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

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

    (Part 2) • Did they simplify this hymn?
    Choirs love to sing the resplendent tune called “INNSBRUCK.” Looking through a (Roman Catholic) German hymnal printed in 1929, I discovered what appears to be a simplified version of that hymn. Their harmonization is much less complex than the version found in the Father Brébeuf Hymnal (which is suitable for singing by SATB choir). Please download their 1929 harmonization (PDF) and let me know your thoughts. As always, the Germans added an organ INTRODUCTION. For the record, I posted a different harmonization a few months ago which was downloaded more than 2,000 times.

    PDF • “Lectionary Comparison Chart”
    Various shell corporations (in an effort to make money selling Sacred Scripture) have tinkered with the LECTIONARY texts in a way that’s shameful. It’s no wonder Catholics in the pews know so few Bible passages by heart. Without authorization, these shell corporations pervert the official texts. Consider the Responsorial Psalm for the 1st Sunday of Advent (Year A). If you download this PDF comparison chart you’ll notice each country randomly omits certain sections. Such tinkering has gone on for 60+ years—and it’s reprehensible.

    Monsignor Klaus Gamber Speaks!
    An interesting quotation from the eminent liturgist, Monsignor Klaus Gamber (d. 1989): “According to canon law, a person’s affiliation with a particular liturgical rite is determined by that person’s rite of baptism. Given that the liturgical reforms of Pope Paul VI created a de facto new rite, one could assert that those among the faithful who were baptized according to the traditional Roman rite have the right to continue following that rite; just as priests who were ordained according to the traditional Ordo have the right to exercise the very rite that they were ordained to celebrate.”

Quick Thoughts

    New Bulletin Article • “12 October 2025”
    My pastor requested that I write short articles each week for our parish bulletin. Those responsible for preparing similar write-ups may find a bit of inspiration in these brief columns. The latest article (dated 12 October 2025) talks about an ‘irony’ or ‘paradox’ regarding the 1960s switch to a wider use (amplior locus) of vernacular in the liturgy.
    —Jeff Ostrowski
    “American Catholic Hymnal” (1991)
    The American Catholic Hymnal, with IMPRIMATUR granted (25 April 1991) by the Archdiocese of Chicago, is like a compendium of every horrible idea from the 1980s. Imagine being forced to stand all through Communion (even afterwards) when those self-same ‘enlightened’ liturgists moved the SEQUENCE before the Alleluia to make sure congregations wouldn’t have to stand during it. (Even worse, everything about the SEQUENCE—including its name—means it should follow the Alleluia.) And imagine endlessly repeating “Alleluia” during Holy Communion at every single Mass. It was all part of an effort to convince people that Holy Communion was historically a procession (which it wasn’t).
    —Jeff Ostrowski
    “Canonic” • Ralph Vaughan Williams
    Fifty years ago, Dr. Theodore Marier made available this clever arrangement (PDF) of “Come down, O love divine” by P. R. Dietterich. The melody was composed in 1906 by Ralph Vaughan Williams (d. 1958) and named in honor of his birthplace: DOWN AMPNEY. The arrangement isn’t a strict canon, but it does remind one of a canon since the pipe organ employs “points of imitation.” The melody and text are #709 in the Brébeuf Catholic Hymnal.
