Trinity Sunday 2026
1. From Reputation to Relationship
Today we celebrate Trinity Sunday, and we hear one of the most famous
biblical verses in all of Scripture:
"For God so loved the world that He gave His only Son, so that everyone
who believes in Him might not perish but might have eternal life." (John
3:16).
These words come from a longer conversation Jesus is having with a man named
Nicodemus.
Nicodemus was a respected Pharisee, a religious leader, sincere and
thoughtful, who wanted to understand who Jesus really was. He had heard about
Jesus. He knew Jesus' reputation. But he did not yet fully recognize who Jesus
was.
And sometimes we are not so different.
We approach God with our own expectations. We want God to fit our categories.
We want Him to confirm what we already think.
But Jesus leads Nicodemus beyond those expectations.
Jesus says:
"You must be born from above."
Nicodemus immediately interprets those words in an earthly way:
"How can a grown man enter his mother's womb again?"
He hears the words, but misses the deeper reality.
And that is part of the challenge of Trinity Sunday.
We can memorize doctrines. We can pray in the name of the Father, and of the
Son, and of the Holy Spirit. But the Trinity is not merely information about
God.
The Trinity is God inviting us into communion with Himself.
2. Learning to Recognize the Call
Sometimes recognizing a call is more difficult than we expect.
Many years ago, in the mid-1990s, I went to a restaurant and was handed one
of those wireless paging devices that would alert me when my table was ready.
At that time I had never seen such a thing before.
I brought it back to my seat and rested my hand on it.
A few minutes later it suddenly started vibrating violently.
For a split second I thought the room was moving. I wondered if there was an
earthquake or if something had happened to the chair.
Then I realized what was happening.
The device was calling me.
The signal had come in, but I did not yet understand what it meant.
In some ways, that is the spiritual life.
God is constantly calling us:
through Scripture,
through prayer,
through conscience,
through suffering,
through the sacraments,
and through other people.
But sometimes we do not recognize the signal.
Nicodemus hears Jesus speaking, but he does not yet understand what Jesus is
telling him.
The call has come in, but he is still learning how to respond.
And perhaps that is true for all of us.
3. God's Name and the Mystery Beyond the Name
That brings us to the first reading from Exodus.
Moses has returned to Mount Sinai after the disaster of the golden calf. The
people had grown impatient and turned toward an idol.
There God proclaims His name:
"A merciful and gracious God, slow to anger and rich in kindness and
fidelity."
This is one of the great moments of the Old Testament because God reveals
who He is.
And it reminds me of something that happens in many families and workplaces.
Have you ever had a parent call you by the wrong name?
Perhaps your mother wanted to call one child and accidentally said another
child's name first.
Or have you ever called one of your co-workers by the wrong name?
I do this all the time. Just ask the staff in the rectory.
Usually that does not happen because we have forgotten who the person is.
Quite the opposite.
It often happens because those people belong to the same circle of
friendship, familiarity, affection, and love.
The name matters because the relationship matters.
But the relationship is greater than the name.
Something similar is true in our relationship with God.
God reveals His name to Moses.
Jesus teaches us to call God "Father."
We are baptized in the name of the Father, and of the Son, and of the Holy
Spirit.
These names truly reveal God.
But they do not exhaust Him.
God's revelation begins with words, but goes beyond words.
God is always greater than what we can fully understand.
That is why the Trinity is not simply a formula to memorize.
The Trinity is a mystery to enter.
4. A God Who Continues to Call
The people at Sinai did not fully understand God.
Nicodemus did not fully understand Jesus.
And we often do not fully understand God's work in our own lives.
Yet God continues calling.
This past week I celebrated another anniversary of my ordination as a
priest.
Over the years I have reflected often on what it means to be called.
Certainly there was study, formation, and preparation.
But vocation is deeper than preparation.
God calls us long before we fully understand what He is doing.
And that is true not only for priests.
Husbands and wives are called.
Parents are called.
Every Christian is called.
Discipleship is not a one-time response.
It is ongoing.
God never stops calling us toward Himself.
5. The Communion of the Holy Trinity
Ultimately, the Trinity is not a puzzle to solve.
The Trinity is the life of God into which we are invited.
As Saint Paul says:
"The grace of the Lord Jesus Christ,
and the love of God,
and the communion of the Holy Spirit be with all of you."
The Father calls us.
The Son saves us.
The Holy Spirit draws us into communion with the living God.
God never stops calling us beyond our sins.
Beyond our disappointments.
Beyond our wounds.
Beyond the limits we place on ourselves.
Calling us into the communion of the Father and the Son and the Holy Spirit.
Why?
What is all of this for?
Who is it for?
Today we can hear the Gospel not only as a message to the world in general,
but personally:
"For God so loved YOU that He gave His only Son for you, so that you
might not perish but might have eternal life."
