Many Protestants believe that in likening the whole body of believers to the priesthood of ancient Israel, it removes the possibility of a spiritual aristocracy or hierarchy within Christianity. God is equally accessible to all the faithful; no Christians have been set above others in matters of faith or worship. In this, it meshes with texts that say that God is no respecter of persons, and in Him there is neither Hebrew nor Greek, slave nor free, male nor female. (Galatians III:28) The doctrine of the priesthood of all believers is one of the sources of the powerful Western social and political ideal of human equality.
Eastern Orthodox Christians traditionally believe that this passage gives responsibility to all believers for the preservation and propagation of the Gospel and the Church. They affirm both the priesthood of all believers (often called "the faithful") and the ordained priesthood, or office of presbyter, while observing that the vast majority of Protestants also draw some distinction between their own ordained ministers and lay people.
