At various moments during His three-year ministry, Jesus spoke to crowds of thousands. He miraculously fed 5,000 people. Throughout modern history, Billy Graham packed stadiums with altar calls. Today, your nearest megachurch often operates with the precision of a sports arena, multiple times a weekend. Organizations and campaigns like ‘The Send’ have gathered hundreds of thousands of young people, calling them toward a missional life. Meanwhile, Forrest Frank shares Jesus with millions through music and social media—with hundreds of thousands expected to see him live on The Jesus Generation Tour across dozens of cities.

Humans are drawn to moments. To events. To shared experiences that feel bigger than ourselves. The good news we call the Gospel has undeniably spread through large gatherings across centuries and continents. Thank God for those moments—especially when they awaken people to a life that continues long after the crowd disperses.

The word ‘evangelism’ is often imagined as someone speaking into a microphone: ignored on a street corner, or admired by tens of thousands in an arena. In common usage today, Oxford defines evangelism broadly as ‘zealous advocacy of a cause,’ which is why people speak of evangelizing everything from Bitcoin and HYROX to lululemon and veganism. But the primary definition of evangelism remains this: ‘The spreading of the Christian gospel by public preaching or personal witness.’

The word comes from the same Greek root as gospel: euangelion. To evangelize is, quite literally, to ‘gospel’—to carry and embody the good news of Jesus Christ in word and life. Biblically, that includes public proclamation. But it also includes something quieter, slower, and more demanding: persistent personal witness within everyday relationships.

Evangelism in the early Christian church

If we step back into the world of the early Christian church, a clear pattern emerges. Evangelism was largely relational, household-shaped, and network-driven.

Faith typically moved first through those closest to you—your family members, friends, neighbors—and then outward along existing relational lines. In the first-century Mediterranean world, a household was not just a nuclear family. It included extended kin, servants, and dependents.

Early Christian gatherings were not staged primarily for outsiders. Evangelism was woven into the fabric of ongoing community life. Converts were patiently taught and formed over time, folded into shared meals, and taught to live a new way of life together. Neutral and even hostile observers noticed this. Pliny the Younger describes Christians meeting regularly before dawn for worship and again later for a communal meal—most likely in private homes, not public halls.

Historical and sociological analyses suggest that most people came to faith through someone they already knew. The New Testament reflects this consistently. While public sermons appear—especially in Acts—they function as gateways into deeply relational communities devoted to teaching, fellowship, shared meals, and prayer.

Households as the mission field

The book of Acts repeatedly highlights household-level conversions. In Acts 10, Cornelius is described as:

“A devout man who feared God with all his household, gave alms generously to the people, and prayed continually to God.”
— Acts 10:2 (ESV)

When Peter arrives, the Gospel doesn’t land on Cornelius alone. The Spirit fills the household. Baptism follows. A whole social unit is transformed.

In Acts 16, the Philippian jailer hears the word of the Lord along with everyone in his house. That very night, he sets a meal for Paul and Silas, and rejoices with his entire household.

“At that hour of the night, he took them and washed their wounds; and immediately he and all his household were baptized.”
— Acts 16:33

Lydia’s story follows the same pattern. Her heart is opened to the message, she and her household are baptized, and her home becomes the meeting place for the Philippian church.

Crispus, the synagogue ruler in Corinth, came to faith ‘together with his entire household.’ Paul later mentions baptizing the household of Stephanas, calling them the first converts in Achaia and noting that they devoted themselves to serving the saints.

God’s salvation consistently takes hold of real social units—families, homes, shared lives—and turns them into outposts of the Kingdom.

Why this still matters

The missional implications are profound. The Gospel often spreads most effectively through relational connectors—people whose lives already overlap with many others. Discipleship unfolds not in isolation, but collectively. Faith is learned by watching, sharing, eating, serving, and enduring together.

The early church was a people before it was a place. Evangelism, therefore, was not merely the communication of ideas, but a shared way of life over time.

We see this pattern in Jesus Himself. He was interrupted while walking, eating, attending weddings, sitting at wells. Good news arrived in the middle of ordinary life.

Events as sparks, communities as fire

God works through many means—printing presses and podcasts, stadiums and social feeds, live streams and DMs. Large gatherings can be powerful sparks. But without communities and households to receive, embody, and disciple people afterward, the fire fades.

In the long run, the front lines of evangelism are usually not stages or screens, but tables, living rooms, car rides, workplaces, coffee shops, and shared routines.

Clement of Alexandria once wrote, “Every place and every time in which we entertain the idea of God is in reality sacred.” Worship and witness are not confined to special buildings or moments. They begin at home.

“As for me and my house, we will serve the LORD.”
— Joshua 24:15

The New Testament consistently describes the church as a people joined to Christ — not a grand structure, institution, or corporate-like organization. In the first couple of centuries since the death and resurrection of Jesus Christ, there were no dedicated church buildings, no denominations, and no religious tax benefits.

The ‘Christian church’ was the people.

This group of witnesses and early believers had decided to put all their eggs in one basket. They had decided to see Jesus as the resurrected Messiah, the Alpha and the Omega — a Savior with authority to forgive sins. These initial followers of Jesus believed that the ancient Jewish prophecies had been fulfilled and were convinced He was the ‘chosen one.’

Those who were not Jewish — the Gentile followers of Jesus — had rejected a plethora of pagan gods, rituals, and traditions. In doing so, they renounced the impulse to worship themselves and their own ambitions and desires.

The early Christians understood that choosing to belong to this group of people would be an all-in, all-the-time, leave-everything-behind kind of commitment. To those who did not believe, this was a radically risky move. Jesus had been publicly, brutally crucified — and his disciples and the next generation of followers were being proactively persecuted, ridiculed, and put to death.

