Abstract: Despite growing insights into the secular practices of former socialist states, we are yet to grasp fully their resonance in religious lives. Taking socialist modernity and Old Belief as distinct ethical projects, in this article I discuss the ethical engagements of Russian Old Believers in socialist Romania as reflected in individual biographies. Their struggle to maintain an ascetic Orthodox culture in the midst of an intrusive atheist state was at odds with the urge to join a modernizing project that preached the collective good. This tension was managed through a temporary ‘secularization’ which allowed for differentiated generational commitments and the successful reproduction of their tradition within the socialist system. Old Believers’ return to the church in old age reveals their attempt to shape their lives through ethical action based on the obligation to continuity, to carry on the old faith. It shows how the pursuit of continuity in the Old Belief is a virtuous practice leading to moral exemplarity in a space of equivocal moralities.
