Here's a question worth sitting with for a moment: when you think about eternal life, when do you picture it starting? If your honest answer is "after I die," you're not alone — but I want to suggest that answer is missing something essential. The eternal life that Jesus gives doesn't begin at the grave. It began the moment you were united to him. And that changes everything about how we think about what it means to learn the Christian faith.
That's where I want to begin this three-part series on catechesis — not with a curriculum or a classroom, but with a question about what's actually at stake when the church teaches the faith. Because I think we've sometimes drifted into thinking about Christian formation the same way we think about education in general, and while there's some overlap, there's also a crucial difference. Getting that difference clear is going to shape everything else we talk about in this series.
Sunday School, Bible School, and the Language We Inherit
Think about the words we use when we talk about passing on the faith. Sunday school. Vacation Bible school. Adult Bible class. We've borrowed the whole vocabulary of the educational world and planted it inside the church. And I want to be careful here — that's not necessarily wrong. There's nothing bad about those words, and there is absolutely an educational dimension to learning the Christian faith. You do need to know things. You do need to understand what the Bible says, what the creeds confess, what the sacraments mean. Knowledge matters.
But the technical term the church has used for centuries for this work of teaching the faith is catechesis. And catechesis isn't quite the same thing as education, even though it borrows some of education's tools. The difference is in the goal. And in our current cultural moment, I think that difference is more important than ever to name clearly.
When we think about education today — and I mean education broadly, the way our culture generally thinks about it — the purpose has increasingly narrowed down to this: the individual gains a body of knowledge or a skill set so that they can go out into the world and be productive. We have honest conversations with young people about going to college or trade school so they can earn enough to support themselves. There's nothing wrong with any of that. But there's been a shift. The question driving education has become "what do I get out of this for my career?" rather than "here is a body of truth that will change who I am and the way I engage with the world." The focus has tilted from formation to function.
The Problem with Graduations
Here's another piece of education culture that we've absorbed into the church without always thinking about it: the idea that learning has ending points. We call them graduations. Preschool graduation. Kindergarten graduation. Middle school graduation. High school graduation. College graduation. The whole structure of education in our culture is built around the assumption that at some point, you've mastered enough of a subject to move on. Degree in hand, you walk out the door, and you're considered sufficiently equipped for whatever you've been trained to do.
Now, the church has something that can look a little like this — confirmation. There's a moment, typically in early adolescence in Lutheran tradition, when students who have been learning the faith stand before the congregation and publicly confess what they believe. And if you've watched many confirmations, you know there can sometimes be a sense — from students, maybe from parents — that this is a graduation. That this is the finish line. That the studying is done.
But here's the thing: confirmation was never intended to be a graduation in that sense. The moment isn't saying, "You've passed the test and you're done." The moment is saying something far more significant: "I have come to know what the Christian faith is about, I confess this faith as my own, and I intend to live in this faith for the rest of my life." That's not an ending. That's a beginning — or rather, it's a public declaration of a beginning that God already made in baptism. The student isn't crossing a finish line. They're stepping into a race that doesn't end this side of eternity.
That subtle distinction matters enormously, because if we treat confirmation as a graduation, we end up with adults who figure they completed their Christian education somewhere around eighth grade and haven't thought much about it since. And the faith doesn't work that way. It never did.
Catechesis Is Formation, Not Just Information
So what is catechesis actually for, if it's not about crossing finish lines? The goal of catechesis is the formation of the whole person in the faith. Not just the accumulation of correct information — though again, that matters — but the actual shaping of a life around the truth that God has revealed. Catechesis is meant to take hold of a person. It's meant to work its way into how you think, how you love, how you forgive, how you use what you own, how you treat the people around you. It is, in the deepest sense, about learning how to be human — the kind of human being God redeemed you to be.
And catechesis, understood this way, is never really finished. It can't be, because you are never finished changing. Your relationships change. Your seasons of life change. The world around you changes. The questions you're asking at fifty are not the questions you were asking at fifteen. The griefs you carry at seventy are different from the griefs you carried at thirty. And through all of it, you need to keep returning to the words of life that Jesus gives, because those words are addressed to you — to who you actually are right now, in this moment, in this season.
"Lord, to Whom Shall We Go?"
