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.”

Jaw-Dropping Liturgical Manuscripts (7,055 Pages)

Jeff Ostrowski · April 6, 2015

998 Holy Sacred MSS HY DO WE LOVE our liturgical history? Does this love of ours truly make us “partakers of idolatry,” as the founder of the Mundelein Liturgical Institute recently asserted?

I don’t believe so. Our desires are natural and pleasing to God. We wish to pray using the exact same words—on the exact same days—as so many saints did. 1

Many now recognize that the innovations of Bugnini’s Consilium have impoverished the Roman Rite and were not faithful to the decrees of Sacrosanctum Concilium. This is due in large part to the internet, which has made available ancient manuscripts. Catholics can now see with their own eyes the antiquity of our liturgy.

Download 7,055 pages of ancient manuscripts below. They were made available 2 by Heinrich Heine University, and you can obtain high resolution versions by searching. The EF liturgy matches these manuscripts 98% of the time; whereas the OF liturgy sometimes 3 does not match.

Whenever possible, we have an obligation 4 to provide excerpts of ancient manuscripts for our choirs and congregations. Remember, the books below are just the tip of the iceberg!


MS-D-1 • Sacramentary … circa 867AD

506 pages.   Click here for a screenshot showing part of a page. That green circular thing is the famous “Vere Dignum Et Justum Est” monogram.


MS-D-3 • Missale … circa 955AD

621 pages.   Click here for a screenshot. Notice the drawing of Saint Augustine, as well as the famous monogram featured in the Jogues Lectionary.


MS-D-5 • Missale … circa 1507AD

267 pages.   Click here for a screenshot.


MS-D-6 • Cistercian Graduale … circa 1173AD

377 pages.   Click here for a screenshot.


MS-D-10A • Graduale … circa 1285AD

436 pages.   Click here for a screenshot.


MS-D-10B • Book of Hours … circa 1466AD

285 pages.   Click here for a screenshot.


MS-D-11 • Graduale … circa 1372AD

189 pages.   Click here for a screenshot.


MS-D-30 • Graduale (Winter Section) … circa 1502AD

427 pages.   Click here for a screenshot.


MS-D-32 • Cistercian Graduale (Winter Section) … circa 1552AD

431 pages.   Click here for a screenshot.


MS-D-35 • Graduale (Winter Section) … circa 1545AD

417 pages.   Click here for a screenshot.


UPDATE •   From a reader:

Bayerische Staatsbibliothek has made much available. Go to bsb-muenchen.de and search for e.g. Graduale, limit the search to “online resources” time to before 1600 (or whatever pleases you), and go wild. They have a wonderful policy in that whoever first asks for a digitalization of a particular manuscript pays for it and afterwards they put it online for free. Sample screenshot.

As I mentioned, this is just the tip of the iceberg. The Saint Gall library also has thousands of online images.



NOTES FROM THIS ARTICLE:

1   Moreover, our hearts and minds are lifted to God by the glorious artwork & melodies of our Catholic heritage.

2   The language and website—based in Düsseldorf—can be intimidating for Americans, so a former student kindly created the Google links you see on this page. Be sure to obey usage regulations posted on the Heinrich Heine website.

3   For instance, the Ordinary Form uses the Gradual antiphons for sung Masses, but uses the Missal antiphons for spoken Masses. The Gradual antiphons are ancient, whereas many of the “spoken” propers were created in 1969.

4   The Jogues Lectionary provides stunning manuscripts for the congregation to enjoy—as does the Campion Hymnal—both in full color. Congregations love seeing these!

President’s Corner

    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.”
    —Jeff Ostrowski
    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.

    “Reminder” — Month of Febr. (2026)
    On a daily basis, I speak to people who don’t realize we publish a free newsletter (although they’ve followed our blog for years). We have no endowment, no major donors, no savings, and refuse to run annoying ads. As a result, our mailing list is crucial to our survival. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    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.”
    —Jeff Ostrowski
    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

There is a lack of that kind of organization which favors mature judgment. Move on, move on, get it out. Schemata are multiplied without ever arriving at a considered form. The system of discussion is bad … Often the schemata arrive just before the discussions. Sometimes, and in important matters, such as the new anaphoras, the schema was distributed the evening before the discussion was to take place … Father Bugnini has only one interest: press ahead and finish.

— Cardinal Antonelli (Peritus during the Second Vatican Council)
