5 Things Evangelicals Get Wrong About Mainline Churches

I used to think mainline churches were where faith went to die.

When people left evangelical churches for mainline congregations, we whispered that they’d “gone liberal” like it was a diagnosis of some terminal illness. Then, I found myself on staff at the largest mainline church in North America, and I discovered that almost everything I’d been told was either wildly exaggerated or completely backwards.

The Narrative I Inherited

The story I grew up with was that evangelical churches were Bible-believing, Spirit-filled, growing communities of genuine believers. Mainline churches were theological museums, preserving the forms of Christianity while abandoning its power. They’d compromised with the world, prioritized inclusion over truth, and were slowly dying as God’s judgment on their unfaithfulness. They were to be avoided at all costs.

When I finally stepped into a United Methodist church, I was shocked to discover a community that loved scripture, pursued holiness, served their neighbors sacrificially, and worshipped with genuine joy and reverence. They just did it all differently than I’d been taught to recognize as “real” Christianity.

Five Misconceptions

1. Mainline churches don’t believe the Bible

This is the foundation of almost every other misconception, and it’s fundamentally backwards. Mainline traditions actually take the Bible more seriously in many ways because they study its historical context, original languages, and literary forms instead of flattening everything into propositional theology. I like to say that you don’t have to take the bible literally to take it seriously.

I remember the first time someone explained to me that Genesis 1 uses ancient Near Eastern cosmology. The seven-day structure, the dome of the sky holding back waters above, the ordering of chaos into creation. These were the theological language of the ancient world being used to make profound claims about who God is and what creation means. Understanding that doesn’t diminish scripture. It honors what the text actually is.

When mainline scholars study Paul’s letters as occasional correspondence written to specific communities facing particular problems, they’re not reducing scripture’s authority. They’re taking it seriously enough to ask what it meant in its original context before applying it to ours. That’s more careful biblical interpretation if you ask me.

2. They’ve abandoned evangelism for social justice

This one makes me tired because it assumes social justice and evangelism are separate categories, which is a thoroughly modern evangelical invention. Jesus talked constantly about economic systems, treatment of outsiders, and power dynamics. His first sermon in Luke 4 was announcing good news to the poor and freedom for the oppressed.

When mainline churches address housing inequality or immigration policy or environmental destruction, they’re recognizing that gospel proclamation without concern for people’s actual material conditions is exactly what James called dead faith. You can’t tell someone God loves them while supporting systems that crush them. That’s the definition of hypocrisy.

And mainline churches are doing evangelism, just not the way evangelicals recognize it. Instead of the sales pitch model focused on getting people to pray a “sinner’s prayer”, mainline evangelism looks like sustained presence in communities, meeting real needs without strings attached, and inviting people into authentic relationship over time. It’s slower. It’s less measurable. It doesn’t produce impressive conversion statistics. But it’s deeply rooted in how Jesus actually operated. He spent three years with twelve guys. He fed whoever showed up hungry. He touched lepers and talked with Samaritans and let his life be interrupted constantly by people’s needs. That’s the model mainline churches are following, and I find it so refreshing.

3. Their worship is cold and dead

This mistake confuses aesthetic preference with spiritual depth, and I get it. I grew up with contemporary worship bands, fog machines, raising hands, and crying during the “altar call.” That felt alive to me because it was emotionally demonstrative and I could measure my own engagement by how much I felt.

Mainline liturgy operates differently though. It connects worshippers to two thousand years of Christian tradition through practices the global church has always valued. When you pray the Lord’s Prayer or recite the Apostles’ Creed or celebrate communion with the same ancient words, you’re joining your voice to the communion of saints across time and space.

The prayers that feel repetitive to evangelicals are actually profound theological formations. Julian of Norwich prayed these words. Dietrich Bonhoeffer prayed them in a Nazi prison cell. Korean Christians prayed them under persecution. Your great-grandmother prayed them in a small country church. When you pray them, you’re not alone. You’re part of something bigger than your individual experience, connected to believers across centuries who held onto faith through circumstances you can’t imagine.

There’s tremendous power in liturgy precisely because it doesn’t depend on your emotional state in the moment. On days when you can’t find words, the liturgy speaks for you. On days when you doubt everything, the creed reminds you what the church has always believed. On days when you feel isolated, the responsive readings connect you to every other person praying the same prayers. If that’s dead, I don’t know what alive means.

