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.

    Dom Pothier • Photo from 1904
    Dom Paul Cagin, in a 1904 publication (L’oeuvre de Solesmes dans la restauration du chant grégorien) made sure to include a beautiful image of Dom Pothier, the legendary abbot of St-Wandrille. Also shown is a very young Dom André Mocquereau. Auguste Pécoul—considered the spiritual “son” of Abbat Prosper Guéranger of Solesmes—wrote as follows on 24 June 1901: “To forestall any confusion, let us remember that there is just one Gregorian notation—that restored, according to the ancient manuscripts, by the eminent Abbot of Saint-Wandrille, Dom Pothier.” ✠

    PDF • “3-Voice Motet” (Father De Laet)
    I believe 99% of our readers will recognize this hymn tune. Perhaps Father Edgard De Laet should have called it a ‘hymn’ instead of a ‘motet for three voices’—but he’s technically correct, since MOTET is defined as: “a short piece of sacred choral music, typically polyphonic and unaccompanied.” The even verses are for three voices, as you will see if you download the PDF score at #20245. The odd verses may be song a cappella SATB or unison with organ.

    PDF Download • “Hymn for 2 Voices”
    Readers who click on this video will see that it starts with verses of the “Pange Lingua” hymn by Saint Thomas Aquinas (d. 1274) arranged for two voices. However, there’s a polyphonic refrain (“Tantum Ergo”) for three voices, taken from Kevin Allen’s Motecta Trium Vocum. If your choir is very small, this piece is for you! You can download the PDF score free of charge—and you can also utilize the rehearsal videos for each individual voice—by navigating yourself to #20323.

Quick Thoughts

    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.”

    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

“…it would be a very praiseworthy thing and the correction would be so easy to make that one could accommodate the chant by gradual changes; and through this it would not lose its original form, since it is only through the binding together of many notes put under short syllables that they become long without any good purpose when it would be sufficient to give one note only.”

— Zarlino (1558) anticipating the Medicæa