There's a passage in John 6 that I think gets at the heart of why catechesis is different from ordinary education. Jesus has been teaching a large crowd — not just the twelve disciples, but a much wider group of followers. He's talking about being the bread of life, making the kind of claims that are genuinely offensive to the people listening. He tells them that unless they eat his flesh and drink his blood, they have no life in them. And the crowd does not receive this well. It's strange. It's hard. And the text says that many of his followers turned back and stopped walking with him.
Then Jesus turns to the twelve and asks them directly: "You don't want to leave too, do you?" And Peter speaks up. What he says is one of the most honest and beautiful confessions in the Gospels:
"Lord, to whom shall we go? You have the words of eternal life."
Peter isn't saying that everything Jesus taught was easy to understand or comfortable to hear. He's saying that there is nowhere else to go. That Jesus — and only Jesus — has the words that carry eternal life in them. That's the irreplaceable, non-negotiable center of Christian catechesis. We are not teaching a philosophy. We are not passing on a self-improvement program. We are passing on words of eternal life, because the one who speaks them is the Messiah, God in human flesh, who came into this world to redeem us by his death and resurrection.
That changes the stakes of every Sunday school lesson, every Bible class, every confirmation session, every sermon, every conversation between a parent and a child about who Jesus is. This is not just education. This is eternal life being handed from one person to another.
Eternal Life Is Not Just a Future Event
And here's where I want to push a little harder on something we tend to assume. I think most of us, when we hear "eternal life," picture something that begins after we die. Heaven is coming. Resurrection is coming. And yes — all of that is true, and it is glorious, and we hold on to that hope. But eternal life isn't only a future reality. If you are in Christ, you have eternal life right now. Today. In the middle of your ordinary Tuesday.
In Romans 6, Paul makes a staggering claim about baptism. Everyone who has been baptized into Christ has been baptized into his death. And the reason for that is so that we might walk in newness of life. There's a real sense in which, because of your union with Christ, you died two thousand years ago — connected to Jesus at the cross. And having received his death, you've also received the gift of his resurrection. You are walking around in resurrection life right now. That's what it means to be a Christian.
So the question catechesis has to keep answering isn't only "what will eternal life look like someday?" It's "how do you live eternal life in a temporal world?" How do you carry this gift — this life that goes beyond the grave — into the grocery store, into the workplace, into your marriage, into your grief, into your failures, into your ordinary days? That's not a small question. That might be the central question of the Christian life. And it's what catechesis is trying to address, week after week, year after year.
The Shape of the Life We're Learning to Live
When Lutherans think about catechesis, we think about the catechism — Luther's Small Catechism and its core parts — as a kind of framework for this formation. And it's worth thinking about what that framework actually teaches us.
The Ten Commandments give us the shape of a life lived in right relationship with God and with our neighbors. Jesus himself summarized the whole law this way: love the Lord your God with all your heart, soul, strength, and mind, and love your neighbor as yourself. Those two great commandments are not abstract principles. They are the pattern of the eternal life we're learning to live right now. And one of the tasks of catechesis is helping us figure out what that love actually looks like — especially in a world that has thoroughly confused itself about what love means.
We use the word "love" to cover an enormous range of experiences. I love my wife. I love my children. I love the Lord of the Rings. I love a good ham sandwich. Those are not the same thing, thanks be to God. The morality that flows from our faith is rooted in the eternal truth God has given us, and catechesis helps us understand what genuine love — the love that reflects God's own love — actually looks like when it walks into a real situation with real people.
The Apostles' Creed gives us the story we're living inside of — the story of what God the Father, Son, and Holy Spirit has done and is doing. It retells the atonement. It declares the resurrection. It names the work of the Spirit who delivers all of that to us. And the writer of Hebrews tells us to fix our eyes on Jesus, the author and perfecter of our faith. Catechesis trains us to keep doing exactly that — to keep looking to Jesus in two inseparable ways. First, as the Lamb of God who has atoned for our sins, so that we live in faith trusting that this atonement is genuinely for us, that we are truly reconciled to God. And second, as the one who shows us what it looks like to be fully, truly human — to love God completely, to love our neighbor radically, to display courage and gentleness, mercy and truth, all at once. We're not going to do that perfectly. Our relationship with him is always and only rooted in the fact that he died and rose for us. But we want to strive toward his likeness, empowered by the Spirit who lives in us.
The means of grace — baptism, confession and absolution, and the Lord's Supper — are the places where this eternal life is delivered and renewed. We don't just believe about these things; we receive them. And catechesis teaches us to keep coming back to these gifts, because we are people who forget, people who drift, people who need to be repeatedly reminded of what God has actually done for us.
