Unfortunately a religion that's only about works and recruitment as the main work this is what happens. People live thier lives in the cult and give their all but when they can finally do no more do to age or sickness they are forgotten.
My father was a good guy finally became an elder and was the elder most would go to with their problems but he got booted do to political crap in the elder body. He later had to move because of his health. When he died only a handful of people from his hall even showed up for his funeral, hell my nieghbor's who only knew him from when he came over to my house showed up!!!
Again this religion uses people up and kicks them to the curb when they can't perform anymore.
