“Each Mass contains the slaying of the Victim, not repeated here in the West after centuries, made once only long ago in Palestine, yet part of the sacrifice offered throughout the world each morning. All Masses are one sacrifice, including the death of the cross, continuing through all time the act of offering then begun … Every time we hear Mass we look across that gulf of time, we are again before the cross, with his mother and St. John; we offer still that victim then slain, present here under the forms of bread and wine.”
— Fr. Adrian Fortescue (d. 1923)

published 8 December 2017 by Jeff Ostrowski

3683 Immaculate ELOW, you will find the booklet for the Immaculate Conception, which I first posted several years ago. We had a “Schola Mass” at FSSP.la today—nothing but plainsong—which we do when our choir of 40 voices gets a day off. I printed the booklets, but made some last minute changes at the Church. We substituted for Mass II a mixture of Mass IV and Mass X, which was easily done since the Campion Hymnals contain the full KYRIALE. We also ended up using the Chants Abrégés version of the Gradual, which was easily accomplished since those are in the Goupil Graduals.

But it’s still nice to have these booklets (even when we are inspired to make last-minute changes) because we know that no matter what happens, we can sing the entire Mass from the booklet:


It struck me today—while singing the Introit—how powerful it is to have the English underneath each Latin word. (This is done for all the scores at the René Goupil website.) My knowledge of Latin is halfway decent, but while singing the notes I’m so glad to look under each word for a reminder. The Introit for today is not extremely familiar to me, but the musical phrases make a lot more sense when we understand their meaning.

In that booklet, you’ll see a splendid piece with these words:

He whom the whole world cannot contain was enclosed in thy womb…

We sang it during the Offertory incensation.


The priest who gave the homily said this feast was originally called “the feast of the Conception of Saint Anne.”
