Baptized into the Trinity

Sermon — Trinity Sunday, June 4, 2023

The Rev. Greg Johnston

Lectionary Readings

Now, you might think that scheduling a baptism on Trinity Sunday is just a clever way of getting out of preaching a sermon on the Holy Trinity. You might even appreciate the effort. After all, Trinity Sunday, this Sunday after Pentecost every year, has something of a reputation for rough sermons. Preachers tend to either go very theological, regurgitating large chunks of seminary classes into fifteen-minute discourses featuring words like “perichoresis” and “hypostatic union”; or they tend to veer a bit in the other direction. I once heard a sermon on Trinity Sunday, the day that happened to mark the end of the church “program year,” which started by calling the Trinity a fourth-century political compromise, then proceeded to just list all the wonderful things that the church had done that year, before concluding, “And that’s

So, A baptism might seem like a fitting escape from this dilemma. There’s no better antidote to a dry exposition of fifth-century theological philosophical and theological debates, after all, than a really cute baby. But I’m sorry to tell you that the Trinity and baptism go hand in hand.

Our readings this morning, you may be surprised to hear, were not chosen because we had a baptism. They’re simply the readings for Trinity Sunday. These aren’t baptism readings and yet we begin, just as the Thanksgiving over the Water later in this service will begin, with the image of the Spirit of God hovering over the waters of the deep, as God prepares to bless the new life that is coming forth. (Gen. 1:2) These aren’t baptism readings and yet we end with Jesus’ final words to his disciples, taken from the Gospel according to Matthew, “Go therefore and make disciples of all nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit.” (Matthew 28:16)

The Trinity, an abstract, technical, dry topic, seems quite different from Baptism, a hands-on, messy, and rather wet practice, and the two can’t be separated from each other. And the reason for this, it turns out, is that the Trinity is not actually an abstract theological claim. And the Trinity is not really a fourth-century political compromise. The Trinity is a person—or, three persons, anyway, I guess that’s the point. The Trinity isn’t an idea about God, the Trinity is God: Father, Son, and Holy Spirit; and this tells us everything about the meaning of Baptism.

To say that God is Trinity is to say that God has always existed and will always exist as a relationship, a community of love within God’s own self. And to say that we are baptized “in the name of the Trinity” is to say that we are invited into that relationship; that each one of us is drawn into that community of love. One of my favorite little New Testament facts is that the preposition Matthew uses here means “in” in the sense of “into,” not in the sense of “by.” In other words, we baptize people “into the name of the Father and of the Son and of the Holy Spirit,” not “by the power invested in the name.” All of us who have been baptized have been baptized into a new identity, a new name, a new family. Baptism adopts us into the family of God, and incorporates us into a community of love.

In one sense, baptism incorporates us into the community of the Church. When a child is baptized she is no longer the sole responsibility of her parents or grandparents; they are no longer her only family. She becomes our sister in Christ, a member of all our family, under God. And we take that as seriously as we can. In a few minutes, everyone in this room will make a promise, on behalf of the whole Church throughout the world, to do everything in our power to support her. And, God willing, when she need us, we will. Wherever she goes, whoever she becomes, she will always have a home in the family of God.

But baptism does more than just invite us into the Church. Baptism makes us part of the Body of Christ, baptism brings us, in a sense, into the very heart of the life of God. By the power of God the Holy Spirit, every person who is baptized is made a spiritual member of the living Body of God the Son, and God the Father looks on her with the same love that has existed within God’s own being from before time, the same love that led God’s voice to boom out from heaven at Jesus’ own baptism and say, “This is my beloved child, in whom I am well pleased.” God looks at each one of you and sees a beloved child, in whom God delights and is well pleased. And wherever you go, and whoever you become, God’s love and compassion and care will follow you. And God sees you as you see a sweet and beloved little child: indescribably beautiful, unbelievably frustrating, incomprehensibly messy, and loved beyond anything that could ever be imagined.

So, to all who are baptized, welcome into the family of God. May God the Father bless you with the knowledge and love of God, and of God’s love for you. May God the Son inspire you to walk in the way of love for your neighbor. Maybe God the Holy Spirit guide you and comfort you as you grow in stature and in faith. And may you remember that God is “with you always, even to the end of the age.” (Matthew 28:20)

Amen.
