ABSTRACT This article explores how rabbis, directors and members of Amsterdam’s Jewish religious communities view the heritagisation of Jewish religious life by analysing how they interact with Amsterdam’s main synagogues and their collections of ceremonial objects. It focuses on the synagogues of the Jewish Cultural Quarter – the Portuguese Synagogue with its accompanying Sephardi community, and the former Ashkenazi synagogue complex, now the Jewish Museum. From a dynamic heritage perspective, this heterogeneous constellation raises questions about how and why heritage making occurs here. Following a Constructivist Grounded Theory methodology, concurrent data collection and analysis let emerge interrelated conceptual categories that explain how communities interact with these functioning and musealised synagogues and objects: Embodying the transmission of tradition; Instrumentalising the heritage of Jewish religious life; Transforming the beauty of holiness; and Assembling in heritagised synagogues. These categories intersect in the core category of the Jewish religious heritage continuum, which this article presents as a dynamic embodiment of remembering, reconnection, and revival of Jewish tradition. For the interviewees, these performances, and the deployment of functioning and musealised synagogues and collections, form a cultural apparatus that marks their present, diverse and living material culture and grafts a Jewish future onto a Jewish past.
