The Beautiful Complexity of God’s One Church

There’s a famous quote often attributed to Gandhi: “I like your Christ, but I don’t like your Christians.” It’s a sentiment that resonates uncomfortably with many of us today. Even those who deeply love Jesus sometimes struggle with the church—its messiness, its hypocrisies, its failures. Some have decided to abandon organized religion altogether, declaring, “I’ll follow Jesus, but I’m done with the church.”

But what if walking away from the church means walking away from something Jesus himself is radically committed to?

The Mystery of the One Church

The Nicene Creed, written seventeen centuries ago, makes a startling claim: “We believe in one holy, universal, and apostolic church.” Not churches, plural. Not denominations competing for spiritual market share. One church.

This isn’t referring to any particular organization or denomination. The word “catholic” in the creed doesn’t mean Roman Catholic—it simply means universal, from the Greek word katholikos, meaning “the whole.” The Apostle Paul described it beautifully when he wrote to the Corinthians: “To the church of God in Corinth, to those sanctified in Christ Jesus and called to be holy, together with all those everywhere who call on the name of our Lord Jesus Christ—their Lord and ours.”

That phrase “all those everywhere” captures something breathtaking. The church existed long before any of our current congregations were founded, and it will continue long after they’re gone. Every local church is simply a temporary expression of something eternal—the one body of Christ scattered across time and space.

Built on an Unshakable Foundation

What makes this diverse, global, multi-generational body one church? The foundation.

Ephesians 2:19-22 paints a vivid picture: “Consequently, you are no longer foreigners and aliens, but fellow citizens with God’s people and members of God’s household, built on the foundation of the apostles and prophets, with Christ Jesus himself as the chief cornerstone.”

The church is apostolic because it’s built on the teaching of the apostles—the message preserved for us in the New Testament. This isn’t about organizational succession or special authority passed down through history. It’s about faithfulness to the original message. When Paul wrote to Timothy, he emphasized this chain of transmission: “The things you heard me say in the presence of many witnesses entrust to reliable people who will also be qualified to teach others.”

Four generations in one sentence—Paul to Timothy to reliable people to still others. The apostolic deposit isn’t about who ordained whom; it’s about guarding and passing on the truth of the gospel.

Called Out, Made Holy

The church is also described as holy. But what does that mean when we’re painfully aware of our own failures and the failures of fellow believers?

Holiness begins with God’s action, not ours. The word “church” comes from the Greek ekklesia—literally, “the called-out ones.” In ancient Athens, citizens would be called out from their homes and businesses to assemble for civic matters. God has called us out from our former identities, our former allegiances, our former lives. “You are no longer foreigners and aliens,” Paul declares. Our citizenship has changed. Our primary identity is no longer our nationality, ethnicity, political affiliation, or socioeconomic status. We are, first and foremost, God’s people.

This is radical. The Apostle Paul, who once defined himself as “a Pharisee of Pharisees,” threw all his former identity markers on the garbage heap. Everything that once defined him became worthless compared to knowing Christ.

But being called out has implications for how we live. God’s holy temple cannot be filled with moral impurity. The church derives its morality not from the surrounding culture but from the unchanging word of God. What is true, beautiful, and good doesn’t shift with cultural trends—it’s rooted in the eternal character of God himself.

This creates friction. When everyone around you is participating in cultural practices that contradict God’s word, saying “I can’t do that” becomes costly. Yet this is precisely what it means to be holy—set apart for God’s purposes, living by his standards rather than the world’s ever-changing opinions.

Unity in Diversity

Perhaps the most challenging aspect of the “one church” is actually maintaining unity. The passage in Ephesians emphasizes this repeatedly: fellow citizens, one household, one foundation, the whole building, joined together, one temple, built together. Unity is woven through every phrase.

But here’s the beautiful complexity: our God is one, yet he exists as three persons—Father, Son, and Holy Spirit. Unity doesn’t mean uniformity. The Trinity models unity-in-diversity, and the church reflects this reality.

Paul uses the metaphor of a cornerstone to illustrate this. Two walls—representing Jews and Gentiles, two groups that couldn’t be more different—are joined together because they’re both connected to Christ, the cornerstone. When you’re properly aligned with the cornerstone, you can’t be off at your own angle. You’re brought into alignment with others who are also connected to him.

This means God isn’t calling people from just one nation, one ethnicity, one background. He’s pulling people from everywhere and making them his. There is neither Jew nor Gentile, slave nor free, male nor female—there is Christ, and he is everything.

The Hard Work of Unity

But maintaining this unity requires effort. In Ephesians 4, Paul writes, “Be completely humble and gentle; be patient, bearing with one another in love. Make every effort to keep the unity of the Spirit through the bond of peace.”

Make every effort. It’s not automatic.

In our age of social media outrage and tribal thinking, these words feel almost quaint. Humble? Gentle? Patient? Bearing with one another? We’ve put divisiveness on steroids, and sadly, some of the harshest conflicts happen between Christians.

Paul’s instruction is clear: submit your personal preferences to the more important reality of unity in Christ. When the Corinthians asked about eating meat sacrificed to idols, Paul didn’t give a simple yes or no. He spent three chapters explaining that it depends on how it affects others. “If it would harm a brother or sister,” he essentially said, “I will never do it.”

Unity, love, and humility often require nuance, patience, and thinking the best of others rather than rushing to judgment.

Why the Church Matters

So why does all this matter? Can’t we just have a personal relationship with Jesus and skip the messy church part?

The problem is that Jesus himself is radically committed to the church. He’s not starting another temple or taking another bride. This is his body, and he’s not abandoning it despite its flaws.

Yes, the church has hypocrites. It has people who hurt others. It has covered up sins and fallen short in countless ways. And here’s the hard truth: it will continue to do so until Jesus returns, because wherever human beings are involved, sin will be present.

But here’s the thing—every organization has hypocrites. Every workplace, every community group, every family. The question isn’t whether we’ll encounter flawed people; the question is whether we’ll commit to the community God has specifically called us into.

The church is God’s chosen instrument for our sanctification. The very friction we experience with other believers—especially those different from us—is often the means by which God shapes us into Christ’s image. Just as a lifelong marriage teaches patience and selflessness in ways a short-term relationship never could, long-term commitment to a church body refines our character.

When we gather at the Lord’s table, we’re not just performing a ritual. We’re joining with believers across the globe and throughout history, proclaiming that one Lord, one faith, one baptism unites us. We’re declaring that what brings us together is infinitely greater than anything that divides us.

The sun never sets on the church of Jesus Christ. Right now, somewhere in the world, believers are gathering, worshiping, taking communion, proclaiming the same gospel. We’re part of something vast, ancient, and eternal—the one holy, universal, and apostolic church.
