Trinity Sunday - The God Who Is Communion

Today the Church asks us to stand before the mystery of the Holy Trinity.

One God. Father, Son, and Holy Spirit.

Not three gods. Not three masks. Not a holy math problem. Not some theological puzzle we are meant to solve before we are allowed to worship.

The Trinity is not a riddle. The Trinity is the life of God opened to us.

That matters because many of us were taught doctrine as if it were mostly about getting the right answer. Learn the right words. Repeat the right formula. Avoid the wrong explanation. Keep yourself safely inside the lines. There is a place for careful words. The Church had to fight hard for them. The creeds did not fall out of the sky. They were prayed, argued, suffered over, and defended because the Church knew that the truth about God shapes the truth about us.

But doctrine is not meant to sit cold on a shelf. Doctrine is meant to become doxology. What we confess with our lips, we learn to love at the altar. What we say about God shapes how we treat one another.

So when we say God is Trinity, we are saying God is not isolated power. God is not cold authority. God is not a distant monarch ruling creation from a safe distance. God is communion. God is relationship. God is love before love ever had a created thing to love.

Before there was a world, there was communion. Before there was light, there was love. Before there was breath in our lungs, there was the eternal life of the Father, the Son, and the Holy Spirit.

That means love is not something God started doing after creation. Love is who God is.

This is where we begin. Not with an explanation that masters God, but with a confession that humbles us. God is holy. God is love. God is communion. And by grace, we are invited into that life.

Isaiah begins in a hard place. He says, “In the year that King Uzziah died, I saw the Lord.”

That small historical note carries weight. King Uzziah’s death was not just a date on a calendar. It marked a time of uncertainty. The king was gone. The old stability was shaken. The future was not clear. People did not know what would come next.

That is where Isaiah sees the Lord.

Not in a settled season. Not when everything was calm. Not when the nation had figured itself out. Isaiah sees the Lord in a time of grief and public uncertainty.

That feels familiar.

We know what it is to live in times when the ground feels unsteady. We know what it is to look around and wonder what kind of world is being handed to our children. We know what it is to hear loud voices, angry voices, fearful voices, religious voices that do not sound much like Jesus. We know what it is to watch institutions wobble. We know what it is to wonder whether the Church will be brave enough to be the Church.

And in that kind of moment, Isaiah sees the Lord.

He sees the Lord seated on a throne, high and lifted up. The robe of the Lord fills the temple. Seraphim cry out to one another, “Holy, holy, holy is the Lord Almighty. His glory fills the whole earth.” The foundations shake. The house fills with smoke.

This is not sentimental religion. This is not soft background music for a spiritual mood. This is holiness. This is the kind of encounter that strips away pretense.

Isaiah’s first response is not confidence. He does not say, “Finally, I have the vision I deserve.” He does not say, “I am ready to lead.” He says, “Woe is me. I am lost. I am a man of unclean lips, and I live among a people of unclean lips.”

In the presence of God, Isaiah tells the truth.

That is one of the first gifts of real worship. It tells the truth. Not to crush us. Not to humiliate us. Not to make us afraid of God. It tells the truth so that mercy can reach the place we usually hide.

Isaiah names his unclean lips. His speech. His words. The way his mouth has been shaped by the world around him. That is not hard to understand. We live in a time of unclean lips too. Not because people use the wrong religious vocabulary, but because words are often used to wound, divide, manipulate, and dehumanize. We have watched speech become a weapon. We have watched lies become strategy. We have watched cruelty become entertainment. We have watched people speak about immigrants, LGBTQIA+ people, the poor, the disabled, women, people of color, and the wounded as if they were problems to manage instead of icons of God to reverence.

Isaiah stands in the temple and says, “My lips are unclean, and I live among a people whose lips are unclean.”

That confession belongs to all of us.

But God does not leave Isaiah in shame. A seraph takes a coal from the altar and touches his mouth. The place of confession becomes the place of cleansing. The place of fear becomes the place of calling.

Then Isaiah hears the voice of the Lord saying, “Whom shall I send? Who will go for us?”

And Isaiah says, “Here I am. Send me.”

Notice the order. Isaiah is not sent because he is pure enough to be useful. He is sent because God is merciful. He is not called after proving his strength. He is called after being touched by grace.

That is the pattern of the Church’s worship. We come into the holy place. We hear the Word. We see ourselves truthfully. We confess. We are met by mercy. We receive from the altar. Then we are sent.

The liturgy is not an escape from the world. The liturgy is where God heals us enough to return to the world differently.

That is why this matters for Trinity Sunday. The holy God does not remain far away. The holy God calls. The holy God cleanses. The holy God sends. The God who is communion draws Isaiah into communion with the divine purpose. Worship becomes mission.

Psalm 29 keeps us in that same sense of awe. “The voice of the Lord is heard on the seas. The glorious God thunders.” The voice of the Lord breaks the cedars. The voice of the Lord shakes the wilderness. The voice of the Lord makes the people cry, “Glory.”

This is not a small God. This is not a private God. This is not a God who belongs to one tribe, one party, one nation, one denomination, or one style of worship. The voice of the Lord is over the waters.

