I don't think "under the care of" has anything to do with discipline.
Look at certificates to go to another meeting
These are Friends recommending their Friend The following phrase is from a certificate I copied to my records this morning:
"..we recommend him to your religious care with desire for his welfare everyway..."
Another example: "nothing appearing to prevent her request being granted, we rocommend her to your Christian care with desires for her welfare every way."
