This Sunday is my favorite Sunday of the year, save for Easter Sunday. It’s Trinity Sunday, the Sunday we celebrate what makes us Christian—that we worship One God, in Three Persons.
The Trinity can make people uncomfortable because it is not easy to understand. If you go to the Church of the Latter-Day Saints’ website, you’ll find some people who say, “I’m glad that I’m a Mormon because I don’t have to believe the doctrine of the One-in-Three.” But that’s a loss, I think, because of what Irenaeus said, which tells us more about the Trinity that many of the long books of theologians: because of his measureless love, he became what we are in order that we may become what he is. God is love, Scripture says, but love needs something to love.
Irenaeus was fighting with the Gnostics, who tended to deny the goodness of the material creation. But Irenaeus asked the question Christians always need to ask: who is Jesus? Why did he die? What did that accomplish? What does it mean for Jesus to be the Son of God who gives the Spirit? What does it mean that God pours out his love?
This means that God, like great music, is more wonderful and more interesting the more we pay attention to him. The Trinity is a union of love, and it is a union that moves through our lives and sweeps us into its life. That’s the point of Jesus—that the God outside of time becomes part of time and lifts this universe into God’s own timeless life. The Trinity is God’s outpouring of love. Or, as Jesus says in Sunday’s Gospel: “All that the Father has is mine. For this reason I said that the [Spirit] will take what is mine and declare it to you.” —John 16:15.
Come to hear what Jesus has to say. Come and join the dance of Trinity.
