Matthew 18:15-20 New Revised Standard Version (NRSV)
15 “If another member of the church sins against you, go and point out the fault when the two of you are alone. If the member listens to you, you have regained that one. 16 But if you are not listened to, take one or two others along with you, so that every word may be confirmed by the evidence of two or three witnesses. 17 If the member refuses to listen to them, tell it to the church; and if the offender refuses to listen even to the church, let such a one be to you as a Gentile and a tax collector. 18 Truly I tell you, whatever you bind on earth will be bound in heaven, and whatever you loose on earth will be loosed in heaven. 19 Again, truly I tell you, if two of you agree on earth about anything you ask, it will be done for you by my Father in heaven. 20 For where two or three are gathered in my name, I am there among them.”
What responsibility do we have for each other? If someone sins against us (does something to harm us or another) do we have a responsibility to pursue a resolution, and what is it we should pursue? Justice (whatever that means) or reconciliation or something else? Do we have a responsibility to correct a brother or sister, if we see they are taking a spiritually dangerous path? Questions like these ask us to consider the nature of our relationships within the church. In essence they are similar to the question that Cain asked about Abel – Am I my brother’s keeper? What would Jesus say?
