Today, our guest blogger is Mark D. Baker, who lives in Portland Maine and attends Rise Church. Rev. Kelly recently connected with Mark, as he wrote a book called Centered-Set Church; centered-set thinking resonates deeply with the vision of UniteBoston.
Below, Mark shares some of his personal experience, offering valuable insights on the perils of in-group and out-group thinking and how we can draw theological boundaries that faithfully uphold our convictions with compassion.
Cancel culture, us-them divisions, and line-drawing judgmentalism tear at the seams of society today. The way of Jesus offers an antidote, but before churches can offer the antidote to others, we must stop these practices ourselves. How can we leave judgmentalism behind, but still maintain a commitment to truth and biblical ethics? How can we appropriately make judgments between right and wrong without practicing self-righteous judgmentalism?
Youthful Judgmentalism
While riding home from church as a six-year-old, I looked disdainfully at people mowing their lawns; I had learned that Christians did not work on Sunday. I could draw a neat line between those who belonged to my religion and those who did not, just by looking at this one behavior. This gave me the security of knowing I was “in.” As I grew older, I continued to derive security from the lines I drew. As a teenager, I felt morally superior because, in contrast to those around me, I did not cheat on tests, steal on the job, drink, dance, swear, smoke, or do drugs. Unlike those on the other side of my lines, I was “in”––a good Christian.
The Problem is Judgmental Line Drawing, Not the Content of the Lines
At the Christian college I attended, I met some Christians who had a shorter list of rules than I did. They drank alcohol occasionally and enjoyed dancing. I faced a dilemma. My definition of Christianity told me they could not be Christians—at least, not good ones. In other ways, though, I recognized their faith to be more mature than mine. I concluded that the problem was legalism—putting too much focus on rules and strictly enforcing them. So, I became less legalistic. But had I really changed? Was I less judgmental? No, I had immediately drawn new lines. I looked down on legalistic Christians. Now they were the ones who were not “good Christians.”
Over the next several years, I embraced new expressions of Christian discipleship: a simple lifestyle, total commitment to Jesus, openness to gifts of the Spirit, and advocacy for social justice. I also continually drew new lines or added new criteria to the lines I used to define what constituted a good Christian. Just as I had disparaged those who mowed on Sunday, I now looked down on those who did not share my new perspectives.
I thought I had progressed as a Christian, but one day, through the prodding of a friend, I recognized I was just as judgmental as I had been as a six- or sixteen-year-old. I thought that legalistic rules were the problem, but it was the judgmental use of lines. Ceasing to draw lines would appear to be the solution. Many have erased the lines, but the resulting fuzziness creates new problems.
An Alternative: Orientation to the Center
Knowing I wrestled with this issue, a friend recommended I read an article by missiologist Paul Hiebert. He borrows categories from mathematical set theory to describe how groups determine who belongs and applies it to churches. A bounded church (left diagram) creates a list of essential characteristics that form a clear boundary line that determines whether a person is part of the group or not. Anyone who meets the requirements is considered “in.” I immediately recognized that I had practiced a bounded approach to Christianity. As seen in the diagram, a fuzzy church (right diagram) is the result of addressing the problem through line removal. Hiebert gave me language and diagrams for better describing my line-drawing judgmentalism and the ambiguity of the fuzzy option. More significantly, though, he introduced me to an alternative: a centered approach.


A centered group is created by defining a center and observing people’s relationship with the center–which in this case is Jesus. As the diagram with its arrows illustrates, instead of just judging a person by which side of a line they are on, a centered church looks at the direction the person is heading.

