My wife and I have had similar experience, multiple times (over a ~30 year time span), with our churches' people bringing us meals to help us after surgeries. They, ummmm, overwhelmed our fridge and freezer space, .
A FB friend is receiving similar assistance from people in her church during her chemo treatment - meals and transportation.
Some years ago I worked for a Christian organization that coordinated the efforts of local churches in meeting community needs. I got a call one day from a NICU nurse who told me that a young woman in our town had given birth to triplets, and needed some help. I had a notice placed in our churches' bulletins--"Baby Holders Wanted!" Believe me, the next day I was swamped with calls! Every grandma in town wanted a piece of that action! Not only did they offer to hold and feed babies, one woman offered to do baby laundry. Another, who had some disabilities, offered to spend time with the toddler-aged sister, so she wouldn't feel neglected.
Awhile before that, the mom in a migrant worker family was bitten by a brown recluse spider and was seriously ill for months. A Christian church took that family under its wing, with meals, housekeeping, whatever.
The churches will step up, and meet needs, when they are known. But, it certainly wasn't the job of the DUmmy's mother's doctor to arrange help for him. It makes me wonder how much effort the DUmmy put into finding help on his own.
