Katharina von Bora ran the Luther household at the former Augustinian friary in Wittenberg, a property granted to Luther, as a working estate, a documented economic operation distinct from an ordinary domestic household run for consumption alone. That estate included farmland, livestock, a brewery and a boarding operation housing students and visiting scholars, a documented range of enterprises distinct from a single household task managed on the side.
That operation generated much of the income that supported Luther's work and their six children, a documented financial role distinct from domestic management that contributed nothing to the family's own material support. Luther himself, in letters, called her by the affectionate and half joking title Herr Kate, a documented acknowledgment distinct from an unrecorded or merely assumed authority, recognizing the real practical authority she held over their shared domestic economy.
That the household running the Reformation's own theological center depended financially on an estate one former nun built and managed herself, an operation her own husband named with a title borrowed from male authority, marks Katharina von Bora's role as a documented case where the practical economy sustaining a movement's leading theologian rested on authority his own letters credited to her directly.
