Abstract
In a context of pluralism, this article reinterprets ecclesial unity beyond uniformity, proposing hospitality as a fundamental theological category. Through a hermeneutical analysis of patristic sources (Ignatius of Antioch, Irenaeus of Lyon, and Augustine of Hippo) and their dialogue with contemporary theologians of pluralism, communion is articulated as a dynamic of mutual welcome grounded in trinitarian life. The research concludes that Christian unity in the present age must be sustained as a practice of trinitarian hospitality, where diversity is not merely tolerated, but celebrated as a gift. Thus, ecclesiology is revealed not as a system of power, but as an ethic of openness in which identity is transformed into service and truth is communicated through the recognition of otherness.
