Interreligious Concordance and Christianity in Nicholas of Cusa’s De Pace Fidei

In the months following the Turkish capture of Constantinople in 1453, Nicholas of Cusa composed his De Pace Fidei, a text with which he defended and highlighted the value of interreligious dialogue and peace. Beginning with a textual analysis of its central formula (“una religio in rituum varietate”), I analyze the role that Christianity occupies in the text: I exclude its possible reduction to the una religio or to one of the multiple world religions. I then identify through a literal analysis its role as a mediator between the plurality of historical religions and that religio founded on the fides orthodoxa on which the cardinal rests his argument. In addressing this matter, I also establish how the German cardinal makes the heavenly representatives of Christianity consciously use philosophical and not only theological arguments to avoid the reduction of his position to any kind of historical one. I, hence, argue for the possible transposition of the De Pace Fidei’s method to a contemporary philosophy of interreligious dialogue.
