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 Pope Has Prayed About This Decision For A Long Time

We are now learning that our Holy Father had been contemplating and praying about his resignation for a very long time. In April of 2009, the Holy Father visited the tomb of an obscure Pope named St. Celestine V, remarkable for a certain reason . . .

President’s Corner

    Little Encouragement?
    In the Gospel, our Savior tells about 10 lepers who were healed. Only one went back to give thanks. Precious few express gratitude, yet many have endless energy to complain. For that reason, I deeply appreciate receiving messages like the following, which arrived a few days ago (about the parish where I direct in Michigan): “Last Sunday, a couple I knew from Grand Rapids was at Mass at 10:00 a.m. I got a chance to talk to them after Mass. I wanted to let you know what they said about the choir. They were absolutely floored by our sound!!!!! They both said they could continuously listen to our choir and the beauty of it. They asked me: “Do you always sound like that?” And they were also very surprised at how packed the church was. They said it was nice for them to be in such a full church. I just thought you would be interested to know their thoughts about our choir.”
    —Jeff Ostrowski
    (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.

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.
    —Jeff Ostrowski

Random Quote

“Every experienced choirmaster’s work is founded on the following three axioms: (1) Few boys have a really good natural voice; (2) No boy is able to control his voice and produce good tone without training; (3) Most boys have a good ear, and considerable imitative capacity. It is on the last of these axioms that the choirmaster must begin his work.”

— Sir Richard Runciman Terry (1912)
