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.”

How I Learned What Liturgy Really Is

Congregations in South Texas normally applaud for the musicians during Mass.

More unites us than divides us!

Musicians tend to be very “picky” people who don’t get along with one another.

Proclaim the Passion in a “Theatrical” Manner?

Scripture at Mass is an act of worship: it is not purely didactic, nor is it a make-believe drama that we must re-enact with emotion.

To be absolutely clear: President Barack Obama is not the Second Person of the Blessed Trinity.

Reform Of The Reform: A Perspective

“How much annoyance among our loyal Catholics could have been avoided if evidence had been provided that various elements had been taken from old sacramentaries and were not arbitrary innovations.” —Bishop of Regensburg (1979)

Ratzinger: “How much filth there is in the church!”

“Have mercy on your church,” Cardinal Ratzinger prayed in 2005. “When we fall, we drag you down to earth, and Satan laughs, for he hopes that you will not be able to rise from that fall; he hopes that being dragged down in the fall of your church, you will remain prostrate and overpowered.”

There is no mention in Apostolicam Actuositatem of running bake sales or pulling bingo numbers.

Aren’t Altar Missals Required To Print The Latin Alongside The English?

Are we “the most highly educated laity in the history of the church” capable of making our moral decisions without substantive Church guidance … or are we idiots who can’t figure out what “dew” is?

Jeff Ostrowski · December 29, 2013

Bugnini Wanted To Eliminate Ash Wednesday!

They failed to realize that one cannot simply “sit down over tea and crumpets” and VOTE INTO BEING the Church calendar. It’s supposed to develop organically.

President’s Corner

    “Sanctus VIII” • Organ Accompaniment
    A few days ago, I composed this organ harmonization for SANCTUS VIII. This Mass is traditionally called Missa de ángelis or “Mass of the angels.” In French, it is Messe de Anges. You can evaluate my attempt to simultaneously accompany myself on the pipe organ (click here) while singing the melody. My parish is currently singing this setting.

    Music List • (5th Sund. Ordinary Time)
    Readers have expressed interest in perusing the ORDER OF MUSIC I’ve prepared for this coming Sunday, 8 February 2026, which is the 5th Sunday in Ordinary Time (Year A). If such a thing interests you, feel free to download it as a PDF file. You will probably notice it isn’t as ‘complete’ or ‘spiffy’ as usual, owing to some difficulties which took place this week.
    —Jeff Ostrowski
    PDF • “Communion” (5th Sunday in Ordin.)
    The COMMUNION ANTIPHON for this coming Sunday, 8 February 2026—which is the 5th Sunday in Ordinary Time (Year A)—is truly delightful. You can download the musical score completely free of charge. This text will be familiar to altar boys, because it’s PSALM 42. The Feder Missal makes the following claim about that psalm: “A hymn of a temple musician from Jerusalem: he is an exile in a heathen land, and he longs for the holy city and his ministry in the Temple there. The Church makes his words her own.”
    —Jeff Ostrowski

Quick Thoughts

    “Reminder” — Month of Febr. (2026)
    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. It couldn’t be easier to subscribe! Just scroll to the bottom of any blog article and enter your email address.

    PDF Chart • “Plainsong Rhythm”
    I will go to my grave without understanding the lack of curiosity so many people have about the rhythmic modifications made by Dom André Mocquereau. For example, how can someone examine this single sheet comparison chart and at a minimum not be curious about the differences? Dom Mocquereau basically creates a LONG-SHORT LONG-SHORT rhythmic pattern—in spite of enormous and overwhelming manuscript evidence to the contrary. That’s why some scholars referred to his method as “Neo-Mensuralist” or “Neo-Mensuralism.”
    —Jeff Ostrowski
    PDF • “O Come All Ye Faithful” (Simplified)
    I admire the harmonization of “Adeste Fideles” by David Willcocks (d. 2015), who served as director of the Royal College of Music (London, England). In 2025, I was challenged to create a simplified arrangement for organists incapable of playing the authentic version at tempo. The result was this simplified keyboard arrangement (PDF download) based on the David Willcocks version of “O Come All Ye Faithful.” Feel free to play through it and let me know what you think.
    —Jeff Ostrowski

Random Quote

“Is it not true that prohibiting or suspecting the extraordinary form can only be inspired by the demon who desires our suffocation and spiritual death?”
