Pope Leo XIV joined Ecumenical Patriarch Bartholomew I and Christian leaders on Friday at the shores of Lake Iznik in Turkey, the site of the A.D. 325 Council of Nicaea, to mark the council’s anniversary and pray for Christian unity. The gathering recited the Nicene Creed over the exposed stone foundations of an ancient basilica, in an event the pope described as central to his first foreign trip and ecumenical mission. Leaders from Catholic, Orthodox, Protestant and other historic churches participated, framing the commemoration as both a remembrance and a call to overcome centuries-old divisions.
Key Takeaways
- Pope Leo XIV and Ecumenical Patriarch Bartholomew I led a joint prayer service on Friday at Iznik, Turkey, the site of the 325 Council of Nicaea.
- Participants recited the Nicene Creed, the creed born at Nicaea and still widely used across Catholic, Orthodox and historic Protestant churches.
- The lakeside ceremony took place at excavations of the Basilica of Saint Neophytos, whose stone foundations were recently revealed as Lake Iznik’s waters fell.
- Attendees included priests, patriarchs and bishops from Greek, Syrian, Coptic, Malankarese, Armenian, Protestant and Anglican communities.
- About 20 members of the New Welfare Party staged a short protest before the service; police kept a heavy presence and the demonstration dispersed peacefully.
- The visit highlighted Turkey’s small Catholic population—around 33,000 in a country of 85 million, according to Vatican statistics—and the church’s pastoral role with migrants and refugees.
- The prayer was the centerpiece of the pope’s trip to Turkey; he plans further ecumenical meetings, a visit to the Blue Mosque, a Mass at Istanbul’s Volkswagen Arena, and departure to Lebanon on Sunday.
Background
The Council of Nicaea convened in A.D. 325 under Emperor Constantine and produced the Nicene Creed, a statement of faith that remains a foundational text for many Christian traditions. At the time the Roman Empire was emerging from civil conflict, and Constantine’s favor toward Christianity helped create the political conditions for a pan-imperial council. The creed sought to clarify theological points that were then contested and to establish a common formula for worship and doctrine.
Christianity remained united for several centuries after Nicaea but formally split between East and West in the Great Schism of 1054, a rupture driven largely by disputes over papal primacy and theological-political differences. Despite that division, the Nicene Creed is accepted across Catholic, Orthodox and most historic Protestant churches, making it a rare locus of shared heritage. In modern times, ecumenical efforts have sought to bridge other doctrinal and institutional gaps while acknowledging historical grievances.
Main Event
The commemorative service unfolded beside the excavated remains of the Basilica of Saint Neophytos on Lake Iznik, where priests alternated Catholic and Orthodox hymns and the gathered leaders recited the Nicene Creed aloud. Pope Leo XIV described the creed as ‘of fundamental importance in the journey that Christians are making toward full communion,’ urging participants to reject divisions and to pursue fraternal dialogue.
Ecumenical Patriarch Bartholomew I framed the gathering as a living return to the sources of Christian faith, saying the creed ‘acts like a seed for the whole of our Christian existence’ and calling the assembly a commitment to move forward together rather than merely commemorate the past. Representatives from diverse Christian traditions—Greek Orthodox, Syrian, Coptic, Malankarese, Armenian, Protestant and Anglican—stood together over the ancient foundations.
The pope used the occasion to condemn religion’s use to justify violence or extremism and to call for ‘fraternal encounter, dialogue and cooperation.’ The service was the high point of his visit to Turkey and the primary purpose of the trip, his first foreign journey as pontiff. Local responses ranged from warm hospitality—Catholics welcomed the pope at the Cathedral of the Holy Spirit—to unease among a small number of nationalists who staged a peaceful protest ahead of the ceremony.
Analysis & Implications
The joint prayer at Iznik is symbolically potent: it places contemporary ecumenical diplomacy at the historical wellspring of a creed accepted across traditions. By reconvening church leaders at Nicaea’s site, the event reinforces shared doctrinal ground while acknowledging institutional separations that have persisted since 1054. This gesture does not resolve institutional differences, but it strengthens moral and spiritual ties that can underpin further theological dialogue.
Politically, the gathering navigated sensitive terrain in Turkey, a predominantly Sunni Muslim nation where Christians form a small minority. The presence of high-profile Christian leaders risks being interpreted by some as a challenge to national identity, as illustrated by the small protest; at the same time, Turkish authorities facilitated the event, suggesting an official willingness to host major interfaith and heritage-focused encounters. Such diplomacy may serve soft-power aims for both the Holy See and Ankara.
For the Catholic community in Turkey—about 33,000 people—the pope’s visit provides visibility and pastoral encouragement, particularly regarding ministry to migrants and refugees referenced by the pontiff. For Orthodox–Catholic relations, public, joint liturgical gestures and shared readings of foundational creeds can deepen mutual trust and create practical pathways for cooperation on social issues, even if full institutional reunion remains remote.
Comparison & Data
| Item | Figure / Date |
|---|---|
| Council of Nicaea | A.D. 325 (approx. 1,700 years ago) |
| Turkey population | ~85,000,000 |
| Catholics in Turkey | ~33,000 (Vatican statistics) |
The table highlights the scale differences between a global historical milestone and present-day minority communities in Turkey. The contrast underscores why symbolic acts at heritage sites can have outsized resonance compared with routine pastoral activity: they connect contemporary communities to formative moments in Christian history while occurring amid a very different religious and political landscape.
Reactions & Quotes
‘The Nicene Creed acts like a seed for the whole of our Christian existence.’
Ecumenical Patriarch Bartholomew I
Bartholomew used this remark to stress continuity between the fathers of Nicaea and present-day ecumenical efforts, framing the commemoration as active witness rather than mere nostalgia.
‘We are all invited to overcome the scandal of the divisions that unfortunately still exist and to nurture the desire for unity.’
Pope Leo XIV
The pope tied theological unity to practical commitments against violence and fundamentalism, urging dialogue and cooperation among Christians and warning against religion being used to justify conflict.
‘He was so simple. We just felt he was at home.’
Sister Margret, Little Sisters of the Poor (Istanbul)
Sister Margret’s comment reflected the personal reception the pope received during pastoral visits that accompanied the commemorative service.
Unconfirmed
- The protestors’ claim that the meeting aimed to establish a ‘Vatican-like Greek Orthodox state’ in Turkey is an allegation voiced by a small group and lacks corroborating evidence.
- The precise archaeological identification linking the exposed stone foundations directly to the original church that hosted the 325 council is described in local reports but may require further scholarly confirmation.
Bottom Line
The Iznik commemorative prayer brought senior Christian leaders together at a formative historical site, reinforcing shared doctrinal ground while signaling an ongoing, cautious pursuit of reconciliation. Symbolic acts such as this do not erase institutional divides, but they can create moral momentum and public goodwill that support further theological and pastoral conversations.
In Turkey’s charged political environment, the event balanced hospitality and security, and it offered visible encouragement to a small Catholic community and to Christians of many traditions. Observers should watch whether this gesture leads to sustained joint initiatives on social issues, migration or interchurch dialogue, and whether it affects Turkey’s domestic debates about religion, heritage and national identity.
