Matthew 18:15-20

 

 

 

Truly, this Gospel text is a hard teaching.  It’s harder than the one on forgiveness that we’ll get next week, the one that looks at forgiveness as a math problem, forgiving each other 70 x 7 times.  For some of us, today’s teaching is a harder cross to bear than the cross of persecution and death.  So you might ask, why is it so difficult?

 

It’s a hard text because it has a complicated history and use.  On the one hand, it can be used as a blueprint for how to build community.  But it also has a troubling history of being used to cast people out of community.  It doesn’t take much imagination to envision how a sociopath or a narcissist could use this text to get support for their views and to get rid of everyone who disagrees and will not conform to their world view.

 

For some of us, it’s hard because it seems so legalistic.  Bible scholars can show us that today’s Gospel is rooted in ancient Jewish law about how differences will be settled.  On its face, this Gospel doesn’t seem like the rule of love that Paul encourages in today’s passage from the letter to Romans.

 

For some of us, it’s hard because it reminds us that what we want to have happen—a quick resolution so we can all go back the way we were before—this outcome may not happen the first time we make an attempt.  Forgiveness and repair of relationships can be an arduous process—and the fact that Jesus doesn’t offer a quick fix makes it a hard teaching.

 

Today’s text reminds us that Jesus comes to earth for many reasons, but one of the most essential reasons is to show us how to live in community, not how to live for ourselves.  And today’s text tells us how to navigate one of the hardest parts of living in community—how to handle disagreements of all sorts, from the petty to ones more major.

 

The bad news is that we don’t automatically agree on what God wants, for us and for the larger world, just because we profess the same savior.  The good news is that we don’t have to do the work of resolving disagreements by ourselves. We don’t have to change ourselves to be what someone else wants us to be, but we can’t ignore, dehumanize, avoid, or just dismiss the one with whom we disagree.  We have to talk to them.  We can’t do what so many do in this age of social media, complain to everyone else except to the one with whom we disagree.

 

Jesus gives us an order of approaches, which involves more and more members of the community.  We’re involving others for several reasons.  Maybe we need witnesses.  Or maybe it’s because we’ll be more likely to work on a resolution in the company of others.  Maybe the other members of the community will see a way forward that those who are disagreeing do not see.

 

Involving others also helps everyone to have a spirit of discernment.  In a disagreement, it can be so easy to be sure that we are right, that we have been wronged.  A loving community can remind us of our part in the conflict, of the ways that we have not been innocent, the way we may have added fuel to the bonfire of disagreement.

 

We begin the work of reconciliation on a small scale, one on one, two by two, and then with the larger group.  If differences can be sorted out easily, no need to involve others.  But if it can’t, the resources of the larger group may be required.

 

In verse 17, the larger group is translated as “church,” which probably leads many of us to think of a group of folks, like this one, who gathers on a Sunday.  The Greek word is ekklesia, which is often translated as “church,” but the writer of the Gospel of Matthew would not have meant a church, like this one, but a much smaller group of people called by God, living together like the church in the book of Acts.  The church that Jesus creates in the first century is one forged in opposition and resistance.  The stakes of a disagreement can be much higher, truly life and death. 

 

Jesus’s life shows what happens when disagreements aren’t settled in the way that Jesus describes in today’s Gospel.  We know that some of his ekklesia of 12 disciples are not happy with decisions that Jesus makes.  We saw it last week with Peter wanting a different outcome for the ministry of Jesus, and we’ll see it in the Holy Week stories of Judas being so upset that he betrays Jesus to the authorities.  Judas shows what happens when disagreements are allowed to fester.

 

But the experiences of the other 11 disciples show a different path, and what a transformative path it is.  At the beginning of the book of Acts, we meet a traumatized group living in fear and isolation behind locked doors.  By the end, they have become a cohesive group that has gone out to declare the Good News of the life of Jesus and the love of God and the movement of the Holy Spirit.  Along the way, they’ve had many differences.  But Jesus has showed them how to manage those differences, and in the book of Acts, they handle disagreements in the way that Jesus taught them, although we only read about disagreements brought before the council at Jerusalem, the last arbiter of disagreements.

 

We say the disciples did great things because Jesus commissioned them, and that’s true.  But one of the less talked about reasons for their effectiveness is that they were able to be a cohesive community, the way Jesus taught them. They listened, they puzzled, they questioned, and occasionally, they disagreed—and then they listened and puzzled and questioned some more so that they could come to reconciliation.

 

I spent the week-end with a different ekklesia, a group of friends, at a Crafts for Christmas retreat at Lutheridge  It’s a small retreat of women from across the southeast, who have known each other for decades.  I think of us as “retreat friends,” but our bond is so much deeper.  We are women of faith, women who have spent our lives in the helping professions.  Talk turned, as it so often does with friends who are my age and older, to ways that life now seems worse than when we were younger.  Regardless of political affiliation, it’s not hard to make a case that life in previous decades seemed less perilous.  One of my friends said, “Is there anything right in the U.S. today?”

 

I said, “Well, my local public library is thriving, and every day they have a cool event or two, in addition to all the books we can borrow for free.”  Complete silence.  My friends stared at me.  I couldn’t tell if they thought I was delusional or if they wanted me to say more or to go back to our conversation rooted in despair.  I continued, “I don’t deny that there’s a lot that is wrong with the world—which is why I think it’s even more essential to remember all the things that are going beautifully.”  From there, the talk took a more positive direction, as we remembered all the ways that a community can change the world for the better.

 

When we aren’t willing to talk to each other, to sort out our disagreements so that we can come back to unity, even if we’re not in agreement, we get the world that my friends were seeing, a world without hope for the future.  If we are willing to talk, two by two or in front of larger parts of the community if need be, then we have the hope of building something beautiful, something that is part of God’s kingdom on earth that Jesus proclaims is near:  a public library or a retreat or a classroom or some other Christ-shaped community that can serve the world.

 

Yes, today’s Gospel is a hard teaching, particularly as it reminds us of how hard it can be to live in community.  Happily, Jesus assures us that we need not be afraid.  Jesus is with us, helping us as we heal our fractured world, as we gather together in groups of two or three or more, building something greater than the sum of ourselves, a community of inclusiveness that our world so desperately needs.
