While Catholics in Germany engage in endless naval gazing in an attempt to justify dismantling their own credibility, an ancient Catholic community that has survived persecution, war and the horrors of ISIS is fighting for something much more fundamental: its continued existence in the land where Christianity first took root. There's been an extraordinary gathering in Rome which really deserves our attention. The bishops of the Chaldean Catholic Church met from 16–19 October under their new Patriarch, Mar Polis III Nona, to consider the future of one of Christianity's oldest surviving communities. Their final statement addresses everything from priestly formation and liturgical renewal to the preservation of Christian identity among the enormous diaspora created by decades of violence and instability in Iraq. The Chaldean Church is in full communion with Rome, but possesses its own ancient Eastern liturgical and ecclesiastical traditions. Its spiritual inheritance reaches back to the Christianity of Mesopotamia and its liturgy preserves Syriac, a form of Aramaic closely related to the language spoken by Our Lord. Consider what this community has endured. Following the invasion of Iraq in 2003, Christians faced successive waves of intimidation, kidnappings, church bombings and murder. The rise of ISIS brought further devastation, with Christian families driven from Mosul and the Nineveh Plain, often abandoning homes and communities that had existed for centuries. The consequences have been catastrophic. Iraq's Christian population, once estimated at more than 1.5 million, has fallen dramatically. Many of those who fled have rebuilt their lives in Europe, Australia and North America, leaving the Church confronting an agonising question: how do you preserve an ancient Christian civilisation when so many of its people can no longer safely live in their ancestral homeland? This is what makes the Chaldean Synod's deliberations so interesting. The bishops have committed themselves to strengthening priestly formation, reviewing their ecclesiastical regulations and developing a Liturgical Directory intended to preserve the sacredness, fidelity and beauty of their worship. WOW! That last point particularly caught my attention! Here is a Church that has experienced persecution, displacement and demographic collapse, yet its bishops recognise that preserving the integrity of their inherited liturgical tradition is essential to the future of their communities. What a contrast with Traditiones custodes! Their approach is not simply about maintaining an attractive cultural inheritance. The liturgy is where successive generations discover themselves to be members of a Church whose identity transcends national boundaries and political upheaval. There is surely a lesson here for those of us in the West. From the way some prelates speak, you would think liturgical tradition were an optional aesthetic preference, something to be adjusted according to contemporary pastoral fashions. For communities such as the Chaldeans, the connection between worship, faith and identity is considerably more immediate. Their traditions have helped sustain them through circumstances most Western Catholics can scarcely imagine. But the Synod also recognises that preserving the past is not sufficient and so it calls for better formation, stronger pastoral care, support for families and young people and practical solidarity between prosperous communities abroad and those struggling to survive in Iraq. There is a tension here which deserves serious consideration. The diaspora provides financial support, political advocacy and opportunities for families who might otherwise face an uncertain future. But every generation that establishes itself permanently overseas also makes the restoration of a substantial Christian presence in Iraq more difficult. Patriarch Nona knows something of this personally, as Archbishop of Mosul, he was forced into exile when ISIS seized the city in 2014. He subsequently served the Chaldean community in Australia before being elected Patriarch earlier this year. Perhaps the most moving aspect of the gathering was the celebration of the Chaldean Divine Liturgy in St Peter's Basilica on 15 October, bringing the prayers and sacred chants of this ancient Eastern Church into the very heart of Catholicism. It was also a powerful reminder that Catholic unity does not require liturgical uniformity irrespective of what Pope Francis and Cardinal Roche have attempted to assert to the contrary. The Church's communion embraces distinct and venerable traditions, each contributing something precious to the whole. We devote enormous attention to the internal controversies of Western Catholicism, but perhaps we should spend more time listening to Christians whose immediate concerns are preserving their faith, their families, their liturgy and their very presence in the lands of the Apostles. Their survival is not merely a matter of cultural preservation, it's a question of whether Christianity will continue to possess a living, worshipping presence in places where the Gospel has been proclaimed for nearly two thousand years.
