Mandaeism
[T]hose amongst the community who possess secret knowledge are called Nauraiia - Naoreans (or, if the heavy '' is written as 'z', Nazorenes).  At the same time the ignorant or semi-ignorant laity are called 'Mandaeans', Mandaiia - 'gnostics'.  When a man becomes a priest he leaves 'Mandaeanism' and enters tarmiduta, 'priesthood'.  Even then he has not attained to true enlightenment, for this, called 'Nairuta', is reserved for a very few.  Those possessed of its secrets may call themselves Naoreans, and 'Naorean' today indicates not only one who observes strictly all rules of ritual purity, but one who understands the secret doctrine.
