Across historical periods-from ancient temple theodicies to early Christian-Muslim cooperation in the Umayyad world-the concept of loyalty can be considered both a stabilizing force and a site of contestation. This richly textured volume brings together Christian and Muslim scholars to explore loyalty as a complex, morally charged notion within interrelated religious and philosophical traditions. Drawing on textual, historical, philosophical, and ethnographic approaches, separate chapters variously trace the nuances of loyalty's evolution from scriptural foundations to contemporary ethical crises. Scholars of Islam examine Qur'anic and Sufi articulations of covenant, fidelity, and walā', highlighting tensions between loyalty to God, community, and the moral self. Contributions from the Christian tradition, meanwhile, explore fraternity, kenosis, ecclesial allegiance, and political loyalty, negotiating communal belonging against conscience and self-emptying love. Collectively, these pieces argue that loyalty becomes virtuous only when critically examined and subordinated to higher moral ends: God, justice, and human flourishing.
