Our Take

St. Augustine was trying to understand the Trinity one morning as he walked on the beach.

He came across a small child who had dug a hole in the sand. He was taking scoopfuls of water from the ocean with a shell and pouring them into the hole.

“My boy, what are doing?” asked Augustine.

“I am trying to bring all the sea into this hole,” replied the boy.

“But that is impossible, my dear child. The hole cannot contain all that water,” said Augustine.

“It is no more impossible than what you are trying to do,” said the boy. “You cannot comprehend the immensity of the mystery of the Holy Trinity with your small intelligence.”

We human beings always have to be reminded that we can’t understand God.

Moses reminds his hearers of that by piling on questions in the first reading: “Did anything so great ever happen before? Was it ever heard of? Did a people hear the voice of God speaking from the midst of the fire, as you did, and live? Or did any god venture to go and take a nation for himself?"

Like God himself, the Holy Trinity is a mystery — not in the sense of a mystery novel, but in the sense of a “mystery of the Rosary.” It is a sacred reality so immense we can only contemplate it, never fully grasp it.

In the case of the Holy Trinity, God has left some traces of his Trinitarian being in creation and in the Old Testament, says the Compendium of the Catechism, but the Trinity as we know it was definitively revealed by Jesus Christ.

Our children should know how to answer the basic questions about the Trinity: How many Gods are there? One. How many persons in God? Three. But the fact is, we don’t know much more than our children about the Trinity. All of our analogies fall short, because the Trinity is so far above every human imagining. You could say the Trinity is like a chord you play, using three notes to make one unique sound. Or you could say, like is often attributed to St. Patrick, that the Trinity is like a three-leaf shamrock: Three separate entities that make one thing. These images capture in a slight degree the unity and harmony of the Trinity.

“Inseparable in their one substance, the three divine Persons are also inseparable in their activity,” says the Compendium of the Catechism. “The Trinity has one operation, sole and the same.”

But those images don’t capture the relationship that the Persons have with one another — a relationship in which “the Father generates the Son; the Son is generated by the Father; the Holy Spirit proceeds from the Father and the Son.”

To try to explain the relationship of the persons of the Trinity, you could compare it to a family, in which a husband and wife love one other and that love becomes another person. But while that in a small way mirrors the relationship of the Trinity, it loses the concept of their unity.

The best answer to the Trinity is that of another saint, Blessed Elizabeth of the Trinity, who lived from 1880 to 1906 and devoted her life to the Trinity. In her famous prayer, she does not attempt to understand the Trinity. She only surrenders: “O, my three, my all, my beatitude, infinite solitude, immensity in which I lose myself, I surrender myself to you as your possession. Bury yourself in me, that I may bury myself in you until I depart to contemplate in your light the abyss of your greatness.”

Her prayer is like a toddler’s sentiment toward her parents: The toddler doesn’t understand the love of her parents, but she knows she is loved and accepts it. Her love for her parents does for her what the Holy Spirit does for St. Paul in today’s reading: It makes him cry, “Abba, Father!”

We are called to enter into the Trinity’s love, not to fully understand it.

And we are also called to spread that love in Christ.

In today’s Gospel, Jesus assures us that “all power in heaven and on earth has been given to me. Go, therefore, and make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit, teaching them to observe all that I have commanded you.”

We do so not as individuals, but as members of the Trinitarian family.

“And behold, I am with you always, until the end of the age,” Christ reassures us.

That is all we need to know, whether we understand it or not.
