At Town and Country Lutheran Church, we confess the faith the Christian Church has held from the beginning: that there is one God, who exists eternally as three persons β the Father, the Son, and the Holy Spirit. Not three Gods. Not one person wearing three different hats. One God in three persons, each fully and equally God, distinct from one another yet united in a single divine being.
If that sentence makes your head spin a little, you're in good company. The Trinity is not a puzzle the Church ever expected to solve; it is a mystery we have been given to confess and adore. We don't believe it because we figured it out β we believe it because God has revealed Himself to us this way in His Word.
The doctrine of the Trinity isn't a later invention or a piece of fine print. It rises directly from Scripture. There is only one God: "Hear, O Israel: The Lord our God, the Lord is one" (Deuteronomy 6:4). And yet the Father is called God, the Son is called God, and the Holy Spirit is called God β and all three appear together as distinct persons.
We see it at Jesus' baptism, where the Son stands in the water, the Spirit descends like a dove, and the Father speaks from heaven (Matthew 3:16β17). We hear it when Jesus sends His disciples to baptize "in the name of the Father and of the Son and of the Holy Spirit" (Matthew 28:19) β one name, three persons. And we receive it in the blessing the Church has spoken for two thousand years: the grace of the Lord Jesus Christ, the love of God, and the fellowship of the Holy Spirit (2 Corinthians 13:14).
The Father is the source of all things, the Creator of heaven and earth, who loves the world and sends His Son to save it.
The Son, Jesus Christ, is eternally "begotten of the Father" β not created, not made, and not a lesser being, but true God from true God, who became man for our salvation, died, and rose again.
The Holy Spirit, who proceeds from the Father and the Son, is likewise true God, who gives faith, gathers the Church, and brings us the forgiveness and life won by Christ.
Three persons, never to be confused with one another; one God, never to be divided. As the ancient creed puts it, we worship one God in Trinity and Trinity in Unity.
Every generation tries to "explain" the Trinity with a tidy illustration β water as ice, liquid, and steam; the three leaves of a shamrock; the sun, its light, and its heat. They're well-meaning, and they all quietly fall apart, usually by reinventing a heresy the early Church already named and set aside. (The water example, for instance, accidentally turns the three persons into three temporary modes of one God β an old error called modalism.) This isn't a reason for despair. It's a reminder that the living God is greater than our metaphors, and that some truths are meant to be confessed and worshiped rather than reduced to a diagram.
This is not abstract theology reserved for seminary classrooms. The Trinity is the very shape of the Gospel. Our salvation is the work of the whole Godhead: the Father plans and sends, the Son accomplishes our redemption on the cross, and the Holy Spirit delivers it to us through Word and Sacrament. To know God as Father, Son, and Holy Spirit is to know a God who is not distant or solitary, but who has eternally been love, and who draws us into that life through Jesus Christ.
When we gather for worship, baptize in the threefold name, and bless one another in the name of the Triune God, we are not reciting a riddle. We are confessing the God who made us, redeemed us, and dwells with us still. If you'd like to explore this further, we'd love to welcome you to worship and study β and Pastor Mankin is always glad to talk. Reach out at pastor.mankin@tclutheranchurch.org.
