If you want your church to strengthen relationships, reach the community, and grow, you need to understand one of the most important communication theories for ministry today: Media Multiplexity Theory (MMT). It explains why some churches thrive, some maintain, and others decline—based on how well they communicate.
The best part?
You can understand the entire theory in one page.
What Is Media Multiplexity Theory?
Developed by Caroline Haythornthwaite (2002), Media Multiplexity Theory says:
Strong relationships use more communication channels.
Weak relationships use fewer.
Latent relationships use none—yet.
MMT is built on three key ideas:
1. Strong ties require multiple channels
Families, close friends, committed groups—they stay connected through:
- Face-to-face interaction
- Phone calls
- Texting
- Social media
- Video meetings
- Livestreams
- Messaging apps
The more channels they use, the stronger the relationship.
2. Weak ties rely on one or two channels
These relationships exist, but barely.
Examples:
- Someone who only sees your church on Facebook
- A neighbor who only remembers your billboard
- A community member who saw a mailer once
Weak ties are important because they are the doorway to new connections—but only if nurtured.
3. Latent ties are relationships waiting to happen
Latent ties are people who could be connected with your church but aren’t because no channel reaches them.
Examples include:
- People living within 5 miles of the church
- Parents at nearby schools
- Community members who visit your website but never hear from you again
- People who interact with your community partners but never hear about your church
- Anyone who could find spiritual life through your church—if communication was consistent and diverse
In short:
MMT helps churches activate latent ties, strengthen weak ties, and reinforce strong ties.
Why This Theory Matters for Churches
Your dissertation confirmed what MMT predicts:
- Churches using 3+ communication channels show stronger engagement.
- Churches with fewer channels show weaker connections and lower attendance.
- Churches with inconsistent communication see relational drift and declining relevance.
Think about what this means theologically:
- Discipleship requires relationship.
- Relationships require communication.
- Communication requires multiple channels.
MMT is not just a communication theory—it’s a ministry strategy.
Practical Example for Churches
Imagine two churches:
Church A uses two channels:
- Pulpit announcements
Church B uses six channels:
- Pulpit announcements
- YouTube/Livestream
- Email newsletter
- Texting platform
Church A is likely to reach:
- members
- a few former members
- a few casual Facebook followers
Church B is likely to reach:
- members
- former members
- inactive members
- neighbors
- digital visitors
- community partners
- seekers online
- unchurched families
- parents in local schools
Church B isn’t “better”—it’s connected.
More channels = more relationships = more opportunities for ministry.
Why MMT Explains Church Growth
Church growth is relational, not mechanical.
MMT helps explain why some churches grow while others decline:
- Growth happens when relational ties strengthen.
- Relational ties strengthen when communication channels multiply.
This is exactly what your statistical models demonstrated across 25 churches.
The One-Page Summary
Here it is in one sentence:
If your church wants stronger relationships, broader reach, and deeper engagement, you need to use more communication channels, more consistently, with more intentionality.
This is Media Multiplexity Theory—simple, practical, and transformational for ministry.