Vocations, Neighbors, and Where the Eternal Life Shows Up
I want to make sure I say this clearly: none of what I'm describing means that earthly education and earthly work don't matter. They do. The vocations we carry throughout our lives are deeply important, and they're not separate from our catechesis — they're the context in which our catechesis gets lived out.
Think about where most of us spend the majority of our waking hours. Not in a church building. Not in a Bible study. We're at work. We're at school. We're in neighborhoods, in stores, on job sites, in hospitals, in schools, in offices. And all of those places are filled with neighbors — people we're called to love for Christ's sake. Our vocations are often the very places where we have the greatest opportunity to do genuine good for other people. We can see this clearly when we think about providing for our families — the connection between work and care is obvious. But it's worth pausing to notice that the work we do often makes life better for people we'll never even meet. The teacher shapes minds. The nurse tends bodies. The contractor builds shelter. The farmer feeds people. Our ordinary work, carried out with faithfulness and love, is a form of service to our neighbors, whether we frame it that way or not.
And all of that becomes richer, more purposeful, more rooted when it's understood in light of catechesis — in light of what God is teaching us in his Word about who we are and what we're for. Because remember: catechesis deals with eternal life. And that eternal life doesn't stay locked inside the church on Sunday morning. It bleeds into Monday and Tuesday and Wednesday. It shapes the way you treat the difficult colleague. It shapes the patience you have with the person who frustrates you. It shapes the generosity you show with the resources you've been given.
You Are a Person With a Purpose
A lot of what our culture tells us about the world — especially when it comes from a purely secular educational framework — is that this is all more or less a cosmic accident. That there's no grand meaning. That we construct our own purpose as we go, and when we're gone, we're gone. Catechesis tells a completely different story. This world was created by God. He has a plan. He has a purpose. And he has a specific purpose for you, as one of his children.
That purpose, at its deepest level, is to display God's salvation. Not to broadcast your own holiness — we're not in the business of declaring ourselves better than the people around us. Quite the opposite. In 1 Timothy 1, Paul calls himself the foremost — the chief — of sinners. And he doesn't say that as a form of false humility. He says it in order to make a point: if God can save someone like me, then God can save anyone. Your life, marked by forgiveness, shaped by grace, honest about its failures and honest about its hope, is itself a testimony. The message you carry isn't "look how righteous I've become." It's "look how gracious God is — he saved me."
That's what it means to be an agent of grace in the world. You become someone who carries this hope outward, not because you've achieved some level of spiritual accomplishment, but because you've received a gift that is simply too good not to share. And catechesis keeps equipping you for that — keeps reminding you of the gift, keeps shaping you into the kind of person who can speak that hope naturally and honestly into the lives of the people around you.
Peter writes in his letters that we who belong to Christ have become, in a sense, aliens and strangers in this world. And I think in our current cultural moment, it's worth embracing that a little. The way Jesus lived — radically loving people across every social boundary, firmly committed to truth, deeply prayerful, courageous and tender at the same time — that looks genuinely strange in our world. And maybe that strangeness is exactly what people need to see. Not a Christianity that has smoothed off all its edges and made itself as comfortable as possible, but a Christianity that actually looks like Jesus.
Learning How to Live Forever, Starting Now
This is what I keep coming back to: catechesis is really about learning how to live forever — not just for the seventy or eighty or ninety years God may give us on this earth, but for the life that has already begun in us, the life that death itself cannot end. The Holy Spirit is doing the work of sanctification in us right now — making us holy, not because we've earned it, but because we've been declared holy in Christ, and because that declaration is producing real change in real people over the course of real lives. We call that process becoming like Jesus. We never complete it here. But we keep at it, because it matters, and because the Spirit is genuinely at work.
And we need to keep being reminded. That's the honest truth about why catechesis doesn't end. We forget. We drift. We get absorbed by the noise of a loud world and lose sight of what's actually real and lasting. We need to come back again and again to the words of eternal life — the words that remind us our sins are forgiven, that God has a purpose for us, that we have been united to Jesus in his death and resurrection, and that the life we're living right now is already the beginning of forever.
So here's the question I want to leave you with as we begin this series: where are you, right now, learning to live the eternal life that Christ has given you? Not where you were learning it when you were twelve, or twenty-five, or even a few years ago — but now, in this season, with the questions and the griefs and the joys you're actually carrying today? That's worth sitting with. Because the words of eternal life are still being spoken, and they're still addressed to you.
