What is the Place of the Horizontal Episema in Dom Mocquereau’s Theory?

Dr. Charles Weaver · February 5, 2024

It really is a minor part of Mocquereau’s theoretical enterprise. That doesn’t mean it’s completely pointless, though.

PDF Download • “Rubric Challenge”

The feast of Corpus Christi is special for TLM altar boys. On that day, two of us thurifers got to walk backwards while using the THURIBLE. (That American custom, if memory serves, is not strictly described in the rubrics.) A few weeks ago on the CCW Facebook Page we posted this screenshot from a 1915 Roman Catholic hymnal. The challenge is to guess what the rubric says, which we blocked from view with a red box. So far, nobody has guessed correctly. Feel free to guess! Our email address and phone number is listed at the bottom of each page.

Music List • “Trinity Sunday” (Year A)

Readers have expressed interest in seeing the ORDER OF MUSIC I created for Trinity Sunday—a.k.a. “Dominica I post Pentecosten”—which is 31 May 2026. Please feel free to download it as a PDF file if that appeals to you. The hymns chosen are fairly traditional, but truly excellent (the Communion hymn especially stands out). The ENTRANCE CHANT radiates pure bliss, overflowing with joy.

“Entrance Chant” • Feast of Corpus Christi

While simultaneously accompanying myself on the pipe organ, I recently recorded the INTROIT (“Entrance Chant”) for the feast of Corpus Christi, Years ABC. A whole crop of musical scores—which you really should investigate—have found a home at the flourishing feasts website.

“Reminder” — Month of June (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). Since we were founded in 2006, not one of our board members has ever accepted any renumeration whatsoever—not a penny. 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.

“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).

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.
