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

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!

    PDF Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    “Reminder” — Month of May (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.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.
