HOLY TRINITY, ONE GOD
Happy Holy Trinity Sunday. How was your experience this Eastertide? Did you develop a deeper connection with the Risen Lord Jesus? Today’s Solemnity invites us to sing our praises to God who raises us up & draws us to share in the very life of the Trinity. Today, we contemplate the central mystery of the Christian faith: a single God in three distinct Persons. For many, this sounds like a complex mathematical riddle or a dense theological puzzle – a problem to be solved. But, in essence, that’s missing the point. The Trinity, instead, is a mystery to be lived with faith & love. Thus, the liturgical readings for Year A shift our perspective entirely. They reveal that the Trinity is not an abstract concept to be solved, but a living, dynamic relationship of love to be experienced. From the rugged heights of Mount Sinai to a quiet nighttime conversation in Jerusalem, the scriptures illustrate how God continually unfolds this relational identity to humanity.
A God Who Desires Company
The journey into the Trinitarian mystery begins in the book of Exodus 34: 4-6,8-9, where Moses ascends Mount Sinai carrying two new stone tablets. Instead of a distant, terrifying deity delivering rigid commands from a cold cloud, God reveals a profoundly personal character. Passing before Moses, the Lord proclaims His own name and defines His essence:
"The LORD, the LORD, a merciful and gracious God, slow to anger and rich in kindness and fidelity."
This remarkable self-revelation is unexpected given the historical context. The Israelites had just betrayed God by worshiping the golden calf, proving themselves to be, as Moses admits, a "stiff-necked people." Yet, faced with human frailty, God could have rightly responded with destructive wrath; instead, God chose to reveal to His chosen people a declaration of His abundant, merciful love.
Captivated by this grace, Moses falls prostrate and makes a daring plea: "Do come along in our company." This request gets to the very heart of the Trinity. God is not an isolated ruler watching from afar; God is an inherently communal being who desires to walk alongside us, choosing to possess us as an inheritance despite our brokenness & flaws.
Let’s go back to Easter & the account in Luke 24:13-35 of Jesus on the Road to Emmaus. The 2 disciples were disheartened, gave up & walked away. But Jesus didn’t give up on them & walked alongside them. He reached out to them with so great a love that they pleaded “Stay with us, Lord!” (cf Luke 24:29), in the same way as Moses cried out to God.
The Communal Blueprint for Believers
Centuries later, Saint Paul concludes his 2nd letter to the Corinthians (Chapter 13 Verses 11-13) by showing us what happens when this relational God dwells among His people. Paul provides a practical roadmap for parish community life, urging believers to mend their ways, encourage one another, agree with one another, and live in peace.
This is not simple moral advice; it is a direct reflection of the Trinity. Because we are made in the image of a communal God, our spiritual health is directly tied to how we handle community. We cannot live in isolation. Paul seals this vision with a liturgical blessing of the Introductory Rite of ever Mass today:
"The grace of the Lord Jesus Christ and the love of God and the fellowship of the Holy Spirit be with all of you."
Here, the distinct roles of the Triune God are beautifully woven into our daily existence. We experience the Father through His foundational love, the Son through His transforming grace, & the Holy Spirit through a unifying fellowship. This blessing reminds us that in the Trinity, we, the Christian community breathes, acts, and finds its purpose.
Love as the Driving Force
The theological crescendo arrives in the Gospel of John 3:16-18 during Jesus' conversation with Nicodemus. In the most famous verse in scripture, the ultimate motivation for the Trinitarian mission is laid bare:
"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."
The Trinity is not a static dogma; it is a dynamic outpouring of love. Out of an abundance of love, the Father sends the Son into the world. Crucially, Christ reminds us that this mission was never about condemnation, but rescue. The Trinity functions as a divine safety net, reaching into our broken reality to lift us into eternal communion.
To believe in the Son is to step into this flow of divine love, a space where condemnation holds no power. The only judgment that exists is our self-inflicted isolation of choosing to step away from God’s love.
Living the Mystery
Ultimately, the readings for Year A show us that the Trinity is a model for how we are called to live. We worship a God who is, within Himself, a perfect relationship—a giving Father, a receiving Son, and the overflowing Love between them that is the Holy Spirit.
When we make the Sign of the Cross, we are not just marking ourselves with a symbol; we are stepping into that relationship. We are reminded that we are loved by the Father, saved by the Son, and bound together by the Holy Spirit. The mystery of the Trinity is an invitation to stop trying to figure God out, and instead allow ourselves to be swept up into His company.