4. They don’t have theological standards

This one reveals how little evangelicals actually know about mainline denominations, and it’s almost funny because the reality is exactly opposite the stereotype.

United Methodists have the Wesleyan Quadrilateral, which provides a sophisticated framework for theological reflection using scripture, tradition, reason, and experience in dialogue with each other. I wrote about that here.

It’s a method for wrestling with complex questions while staying rooted in biblical authority and church tradition.

Presbyterians have the Book of Confessions, a collection of historic Reformed statements from the Nicene Creed to the Confession of 1967 that shape how they read scripture and practice faith. These documents have been tested and refined over centuries. They represent the collective wisdom of the church discerning together what faithfulness looks like.

Lutherans have the Augsburg Confession and the Book of Concord. Episcopalians have the Book of Common Prayer and the Chicago-Lambeth Quadrilateral. The Disciples of Christ have their commitment to no creed but Christ, which is itself a theological standard about how authority functions in the church.

These are substantive theological commitments that shape everything from ordination standards to worship practices to how conflicts get resolved. There’s accountability, oversight, connection to historic Christianity, and processes for theological discernment that involve more than one pastor’s interpretation.

Meanwhile, many evangelical churches operate with whatever the senior pastor decided last week is biblical truth. Truly. (I used to be in that position) No connection to broader tradition. No accountability to anything beyond the local congregation. No framework for testing individual interpretations against two thousand years of Christian thought. The pastor says God told him something, and that’s the final word. Tell me again who lacks theological standards. Pfft.

5. They’re dying because they compromised

The narrative says mainline churches are dying because they abandoned biblical truth. The reality is more complex and more hopeful than that story allows.

Yes, mainline denominations have declined numerically since the 1960s. That’s undeniable. But here’s what the stereotype misses. Recent data from Lifeway Research shows that 46% of mainline Protestant churches are currently experiencing growth. Not explosive megachurch growth maybe, but genuine, steady increase in worship attendance and new commitments to Christ. Methodist churches are seeing 43% growth rates, Lutheran churches 37%. That doesn’t sound like dead institutions to me. They’re living communities doing the slow, faithful work of discipleship.

What if the narrative about mainline decline has always been incomplete? What if some churches are shrinking not because they compromised but because they refused to compromise? Because they welcomed LGBTQ people when it cost them donors. Because they spoke against Christian nationalism when it cost them members. Because they pursued racial reconciliation when it made people uncomfortable. That’s faithfulness that costs something, and that is okay.

The early church didn’t grow because they had relevant programming or contemporary worship. They grew because they embodied radical enemy love and economic sharing that looked nothing like the surrounding culture. They cared for plague victims when everyone else fled. They welcomed outsiders and crossed every social boundary their world had erected.

Some of the most spiritually vital communities I know are small mainline churches that chose gospel integrity over institutional survival. They’re proof that vitality isn’t measured in numbers. It’s measured in faithfulness to Jesus, even when that faithfulness is costly. And right now, with nearly half of mainline churches experiencing growth while staying committed to justice and inclusion, maybe we’re seeing seeds that were planted in faithful soil finally bearing fruit.

Why This Matters

I’m not writing this to trash evangelicalism or convert everyone to mainline Protestantism. I’m writing it because these misconceptions keep people trapped in toxic church environments thinking there’s no faithful alternative. They keep people abandoning Christianity entirely when they could be discovering rich, life-giving expressions of faith in mainline traditions.

The truth is that American Christianity needs both evangelical energy and mainline depth. We need revival movements and historic liturgy. We need passionate evangelism and thoughtful (healthy) theology. We need contemporary innovation and connection to the communion of saints across time. I wrote about some things that evangelicals and mainline churches can learn from each other here.

But we can’t get there while we’re making stuff up about each other.

If you’ve been taught that mainline churches are theological wastelands, I’d encourage you to actually visit one. Be genuinely open to encountering Jesus there. You might be surprised by what you find. You might discover, as I did, that the gospel you thought you’d left behind was actually waiting for you in an ancient liturgy, a thoughtful sermon, and a community that’s been faithfully following Jesus long before contemporary evangelicalism existed.
