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.”

Re: Ancient Sequence (Thursday after Pentecost)

Jeff Ostrowski · May 29, 2023

ERONICA MORENO recently published a fascinating article called: Terrific Pentecost Hymn You’ve Not Heard Before! Basically, Veronica spoke about the ancient Sequence for Pentecost Thursday called: Qui Procédis Ab Utróque. Veronica provided quite a bit of information. For example, she posted a PDF organ accompaniment—99 pages!—by HENRI POTIRON (professor at the Gregorian Institute in Paris) which contains an accompaniment for that Sequence. Veronica also provided a peerless metrical translation by MONSIGNOR RONALD KNOX, which is #710 in the Brébeuf Portal. She also posted rehearsal videos, a mediæval manuscript, background for the ALLES IST AN GOTTES SEGEN tune, and other interesting items.

FSSP Priest Enters! • A member of the Priestly Fraternity of Saint Peter saw the article and was inspired to create—for the first time in history—a literal translation into English:

Qui procédis ab utróque,
Genitóre Genitóque,
Páriter Paráclite.
Redde linguas eloquéntes,
Fac fervéntes in te mentes
Flamma tua dívite.

Thou who procedest equally from each,
Father and Son,
O Paraclete:
render tongues rich in speech,
make minds glow for thee
through thy lavish flame.

Amor Patris Filiíque,
Par ambórum et utríque
Compar et consímilis.
Cuncta reples, cuncta foves,
Astra regis, caelum moves,
Pérmanens immóbilis.

Love of the Father and Son,
equal of both, and to each
matched and alike:
all thou fillest, all thou tendest,
stars thou rulest, heaven thou movest,
all unmoving thou remaining.

Lumen carum, lumen clarum,
Internárum tenebrárum
Éffugans calíginem.
Per te mundi sunt mundáti:
Tu peccátum, tu peccáti
Déstruis rubíginem.

Light beloved, light radiant,
putting to flight the obscurity
of inward shadows:
the clean by thee are cleansed:
thou sin, and thou sin’s
rust destroyest.

Veritátem notam facis,
Et osténdis viam pacis,
Et iter justítiae.
Perversórum corda vitas,
Et bonórum corda ditas
Múnere sciéntiae.

Truth thou makest known,
thou showest both the way of peace
and the course of justice.
The hearts of the depraved thou shunnest,
and the hearts of the good thou enrichest
with the gift of knowledge.

Te docénte nil obscúrum,
Te regénte nil impúrum
Sub tua praeséntia.
Gloriátur mens jucúnda
Per te laeta; per te munda
Gaudet consciéntia.

With thy teaching naught is darksome,
with thy ruling naught is sullied
beneath thy gaze
[lit. presence].
The cheerful mind glories,
gladdened by thee; made clean
by thee, conscience rejoices.

Tu commútas eleménta:
Per te suam sacraménta
Habent efficáciam.
Tu nocívam vim repéllis,
Tu confútas et reféllis
Hóstium nequítiam.

Elements thou convertest:
by thee do the sacraments
possess their power.
Harmful force thou drivest away,
thou restrainest and exposest
the wickedness of foes.

Quando venis, corda lenis:
Quando subis, átrae nubis
Éffugit obscúritas.
Sacer ignis, cor fidélis
Intus uris, et a curis
Purgas, quando vísitas.

When thou comest, thou softenest hearts:
when thou enterest, there flees
the dismal cloud’s darkness.
O hallowed fire, the faithful heart
thou burnest within, and from cares
thou clearest, when thou visitest.

Mentes prius imperítas
Et sopítas et oblítas
Érudis et éxcitas.
Foves linguas, formas sonum;
Cor ad bonum facit pronum
A te data cáritas.

Minds hitherto unaware,
both deadened and besmeared
[or in another sense, deceived]
thou refinest and rousest.
Tongues thou tendest, speech thou shapest;
charity, given by thee,
makes the heart inclined to good.

O juvámen oppressórum,
O solámen miserórum,
Páuperum refúgium.
Da contémptum terrenórum,
Ad amórem supernórum
Trahe desidérium.
Amen.

O aid of the downtrodden,
O solace of the wretched,
haven of the poor:
grant
[us] disregard of earthly things,
to the love of things above
draw
[our] longing.
Amen.

Provenance • I believe this Sequence was mainly used in France. You can tell it’s relatively late as it’s written according to rhyme and stress-accent (QuaLitative), rather than long and short syllables (QuanTitative). For more on this, cf. my 2016 article: The “Long & Short” of Latin Hymns.

    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.

    Music List • (1st Sunday of Lent)
    Readers have expressed interest in seeing the ORDER OF MUSIC I’ve prepared for this coming Sunday—22 February 2026—the 1st Sunday of Lent (Year A). If such a thing interests you, feel free to download it as a PDF file. As always, the Responsorial Psalm, Gospel Acclamation, and Mass Propers for this Sunday are available at the outstanding feasts website alongside the official texts in Latin. I spent an enormous amount of time preparing this ORDER OF MUSIC—because the children’s choir will join us—and some of its components came out great. For example, the COMMUNION ANTIPHON with Fauxbourdon is utterly resplendent, yet still ‘Lenten’.
    —Jeff Ostrowski
    2-Voice Arrangement for Lent
    Those seeking a two-voice arrangement for LENT and PASSIONTIDE should click here and scroll down. It’s based on number 775 in the Brébeuf Hymnal, with an enchanting melody written by Kevin Allen (the legendary American composer of sacred music). That text—“Pendens In Crucis Cornibus”—is often used for the Feast of our Lady of Sorrows. That link is important because, in addition to the musical score, it provides free rehearsal videos for each individual voice: something volunteer choirs appreciate!

    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.

Random Quote

“These liturgists protest that the choir must be encouraged, but in the same breath we are told its purpose is to lead the congregation in the singing of hymns and other unison music. These directions from non-musicians who have never created a musical sound—let alone direct a choir—are the cause of consternation among practicing musicians, both instrumentalists and singers.”

— Monsignor Richard J. Schuler (30 November 1967)
