Something that resonated was the Scripture (Luke, I think) about "the man covered in leprosy" who said to Jesus "if you want to" you can make me clean.
I'm not going to get into what the actual disease was, whether it was Hansen's disease or some other. I think leprosy here is a metaphor for Sin (with a capital S). Not sins, but the Big Enchilada. Everybody go "Ewwwwwww", in unison. I think that the response we were intended to have. Leprosy, or any infectious disease, provoked that same reaction. Disease etymology (or do I mean etiology) was poorly understood. Disease or dis-ease was caused by little demons. Now we know that it is caused by little organisms (you knew I would go there) called germs. Modulo resistant strains, we have remedies that the ancient world did not. Rather, more effective, more humane than ostracism or indeed pistachios, which is what autocorrect would insist upon. (Sorry, I couldn't resist. )
So what makes us go Ewww? It varies. Google pharmakos. For the lazy among us, I'll define it. Scapegoat, in a word. The pharmakos, from which root we get pharmaceuticals etc, was that poor unfortunate who was selected as the "author of all our ills" and ended up being killed, usually fairly nastily. Made society feel so much better.
Modern pharmakoi include: the Jews (in certain unrespectable circles), the mentally ill (why can't we just conform), communists (back in the 50s), terrorists, and bullies. These are all groups which have exercised the imaginations of people afraid of the dark. Why are we afraid of the dark? Because of what is in it. I wander off topic, but I think it has something to do with death.
In my (private) Ignatian retreat rant, I made much of how icky homeless people are. As Christians (of whatever flavor), we are not supposed to feel this way, but I almost think society can't function without -somebody- to fill this role. We strive to move people out of the pharmakoi position, but other groups fall into that niche. We talk about feeding the homeless, but we should really bathe and groom them and find more comfortable places for them. Sleeping in park benches is not pleasant. We need to do more.
Perhaps we should build more prisons. Not.
The boogeyman gets a lot less scary when we can laugh. Maybe we don't need to be afraid. Death -is- inevitable, after all.
