This volume brings together the writings of Dr. Aref Ali Nayed, one of the Muslim world’s leading theologians, tracing his engagement and dialogue with the Catholic Church and with Catholic scholarship. He lived for many years in Rome, where he studied Catholic theology and taught Islamic theology. For the last two decades, he has been one of the most articulate Muslim interlocutors with the Catholic tradition and a leading Muslim exponent of contemporary interfaith dialogue. This volume includes his famous critique of Pope Benedict XVI’s Regensburg lecture and the subsequent debate and engagement with Catholic scholars on a range of theological and inter-faith issues. Dr. Nayed’s writings are characterized by a profound respect for all people of faith along with a deep reverence for his own faith and the rich scholarly traditions of Islam and reflect an acute awareness of the modern world and its intellectual currents.
