One of the most compelling descriptions of Christian identity outside the New Testament comes from an anonymous second-century letter known as The Epistle to Diognetus. Written sometime in the second century, the letter seeks to answer a simple question: Who are these followers of Jesus, and why do they live the way they do?
The author’s answer remains startlingly relevant today.
At a time when many Christians feel pressured either to withdraw from society or to seize cultural power, Diognetus offers another way—a vision remarkably aligned with the Jesus Way.
The writer concludes with this beautiful image:
“To sum it all up in one word, what the soul is in the body, that is what Christians are in the world.”
The metaphor deserves our careful attention.
Not Above the World, Not Outside the World
The soul is not separate from the body. It is not perched above the body, controlling it from a distance. Nor is it absent from the body altogether. Rather, the soul is present throughout the body, animating it, giving it life, holding it together.
The author continues:
“The soul is dispersed through all the parts of the body, and Christians are scattered through all the cities of the world.”
Notice where Christians are found.
Not in monasteries removed from ordinary life. Not gathered into enclaves isolated from their neighbors. Not occupying the centers of imperial power. Christians are scattered throughout the cities.
Among merchants and laborers.
Among families and strangers.
Among the wealthy and the poor.
Among those who govern and those who are governed.
Their vocation is not escape but presence. This is, of course, the pattern we see in Jesus himself. The Word became flesh and moved into the neighborhood.
Jesus did not save the world from a safe distance. He entered fully into the complexity, beauty, and brokenness of human life. He walked dusty roads, attended weddings, shared meals, touched lepers, welcomed children, and confronted powers that diminished human flourishing.
The Jesus Way has always been an incarnational way.
In the World, But Not Of It
The writer then adds another layer:
“The soul lives in the body, yet is not of the body; Christians live in the world, yet are not of the world.”
Too often these words have been interpreted as a call to separation.
But that is not what the author means. The soul does not reject the body. The soul does not despise the body. The soul loves the body by giving itself for the body’s flourishing.
Likewise, Christians are called neither to assimilation nor domination.
The church loses its witness when it simply mirrors the fears, desires, and ambitions of the surrounding culture. Yet it also loses its witness when it seeks to control the culture through coercion.
The Jesus Way offers another possibility.
Christians are invited to inhabit the world while being shaped by another imagination. In a society organized around competition, they practice generosity. In a culture of scarcity, they embody abundance. In systems fueled by fear, they cultivate trust. In an age of enemies, they practice love. In contexts marked by exclusion, they make room for strangers. Their lives become signs of another kingdom. Not because they have withdrawn from the city, but because they have learned how to be differently present within it.
The Hidden Work of the Soul
Perhaps the most provocative line comes next:
“The invisible soul is guarded by the visible body. So Christians are known to be in the world, but their godliness remains invisible.”
The soul performs its work quietly. It rarely draws attention to itself. Its influence is profound precisely because it is not performative.
The same is true of the most transformative expressions of Christian witness. The Jesus Way has rarely advanced through spectacle.
It advances through faithfulness. Through neighbors who care for one another. Through communities that welcome outsiders. Through the daily practice of reconciliation. Through shared meals. Through forgiveness. Through generosity. Through patient presence. Through people who choose love over fear, service over status, and hope over cynicism.
These practices often go unnoticed by the powers of the age.
Yet they become the hidden architecture of human flourishing.
Like roots beneath a forest floor.
Like yeast in dough.
Like seeds beneath the soil.
Like a soul animating a body.
Christians as the Soul of the City
What might it mean for followers of Jesus to become the soul of the city?
Not the rulers of the city.
Not the owners of the city.
Not the moral police of the city.
The soul of the city.
To be dispersed throughout neighborhoods, schools, workplaces, parks, coffee shops, community organizations, and public institutions.
To participate fully in the common life of our communities.
To seek the flourishing of all and everything.
To embody an alternative social imagination grounded in mercy, justice, hospitality, and peace.
To join God in the healing of relationships—with God, neighbor, self, and creation.
This vision stands in sharp contrast to both Christian nationalism and Christian withdrawal.
One seeks dominance.
The other seeks escape.
The Jesus Way seeks faithful presence.
Like the soul in the body, Christians are called to be woven throughout the life of the world—not controlling it, not abandoning it, but animating it with the love of Christ.
Nearly two thousand years after the author of Diognetus penned these words, his vision remains both a challenge and an invitation.
The question is not whether Christians will influence the city.
The question is how.
Will we seek power over?
Or will we become a life-giving presence within?
The anonymous author offers a compelling answer.
What the soul is in the body, Christians are called to be in the world.
Quietly.
Faithfully.
Lovingly.
For the sake of the flourishing of all.
Peace, dwight
