Trinity! Today we celebrate not a problem to solve, but a mystery to enter. The Trinity reminds us that at the center of the universe is not loneliness, not power, not fear – but relationship. Father, Son, and Holy Spirit: an eternal communion of love. And maybe that is why Trinity Sunday matters so much today, because people everywhere are searching for belonging. They want more than rules or institutions. They want connection. They want purpose. They want to know that they are loved.
As children we were told never to stare directly into the sun. It is too bright. Yet Trinity Sunday almost asks us to do exactly that – to gaze into the brilliant mystery of who God is. And when we try to explain the Trinity completely, our words fail us. Because Trinity is not just a doctrine to define, it is a relationship that changes us.
When we stand on a mountain top, or watch a sunrise over the lake, or look up at the stars on a clear Adirondack night, something stirs within us. We feel small, but also somehow held. Psalm 8 captures that feeling: “O Lord, our God, how wonderful your name in all the earth.”
And then comes the question: “What is man that you are mindful of him?” Why would the Creator of the universe care about us? The answer is Jesus Christ.
“For God so loved the world that He gave His only Son.” The Father gives. The Son receives and returns that love. The Holy Spirit pours that love into our hearts. The Trinity reveals that God is not isolated – God is self-giving love. And here is the important part for us as a Church today. If God’s very nature is communion, then the Church cannot simply be an institution that people attend. The Church must become a living community where people encounter the love of God personally.
That is one of the central insights of Divine Renovation by Fr. James Mallon and a guiding force for our parish. Father Mallon says that parishes cannot survive by maintenance alone – just trying to preserve buildings, routines, and “the way we have always done things.” A parish must become missionary. It must help people move from simply knowing about Jesus to actually encountering Jesus. And is that not exactly what the Trinity teaches us? God does not remain distant. God reaches outward. The Father sends the Son. The Father and Son send the Spirit. They very life of God is mission – love moving outward to draw others in. That means our parish should reflect the Trinity: a community of welcome, joy, love, and invitation.
People should not come here and feel like outsiders. They should discover belonging here. They should experience mercy here. They should encounter Jesus here.
Sometimes we think evangelization means having all the answers. But often it begins much more simply: learning someone’s name, listening to their story, inviting them to coffee after Mass, praying for them when they are hurting. That is how the Trinity works – through relationship.
There is a story about the great St. Augustine of Hippo trying to understand the Trinity. He saw a child on the beach pouring ocean water into a little hole in the sand. Augustine said, “You cannot fit the ocean into that hole.” And the child replied, “Neither can you fit the mystery of God into your mind.”
We cannot fully explain Trinity. But we can live it. Every act of forgiveness reflects Trinity. Every act of hospitality reflects Trinity. Every ministry that reaches out instead of turning inward reflects the Trinity. And that is the challenge for us today. Not simply to admire the mystery of God but to become signs of that mystery to others.
At the end of Mass, we will make the Sign of the Cross: “In the name of the Father, and of the Son, and of the Holy Spirit.”
Those words are not just a formula. They are our identity. We are children invited into the very life of God. So today, let us stop trying to reduce God to something manageable. Instead, let us stand in awe before the mystery – and then go forth as missionary disciples, carrying the love of the Trinity into a world desperately longing to belong.
