This Dispatch examines how religious symbolism and anti-migrant mobilization converged in Poland in mid-2025 to perform a sanctified politics of protection. Focusing on Catholic sermons, protests, and citizen border patrols, it shows how exclusion is recast as moral duty and care. Drawing on publicly circulated materials, the analysis develops the concept of affective legitimacy to capture moments when moral rightfulness is enacted through emotion, ritual, and ethical vocabularies as institutional trust wanes. The Polish case is treated as a diagnostic vignette of an emergent repertoire in which protection is felt rather than procedurally justified, highlighting how democratic authority can be reconfigured through affective publics rather than liberal-democratic accountability.
