Two very different churchmen, Riccoldo da Montecroce and Nicholas of Cusa, though separated by time and place, were affected by a similar catastrophe: the fall of a Christian capital to Muslim forces. Both responded by seeking heaven’s help to end interreligious strife, but Riccoldo wrote letters full of questions to the church triumphant, while Nicholas envisioned a celestial interfaith council that solved the problem. Their disparate responses exemplify the diversity of medieval perspectives on religious plurality.
