Against the background of the Catholic Church’s global organizations and activities in interreligious dialogue, this book focuses on recent Roman Catholic engagement with other religious traditions in the United States, and the significance of this experience of religious pluralism for Christian theology. The work surveys the changes in the demographic, social, cultural, and religious landscape in the United States over the last half-century, and the ways in which Christians in this setting relate to the traditional religions of Africa and Latin America, and to the Jewish, Muslim, Hindu, and Buddhist traditions.
