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.”

    Music List • (4th Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I created for this coming Sunday, which is the 4th Sunday of Lent (15 March 2026). If such a thing interests you, feel free to download it as a PDF file. This feast has sublime propers. It is most often referred to as “Lætare Sunday” owing to its INTROIT. I encourage all the readers to visit the feasts website, where the Propria Missae may be downloaded completely free of charge.

    PDF Download • Communion (4th Snd. Lent)
    The COMMUNION ANTIPHON for this coming Sunday, which is the Fourth Sunday of Lent (Year A), is particularly beautiful. There’s something irresistible about this tone; it’s neither happy nor sad. As always, I encourage readers to visit the flourishing feasts website, where the complete Propria Missae may be downloaded free of charge.

    Good Friday Flowers
    Good Friday has a series of prayers for various parties: the pope, catechumens, pagans, heretics, schismatics, and so forth. In the old liturgical books, there was no official ‘name’ for these prayers. (This wasn’t unusual as ‘headers’ and ‘titles’ for each section is a rather modern idea.) The Missal simply instructed the priest to go to the Epistle side and begin. In the SHERBORNE MISSAL, each prayer begins with a different—utterly spectacular—flower. This PDF file shows the first few prayers. Has anyone counted the ‘initial’ drop-cap flowers in the SHERBORNE MISSAL? Surely there are more than 1,000.

Quick Thoughts

    “Dies Irae” • A Monstrous Translation
    It isn’t easy to determine what Alice King MacGilton hoped to accomplish with her very popular book—A Study of Latin Hymns (1918)—which continued to be reprinted in new editions for at least 34 years. This PDF file shows her attempt to translate the DIES IRAE “in the fewest words possible.” There’s a place for dynamic equivalency, but this is repugnant. In particular, look what she does to “Quærens me sedísti lassus.”
    —Jeff Ostrowski
    PDF Download • “Holy, Holy, Holy”
    For vigil Masses on Saturday (a.k.a. “anticipated” Masses) we use this simpler setting of the “Holy, Holy, Holy” by Monsignor Jules Vyverman (d. 1989), a Belgian priest, organist, composer, and music educator who ultimately succeeded another ‘Jules’ (CANON JULES VAN NUFFEL) as director of the Lemmensinstituut in Belgium. Although I could be wrong, my understanding is that the LEMMENSINSTITUUT eventually merged with “Catholic University of Leuven” (originally founded in 1425). That’s the university Fulton J. Sheen attended.
    —Jeff Ostrowski
    Grotesque Pairing • “Passion Chorale”
    One of our rarest releases was undoubtably this PDF scan of the complete Pope Pius XII Hymnal (1959) by Father Joseph Roff, a student of Healey Willan. One of the scarcest titles in existence, this book was provided to us by Mr. Peter Meggison. Back in 2018, we scanned each page and uploaded it to our website, making it freely available to everyone. Readers are probably sick of hearing me say this, but just because we upload something that doesn’t necessarily mean it’s wonderful or worthy of imitation. We upload many publications precisely because they are ‘grotesque’, interesting, or revealing. Whereas the Brébeuf Catholic Hymnal had an editorial board that was careful and sensitive vis-à-vis pairing texts with tunes, the Pope Pius XII Hymnal (1959) seems to have been rather reckless in this regard. Please take a look at what they did with the PASSION CHORALE and see whether you agree.

Random Quote

[to the executioner] Sir Thomas More: “I forgive you right readily.” [gives him a coin] “Be not afraid of your office; you send me to God.” Archbishop Cranmer: “You’re very sure of that, Sir Thomas?” More: “He will not refuse one who is so blithe to go to him.” [kneeling, he places his head on the chopping block]

— From “A Man for All Seasons” (1960 play by Robert Bolt)
