This paper opens with a discussion of contemporary Franciscan missiology, particularly the notion of mission inter gentes, bringing this into dialogue with recent Christian theological reflection on hospitality. Many missionaries report that they learn about hospitality from the Muslims among whom they live; the presentation attempts to articulate these points of learning and examine whether they are absent, latent, or simply understated in the Christian tradition. In comparative theological perspective, the paper asks not merely what is learned but what type of learning occurs, and how this can shape Franciscan missiology going forward.
