This monumental book outlines, clarifies, and defends official Roman Catholic teaching on the relationship between Christianity and other religious traditions in the light of Catholic belief that "We must hold that the Holy Spirit offers to all the possibility of being made partners, in a way known to God, in the paschal mystery."
(Gaudium et Spes, 22).
Part I studies the history of these issues. Part II examines their theological framing. Part III deals with Christianity and the religions since Vatican II. Part IV deals with Judaism, Confucianism, Hinduism, and Islam as they see themselves in relation to Christianity. A final chapter by Michael Fitzgerald is a theological reflection on the foundations of interreligious dialogue.
