The saints represent a distinctly theological way of knowing truth through their lives. The only methodology appropriate for them is a Christological one. Saints know by following the method of the one who is "the way, the truth, and the life" (John 14:6).
~ Moser, Love Itself is Understanding
What if the category of "saint" is actually the most precise word we have for what Jesus meant by "disciple"?
The question deserves more than a quick answer, because the word "saint" carries freight that most of us — particularly those of us shaped by Protestant instincts — have quietly set down. We associate it with stained glass and feast days, with a specialized religious vocabulary reserved for the canonized dead. And in setting it down, we may have set down something irreplaceable: the conviction that Christian truth is a life to be entered, a road to be walked, a Person to be followed all the way to the end. Balthasar designates saints as "theological persons" precisely because they translate theology into authentic, lived experience. The saint is the person in whom belief has become biography.
Matthew Moser's remarkable study of Hans Urs von Balthasar, Love Itself Is Understanding, gives us the theological architecture for this recovery. Balthasar's account of sainthood turns out to be, at its core, an account of discipleship — and the convergence of those two categories opens something that the Western church urgently needs to see again.
Knowing Christ by Walking His Way
The authentic disciple knows truth the way a traveler knows a road — by walking it.
This is not simply a pious metaphor. It follows directly from who Jesus is. When Jesus declares himself "the way, and the truth, and the life" (John 14:6), he is naming a mode of knowing that is inseparable from a mode of following. Truth, in this account, is a Person to be pursued. And the only way to know a Person is to walk with him — to let the road itself become the teacher, to let the rhythm of his feet become the rhythm of your own.
The earliest disciples understood this in their bodies before they understood it in their minds. They lived under Jesus' word, ate his food, absorbed his rhythms, and found their imaginations reshaped from the inside out. Formation was inseparable from following. The road was the classroom, and Jesus was simultaneously the teacher, the curriculum, and the destination. The Forgotten Ways puts it plainly: we don't think our way into a new way of acting — we act our way into a new way of thinking. The road produces the knowledge it promises, and the knowledge is only available on the road.
What this produces, in Moser's reading of Balthasar, is what Balthasar calls "the harmony of contemplation and action" — a life in which thought and practice are no longer two separate operations but a single, integrated movement. The saint is the person in whom that harmony has taken hold. Theology has ceased to be a subject and become a way of being. The road and the traveler have grown into each other.
A Living Form of Theological Existence
Doctrine does not reach its fullness in a text. It reaches its fullness in a life.
Balthasar describes the saints as a Gestalt — a particular, irreducible form of truth. Each saint's life makes Christian doctrine graspable and followable in ways that no systematic theology can achieve on its own. Moser reaches for a beautiful image here: the saints "enlarge the cathedral" of the church's truth, each one adding a fresh room, a fresh window, through which the light of divine mystery pours in for the next generation to see. The Nicene fathers gave us the grammar. The saints give us the living speech. Both are necessary, and both are given by the same Spirit.
This is a generous and demanding vision. It means that every authentic disciple is, in some sense, a theological act. Their prayers, their obedience, their particular way of loving God and neighbor — all of it becomes building material for a truth too vast for any single creed to hold. The creed names the architecture; the saint inhabits it, furnishes it, makes it livable for those who come after.
I've seen this pattern in ways that have stayed with me. At South Melbourne Restoration Community, we worked for years among people the city had largely written off — the homeless, the addicted, the institutionalized. What I discovered in that community was that the people who carried the most theological weight were rarely the ones with the most theological vocabulary. They were the ones whose lives had been so thoroughly reorganized around Jesus that you could read the gospel in the way they moved through a room. Their existence was itself a form of proclamation. That is the Gestalt Balthasar is pointing to — and it is available to every follower of Jesus, in every neighborhood, in every generation.
The Spirit's Ongoing Work
The Spirit is not finished distributing the truth of Christ.
Balthasar names the Holy Spirit as the Spirit of truth precisely as the Spirit of love — and that conjunction matters enormously. When Jesus promises that the Spirit will lead his people "into all truth" (John 16:13), he is describing an ongoing, inexhaustible unfolding of the infinite depths of Christ himself — the one in whom, as Paul writes to the Colossians, "the whole fullness of deity dwells bodily" (Colossians 2:9). Because this truth is infinite, the Spirit keeps distributing fresh charisms, fresh glimpses of the center of revelation, to each generation of disciples. There is always more of Christ to be seen, and the Spirit is always finding new eyes to see it through.
