Mormonism and scientology both have castes, albeit in varying forms of "ranking". A person of a lower rank is always subservient to the higher ranked version, which is castes.

There may be a degree of mobility between ranks, but mormonism at least makes it explicit that a black person for instance starts at a subservient rank, and can never reach the top rank, as that is reserved for white people.

Your position in a job, or the availability of that job, or housing, or in fact anything, should never be restricted simply due to some religious doctrine.
