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.”

Alfredo Cardinal Ottaviani (1890-1979)

“The rite of Holy Mass should not be treated as if it were a piece of cloth to be refashioned according to the whim of each generation.”

Veronica Brandt · April 13, 2013

Maternal Heart of Mary Chapel (Sydney, Australia)

The liturgy there is beautiful. Sunday Mass usually begins with a rousing organ prelude. Then the priest intones the Asperges . . .

Does Having Children Make Us Better at Our Jobs?

Working for the Church is often not conducive to family life. But, in my children, I found God. Children have helped me focus on what and who is important.

PDF Download • Instruction on Sacred Music (“De Musica Sacra”) • Issued by Pope Pius XII in 1958

Don’t you hate it when you think you know the answer to something . . . and then you find out you were dead wrong? This happened to me regarding the congregation reciting Mass Propers in the Extraordinary Form.

Why Liturgical Bad Habits Must Be Broken

The Church is not built up and strengthened when her pastors ignore her conciliar teaching, repudiate her tradition, violate her rubrics and instructions, and merrily accept the status quo in all its mediocrity.

Participating Actively despite all of that Active Participation

Isn’t this what is meant by the “active participation” that is one of the liturgical goals of the Second Vatican Council?

The Latin Mass Has Come Such A Long Way!

“The greatest problem of the new missal, at least in English-speaking countries, lay in the miserable translation that was imposed upon priests and people. Many prayers were so mistranslated that a student of first-year Latin would have done better.” — Msgr. Richard Schuler, 1984

“Chronicles of Narnia” by Msgr. Richard Schuler

“The hootenanny Mass can give explicit eucharistic and christological specification to youth’s intense involvement in the movements for racial justice, for control of nuclear weapons, for the recognition of personal dignity.” — “Worship Magazine” (January 1966)

Richard J. Clark · April 5, 2013

Say the Black. Do the Red—with Love.

The road to the ideal must travel through the hearts and minds of real flesh and blood. If in our ministry we are not teaching love, then we have failed.

Dr. Peter Kwasniewski · April 4, 2013

Can Theology and Liturgy Be Divorced?

Truly it would not be presumptuous to say that, in a liturgy completely centered on God, we can see, in its rituals and chant, an image of eternity.

Reflections From The Editor Of The Campion Missal & Hymnal

For the sake of argument, let us pretend the sentence were true. How many times should one read such commentary? Each time one attends Mass? Surely not. Twice, perhaps? Thrice? Would it not be better to leave such commentary to a separate devotional book?

Thoughtful Article On Hymns By Fr. Mark Woodruff

“Professor László Dobzay, writing from a classic Latin Catholic perspective, has made constructive proposals for a re-integration and mutual perfection of the Ordinary and Extraordinary Forms of the Roman Rite.” — Fr. Woodruff

President’s Corner

    Which Mass?
    In 1905, when the Vatican Commission on Gregorian Chant began publishing the EDITIO VATICANA—still the Church’s official edition— they assigned different Masses to different types of feasts. However, they were careful to add a note (which began with the words “Qualislibet cantus hujus Ordinarii…”) making clear “chants from one Mass may be used together with those from others.” Sadly, I sometimes worked for TLM priests who weren’t fluent in Latin. As a result, they stubbornly insisted Mass settings were ‘assigned’ to different feasts and seasons (which is false). To understand the great variety, one should examine the 1904 KYRIALE of Dr. Peter Wagner. One should also look through Dom Mocquereau’s Liber Usualis (1904), in which the Masses are all mixed up. For instance, Gloria II in his book ended up being moved to the ‘ad libitum’ appendix in the EDITIO VATICANA.

    PDF Download • “Atténde Dómine”
    Although it isn’t nearly as ancient as other hymns in the plainsong repertoire, Atténde Dómine, et miserére, quía peccávimus tíbi (“Look down, O Lord, and have mercy, for we have sinned against Thee”) has become one of the most popular hymns for LENT—perhaps because it was included in the famous Liber Usualis of Solesmes. This musical score (PDF file) has an incredibly accurate version in English, as well as a nice version in Spanish, and also the original Latin. Although I don’t claim to have a great singing voice, this morning I recorded this rehearsal video.

    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
