“Unclean! Unclean!”

That cry—the cry of the leper—struck terror into the hearts of passersby in Palestine at the turn of the Common Era.

In medieval Europe that cry separated the leper from everything he or she loved and enjoyed, condemning the leper to a kind of living death.

Today, even well-educated folk grimace at the sound of the word “leprosy” and shrink at the thought of a disease associated with all that is evil and terrible.

Yet, for most of us, leprosy is either very long ago or very far away. Often it has only biblical associations. We visualize Levitical priests examining people with ancient diseases, or Jesus healing people on society’s fringe—outcasts to both the medical profession and the religious establishment.
