Chapter 3 traces the tensions and contradictions inherent in attempts to create Jewish homes out of interfaith families, in the Reform movement’s initial responses to the rising interfaith marriage rate. It points to “religion” and “culture” as terms with ever shifting definitions, strategically deployed to permit particular kinds of familial practices. Through sources ranging from 1980 to 2000, Mehta tracks and interprets which Christian practices are labelled as “religious,” and therefore unacceptable, as opposed to “cultural” and therefore permissible. Analytically, the chapter uses practice theory to call into question the underlying assumption of the rhetoric about a Jewish home, which is that it is possible to have a religiously singular home if the parents are from different traditions.
