In a world of growing religious plurality, the question of mutual understanding between Islam and Christianity is no longer merely academic, but also existential. This study offers a renewed approach to interreligious dialogue by engaging the Qur’an not as a distant or problematic text, but as a meaningful partner in theological reflection. Eastern Catholic theology offers some vistas that have not been explored before, and it is precisely within this horizon that the present study is situated. Rooted in the Catholic tradition and informed by an Eastern Christian perspective, the author emphasizes the importance of a faithful and responsible engagement that remains open to encounter with the religious other. The Qur’an is presented here as a hermeneutical mirror—one that challenges, deepens, and expands Christian self-understanding. In a context marked by both religious diversity and geopolitical tension, this work invites readers to reconsider the boundaries of revelation, the role of tradition, and the activity of the Holy Spirit beyond the visible limits of the Church.