That image takes us back to creation, where the Spirit of God moves over the face of the deep and God speaks light into being. It also takes us to the Jordan, where the Son stands in the water, the Spirit descends, and the voice of the Father names him beloved.

Water. Voice. Spirit. Belovedness.

The Trinity is not revealed to satisfy curiosity. The Trinity is revealed in the saving work of God.

The Father speaks. The Son stands with us in the waters of our humanity. The Spirit descends. Heaven opens. Love moves toward creation.

That is the God we worship.

And that matters because many voices are speaking over the waters now. Voices of fear. Voices of control. Voices telling us to protect only our own. Voices telling us mercy is weakness. Voices telling us some people are disposable. Voices telling us that the Church should be a fortress instead of a table. Voices telling wounded people to stay quiet so the comfortable do not have to be disturbed.

But Psalm 29 tells us there is a deeper voice.

The voice of the Lord is stronger than the storm. It breaks what needs breaking. It shakes what needs shaking. It strips away false strength. And then the psalm ends with a promise. “The Lord gives strength to his people and blesses them with peace.”

Strength and peace belong together.

Strength without peace becomes domination. Peace without strength becomes avoidance. God gives both. Strength to stand. Peace to love. Strength to tell the truth. Peace to remain human while telling it. Strength to resist evil. Peace to refuse becoming evil in the process.

That is not abstract theology. That is a way to live.

Then Paul brings this mystery down into the life of a wounded church. The Corinthians were not an easy parish. They had division, pride, spiritual competition, moral confusion, and arguments over status. They had gifts, but they did not always have maturity. They knew how to speak in tongues, but they did not always know how to love each other.

So Paul ends his letter with this blessing: “The grace of the Lord Jesus Christ, the love of God, and the fellowship of the Holy Spirit be with you all.”

Grace. Love. Fellowship.

This is not decorative language. It is the medicine the Church needs.

The grace of Jesus Christ meets us where we fail. It is the grace that took on flesh, sat at table with sinners, touched the unclean, forgave enemies, and rose from the dead with wounds still visible.

The love of God creates, sustains, and refuses to abandon the world. It is the love that runs toward the prodigal. The love that numbers the hairs of our head. The love that sees the sparrow fall. The love that calls creation good and keeps working to make all things new.

The fellowship of the Holy Spirit is not shallow friendliness. It is communion. Shared life. The Spirit gathers people who would not have chosen each other and makes them one Body. The Spirit helps us pray when our words fail. The Spirit binds the wounded together without pretending they were never wounded.

Paul is not offering the Corinthians a religious slogan. He is telling them that the life of the Trinity is the life the Church must learn to practice.

That is where Trinity Sunday becomes uncomfortable in the right way.

We cannot worship the Trinity and practice contempt. We cannot confess one God in three Persons and then build communities where only some people matter. We cannot say “Holy, holy, holy” and then treat the image of God in our neighbor as negotiable.

If God is communion, then the Church must learn communion. If God is love, then the Church must embody love. If God is relationship, then our relationships are not secondary to our faith. They are one of the places our faith is tested.

And we have to be honest. The Church has not always looked like communion. Sometimes the Church has looked like control. Sometimes it has looked like fear dressed in vestments. Sometimes it has protected systems more quickly than people. Sometimes it has guarded traditions in ways that forgot the living God those traditions were meant to serve.

Some of us know that wound personally. Some of us carry religious wounds in our bodies. Some of us have watched people we love pushed away from the table in the name of a God who is supposed to be love. Some of us were told there was no room for our questions, our grief, our bodies, our marriages, our children, our callings, or our full humanity.

That is why it matters that God is Trinity.

Not because the doctrine gives us a clever answer, but because it reveals that the deepest truth of God is not exclusion. It is communion.

The Father creates and calls us beloved. The Son enters the fullness of our human condition and restores what has been broken. The Spirit breathes in us and makes communion possible again.

This is the God who saves us.

In John’s Gospel, Jesus tells the disciples something tender and honest. He says, “I have much more to tell you, but now it would be too much for you to bear. When, however, the Spirit comes, who reveals the truth about God, he will lead you into all the truth.”

That line has always stayed with me.

“I have much more to tell you, but now it would be too much for you to bear.”

Jesus knows our limits. He knows we do not receive all truth at once. He knows revelation is not always poured into us in one overwhelming moment. Sometimes the Spirit has to lead us slowly because we are not ready for the whole road.

That is not failure. That is discipleship.

The Spirit leads us into truth. Not away from Christ. Deeper into Christ. The Spirit does not give the Church a different Gospel. The Spirit takes what belongs to Christ and makes it known in the life of the Church.

This means the Church must remain humble.

We are still being led.

The early Church had to be led into truth. It had to learn that Gentiles belonged without first becoming Jews. That did not happen because everyone woke up one morning already settled. It took prayer, argument, testimony, Scripture, council, and the visible work of the Spirit among people the Church did not expect.

That same Spirit still leads.

The Spirit teaches the Church to see where we made the table smaller than Jesus made it. The Spirit teaches us to hear voices we dismissed. The Spirit teaches us that holiness is not separation from the wounded, but union with Christ among them. The Spirit teaches us that tradition is not a locked room. It is a living river.

