St. Cyril of Alexandria offers us here the clearest Biblical understanding of the Orthodox Priesthood on the basis of a Christian exposition of the Old Testament Priesthood. The general principle that Christ did not come to destroy the Law, but to fulfill, holds true for the Priesthood of the Law as well. St. Cyril explains how the Priesthood of the Law is fulfilled and renewed in the Christian Priesthood. His exposition offers Orthodox clergy a profound explanation of what they stand for and highlights many aspects of their sacred ministry.
