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.”

Homily: Most Holy Trinity (Year A)

Guest Author · June 14, 2014

0319_charge_to_Peter-crp He said to him the third time, “Simon, son of John, do you love me?” HENEVER someone lets us know intimate and deep secrets about them, it shows that they must have great trust in us and that we must be very dear and special to them. We just don’t share intimate and deep secrets about ourselves at random and without a good reason.

The nature of God. Our reason tells us that we can come to the knowledge of the existence of a God, of some supreme being who is ultimately responsible for the making of the world. Our Catholic faith also teaches us that this is possible. But our unaided reason would never be able to come to the knowledge of the fact that God is a Triune God, that is, that the One God is also the Father, Son, and Holy Spirit. We only know this primarily through the revelation of Jesus, the Second of these persons. We know this through what has been written in the inspired writings of what we call the New Testament and what the Church has defined and explained for us in its authentic teaching of Tradition.

A Mystery: In spite of all we might know, much still remains a mystery, in other words, something that we cannot explain. We accept it on Faith by the Divine gift of Faith. We accept the Catholic Church’s authentic exposition or presentation of this, especially as it is presented in its infallible Creeds. The best presentation or way of expressing this teaching is simply to say that in the One God there are Three Persons Who are equally God, equally sharing or being all the Divine attributes that we can think of ascribing to them. And yet we know that we will never fully understand this Divine nature. Really only a Divine nature could understand a Divine Nature. And by definition a Divine nature can only be one.

We are privileged: And yet as I said at the beginning we are privileged to know of this great mystery because God deemed us worthy to let us in on this great mystery about Him. He certainly didn’t have to. Actually in the entire Old Testament, God never explicitly or clearly revealed His Triune nature. From what we know from the New Testament, we might see some veiled references in the Old Testament. But that is about all they are. We can conjecture as to why God waited till New Testament times clearly to reveal this aspect of Himself. Many saints and Christian writers have done so. That is well and good, but they still remain conjectures.

Today’s Feast. Today we are given the opportunity in a special way to honor and adore the Holy Trinity by celebrating this Feast. (Actually we do this especially in the Traditional Mass on most Sundays when we use the preface of the Most Holy Trinity.) Each sign of the Cross, each Gloria Patri that we say or sing is in honor of the Holy Trinity. We should consider it a real privilege and honor to be able and allowed to honor and praise the Holy Trinity. Without actually saying so, I sometimes think some people almost think they are doing God a favor when they pray or go to Mass. It’s as if they are taking one of their hours and giving it back to God. They don’t seem to realize that it is God that gives us all one hundred and sixty-eight hours every week. We are not really being that generous if all we are willing to give is one hour, plus a few minutes here and there for a few scattered prayers.

Conclusion: God did not have to let us know that He is a triune God. Notice the Introit for today where it tells us to bless and praise the Trinity. What does it give as the reason? “Because He has shown His mercy to us.” Yes, when we sin, we are offending the Most Holy Trinity. Perhaps the amount of forgiveness we will receive will depend on how much we have honored the Most Holy Trinity.


We hope you enjoyed this homily by Fr. Valentine Young, OFM.

    “Reminder” — Month of April (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 Accompaniment (Easter Hymn)
    Number 36 in the Brébeuf Hymnal is “At the Lamb’s high feast we sing,” an English translation for Ad Cenam Agni Próvidi (which was called “Ad Régias Agni Dapes” starting 1631). As of this morning, you can download a simplified keyboard accompaniment for it. Simply click here and scroll to the bottom. Many organists are forced to serve simultaneously as both CANTOR and ACCOMPANIST. In spite of what some claim, this can be difficult—which explains why choirmasters appreciate these simplified keyboard accompaniments. Sadly, many readers will click that link but forget to scroll to the bottom where the simplified PDF file is located.

    PDF Download • “Quasi Modo Sunday”
    The Introit for “Quasi Modo Sunday” (12 April 2026) is particularly beautiful. The musical score can be downloaded as a PDF file, and so can the organ accompaniment. The official language of the Catholic Church is Latin (whereas Greek is our mother tongue). Vatican II said Gregorian Chant must be given “first place” under normal circumstances. As a result, some parishes will rightly sing the authentic version. On the other hand, because so many USA dioceses disobey the mandate of Vatican II, some musicians sing plainsong in the vernacular. I have attempted to simultaneously accompany myself on the pipe organ while singing the English version. Although very few take advantage of it, the complete Proprium Missae is posted at the flourishing feasts website.

Quick Thoughts

    PDF Download • “Anima Christi”
    I received a request for an organ accompaniment I created way back in 2007 for the “Anima Christi” Gregorian Chant. You can download this PDF file which has the score in plainsong followed by a keyboard accompaniment. Many melodies have been paired with “Anima Christi” over the centuries, but this is—perhaps—the most common one.

    PDF • “Liturgical Law” (467 Pages)
    On Good Friday during the middle ages, the pope privately recited THE ENTIRE PSALTER. If you don’t believe me, see for yourself by reading this passage by Dom Charles Augustine Bachofen (d. 1943). His famous book—called “Liturgical Law: A Handbook Of The Roman Liturgy”—was published by the Benjamin Herder Book Company, which was the American arm (operating out of St. Louis, Missouri) of one of the world’s most significant Catholic publishers. Dom Charles Augustine Bachofen was born in Switzerland but spent his career between the Benedictine monasteries at Conception (Missouri) and Mount Angel (Oregon). His 1931 masterpiece, Liturgical Law can be downloaded as a PDF file … 467 pages!

    “Gregorian Chant Quiz” • 24 March 2026
    How well do you know your Gregorian hymns? Do you recognize the tune inserted into the bass line on this score? For many years, we sang the entire Mass in Gregorian chant—and I mean everything. As a result, it would be difficult to find a Gregorian hymn I don’t recognize instantly. Only decades later did I realize (with sadness) that this skill cannot be ‘monetized’… This particular melody is used for a very famous Gregorian hymn, printed in the LIBER USUALIS. Do you recognize it? Send me an email with the correct words, and I promise to tell everybody I meet about your prowess!

Random Quote

“Young people have entrusted me with their absolute preference for the Extraordinary Form… […] But, above all, how can we understand—how can we not be surprised and deeply shocked—that what was the rule yesterday is prohibited today? Is it not true that prohibiting or suspecting the Extraordinary Form can only be inspired by the demon who desires our suffocation and spiritual death?”

— Cardinal Sarah to Edward Pentin (23 September 2019)
