This article engages the condition of religious apathy in western secular society, drawing on the apparent pessimism of secularization as a creative catalyst for re-imagining the scope of public mission. It first highlights the reality of religious apathy as observed sociologically, and briefly surveys varied missiological responses to western church decline. An alternative response, ‘Radical Inculturated Proclamation’ is then offered, embodying the inherently paradoxical nature of the Gospel as both drastically distinct and culturally embedded within the religiously apathetic western context. This concept is further explored with a nuanced reflection on the intentionally ‘absurd’ idea of self-aware street preaching and the possible implications for creative interruption of contemporary public spaces. Incorporating the perceived inappropriateness of such practices is deliberate, enabling active embodiment of the Gospel’s inculturated radicality within a public sphere with no apparent ears to hear. Such a proposal contributes to public theological engagement by reconstructing the cultural and theological limitations of contemporary kerygmatic expression within a post-Christendom context.
