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.”

Digitizing the Vatican Library

Fr. David Friel · January 15, 2020

Manuscript pageORKING with manuscripts has long been a labor limited to those with the time and resources to travel to libraries around the globe. In recent years, this has slowly begun to change, as more and more libraries have begun to make their collections available online. Such digitization projects are complex, so publishing an entire library online does not happen overnight. One very important collection that continues to expand its online offerings is the Vatican Apostolic Library (VAT).

Launched in 2010, the digitization of the Vatican Library (known as DigiVatLib and available here) has comprehensive goals. Ultimately, the plan is to make the library’s entire manuscript collection available online. The collection includes 80,000 codices, which will translate to 40 million scanned images. The DigiVatLib project makes use of International Image Interoperability Framework (IIIF) technology, which not only makes its own resources accessible, but also enables these resources to be easily searched and compared alongside the treasures of other major collections.

Digitizing manuscript libraries serves two principal purposes. First, it accomplishes long-term preservation of the materials for future generations. Second, it opens the collection’s treasures to a broad audience of scholars and interested parties. Both of these missions are immensely valuable.

Perusing the Vatican collection online turns up not only mesmerizing manuscripts, but also a large collection of coins and medals. Other treasures to be explored include incunabula, archival materials, and graphic and printed materials.

The homepage of the Vatican Library is worth a visit in its own right, but the digital collections warrant special exploration. One decade into the project, the results are fascinating.

Taking a few moments (or countless hours!) to pore over DigiVatLib is sure to provoke questions, curiosities, and new interests.

    “Music List” • Christ the King Sunday
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 23 November 2025, which is the 34th Sunday in Ordinary Time (Year C). If such a thing interests you, feel free to download it as a PDF file. In the 1970 Missal, this Sunday is known as: Domini Nostri Jesu Christi Universorum Regis (“Solemnity of Our Lord Jesus Christ, King of the Universe”). As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are conveniently stored at the magnificent feasts website alongside the official texts in Latin.

    “Simplified” Keyboard Accompaniment (PDF)
    I’d much rather hear an organist play a simplified version correctly than listen to wrong notes. I invite you to download this simplified organ accompaniment for hymn #729 in the Father Brébeuf Hymnal. The hymn is “O Jesus Christ, Remember.” I’m toying with the idea of creating a whole bunch of these, to help amateur organists. The last one I uploaded was downloaded more than 1,900 times in a matter of hours—so there seems to be interest in such a project. For the record, this famous text is often married to AURELIA, as it is in the Brébeuf Hymnal. The lyrics come from the pen of Father Edward Caswall (d. 1878), an Oratorian priest.

    ‘Bogey’ of the Half-Educated: Paraphrase
    Father Adrian Porter, using the cracher dans la soupe example, did a praiseworthy job explaining the difference between ‘dynamic’ and ‘formal’ translation. This is something Monsignor Ronald Knox explained time and again—yet even now certain parties feign ignorance. I suppose there will always be people who pretend the only ‘valid’ translation of Mitigásti omnem iram tuam; avertísti ab ira indignatiónis tuæ… would be “You mitigated all ire of you; you have averted from your indignation’s ire.” Those who would defend such a translation suffer from an unfortunate malady. One of my professors called it “cognate on the brain.”

Quick Thoughts

    “Reminder” — Month of November (2025)
    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.

    Gospel Options for 2 November (“All Souls”)
    We’ve been told some bishops are suppressing the TLM because of “unity.” But is unity truly found in the MISSALE RECENS? For instance, on All Souls (2 November), any of these Gospel readings may be chosen, for any reason (or for no reason at all). The same is true of the Propria Missæ and other readings—there are countless options in the ORDINARY FORM. In other words, no matter which OF parish you attend on 2 November, you’ll almost certainly hear different propers and readings, to say nothing of different ‘styles’ of music. Where is the “unity” in all this? Indeed, the Second Vatican Council solemnly declared: “Even in the liturgy, the Church has no wish to impose a rigid uniformity in matters which do not implicate the faith or the good of the whole community.”

    “Our Father” • Musical Setting?
    Looking through a Roman Catholic Hymnal published in 1859 by Father Guido Maria Dreves (d. 1909), I stumbled upon this very beautiful tune (PDF file). I feel it would be absolutely perfect to set the “Our Father” in German to music. Thoughts?

Random Quote

“Angularis fundamentum” is typically sung at the dedication or consecration of a church and on church anniversaries. For constructions too numerous to list in recent generations, it would be more appropriate to sing that Christ had been made a temporary foundation. A dispirited generation built temporary housing for its Lord, and in the next millnenium, the ease of its removal may be looked back upon as its chief virtue.

— Fr. George Rutler (2016)
