This paper presents data from interviews with senior Catholic and Buddhist nuns living in the United States who participated in an interreligious dialogue.

Religious traditions develop and exist, these others argue, in relation to one another. Religious con flicts and polemics reformulate and solidify boundaries between traditions. The movement of religious traditions into new contexts reshapes their borders and meanings, and contact and interaction in plural worlds often lead to religious hybridization and other kinds of incorporation (McGuire and Maduro 2005;
