Harper’s has a fascinating piece on Nicholas of Kues (= Cusa, I think), or Cusanus, a fifteenth-century Roman Catholic cardinal who sought common ground between Christianity, Judaism, Islam, and even Hinduism in the wake of the Ottoman Turks’ conquest of Constantinople, when most of European Christendom was girding for the Crusades. I’d never heard of Cusanus before, but apparently he’s considered a leading theologian of the Renaissance in Continental Europe. And his perspective sounds like it would be invaluable for people of faith in the twenty-first century:
What Cusanus therefore proposes is tolerance. However, it is not the insulting sort of tolerance, which proposes official indifference. Rather it is a tolerance that has its roots in a philosophical commitment to the search for truth and a recognition that human frailties and imperfections will always lead to mistakes. “For it is a condition of the earthly human estate to mistake for truth that which is merely long-adhered-to custom, indeed, even to mistake this for a part of nature,” Cusanus writes (habet autem hoc humana terrena condicio quod longa consuetudo, quæ in naturam transisse accipitur, pro veritate defenditur.)
