The Healing Gospel: Seeing the Unseen with Saint Luke 

Reverend Claire reflects on Luke the Evangelist and Anti‑Slavery Sunday, reflecting on Luke's healing witness and the Church’s call to confront modern slavery. Drawing on Isaiah’s vision of restoration, Jesus’ sending of the seventy‑two, and Luke’s faithful companionship with Paul, it challenges Christians to see the unseen, stand with the exploited, and carry the liberating medicine of the gospel into places of hidden suffering.

Today, our lectionary invites us to celebrate Saint Luke—the beloved physician, the faithful companion of Paul, and the evangelist who gave us both the Gospel of Luke and the Book of Acts.

Luke’s gospel has a distinct voice. It is the gospel of compassionate healing, of restoring dignity to those pushed to the margins, and of proclaiming good news to the poor and captive.

Our Collect for today, we ask that God would give His Church "the same love and power to heal" through the "wholesome medicine of the gospel".

It is particularly poignant that this year, Saint Luke’s Day coincides with Anti-Slavery Sunday.

Today, across churches in the UK, we pause to remember the millions of our brothers and sisters caught in the shadows of modern slavery—people trapped in labour exploitation, county lines drug networks, domestic servitude, and human trafficking.

At first glance of our readings, sending out seventy workers into the field or writing from a cold Roman prison cell might feel far removed from the hidden plight of human trafficking in our towns and cities today. Yet, when we read our scriptures through the eyes of Luke—the physician who noticed pain that others ignored—we discover a powerful call to see, heal, and stand firm alongside the vulnerable.

Our first reading from Isaiah sets the vision of God’s redeeming work. The prophet cries out:
"Strengthen the weak hands, and make firm the feeble knees. Say to those who are of a fearful heart, 'Be strong, do not fear! Here is your God... Then the eyes of the blind shall be opened, and the ears of the deaf unstopped; then the lame shall leap like a deer, and the tongue of the speechless sing for joy.'" (Isaiah 35:3–6)

Isaiah envisions a God who intervenes where human power fails—who brings streams into the desert and restores wholeness to broken bodies.

For victims of modern slavery, the world often feels like a desert. Exploited by criminal networks and rendered voiceless, their plight is hidden in plain sight—at hand car washes, nail bars, construction sites, and agricultural fields right in our neighbourhoods. Like the "speechless" in Isaiah, their cries are muted by fear and isolation.

To celebrate Saint Luke’s day in light of Isaiah’s vision means committing ourselves to being God’s hands and eyes.

As the Church of England’s Clewer Initiative reminds us, our first act of ministry is to say: "We see you."

We pray for eyes that are unstopped so that we can spot the signs of exploitation, notice the unseen, and help strengthen the weak hands around us.

Where do we get our cars washed? Where do we buy our clothes? What might we not be seeing or indeed closing our eyes to?
In our Gospel reading, Jesus sends out seventy-two disciples ahead of him in pairs. He gives this instruction…

"Go on your way. See, I am sending you out like lambs into the midst of wolves... Whatever house you enter, first say, 'Peace to this house!'... cure the sick who are there, and say to them, 'The kingdom of God has come near to you.'" (Luke 10:3,5,9)

Notice what Jesus asks his disciples to bring into the world - peace, healing, and presence.

He does not send them out in worldly power or wealth—they carry no purse, no bag, no sandals. They are sent out in vulnerability to offer wholeness to communities.

Also notice Jesus' warning … there are wolves.

In our world today, those wolves take the form of human traffickers and criminal gangs who target the desperate, the homeless, and young people, entrapping them in modern slavery for financial gain.

Over 40 million people worldwide—and thousands within our own borders—are exploited because of human greed and our own societal demand for cheap goods and services.

When Jesus sends us out as his Church, he calls us to carry the "wholesome medicine of the gospel" into those very places of darkness.

We are sent to bring peace, to demand fair treatment for workers—as Jesus himself noted, "the labourer deserves to be paid" (Luke 10:7)—and to proclaim that God’s reign of justice and restoration has drawn near.

Maybe this is something we’ve never considered before. But maybe worth considering.

Finally to help us in our ponderings this morning we turn to Paul’s poignant second letter to Timothy.

Paul is at the end of his life, imprisoned, abandoned by many who preferred the comforts of the present world. In verse 11, Paul writes five simple words that speak volumes - "Only Luke is with me." (2 Timothy 4:11)

When others fled out of fear or self-interest, Luke stayed. As a physician and a friend, Luke chose to stand alongside someone who was bound, isolated, and forgotten by society.

This brief mention reveals the true heart of Saint Luke’s evangelism. It wasn't just words on parchment; it was faithful, steadfast companionship with those in chains.

Today, Christ asks us: Who will stay with those who are bound? Who will stand alongside the victims of exploitation?

To follow the example of Luke is to refuse to look away. It means choosing not to be indifferent to how our cheap clothes or cheap services are produced. It means supporting anti-slavery initiatives, learning to spot the signs of modern trafficking, praying persistently for victims, and supporting organisations working on the frontline.

The gospel of Luke is a gospel of liberation and wholeness.

As we leave this service today, let us carry the prayer of today's Collect in our hearts - that God would grant His Church the same love and power to heal.

May we have the eyes of Isaiah to see the unseen and open our hearts to those who are fearful.
May we have the mission of the Seventy to bring peace, demand justice for the worker, and share the good news.
And may we have the faithfulness of Luke—to stand alongside the broken, the captive, and the forgotten.

Let us go out into the world as instruments of Christ's peace, working together until all our communities are free from slavery and filled with God's healing love.

In the name of Jesus Christ, our Healer and Redeemer. Amen