Jesus’ parable of the Pharisee and the tax collector in Luke 18 clearly displays the difference between a bounded and centered approach. Luke informs us that Jesus told this parable “to some who were confident of their own righteousness and looked down on everyone else” (18:9). In Hiebert’s terminology, we could say that Jesus told this parable to those using a bounded-group approach. According to a bounded approach, the Pharisee would be in—part of the group. The tax collector would be out—on the wrong side of the line. But referring to the tax collector Jesus says, “I tell you that this man, rather than the other, went home justified before God” (v. 14). How can Jesus say it is the tax collector who is justified, included, “in”? Because Jesus is looking at direction. A centered approach evaluates trajectory rather than just looking at compliance with a list of requirements.
Note that Jesus does not state that the Pharisee’s standards are wrong, it is his attitude toward others. Boundaries themselves are not the problem. Jesus himself draws boundaries between appropriate and inappropriate behaviors—like those listed by the Pharisee. The problem of the bounded church is using the boundaries to grasp for status and put others down. Through using boundaries to define the group, a bounded church ends up putting its identity and security in the lines drawn. A centered approach, through defining members by their orientation toward the center, naturally pulls people to put their identity and security in the center—Jesus. (See this article for a fuller explanation of the bounded, fuzzy, and centered approaches.)
A Resource: Examples of Practicing a Centered Approach
Excited by its potential to help students practice discipleship and ethics in less legalistic and judgmental ways, I introduced my seminary students to Hiebert’s work. Many students had experienced the shame of standing on the wrong side of a bounded church’s line. The possibility of an alternative excited them; some, however, felt nervousness. Does embracing a centered approach mean taking beliefs and standards less seriously? I first said, “No, that is what a fuzzy approach does.” After making the same clarification I did above—that to critique a bounded approach does not mean a rejection of boundaries—I gave the following example:
A centered approach to playing soccer would be inviting anyone who wants to play to gather at a local park on Saturday afternoon at three o’clock. In the diagram, those who show up are represented by the people whose arrows are heading toward the defined center, which is soccer. Those who do not show up to play are represented by the people whose arrows are turned away from the center. Some of those who show up may not be very good, but their lack of ability will not exclude them—their wanting to play shows their trajectory is toward the center.
I said to the students, “Suppose one of the players picks up the ball and starts running with it. What will the other players do?” A student responded, “They will say, this is not rugby, you can’t use your hands.” I asked, “What if the person does it again, and after further instruction does it a third time?” A student replied, “They will tell them they can’t play if they do not follow the rules.” I added, “Yes, because if they do not all follow the rules they will no longer be playing soccer. They will say, ‘we are playing soccer, you can come back whenever you are ready to play by the rules.’”

Similarly, a centered church must lovingly confront, and at times exclude, those whose beliefs or behavior hinder the community from living out the way of Jesus (Gal. 6:1; I Cor. 5:12). By discerning trajectory, a centered church has more space than a bounded church to walk with people in messy situations, but it does not water down standards.
As students more fully understood, they become curious about application; they asked, “What is the centered approach to dealing with ______?” (many things filled that blank, e.g., disagreement with the church’s doctrinal statement, a couple living together, and poor attendance at worship team rehearsals). They asked, “What do you do about membership in a centered church?” or “Don’t some things, like recovery ministry, have to be bounded?” I had no resource to recommend to them. Eventually I decided to write the resource I wished existed.
Before writing the book, I interviewed numerous church leaders practicing a centered approach. Their stories and insights fill the book. I invite you to read Centered-Set Church: Discipleship and Community Without Judgmentalism and join others in applying a centered approach to all aspects of ministry.
Unity with Other Churches: A Centered Approach
An individual church practicing the centered approach must define its center. In part that means differentiating between things of primary importance and secondary things about which there can be disagreement. Churches that have Jesus as their center will define their centers differently. For instance, they will have different practices of baptism. Rather than focusing on differences, as a bounded approach might pull us to do, a centered approach fosters unity across churches by focusing on what we have in common. That unity will grow as we recognize, that in relation to that common center, we are all heading the same direction.
This is not, however, just about diagrams and using different language like “trajectory.” Fundamental to a centered approach is relationship with the center. The shift in my attitude toward others, in my church and in other churches, flows from Jesus. Resting in the security of Jesus’ loving embrace, I feel less need to gain security and status by putting others down. A centered approach facilitates that shift, but in the end it is the work of the Holy Spirit.
Rather than being known as places of finger-pointing judgmentalism, my prayer is that we may become known for how we lovingly walk with people, toward Jesus, in their struggles and pain.