Writing about Nero’s response to the Great Fire of Rome in AD 64, the Roman historian Tacitus described how Christians in the city were singled out for awful punishment:

“…Nero fastened the guilt and inflicted the most exquisite tortures on a class hated for their abominations, called ‘Chrestians’ by the populace… Mockery of every sort was added to their deaths. Covered with the skins of beasts, they were torn by dogs and perished, or were nailed to crosses, or were doomed to the flames and burnt, to serve as a nightly illumination, when daylight had expired.”

— Tacitus, Annals 15.44 (historical account of Nero’s persecution of Christians after the Great Fire of Rome)

The early Christians lived in adoration of who Jesus was, his incarnation, and what He had fulfilled at the cross. Their faith, and hope was all in Christ.

While Paul referenced location when he called believers ‘the church of God that is in Corinth,’ he treated the church as the community of saints in a city.

“To the church of God which is in Corinth, to those who have been sanctified in Christ Jesus, saints by calling, with all who in every place call on the name of our Lord Jesus Christ, their Lord and ours.”

— 1 Corinthians 1:2

He referred to the church as ‘God’s building’ made of people, with Christ as the only foundation — not bricks and stone:

“For we are God’s fellow workers; you are God’s field, God’s building.”

— 1 Corinthians 3:9

Back then, there was nothing like what we now call ‘cultural Christianity.’ With little social benefit and real risk, it would have been rare to claim the name ‘Christian’ without serious commitment.

About a century later, an anonymous Christian wrote to a pagan named Diognetus, trying to describe what made this scattered community so different:

“Any country can be their homeland, but for them their homeland, wherever it may be, is a foreign country. They live in the flesh, but they are not governed by the desires of the flesh. They pass their days upon earth, but they are citizens of heaven. Obedient to the laws, they yet live on a level that transcends the law… Christians love all men, but all men persecute them. Condemned because they are not understood, they are put to death, but raised to life again. They live in poverty, but enrich many; they are totally destitute, but possess an abundance of everything.”

— Epistle to Diognetus 5-6 (second‑century Christian apologetic text)

Choosing to follow Jesus usually meant that your Jewish and Gentile friends and family would cut their ties from you. Christian community mattered deeply.

“For just as the body is one and yet has many parts, and all the parts of the body, though they are many, are one body, so also is Christ. ¹³ For by one Spirit we were all baptized into one body, whether Jews or Greeks, whether slaves or free, and we were all made to drink of one Spirit.”

— 1 Corinthians 12:12-13

In his 1st letter to the Corinthians, the Apostle Paul uses the analogy of the human body to explain the unity and diversity of the Christian church.

This ‘Body of Christ,’ emphasizes that while there are many different members and each believer comes with his or her own gifts — together — they form a single body. This means that each part is essential, interdependent, and honored by God, promoting harmony and mutual necessity.

In his letter to the Ephesians, Paul says God put all things under Christ’s feet — making Him the head over all things to the church.

“He put all things in subjection under His feet, and made Him head over all things to the church, which is His body, the fullness of Him who fills all in all.”

— Ephesians 1:22

The Christian church was, is, and will always be a people. It’s not a place or a thing or an entity, but a people — joined as a community, and as a body, by the God who made it all.

What a privilege and joy to be part of His church! That should make us pause, reflect, and repent. It should lead us to worship.

Have you ever walked into a church during a moment of worship and suddenly started to cry? It happens. If you’ve been to a gathering where other people were worshipping God, there’s a good chance you’ve felt this — even if briefly. Other times, you may have walked into a church, felt that something was off, and just wanted to leave.

Whether it was an emotional moment, or a real encounter with the God of Abraham, Isaac, and Jacob, joining a church gathering can stir a lot in a human being. Especially if you haven’t been to one before, or if you’re attending during a tough time in your life.

Imagine, for a second, that you’re in the first, second or third Century, Anno Domini.

Can you picture what it must have been like to join a gathering of Christians back then?

There was certainly no free espresso bar. No cup holders. No giant fish tank. No murals or stained glass or annual turkey toss. Forget the announcements, the volunteer greeter, and the A/V team setting up hours before anyone else walks in.

The early historical, biblical Christian church had none such perks. They had very different cares and concerns.

“They were continually devoting themselves to the apostles’ teaching and to fellowship, to the breaking of bread and to prayer.”

— ‭‭Acts‬ ‭2‬:‭42‬ ‭NASB2020‬‬

They were a group of people who had witnessed or heard about miracles — above all, the resurrection — and radical commands from a Messiah who claimed to be not only a savior, but also God Himself:

‘Love your enemies.’

‘Take up your cross.’

‘Turn the other cheek.’

The early church were followers of Jesus first and foremost, and the decision to believe in Him and obey what He commanded was truly life‑altering.

Over the next few weeks and months we’re going to explore what the early church was like, based on the New Testament, and historical documents, including early Christian voices who described their own gatherings.

One early writer urged believers:

“On the Lord’s day… come together, break bread and give thanks, having first confessed your sins, so that your sacrifice may be pure.”

—Didache 14 (an ancient, extra-biblical text that is useful for historical context from 70-100 AD)

Another said:

“When you assemble frequently in the same place, the powers of Satan are destroyed… by the unity of your faith.”

— Ignatius of Antioch, Letter to the Ephesians 13 (paraphrase of another ancient, extra-biblical text from 100-110 AD)

We’ll be reminded that the church was a people, not a place.

Evangelism was relational, not event-driven.

Gatherings were participatory meals that cared for the poor and the weak, rather than performances aimed at consumers.

Faith was costly; not comfortable.

Ultimately, the point was knowing, following and praising the name of Jesus — nothing and no one else.

Ps. Merry Christmas. Jesus is the only reason for the season.
