This paper examines contemporary ascetic performance in the Orthodox Christian monasteries of Mount Athos, Greece. Drawing on fourteen months of ethnographic fieldwork, it analyzes how forms of ascetic withdrawal and discipline are exercised in, and shaped by, the spiritual, political, and economic networks that connect Mount Athos to the ‘world’ beyond its border. It argues that contemporary forms of Christian ascetic detachment and soteriology constitute a moral, social, and material boundary regime that shapes how monks order their lives, make decisions about themselves and their community, and embrace or reject connections to others. By reflecting specifically on the interactions of Athonite monks with pilgrims, men and women in parishes, and wage-workers, it illustrates the effects of contemporary asceticism on the lives of individuals living at different degrees of distance from the community. The paper offers insights about how asceticism intersects with contemporary social forces, global discourses, and diverse human experiences.
