Forty-three percent of Gen Z identifies with no religion at all. Yet sixty percent of all Americans still call themselves Christian. Something doesn’t add up.
According to Barna’s latest research, we’ve reached a startling threshold: while 60% of U.S. adults claim Christian identity, only 24% qualify as “practicing Christians”—those who attend worship monthly and say faith is “very important” to their lives. The largest religious group in America isn’t evangelical Christians or Catholics. It’s nominal Christians—people who believe the right things but live as if they don’t.
The Crisis of Nominalism
This isn’t just a statistic. It’s a spiritual pandemic. Millions of Americans carry the name of Christ on their identity but live functionally secular lives. They believe in Jesus the way they believe in George Washington—an important historical figure who probably existed and did some good things. But He doesn’t shape their daily decisions, their relationships, their spending, or their priorities.
Ryan Burge, political scientist and pastor, argues in his new book The Vanishing Church that the “moderate middle” of American Christianity hasn’t just shrunk—it has largely disappeared. Those who once identified as Christian out of cultural habit now identify with no religion at all. The chasm between affiliation and practice is the defining challenge of our moment.
Here’s the uncomfortable question: What if the church has been optimizing for the wrong metric? We’ve counted attendance, measured giving, tracked membership rolls. But Jesus didn’t command us to make attendees. He commanded us to make disciples.
‘The church is the body of Christ, and the body grows not by addition but by multiplication. Every member is a minister, every Christian a priest, every saint a missionary.’
From Consumer to Disciple-Maker
The nominal Christian problem isn’t primarily about knowledge—it’s about formation. Most non-practicing Christians still affirm core doctrines. They believe Jesus is the Son of God. They believe He rose from the dead. They just don’t believe it matters enough to reorient their lives.
This is where the multiplication mindset changes everything. 2 Timothy 2:2 isn’t just a mission statement—it’s an operating system: “And what you have heard from me in the presence of many witnesses entrust to faithful men, who will be able to teach others also.” Four generations in one verse. Paul to Timothy to faithful men to others also. The gospel spreads not through professional clergy but through ordinary believers who disciple others who disciple others.
When we shift from a consumer model to a multiplication model, nominalism dies. You cannot consume your way into maturity. You cannot attend your way into mission. You can only disciple your way there.
The Three-Generation Test
Here’s a diagnostic tool I use with church leaders: The Three-Generation Test. Look at your church’s discipleship pathway and ask:
- First Generation: Are new believers being intentionally discipled one-on-one or in small groups?
- Second Generation: Are those disciples making disciples—equipped and released to lead others?
- Third Generation: Are their disciples doing the same?
If you can’t trace discipleship three generations deep, you have a consumer church, not a multiplication movement. You have nominal Christians, not practicing disciples.
The early church understood this. Church historian Justo González notes that within three centuries, Christianity spread from a marginal Jewish sect to the official religion of the Roman Empire—not through marketing campaigns or political power, but through ordinary believers who lived their faith so contagiously that their neighbors wanted what they had. They didn’t have church buildings. They didn’t have professional worship bands. They had disciples who made disciples who made disciples.
‘The preaching of the cross is to them that perish foolishness; but unto us which are saved it is the power of God.’
Practicing What We Claim
So how do we move from label to life? How do we close the gap between 60% Christian identity and 24% Christian practice?
First, redefine success. Stop counting seats and start counting sent. Measure not how many show up but how many are equipped for works of service (Ephesians 4:12). The goal isn’t a full sanctuary—it’s a city transformed by disciple-makers.
Second, prioritize reproducibility over impressiveness. Simple disciple-making tools spread faster than complex programs. If your discipleship model requires seminary training, it won’t multiply. If it requires a forty-week commitment, it won’t multiply. Look for methods that ordinary believers can replicate in their living rooms, break rooms, and neighborhoods.
Third, disciple toward mission. The end goal isn’t biblical literacy—it’s biblical obedience. Knowledge that doesn’t lead to action puffs up. Discipleship should always be oriented toward making Jesus known, not just knowing more about Jesus.
The Multiply Movement, based on Francis Chan’s vision, offers a free 24-session curriculum specifically designed for this: ordinary Christians equipped to disciple others, who then disciple others. It’s not flashy. It doesn’t require a stage or a soundboard. It requires believers who will open their homes, open their Bibles, and open their mouths to share what God has done.
Your Move
The gap between claiming and practicing Christianity isn’t a problem to be solved by better preaching, bigger buildings, or slicker social media. It’s a problem solved by ordinary believers who take 2 Timothy 2:2 seriously.
Maybe you’re a nominal Christian reading this. You’ve claimed the name but lived distant from the practice. Here’s good news: The blessed life begins with emptiness that Christ fills. You don’t need to clean yourself up before approaching Him. Just come.
Maybe you’re a practicing Christian wondering if you’re making a difference. Here’s your encouragement: Disciple one person. Don’t worry about changing the world. Worry about changing one person’s world. Then teach them to do the same.
Maybe you’re a church leader tired of counting attendance while the culture drifts further from the gospel. Here’s your pivot: Cancel a program. Free up your best leaders. Send them to make disciples who make disciples.
The American church doesn’t need more nominal Christians. It needs practicing disciples who multiply. That’s how the gap closes—not one percentage point at a time, but one disciple at a time.
