One sister, and her baptist in-laws, have started praying the rosary during the severe illness of some of them, and I am helping enthusiastically with that–providing rosaries and scriptural rosary guides, and giving her help in what to say and what not to say to them. she is on her way back, more because of the rosary than because of me.
