Matthew 18 has become a refuge for scoundrels. Yes, Jesus taught us to forgive one another -- not seven times, or 70 times, but 70 times seven times. But that does not mean that if you steal from me 77 times you're entitled to recoil in holy offense when I call you a thief. That does not mean I can punch you in the face 489 times and then pretend I'm more righteous than you are because you demand that I stop.
