This paper explores the following question: How does individual religiosity and attachment to a religious community relate to sectarian political loyalties or interpersonal prejudices in a post-conflict, institutionally sectarianized society? The paper explores this question through dialectic, participatory methods with youth involved in community-based youth associations with a religious component. The paper investigates how religiously devout youth in Lebanon conceptualize the personal and communal elements of their religiosity in relation to sectarian politics. In this way, the paper contributes to a study of social sectarianism, in which scholars are striving to understand what individuals mean when they speak about sect, and how discussions surrounding sect mask more complex underlying social realities. Overall, these accounts suggest that personal and social religiosity both positively influence anti-sectarian political outlook among participants, while other factors, such as the institutional sectarianization of public life and a history of violent conflict maintain participants' default attachment to co-sectarian networks in terms of routine, economic security, and communal belonging.
