The Christian communities of Syria, Iraq, and Lebanon share a millennia-old heritage and a cultural wealth that transcends borders. Their diversity is reflected in a mosaic of Churches—Maronite, Syriac, Chaldean, and Assyrian—that have profoundly shaped the religious, educational, and social history of the region. However, this shared heritage is now under threat from major systemic challenges. Regional conflicts, forced migrations, and economic crises have led to a massive exodus of Christians, diminishing their demographic presence and undermining their historical role. Despite these challenges, their resilience remains remarkable: in Syria, Churches actively contribute to material and social reconstruction; in Iraq, efforts to revitalise Christian villages are emerging in the Nineveh Plains; in Lebanon, educational and charitable institutions continue to support increasingly vulnerable populations. Yet, these initiatives struggle to keep pace with political upheavals and the disengagement of younger generations. This situation raises a key question: how can these communities preserve their heritage and sustain their role in a changing Middle East, while addressing migration pressures, social fragmentation, and evolving identity challenges?
