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.”

Poverty, Self-Denial, and Peace – Part II

How do we learn the art of self-denial? In small steps that prepare us for the ultimate step: surrendering our soul to the Lord at death.

Dr. Peter Kwasniewski · January 30, 2014

Poverty, Self-Denial, and Peace – Part I

The remedy for disordered desire is mortification and the longing for God, the living God, who calls us to intimate union. How different is Christian redemption from a Buddhist annihilation of self!

Dr. Peter Kwasniewski · January 23, 2014

Lord, Deliver Me From My Persecutors

It is only a matter of time before being a Catholic at all will involve renouncing much that the world considers important and necessary. And soon there will be open persecution. Are we ready?

Liturgical Abuse and Abuse of Minors

The decades-long abuse of the sacred liturgy—and therefore, of faithful Catholics who have a right to the sacred liturgy in its fullness—constitutes the first and fundamental form of clerical abuse of the laity, of which sexual abuse is a particular and more demented moral variety.

Dr. Peter Kwasniewski · January 9, 2014

Byzantine Splendor and Roman Sobriety

The traditional Western Mass is intent on reminding the worshiper of the death of Christ and the believer’s own sinfulness and unworthiness, while the Eastern Divine Liturgy accents the victory of Christ and the Christian’s triumph with Him in glory.

Dr. Peter Kwasniewski · January 2, 2014

‘Medieval’ Liturgy and ‘Scholastic’ Theology

The prejudice against the ancient (or, in many respects, medieval) Roman Rite is quite similar to the long-fashionable prejudice against scholastic philosophy.

Dr. Peter Kwasniewski · December 19, 2013

Prayer and Action

If we want our apostolate or our daily round of duties to be fruitful, we need to begin and end with the continually burning fire of adoring union with God.

Dr. Peter Kwasniewski · December 12, 2013

General and Particular Examen

Many saintly authors recommend a “particular and general examination of conscience,” but seldom explain what is meant by this, apparently because it used to be extremely well known.

Dr. Peter Kwasniewski · December 5, 2013

Recovering the Greatness of the Roman Rite

Why did we suppress the most precious, most beautiful gift the Lord had given to us? What were we thinking? A child’s perspective brings out the importance of the solemn sung liturgy.

Dr. Peter Kwasniewski · November 28, 2013

Spiritual Reading

Do you have a plan about which spiritual book you will be reading this Advent?

Dr. Peter Kwasniewski · November 21, 2013

Is the Mass “Just” the Mass?

It is too easy to fall into the trap of thinking that nothing else matters in the liturgy besides “Jesus is present.” This is a superficial and relativistic way of thinking that has to be challenged and corrected, if the Real Presence is to be of any benefit to us—indeed, if our faith in the Real Presence is even going to survive.

Dr. Peter Kwasniewski · November 14, 2013

A Sober Assessment of Liturgical Reform

The official statements always sing the praises of reform, but the people in the pews know better. They are the ones who have suffered the most.

Dr. Peter Kwasniewski · November 7, 2013

The Fear of the Lord

Do we rightly fear the Lord?

Incarnation and Divinization

Why did the Son of God become man? “God became man, that men might become gods” (St. Athanasius).

On Aweful Ambos and Lilliputian Lecterns

Why can’t churches have grand furnishings and fixtures—like the lofty pulpits you see in older churches? And why aren’t those pulpits, where they exist, still being used today?

    PDF Download • “For Pentecost Sunday”
    Yesterday morning, I recorded myself singing the ENTRANCE CHANT for Pentecost Sunday while simultaneously accompanying myself on the pipe organ. Click here to see how that came out. At the end of the antiphon, there’s a triple Allelúja and I just love the chord at the end of the 2nd iteration. The organ accompaniment—along with the musical score for singers—can be downloaded free of charge at the flourishing feasts website. For the record, the antiphon on Pentecost Sunday doesn’t come from a psalm; it comes from the book of Wisdom.

    PDF Download • “Organ Accompaniment”
    Over the past few years, I’ve been harmonizing all the vernacular plainsong Introit settings by the CHAUMONOT COMPOSERS GROUP. This coming Sunday—10 May 2026—is the 6th Sunday of Easter (Year A). The following declaration will probably smack of “blowing my own horn.” However, I’d rank this accompaniment as my best yet. In this rehearsal video, I attempt to sing it while simultaneously accompanying myself on the pipe organ. The musical score [for singers] as well as my organ accompaniment can be downloaded free of charge from the flourishing feasts website.

    “Gregorian Chant Quiz” • 4 May 2026
    A few days ago, the CORPUS CHRISTI WATERSHED Facebook page posted this Gregorian Chant quiz regarding a rubric for the SEQUENCE for the feast of Corpus Christi: “Lauda Sion Salvatórem.” There is no audience more intelligent than ours—yet surprisingly nobody has been able to guess the rubric. Drop me an email with the right answer, and I’ll affirm your brilliance to everyone I encounter!

Quick Thoughts

    “Thee” + “Thou” + “Thine”
    Few musicians realize that various English translations of Sacred Scripture were granted formal approval by the USCCB and the Vatican for liturgical use in the United States of America. But don’t take my word for it! Here are four documents proving this, which you can examine with your own eyes. Some believe the words “Thine” and “Thou” and “Thee” were forbidden after Vatican II—but that’s incorrect. For example, they’re found in the English translation of the ‘Our Father’ at Mass. Moreover, the Revised Standard Version (Catholic Edition) mentioned in those four documents employs “Thine” and “Thou” and “Thee.” It was published with a FOREWORD by Westminster’s Roman Catholic Archbishop (John Cardinal Heenan).

    “Reminder” — Month of May (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.

    Simplified Version • “Canon in D” (Pachelbel)
    I published an article on 11 November 2023 called Wedding March For The Lazy Organist, which rather offhandedly made reference to a simplified version I created in 2007 for Pachelbel’s Canon. I often use it as a PROCESSIONAL for weddings and quinceañeras. Many organists say they “hate” Pachelbel’s Canon. But I love it. I think it’s bright and beautiful. I created that ‘simplified version’ for musicians coming to grips with playing the pipe organ. It can be downloaded as a free PDF if you visit Andrea Leal’s article dated 15 August 2022: Manuals Only: Organ Interludes Based on Plainsong. Specifically, it is page 84 in that collection—generously offered as a free PDF download. Johann Pachelbel (d. 1706) was a renowned German organist, violinist, teacher, and composer of over 500 works. A friend of Bach’s family, he taught Johann Christoph Bach (Sebastian Bach’s eldest brother) and lived in his house. Those who read Pachelbel’s biography will notice his connection to two German cities adopted as famous hymn tune names: EISENACH and ERFURT.

Random Quote

“We want to say something very plainly to those whose shallow minds or unthinking passion for the new lead them to the idea that the Latin language must be totally spurned by the Latin Church. To them we say that it is absolutely clear that Latin must be held in high honor and especially for the excellent and serious reasons that we have mentioned.”

— Pope Saint Paul VI (26 April 1968)
