Jacobus de Clusa

Jacob of Juterbogk was a German monk and theologian. Benedict Stolzenhagen, known in religion as Jacob, was born at Jüterbog in Brandenburg of poor peasant stock. He became a Cistercian at the Paradyż Abbey in Poland, and was sent by the abbot to the University of Kraków, where he became master in philosophy and doctor of theology. He returned to his monastery, of which he became abbot. In 1441, however, he was discontented with the absence of strict discipline in his community, he obtained the leave of the papal legate at the council of Basel to transfer himself to the Carthusians, entering the monastery of Salvatorberg near Erfurt, of which he became prior. He lectured on theology at the University of Erfurt, of which he was rector in 1456, and wrote around eighty treatises. Like many men of his time, he promoted Conciliarism, the idea that a general council should be above the pope.
