The following excerpt is taken from An Open Letter to the Christian Nobility by Martin Luther. Although it is directed toward the Church in Rome circa 1520, its truth applies to any church at any time that advocates for a sacred-secular vocational divide.
It is pure invention [fiction] that pope, bishops, priests, and monks are called the “spiritual estate” while princes, lords, artisans, and farmers are called the “temporal estate.” This is indeed a piece of deceit and hypocrisy. Yet no one need be intimated by it, and for this reason: all Christians are truly of the “spiritual estate,” and there is no difference among them except that of office. Paul says in 1 Corinthians 12:12-13 that we are all one body, yet every member has its own work by which it serves the others. This is because we all have one baptism, one gospel, one faith, and are all Christians alike; for baptism, gospel, and faith alone make us spiritual and a Christian people.
The pope or bishop anoints, shaves heads, ordains, consecrates, and prescribes garb different from that of the laity, but he can never make a man into a Christian or into a spiritual man by so doing. He might well make a man into a hypocrite or a humbug and blockhead, but never a Christian or a spiritual man. As far as that goes, we are all consecrated priests through baptism, as St. Peter says in 1 Peter 2:9, “You are a royal priesthood and a priestly realm.” The Apocalypse says, “Thou hast made us to be priests and kings by thy blood” (Rev. 5:9-10). . . .
Priest as Officeholder
Since those who exercise secular authority have been baptized with the same baptism, and have the same faith and the same gospel as the rest of us, we must admit that they are priests and bishops and we must regard their office as one that has a proper and useful place in the Christian community. For wh
oever comes out of the water of baptism can boast that he is already a consecrated priest, bishop, and pope, although of course it is not seemly that just anybody should exercise such office.
Because we are all priests of equal standing, no one must push himself forward and take it upon himself, without our consent and election, to do that for which we all have equal authority. For no one dare take upon himself what is common to all without the authority and consent of the community. And should it happen that a person chosen for such office were deposed for abuse of trust, he would then be exactly what he was before. Therefore, a priest in Christendom is nothing else but an officeholder. As long as he holds office, he takes precedence; where he is deposed, he is a peasant or a townsman like anybody else. . .
No Distinction in Status
It follows from this argument that there is no true, basic difference between laymen and priests, princes and bishops, between religious and secular, except for the sake of office and work, but not for the sake of status. They are all of the spiritual estate, all are truly priests, bishops, and popes, but they do not all have the same work to do. Just as all priests and monks do not have the same work. This is the teaching of St. Paul in Romans 12:4-5 and 1 Corinthians 12:12 and in 1 Peter 2:9, as I have said above, namely, that we are all one body of Christ the Head, and all members one of another. Christ does not have two different bodies, one temporal, the other spiritual. There is but one Head and one body.
Therefore, just as those who are now called “spiritual,” that is, priests, bishops, or popes, are neither different from other Christians nor superior to them, except that they are charged with the administration of the Word of God and the sacraments, which is their work and office, so it is with the temporal authorities. They bear the sword and the rod in their hand to punish the wicked and protect the good. A cobbler, a smith, a peasant—each has the work and office of his trade, and yet they are all alike consecrated priests and bishops. Further, everyone must benefit and serve every other by means of his own work or office so that, in this way, many kinds of work may be done for the bodily and spiritual welfare of the community, just as all the members of the body serve one another (1 Cor. 12:14-26).
