“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. …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.”

Martin Luther, To the Christian Nobility, LW 44:127-130.
