Nancy Gibbs gave a wonderful speech which was adapted for TIME magazine titled How we Deserted Common Ground. The piece is directed to journalists but is worth reading because she is a very good writer and her insights are always helpful.
In Gibbs' article she cites Yale Law professor Dan Kahan who said, "What people 'believe' about global warming doesn't' reflect what they know, it expresses who they are." Clearly this is not limited to global warming. To make the case, Gibbs also cites a southern Democratic Senator who said the debate over gun control is "about who you are and who you aren't."
When we are more concerned about our personal brand, our ratings, number of likes, and retweets, every issue is not about the issue but a proxy discussion for how we desire to be seen. It stands to reason that the debates in the United Methodist Church are also about "who you are and who you aren't."
And therein lies the difficulty of the situation we are in. We are so insecure of who we are in Christ that we have to constantly define ourselves as something else. "We are orthodox Wesleyan." "We are the prophetic voices of God." We are arguing with others in order to show them who we are, all the while unaware that who we really feel we need to convince is is our own tribe.
A large reason we continue to be entrenched is because if we give the impression that we are not 100% with our tribe then we risk our tribe abandoning us. And hell hath no fury as a tribe who eats their own for not being pure enough for the tribe. So in order to avoid being cannibalized by our own tribe, we take steps to prove our tribal devotion which moves us farther away other non-tribe members.
This is why we all have words and ideas that we don't like to use. Conservatives do not like to identify themselves as social justice advocates (even though they they are) because even as they believe in social justice they don't want to give the impression they are liberal. And Liberals don't want to talk about how they are orthodox (even thought they are) because to do so means they could give the impression they are conservative.
Much of the arguing in the church that divides us farther apart is rooted in efforts to convince our own tribe of who we are. And there is no greater devotion to the little tribe than being willing to break the larger Church for the sake of the little tribe.
