Martin Luther needed a word that could make sweeping a kitchen floor as sacred as saying a prayer.
The German word Beruf means occupation, profession, or job. Ask a German Was sind Sie von Beruf? and they will tell you what they do for a living.1 The question sounds routine. Its history is not.
In his 1520s translation of the Bible, Martin Luther used Beruf in a passage from the Book of Sirach to express the idea of a divine calling.2 Before Luther, the concept of vocation, from the Latin vocatio, was reserved for priests and monks. Ordinary labor had no sacred dimension. Luther's radical claim was that every legitimate form of work, from farming to carpentry to household duties, could be a calling from God.
Max Weber, the German sociologist, identified this linguistic shift as one of the most consequential outcomes of the Reformation. In The Protestant Ethic and the Spirit of Capitalism, published in 1905, Weber wrote that the word Beruf carried a religious conception, "that of a task set by God," that had no equivalent in Catholic or classical languages.3
Weber argued that Protestant theology, particularly Calvinism, transformed work from a necessary burden into a moral duty, and that this transformation laid the cultural groundwork for modern capitalism.4
The word Beruf today has largely lost its theological weight. A German answering the question hears "occupation," not "divine summons." The English word "calling," its closest translation, has undergone a similar secularization.5 Gustaf Wingren, a Swedish theologian, published Luther on Vocation in 1957, documenting how Luther expanded Beruf to include biological roles (father, mother), social positions (master, servant), and community functions (officeholder, volunteer).6
The gap between Beruf and "job" mirrors the distance between a culture that embedded spiritual meaning in daily labor and one that treats employment as a contractual transaction. The word itself is a fossil of the moment when that meaning was still alive.7
