my brother Steve (an ex STAS seminarian himself, received all the Minor Orders) had a self-donated marrow transplant for his lymphoma, but it didn't work. It was a very unpleasant and painful experience for him. He regretted it later.
Well, maybe there's something Providential about this. As a positive, I noticed my dad was wearing a cross pendant again at Christmas, so maybe the face of mortality is making him "relapse" back toward his childhood Catholic faith again. God-willing. He has an in-road back through me, he just needs to act on it.
