From historic cathedrals to storefront congregations, Chicago is one of the most diverse cities for Christianity in the world. Among these, interdenominational churches have a unique goal—aiming to bring believers together beyond denominational tribes.
On the surface there may not be much nuance between ‘non-denominational’ and ‘interdenominational’, since both represent a departure from historic church groups. The main differences may be in emphasis, although in some instances, they will be profound.
‘Non-denominational’ is simply the absence of membership to an established denomination. Although these churches tend to have other types of affiliations.
‘Interdenominational’, on the other hand, is often a more intentional effort to bridge the gap between Christians of various traditions. In reality, a lot of churches often reflect aspects of both.
Let’s explore the topic in more detail.
What Is an Interdenominational Church?
An interdenominational church is a congregation that gathers and integrates people from different Christian backgrounds—such as Baptist, Methodist, Pentecostal, Congregational, Lutheran, Anglican, Presbyterian, or Catholic.
Rather than aligning with one specific tradition, interdenominational churches typically focus on:
- The importance of unity.
- The centrality of Jesus.
- Core traditions across denominations.
Achieving unity is not always easy to navigate. In ideal circumstances, an interdenominational church purposefully connects the various traditions of its members in a way that honors and celebrates those differences.
Interdenominational vs. Non-Denominational Churches in Chicago
It’s easy to be confused by the differences between interdenominational churches and non-denominational churches in Chicago. While the terms are closely related and sometimes used interchangeably, there is still a distinction.
Chicago is home to both traditional and progressive churches. One may conclude that interdenominational’ is automatically less traditional, but that assumption could prove false.
- Interdenominational churches intentionally acknowledge and value multiple Christian traditions. For example, various methods of infant baptism may be allowed, Mary may be more highly venerated, or communion may be offered according to different practices. Traditional liturgies are not uncommon.
- Non-denominational churches operate independently from historic groupings, avoiding formal denominational identities, yet still typically fall within a certain theological framework, often ranging between baptist and pentecostal. They would predictably be far less Anglican, with informalities that are still sincere.
Even though these labels are somewhat useful, in real life there is still a lot of wiggle room in their application. Each church will have unique convictions as well as emphasis. Even written website statements can be incomplete or misleading. Hearing one sermon will often not clarify the subject. The best way to understand what these labels mean is to directly ask the church leaders and press for clarity.
Interdenominational Churches in Chicago
The city’s neighborhoods have incredible diversity: cultural, ethnic, as well as theological. Those who begin to explore Christianity—often lacking context for its various traditions—may be attracted to the message of unity proposed by interdenominational churches.
Interdenominational can be appealing because it promises:
- An opportunity for diverse Christians to come together.
- Spiritual flexibility, rather than institutional boundaries.
- A context for those who distrust mainline denominations.
This approach can appeal to many. Yet, like all things, it is not without its challenges.
What to Expect at an Interdenominational Church
Even though each church will be unique, many interdenominational churches share common characteristics that can make them approachable.
Incorporation of Scripture
Services are typically not shy on Scripture, although interpretations may vary considerably. The teaching will likely emphasize grace and following Jesus in the modern world.
Shared Worship
Worship styles will always vary across churches—some will be contemporary, some blended, some more reflective or traditional—but the goal is usually the same: to focus on God and invite people into true worship regardless of their background.
Diverse Community
You’ll likely find people from various walks of life and different traditions. This diversity is often celebrated as a strength rather than a challenge.
Focus on Service
In Chicago, interdenominational churches typically value their neighborhoods—addressing practical needs, developing relationships, and being a visible expression of love.
The Inherent Challenge For Interdenominational Churches
Interdenominational churches have a compelling goal: to create space where Christians from different backgrounds gather together. That instinct is admirable. In a fragmented church landscape, the desire to lower barriers can open doors for people who might otherwise remain distant from church altogether.
At the same time, that openness carries a natural tension. When a church draws from multiple traditions, it must constantly discern how much energy to allocate in a certain direction, without drifting into confusion or clutter. A lack of theological anchoring can produce uncertainty about what the church actually believes and practices.
Key challenges include:
- Maintaining doctrinal clarity.
- Avoiding theological vagueness.
- Helping attendees understand beliefs and practices.
- Navigating opposing expectations around worship and sacraments.
This is the inherent challenge for interdenominational churches: holding together clarity and openness without losing either. Unfortunately, over time, the result can be ambiguity and dissatisfaction. Because every group wants to be heard and valued, no group feels heard or valued.
A church should exist to help people encounter Jesus, grow in their faith, and live a gospel-centered life. Denominational expectations may inhibit that through rigidity, just as interdenominational blending may through ambiguity. Unity is not the ultimate marker if what we unite around is misguided.
How to Find the Right Church in Chicago
When searching for a church, consider asking:
- Is the Bible central?
- Do they clearly communicate beliefs and values?
- Is the community welcoming?
- Are there opportunities to grow and connect?
- Does the church care about the city?
Watching sermons or services online can help discern whether a church is the right fit. However, there is nothing more important than visiting in person and connecting with leaders and members.
A Place to Belong and Grow
