Johann von Staupitz was a German theologian and priest who served as the Vicar General of the Augustinian friars. Born around 1460, he held significant academic and religious positions, including serving as a dean at the University of Wittenberg and later as the Abbot of the Benedictine Abbey Sankt Peter in Salzburg. He is most famously recognized for his spiritual mentorship of Martin Luther, providing theological guidance that helped the future reformer navigate intense periods of spiritual doubt and inadequacy.
