A few years ago, someone asked me a question that many priests have heard before: “Father, can you explain the Trinity?” I smiled and asked, “How much time do you have?” Because whenever we talk about the Trinity, people often expect a math lesson. One God. Three Persons. Not three gods. Not one Person wearing three masks. Three Persons in one God. And in no time people begin to doze off.
And that is unfortunate because the Trinity is not meant to be a headache. The Trinity is not a puzzle. The Trinity is good news. In fact, if you remember only one thing from today’s homily, remember this: The doctrine of the Trinity is God’s way of telling you that love existed before the universe did. In other words, before there was a sun, before there was a moon, before there were stars, before there were oceans, before there was a single human being, there was love. Because before creation, the Father loved the Son. The Son loved the Father. And the Holy Spirit is the bond of that eternal love. God did not become loving when he created us. God is love. Love is not something God does. Love is who God is.
Many people imagine God as a lonely old ruler sitting somewhere above the clouds, watching the world and waiting for people to make mistakes so he can punish them. But that is not the God revealed in Scripture. In today’s first reading, when God reveals himself to Moses, he does not begin with power. He does not begin with judgment. He introduces himself as “a merciful and gracious God, slow to anger and rich in kindness and fidelity.” That is who God says he is.
And then in the Gospel passage, Jesus gives us one of the most famous verses in the entire Bible: “For God so loved the world that he gave his only Son.” Jesus does not say God tolerated the world. He does not say God put up with the world. He does not say God was disappointed with the world. He says, “God so loved the world.” Not because the world was perfect. Not because humanity earned it. Not because we deserved it. But because of who he is. God is love. God loved first.
Sometimes people ask, “Why did God create us?” The answer is not because God needed servants. God did not create us because He was lonely. The Trinity was already complete. The Father, Son, and Holy Spirit lacked nothing. God created us because love, by its nature, wants to be shared. A healthy family knows this. When a husband and wife welcome a child into their home, they do not do so because their love was insufficient. They do so because love naturally expands. Love overflows. Love gives. Love shares itself. Creation itself is the overflow of God’s love. And salvation is the proof of that love. That is why the Gospel says that the Father sends the Son. Everything God does is directed toward bringing us into his life.
The goal of Christianity is not merely to get people into heaven someday. The goal is to bring people into the life of the Trinity even now. This is why every prayer begins: “In the name of the Father, and of the Son, and of the Holy Spirit.” This is why every baptism happens “In the name of the Father, and of the Son, and of the Holy Spirit.” This is why at the end of Mass we are blessed “In the name of the Father, and of the Son, and of the Holy Spirit.”
The Trinity is not a chapter in a theology textbook. The Trinity is the atmosphere in which Christians live. We were created by the Father. Redeemed by the Son. Sanctified by the Holy Spirit. And every day of our lives is meant to draw us deeper into that divine communion. That is why Saint Paul ends today’s second reading with words we hear so often that we may overlook their beauty: “The grace of the Lord Jesus Christ and the love of God and the communion of the Holy Spirit be with all of you.” Take a moment and reflect on the three gifts from the Trinity: Grace. Love. Communion. Not fear. Not shame. Not distance. Grace. Love. Communion. That is the life of the Trinity. And that is the life God wants for us.
My dearly beloved in Christ, perhaps the greatest tragedy is that many people know about God but have never truly believed that God loves them. They believe God exists. They believe God is powerful. They believe God is watching. But they are not convinced that God delights in them. Today’s feast tells us otherwise. The Father did not send the Son to condemn you. The Son did not die to shame you. The Holy Spirit was not given to abandon you. The entire life of the Trinity is moving toward you in love.
So when you make the Sign of the Cross today, do not do it mechanically. Remember what you are saying. You are placing yourself in the name of the Father who created you, the Son who died for you, and the Holy Spirit who lives within you. You are placing yourself inside an eternal exchange of love that existed before the world began and will exist long after the world has passed away. And here is the truth we must never forget: The Trinity is not simply something Christians believe. The Trinity is the home into which Christians are invited.