What Moser calls "glimpses of the very center of revelation" are the Spirit's ongoing work of making Christ present and legible in every time and place. The institutional and the personal dimensions of the church are partners in this work. The objective truth of the Spirit takes form in the church's ordered life: its sacraments, its offices, its Scripture. The subjective truth of the Spirit takes form in the prayers of the saints, in the personal holiness that makes revelation alive within the actual texture of human history. These two currents run together. They deepen each other.
The authentic disciple stands precisely at this meeting point — the person who carries the church's public truth into the intimacy of a personal life, and in doing so, makes that truth available to others in a form they can actually follow. The saint is the point where the river of tradition and the spring of personal encounter flow into the same stream.
Love as the Highest Form of Knowing
There is an ancient formula that Moser retrieves from the tradition, and it stops you cold when you encounter it: amor ipse notitia est — love itself is understanding.
This is not sentiment. It is epistemology. The deepest form of knowing available to a human being is the form that takes shape in love — from within a relationship that has reorganized the whole self around its object. The saint knows Christ the way a spouse knows a beloved: through sustained, costly, attentive presence over time. The knowledge grows as the love deepens. The love deepens as the knowledge grows. They are a single spiral, not two separate tracks.
The early church fathers understood this in their bones. Irenaeus, Basil, Gregory of Nazianzen, Augustine — these were lovers of God whose theology grew out of prayer, whose doctrines were forged in the crucible of pastoral care and missional risk. Their theology was, as Moser puts it, the clothing of dogma — the way a life lived wholly toward God dresses the bones of doctrine in recognizable human form. They argued from the center of lived faith outward. That is why their arguments still carry weight fifteen centuries later. Their theology is still warm.
Balthasar goes further. He calls the saints the true metaphysicians — the ones whose prayer performs the truth of Being itself and makes it known to others. What the saint knows through love, the philosopher approaches from the outside. The saint has gone further in, to the place where intellect and love are a single act of attention directed toward the living God. This is not anti-intellectualism. It is a fuller intellectualism — the kind the Shema always envisioned: "Love the Lord your God with all your heart and with all your soul and with all your strength" (Deuteronomy 6:5). The great commandment is the form discipleship takes when it reaches its fullness. Heart, soul, strength — the whole person given over, the whole person knowing.
What does this mean for how we understand discipleship? It means discipleship is an education of the whole person — mind, soul, and will — in the kind of loving attention that opens onto genuine knowledge. Formation and knowing are the same journey taken from different angles.
Christ as the Pattern of Every Life
Everything in this account of sainthood rests on a single foundation: Christ himself is the criterion of all truth.
The saint's life is a life patterned after the one in whom, as Balthasar puts it, concept becomes agent — the one who does not merely teach the truth but is the truth in his own person. Because Christ's person unites theory and practice so completely, every life genuinely patterned after him inherits this same unity. The form of Christ is the template; the saint is the living impression of that template in a particular human history. Each impression is unique. Each one is recognizably Christ.
This is why Bonhoeffer could write, with such devastating clarity, that "Christianity without discipleship is always Christianity without Christ." A doctrinal system held at arm's length — a general religious knowledge that produces no conformity to Jesus — has lost the very thing that makes it Christian. The authentic disciple is the one who has taken the map seriously enough to actually set out, to put feet on the road, to let the journey do what journeys do.
And here is where the category of sainthood becomes most urgent for us. We live in a moment when the Western church is extraordinarily well-resourced theologically. More books, more podcasts, more conferences, more content than any generation of Christians in history. The theological grammar is everywhere available. What is rarer — and what the world is actually waiting for — is the living speech. The life that makes the grammar audible. The saint who closes the gap between what we know and what we are.
The World Needs a Life It Can Read
The saints stand as living proof that this fusion is possible — and that it is the normal calling of every follower of Jesus.
Every generation of the church has needed people in whom the gospel is inhabited — people whose lives constitute a form of truth that the world can actually read. The early church grew because it produced people who loved differently, died differently, and cared for the forgotten in ways that made no sense apart from the resurrection. The message traveled in the bodies of its messengers. The movement was the people, and the people were the message.
That is still how it works. The world around us is waiting to encounter a life so given over to Christ that the argument becomes unnecessary — a life that is itself the evidence, the cathedral made flesh, the theology made walkable.
To call the saint the authentic disciple is to recover something that has been with us from the beginning, coded into the very DNA of the movement Jesus started. Disciple-making is the church's nature. And when we recover it — when we treat theology as a way of walking and love as the highest form of knowing — we find ourselves in the company of every saint who has gone before us, enlarging the cathedral, one life at a time, until the whole earth is full of his glory.
