When there's a power differential, I think Matthew 18 should not be used. The word is sibling, brother and sister. This is a family relationship. This is not a hierarchy. I think that this is about ordinary inter-human relationships.
I don't think that this is a text that solves all conflict management theory. This is about an interpersonal breakdown. My contention is that churches misuse this. as a template for everything that happens that needs to be reconciled.
And it's a mistake. It is wise to go one-on-one before you go to Twitter. And it's right.
But people go to Twitter because the one-on-one didn't work. And in a sense, the prayers didn't work. And the two or three didn't work.
And the church is ignoring the situation and trying to hide it behind closed doors. And a person gets desperate and they go public. Most of the situations that you and I know about in churches today only worked out for justice because someone went public. That is a sad description of the church's, Christian institutions'willingness to handle allegations with integrity and vulnerability.
