Dr. Martin Luther King, Jr., knew his bible, and he got it right when he preached on the parable of the Good Samaritan. (He was assassinated one day after he preached on it: all of us seem to be forever traveling the dangerous road from Jerusalem to Jericho.)
You can read Dr. King’s words on the cover of our bulletin, but here’s the thumbnail: the priest and the Levite choose not to help the man in distress for perhaps one or two specific reasons. They may have other priorities (even virtuous priorities!), or they may simply be afraid. But the Samaritan chooses to help because he asks a better question of himself than the other two. In Dr. King’s imagination, the priest and the Levite (incidentally, in our church context, “priest and Levite” would roughly compare to me and one of our lay Eucharistic ministers) –they wonder what would happen to them if they stopped to help, but the Samaritan wonders instead what would happen to the guy in the ditch if he didn’t lend a hand.
