Book excerpt: Nicholas of Cusa (1401-1464) was active during the Renaissance, developing adventurous ideas even while serving as a churchman. The religious issues with which he engaged – spiritual, apocalyptic and institutional – were to play out in the Reformation. These essays reflect the interests of Cusanus but also those of Gerald Christianson, who has studied church history, the Renaissance and the Reformation. The book places Nicholas into his times but also looks at his later reception. The first part addresses institutional issues, including Schism, conciliarism, indulgences and the possibility of dialogue with Muslims. The second treats theological and philosophical themes, including nominalism, time, faith, religious metaphor, and prediction of the end times.
