Holy Trinity - Living in the Heart of the Trinity

 

Homily on John 16:12–15 – Living in the Heart of the Trinity

Today’s Gospel, from John brings us into the mystery of God Himself.

Jesus says to His disciples:

“I have much more to tell you, but you cannot bear it now.

But when He comes, the Spirit of truth, He will guide you to all truth.”

It is no coincidence that this passage is often proclaimed as we celebrate Trinity Sunday, the solemn feast of our God—Father, Son, and Holy Spirit.

This is not just a mystery to admire from a distance—it is the very life and love of God that we are invited into.


Let’s begin with the heart of the Trinity: relationship.

God is not a solitary being, distant and aloof.

God is a communion of persons:

the Father who loves,

the Son who is loved and returns that love,

and the Holy Spirit, who is the very bond of that love.

One God, three Divine Persons, eternally united.

Jesus says in today’s Gospel:

“Everything that the Father has is mine; for this reason I told you that He [the Holy Spirit] will take from what is mine and declare it to you.”

There is no competition in the Trinity.

No division.

No selfishness.

Only complete self-giving and sharing.

Each Person gives Himself totally to the other.

This is not a theological abstraction—it is the very nature of God.

Now, here’s the amazing part:

you and I were made in the image of this God.

That means we are made for love, for relationship, for communion—not isolation, not control, not pride.


Let me share a story to help us understand the Trinty.

There was once a missionary priest serving in a small African village.

He had spent many months trying to explain the concept of the Trinity to his catechumens.

He had tried using symbols—the triangle, the shamrock, the three candles in one light—but the people still looked puzzled.

One day, he visited a local family.

It was a grandmother, her daughter, and a small child.

He watched how the grandmother gently helped the mother with cooking, while the mother taught her little girl to carry water.

He saw how they laughed, corrected one another gently, and shared everything—stories, work, even silence.

He suddenly realized: This is the image.

He gathered the catechumens the next day and said,

“The Trinity is like that family.

The grandmother, mother, and daughter—distinct persons, but united by love.

They live for one another, give to one another, and love as one.

That is what God is like.”

And that day, something clicked.

The people nodded.

They understood.

The Trinity is not a math problem to solve.

It is a living relationship.

And it’s one we are invited into.


The Trinity, however, has been Revealed Gradually

Jesus also says in the Gospel:

“I have much more to tell you, but you cannot bear it now.”

That tells us something important: God reveals Himself gradually.

In the Old Testament, God revealed Himself as the One Creator, a loving Father who formed His people.

Then, in the Incarnation, the eternal Son became flesh—Jesus, fully God and fully man.

After His Resurrection and Ascension, the Holy Spirit was sent to dwell in the hearts of believers.

Why doesn’t God reveal everything at once?

Because He meets us where we are.

Like a good teacher, He doesn’t overwhelm us, but walks with us step by step.

The Holy Spirit, whom Jesus calls the “Spirit of truth,” continues to guide the Church, to form our consciences, and to lead us deeper into the mystery of God’s love.

We are still on that journey.


So how do we live this mystery?

How do we let the Trinity shape our daily lives?

Let me offer three concrete invitations:

1. Pray to the Trinity

Each time we make the Sign of the Cross, we say, “In the name of the Father, and of the Son, and of the Holy Spirit.”

This is not a routine gesture.

It is a declaration of who God is—and who we are.

We belong to this God. We live in this love.

Don’t be afraid to pray personally to each Person of the Trinity.

Thank the Father for creating and loving you.

Speak to Jesus as your Savior and friend.

Invite the Holy Spirit to guide your thoughts and decisions.

2. Seek Unity in Relationships

The Trinity is a model of perfect unity.

In a world so divided—by politics, race, ideology, and even within families—we are called to be witnesses to divine communion.

That means forgiving quickly, loving patiently, serving one another, and building bridges instead of walls.

3. Allow the Spirit to Lead You

Jesus promises that the Spirit will “guide you to all truth.”

That’s not just theological truth, but the truth of how to love your spouse, how to raise your children, how to serve the poor, how to be faithful in your vocation.

Before making a big decision—or even a small one—say, “Come, Holy Spirit.”

That simple prayer can open your heart to God’s will.


Brothers and sisters, the mystery of the Trinity is not a puzzle to be solved but a relationship to be lived.

The Father created you in love.

The Son redeemed you through love.

The Holy Spirit fills you with love and unites you to the very life of God.

This week, live in that relationship.

Pray in that love.

Share that unity with those around you.

Because the Trinity is not just who God is—it is who we are called to become.

In the name of the Father, and of the Son, and of the Holy Spirit.

Amen.
