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.”

The Tiniest Prayer Books: the Key of Heaven

Veronica Brandt · September 19, 2020

When Jeff Ostrowski mentioned little tiny hand missals in his photo from World War II, I knew I had to show him these tiny treasures. I don’t have much background information on these as they came from secondhand bookshops. They seem to be fairly common, with a few friends on Facebook recognizing them. Some have treasured copies from their grandparents. Both of mine are made in Belgium but bear the names of Australian publishers.

Two copies of Key of Heaven
Two copies of Key of Heaven: 1905 and 1939.

They are in fairly poor condition. One particular seems to have been well used at Mass as the Method of Hearing Mass is particularly stained and worn. To give some idea of the scale, here are some pictures for comparison with some other small books: The Madonna Missal, Manual of the Children of Mary and The Imitation of Mary. Hmmm… quite a Marian theme going on here.

Now, let’s look inside! This first collection of photos comes from the older and smaller of the two. This one is dated 1905. The type is a little smaller and has an elegant red border around each page.

The other one comes from 1939 and has larger type and more illustrations. The front cover is detached and has a crucifix embedded inside with the indulgenced Prayer before a Crucifix printed on the facing flyleaf. It seems to be some sort of Mother of Pearl material used to make the cross. See here for a comparison with a more modern book using white plastic instead.

A quick web search revealed a similar such book under the same title is still available. It doesn’t look quite the same – for one thing this new edition is much larger measuring 6″x4″ whereas these older books are a tiny 4″x2.25″. It sounds like the idea is the same though.

It makes sense, when Mass and the Readings are in Latin, having a portable copy of your own vernacular translation makes sense. I wonder if Fr Gereon Goldman had such a book in German. I’ve heard stories of pocket prayer books or Bibles stopping bullets in wartime. There are even some made with a steel plate cover called Heart Shields.

All this goes to show that people did care about praying the Mass with understanding back in the days before ICEL.

    PDF • “Music List” (4th Sunday of Advent)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for 21 December 2025, which is the 4th Sunday of Advent (Year A). If such a thing interests you, feel free to download it as a PDF file. The ENTRANCE CHANT is the famous “Roráte Coeli” and the fauxbourdon setting of the COMMUNION is exquisite. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the feasts website alongside the official texts in Latin.

    PDF • Our Lady of Guadalupe (12 Dec.)
    The Responsorial Psalm may be downloaded as a PDF file (organist & vocalist) for 12 December, which is the Feast of Our Lady of Guadalupe. When it comes to the formulary for this Mass, it’s astounding how infrequently it’s included in official books. Prior to Vatican II, one had to search through “supplemental material” printed in the back of hand-missals and graduals. But since 1970, the feast is virtually nonexistent. According to the UNIVERSAL KALENDAR, 12 December is the “Feast of Saint Jane Frances De Chantal, Religious” (Die 12 decembris: S. Ioannæ Franciscæ de Chantal, religiosæ). Why should that feast overpower Our Lady of Guadalupe? In the United States, OLG is celebrated—and I’d assume in Mexico, Central America, South America, and Canada—but, as I said, the Propria Missae are virtually impossible to locate. I possess only three books which mention this feast.

    Simplified Accompaniment (Advent Hymn)
    Many organists are forced to simultaneously serve as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult. I invite you to download this simplified organ accompaniment (PDF) which in the Father Brébeuf Hymnal is hymn #661: “Come, Thou Long-Expected Jesus” (for ADVENT). 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 2,900 times in a matter of hours—so there appears to be interest.

Quick Thoughts

    PDF Download • “Santo Santo Santo”
    Those searching for a dignified, brief, simple, bright setting of SANCTUS in Spanish (“Santo Santo Santo”) are invited to download this Setting in honor of Saint John Brébeuf (organist & vocalist). I wonder if there would be any interest in me recording a rehearsal video for this piece.

    Pope Leo XIV on Sacred Music
    On 5 December 2025, Pope Leo XIV made this declaration with regard to liturgical music.

    “Translations Approved for Liturgical Use”
    According to the newsletter for USSCB’s Committee on Divine Worship dated September 1996, there are three (3) translations of the Bible which can be used in the sacred liturgy in the United States. You can read this information with your own eyes. It seems the USCCB and also Rome fully approved the so-called NRSV (“New Revised Standard Version”) on 13 November 1991 and 6 April 1992 but this permission was then withdrawn in 1994.

Random Quote

“In all this mediaeval religious poetry there is much that we could not use now. Many of the hymns are quite bad, many are frigid compositions containing futile tricks, puns, misinterpreted quotations of Scripture, and twisted concepts, whose only point is their twist. But there is an amazing amount of beautiful poetry that we could still use. If we are to have vernacular hymns at all, why do we not have translations of the old ones?”

— Fr. Adrian Fortescue (d. 1923)
