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

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!

    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 Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.
    —Jeff Ostrowski
    “Holy Name Hymn” (2-Voice Arrangement)
    When we post a direct URL link, we frequently get thousands of downloads. But when scrolling is required, very few take the time. I mention this because those who click on this URL link and scroll to the bottom can download—completely free of charge—a clever 2-voice arrangement for a famous hymn to the Most Holy Name of Jesus. In a pinch, it can be nicely sung by one male and one female! It will be of interest to those who seek arrangements for two voices.

Quick Thoughts

    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.”

    “Reminder” — Month of January (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. Signing up couldn’t be easier: simply scroll to the bottom of any blog article and enter your email address.

    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

If it is the explicit will of the Council that the faithful are to be able to sing the “Gloria” or the “Credo” together in Latin [which it is] then indirectly there is being expressed here the obligation of regularly celebrating Mass with Latin Gregorian chant. And not merely occasionally, but with such frequency and constancy as to make the singing of these Latin texts a genuine possession of the faithful.

— Heinrich Flatten, Apostolic Protonotary & Canon Law Professor (Bonn)
