In this stimulating dialogue these two great men, who stand on opposite sides of the church door, discuss some of the most controversial issues of the day.

One is a respected scholar and one of the preeminent ecumenical churchmen of Europe; the other the world-famous author of The Name of the Rose, a scholar, philosopher and self-declared secularist, a man who writes with equal ease about Thomas Aquinas and James Joyce, computers and the medieval Templars.

Often adversarial but always amicable, their debate will fascinate many.
