Welcome back to another episode of the unSeminary podcast. Today we’re joined by Dr. Warren Bird—author, researcher, and one of the most trusted voices in church leadership studies. Warren has co-authored over 35 books for pastors and church leaders, including Hero Maker, Better Together, Next, Resilience Factor, and his newest, Becoming a Future-Ready Church. Known for his deep data-driven insights, Warren has spent decades researching trends that shape healthy, growing churches.



What’s next for large churches in North America—and how are they shaping the future of ministry? How are they adapting after the pandemic? Are they thriving, struggling, or transforming in unexpected ways? Warren shares early findings from his newest national research study—The Large Church Survey 2025—which explores how churches of 1,000 or more are changing and what’s coming next for the future of the church.




* Exploring large church health. // Large churches have reshaped the landscape of ministry over the last fifty years. Yet following the pandemic, questions have emerged: Have they fully come back? Are they still growing disciples—or just attracting crowds? Warren’s latest study, available at bit.ly/largechurch2025, is designed to answer those questions by gathering data from churches with 1,000+ in-person attendance. The goal is to measure growth, transparency, discipleship, and community impact in a post-pandemic world.



* Cultural distrust of institutions. // Warren notes that many people today are skeptical of large organizations, including churches. Scandals, media coverage, and declining trust in institutions have fueled the perception that “big” means “impersonal” or “unaccountable.” Yet Warren argues that healthy large churches can be powerful forces for good—offering specialized ministries such as special needs programs, counseling centers, and community partnerships that smaller churches often can’t sustain.



* Early findings: community and young adults. // Although data collection is still underway, some surprising trends are already emerging. The second-highest area of growth since the pandemic has been churches’ service and impact on their local communities. Large churches are not retreating—they’re doubling down on outreach. Even more encouraging, the top area of growth is the spiritual response among young adults. Despite common myths, many large churches are seeing renewed engagement from people in their 20s and 30s who are hungry for spiritual depth and authentic community.



* The power of small groups. // One consistent trend across every five-year survey Warren has conducted since 2000 is the growing emphasis on small groups and teams. In the most recent data, 92% of churches give their highest priority to small groups as essential for discipleship and connection. Warren summarizes the insight simply: “You get bigger by getting smaller.” Large churches thrive when they help people move from rows to circles—building relational environments where faith grows deeper.



* Raising leaders from within. // Another major finding centers on leadership development. Among churches of 5,000 and larger, 92% report having a residency, internship, or formal leadership training program. The median number of participants per church is 15. This suggests that future pastors, missionaries, and ministry leaders are increasingly being raised up inside the local church rather than emerging solely from seminaries. Warren calls this a promising trend that could strengthen the next generation of church leadership.



* Comeback stories. // The data also reveals a surprising recovery among large churches. So far, 53% of churches with attendance over 2,
