Priesthood of all believers

The priesthood of all believers or universal priesthood is a biblical principle in Protestant branches of Christianity which is distinct from the institution of the ministerial priesthood (holy orders) found in some other branches, including the Roman Catholic and Eastern Orthodox. Derived from the Bible and elaborated in the theology of Martin Luther and John Calvin, the principle became prominent as a tenet of Protestant Christian doctrine, though the exact meaning of the belief and its implications vary widely among denominations. The Odes of Solomon has an early understanding of a view of the priesthood of all believers, suggesting that Jewish-Christians in the region of Antioch believed themselves to be priests of God making spiritual sacrifices. Tertullian held a belief like the priesthood of all believers, however his views on the laity were influenced by Montanism. As the Montanists believed in the priesthood of every believer. Irenaeus has been argued to have held to a view of universal priesthood because he stated "for all the righteous possess the sacerdotal rank". The universal priesthood of all believers is a foundational concept of Protestantism. While Martin Luther did not use the exact phrase "priesthood of all believers", he adduces a general priesthood in Christendom in his 1520 To the Christian Nobility of the German Nation in order to dismiss the medieval view that Christians in the present life were to be divided into two classes: "spiritual" and "secular". He put forward the doctrine that all baptized Christians are "priests" and "spiritual" in the sight of God: That the pope or bishop anoints, makes tonsures, ordains, consecrates, or dresses differently from the laity, may make a hypocrite or an idolatrous oil-painted icon, but it in no way makes a Christian or spiritual human being. In fact, we are all consecrated priests through Baptism, as St. Peter in 1 Peter 2[:9] says, "You are a royal priesthood and a priestly kingdom," and Revelation [5:10], "Through your blood you have made us into priests and kings.
