I present this particular article not because I want to promote or defend large or small churches. I am also not seeking to promote what is typically called the "House Church" movement, realizing that churches met in homes in the New Testament as a practical matter and not from a theological/doctrinal perspective.
I primarily seek to promote a biblical New Testament understanding of the church's work. I also write because I am aware that many churches are getting smaller and smaller.
Church Size (Average Weekly Attendance) | Percentage of Churches |
1-50 attendees (within this category is a special developing category called "micro churches" with 10-40 members - they make up about 5-10% of churches in America, but the percentage is increasing). | 30-40% |
51-100 attendees | 35% |
101-250 attendees | 15% |
251-500 attendees | 8% |
501-1000 attendees | 3% |
1001-2000 attendees | 1.5% |
2000+ attendees (mega-church) | 0.5% |
The majority of American churches are small, with roughly 65–75% of churches having fewer than 100 attendees on an average Sunday.
Only 4–5% of churches have over 500 attendees, and a very small fraction (0.5%) qualify as megachurches with 2,000 or more weekly attendees.
This distribution highlights that small churches are far more common than large congregations, though larger churches accommodate a significant portion of overall church attendance due to their higher capacity.
This leads us to believe that the weight of the American church work rests squarely on the shoulders of the smaller church.
American Christianity has long shown a fascination with large churches, and many young preachers today seem to aspire to serve in similarly large settings. This perspective is understandable, as many of these leaders were trained in large ministries or colleges where the importance of 'BIG' may not have been explicitly emphasized but was often absorbed by example. For some, the desire for growth can sometimes lead to an emphasis on personal visibility or recognition. However, it’s crucial to encourage a mindset rooted in faithful service and humility rather than a drive for personal prominence. We should seek to cultivate a ministry approach that values the glory of God over lesser considerations (like the size of our church).
Young preachers in Independent Baptist churches often hear stories from the older generation about 'the good ole days,' which can shape their perspective on ministry. While these memories can provide valuable insights, relying too heavily on this nostalgic view can be limiting and counterproductive. Therefore, let’s take the time to engage with this topic thoughtfully.
One question that intrigues many Christians today is what was the first-century church really like. This consideration can guide us today on many levels. One question that could be asked is: How large were the churches of the New Testament era? While the Bible, as a general practice, doesn't provide exact attendance figures, historical records, and New Testament references give us a glimpse into what these early gatherings may have looked like. Understanding the size of early churches can shed light on the unique community dynamics of the first Christians and offer perspective on the concept of church growth.
House Churches: The Primary Gathering Space
Early Christian communities met primarily in homes, as we see in Paul's letters: "Greet also the church in their house" (Romans 16:5, 1 Corinthians 16:19, Colossians 4:15). This home-centered practice wasn't just for intimacy; it was often a practical necessity. Homes in the Roman Empire had limited space, so early churches likely accommodated only 20 to 40 people per gathering.
These small groups provided an intimate setting for worship, teaching, communal meals, and personal fellowship. Church gatherings focused on relationships, encouragement, and growing in the faith together.
Urban Centers and Larger Christian Communities
While each house church was relatively small, major urban centers like Jerusalem, Ephesus, Antioch, and Rome had growing numbers of believers. For instance, after Peter’s sermon on Pentecost, three thousand people were added to the faith (Acts 2:41). This initial large group likely dispersed into smaller home gatherings across the city, with each church overseen by local elders and leaders.
As Christianity spread, cities with more significant Christian populations seemed to have organized themselves into loose networks of house churches that collectively represented the church in that region. This structure allowed the urban church to function cohesively while maintaining a local, small-group feel in each home. This approach would lead to organizational problems later with larger churches and urban-centered churches expressing dominance and control that was never granted to them by Apostolic authority.
Persecution and the Need for Small Gatherings
Early Christians frequently faced hostility from Roman authorities, especially as Christianity grew in influence. Small, discreet gatherings were a necessity for safety, and these smaller churches were less likely to attract unwanted attention. In times of persecution, large gatherings could endanger the entire community, whereas small groups helped ensure privacy, secrecy, and security. Due to the reality of persecution, witnessing during the New Testament era was typically conducted with more discretion and caution. Early believers were not likely to engage in door-to-door witnessing as is commonly encouraged today. Their witness was likely more personal and private, integrated into the everyday routines of life.
Despite persecution, the church’s resilience in this format proved effective. As believers preached their faith and converts multiplied, new churches were established across cities and rural areas alike.
The Total Christian Population in the First Century
While exact figures are difficult to establish, scholars estimate that by the end of the first century, the Christian population across the Roman Empire may have been between 7,000 to 10,000 people. Some estimate 25,000. It is also estimated that there were about 40-100 congregations. This growth took place across hundreds of small communities, likely with each gathering made up of a few dozen believers. Larger urban centers may have had several hundred Christians meeting in multiple house churches, forming a loose but connected network within each city.
A Legacy of Community and Connection
So, how large were the New Testament churches? From a few dozen believers in a house to slightly larger city churches, the early church balanced small gatherings with the collective unity of a growing movement. These first-century Christians built communities that were close-knit, resilient, and deeply committed to their faith. As churches today look back, they find in these early gatherings a model of simplicity, relational warmth, and mission that still inspires the church’s understanding in our time.
