Consecration of a bishop is the process during which a candidate for the episcopate receives the fulness of the grace of the priesthood through the Sacred Mystery of ordination by the laying of hands (in the Greek: Cheirotonia) in succession from the Holy Apostles. The office of bishop is the highest clerical rank in the Orthodox Church. While some bishops may receive titles such as Patriarch, Metropolitan, or Archbishop, all bishops are equal and the titles are administrative ranks and marks of dignity and honor. At his consecration, a bishop receives grace not only to perform the Sacred Mysteries but also to bestow the grace of ordination on others.
