr

Jeff Ostrowski · June 2, 2015

HETHER YOU CELEBRATE Corpus Christi on Thursday (EF), Sunday (Novus Ordo), or Sunday (External Solemnity), you might enjoy this recording of the “Lauda Sion,” which I created this morning 1 to help choirs rehearse:


Here’s a special PDF with translation by Fr. Robert Southwell, who suffered bravely in prison for three years before gaining the crown of martyrdom:

Many of the big publishing companies skip the Corpus Christi Sequence—they literally just leave it blank. 2 When they don’t skip it, they print it like this:

    * *  COMPARISON CHART • Pew Missal Layout

Such formatting strikes me as rather utilitarian.

In the JOGUES PEW MISSAL, our team did something no other publisher has done. In addition to providing St. Robert Southwell’s translation—set to a simple Psalm Tone—we also formatted a literal translation like this:

The text of the beautiful “Lauda Sion” was written by St. Thomas Aquinas (†1274). But what about the melody? First, we must understand whence sequences come. Fr. Joseph Connelly explains:

Sequentia was the name given to the jubilus or musical prolongation of the last vowel of the word alleluia. The jubilus is divided into small sections, and to these parts separately as well as to the whole melody the name sequentia could be applied. The custom gradually came into being of adding words or a Prosa to the music of the jubilus. At first, perhaps in the eighth century, a text was added to some of the sections—the last vowel of such texts being, in some places, always the vowel a—to which the next wordless section could be sung. Later on a text was added to the whole melody and so began what is now generally called a Sequence or, less generally, a Prose. Its full name would properly be Sequentia cum prosa.

The “Lauda Sion” melody is identical to Laudes Crucis Attollamus, whose text & melody are attributed to Adam of St Victor (†1146). That Sequence was originally used for 14 September, the Feast of the Triumph of the Cross. Therefore, the melody of the “Lauda Sion” comes from the ALLELUIA JUBILUS of 14 September. Can you see the similarity?

689 Laudes crucis attollamus JUBILUS


This melody was often used. For instance, the Sunday before Corpus Christi is Trinity Sunday, which had a Sequence called Profitentes Unitatem Veneremur Trinitatem. Do you see that it uses the “Lauda Sion” melody?

687 Profitentes unitatem veneremur trinitatem


Here’s part of the “Lauda Syon” as found in a manuscript circa 1395AD:

685 “Lauda Sion”



NOTES FROM THIS ARTICLE:

    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 • “Communion” (5th Sunday in Ordin.)
    The COMMUNION ANTIPHON for this coming Sunday, 8 February 2026—which is the 5th Sunday in Ordinary Time (Year A)—is truly delightful. You can download the musical score completely free of charge. This text will be familiar to altar boys, because it’s PSALM 42. The Feder Missal makes the following claim about that psalm: “A hymn of a temple musician from Jerusalem: he is an exile in a heathen land, and he longs for the holy city and his ministry in the Temple there. The Church makes his words her own.”

    Funeral Music “Template” • For Families
    Many have requested the MUSICAL TEMPLATE for funerals we give to families at our parish. The family of the deceased is usually involved in selecting Number 12 on that sheet. This template was difficult to assemble, because the “Ordo Exsequiarum” has never been translated into English, and the assigned chants and hymns are given in different liturgical books (Lectionary, Gradual, Order of Christian Funerals, and so on). Please notify me if you spot errors or broken links. Readers will be particularly interested in some of the plainsong musical settings, which are truly haunting in their beauty.

    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

To the extent that the new sacred music is to serve the liturgical celebrations of the various churches, it can and must draw from earlier forms — especially from Gregorian chant — a higher inspiration, a uniquely sacred quality, a genuine sense of what is religious.

— Pope John Paul II (June 1980)
