the original org chart, drawn by priests who put themselves on top.

means A system in which people, things, or ideas are ranked one above another in order of authority, importance, or rank.

from From Greek 'hierarkhia,' joining 'hieros' (sacred, holy) and 'arkhein' (to rule). It first named the ranking of holy beings — the celestial orders of angels stacked from seraphim down — before the word descended to earth to describe any chain of command, sacred or otherwise.