That does not mean anything goes. It means the living God still speaks, and the test is always Christ.

Does this lead us closer to Jesus? Does this deepen love of God and neighbor? Does this bear the fruit of the Spirit? Does this heal, restore, reconcile, and set free? Does this make the Church more faithful to the One who ate with sinners, touched the unclean, defended the shamed, and broke bread with betrayers?

The Spirit leads us into all truth, but truth is not merely information. Truth has a face. Truth is Christ.

So when we bring these readings together, Isaiah shows us holiness. Psalm 29 shows us glory. Paul shows us communion. John shows us the Spirit leading the Church forward.

Together, they show us the Trinity.

God above us in majesty. God with us in Christ. God within us by the Spirit.

Even that language is too small, but it helps us pray. The works of God are not divided into separate departments. Where the Father works, the Son and Spirit are present. Where the Son acts, the Father and Spirit are present. Where the Spirit moves, the Father and Son are present. God is one.

The Father creates through the Word in the Spirit. The Son saves in obedience to the Father through the Spirit. The Spirit sanctifies us by uniting us to the Son, who brings us to the Father.

From the Father, through the Son, in the Holy Spirit, and back into the communion of God.

That is the shape of salvation.

That is why our worship is Trinitarian even when we do not stop to explain it. We bless in the name of the Trinity. We baptize in the name of the Trinity. We pray to the Father, through the Son, in the power of the Holy Spirit. In the Eucharist, we offer praise to the Father, we are joined to the self-giving life of the Son, and we call upon the Holy Spirit to make the gifts holy and to make us holy too.

Then we receive Communion.

Not as a private religious object. Not as a reward for the worthy. Not as a prize for having figured everything out.

We receive Communion as participation in the life of God.

The Eucharist is the table of the Trinity. The Father welcomes. The Son gives himself. The Spirit makes us one.

Then we are sent.

That is where Trinity Sunday becomes practical. If we have received the life of God, then we are called to live as people of communion.

First, we are called to reverence. Isaiah’s vision reminds us that God is holy, and we are not. That is not meant to make us afraid in a childish way. It is meant to make us honest. We need a recovery of reverence in the Church. Not stiff performance. Not religious theater. Reverence. The kind that knows our opinions are not the same thing as divine wisdom. The kind that allows God to cleanse our lips before we speak in God’s name.

A lot of harm has been done by people who spoke for God before letting God touch their mouths with fire. We need cleansed speech. Speech that blesses and does not curse. Speech that tells the truth without cruelty. Speech that names sin without forgetting mercy. Speech that protects the vulnerable instead of shaming them.

Second, we are called to communion. Paul tells the Corinthians to encourage one another, be restored, and live in peace. That does not mean we all become the same. The Trinity is not sameness. The Father is not the Son. The Son is not the Spirit. The Spirit is not the Father. And yet God is one.

Unity is not uniformity.

That matters for us as Convergent Catholics. We draw from East and West. From sacramental, evangelical, charismatic, and affirming streams. That is a gift, but it is also work. Communion does not happen by accident. It takes patience. It takes repentance. It takes listening. It takes giving up the need to win every room. It takes the courage to belong to people who do not always sound exactly like us.

If God is communion, difference does not have to become threat. In Christ, difference can become gift.

The Church should be one of the few places left where people learn how to belong without disappearing.

Third, we are called to be sent. Isaiah hears, “Whom shall I send?” and he answers, “Here I am. Send me.” The Spirit in John’s Gospel leads the disciples into truth so they can bear witness. Paul’s blessing is not meant to end in the room. Grace, love, and fellowship become a way of life.

So we are sent.

Sent to our families. Sent to our neighborhoods. Sent to the tired and forgotten. Sent to those who have given up on the Church because the Church gave up on them first. Sent to those who were told they were too queer, too broken, too divorced, too poor, too doubtful, too different, too wounded, or too much.

We are sent to say with our lives what we say at this altar.

There is room. There is mercy. There is healing. There is a God whose life is love, and that love has come near.

We are not sent because we are impressive. Isaiah was sent after admitting he was undone. The disciples were sent while still confused and grieving. The Corinthians were blessed while still learning how to live together.

We are sent because God is merciful. We are sent because the Spirit still breathes. We are sent because Christ is not finished with the world.

Beloved, the Trinity is not distant.

Every act of mercy bears the imprint of the Trinity. Every honest confession is met by the Trinity. Every table where strangers become family reflects the Trinity. Every time the Church chooses love over fear, communion over control, truth over performance, and mercy over exclusion, the life of the Trinity becomes visible.

So today, do not try to solve God.

Stand before God. Let the holiness of God tell the truth. Let the mercy of God cleanse what is wounded. Let the voice of God speak louder than the storm. Let the grace of Christ meet you at the table. Let the love of the Father name you beloved. Let the fellowship of the Spirit draw you back into communion.

And when God asks, “Whom shall I send?”

May we have enough courage, enough humility, and enough love to answer:

Here we are. Send us.
