Grand Master

A west Calophesian religious rank, directly below an Ecclesian by virtue of commanding a clerical order . A Grand Master is of equivalent rank to an Archpriest (the head of a basilica) and a High Priest (the head of a temple).
Because of the size of many clerical orders, the rank of 'Master' is often bestowed to senior clerics to whom certain responsibilities a delegated. 
The specific title given to a person of this rank can also depend on the denomination they belong to, although they are all commonly referred to as 'Grand Master'.
