When I read this passage from Luke I immediately remembered an exegesis paper I once wrote after reading an article by a doctor about what disease the woman might have. He concluded that she has a certain kind of arthritis—the same kind I had been recently diagnosed with. This gave me a sense of immediate connection with the woman in the story.
Such personal identification is homiletically useful.
I once read an article by a medical doctor who tried to identify the condition that kept the woman in Luke 13 crippled for 18 years. I don’t remember his methodology, and in retrospect it seems to me a dubious endeavor, but I was deeply interested in his conclusion: the woman suffered from an arthritic condition called spondyloarthritis.
