“Any attempt at comparing religions as disparate as Catholicism and Islam is praiseworthy but difficult. . . .

By pointing out similar theologies, polity, sacred intercessors, martyrdoms, and mysticism of these two faiths, the authors help us understand a much-misunderstood religion.” — Library Journal

“At once probing, sympathetic, learned, and insightful. . . . Stands alone in its comprehensive, systematic, and nuanced treatment of each tradition. . . .

A trustworthy and timely work that will reward frequent use by anyone interested in the shape and future of religion in the modern world.” — Middle East Insight
