1700th Anniversary: Council of Nicaea
Credo in unum Deum… (I believe in one God…) The Nicene Creed.
In a symbolic pilgrimage of unity, Pope Leo XIV visited Nicaea, recalling the First Council of 325, where bishops gathered to defend the divinity of Christ and craft the Nicene Creed. Standing near the ancient hall where Athanasius once spoke with fiery conviction, the Pope reflected on the Church’s enduring call to safeguard truth.
His visit honored the courage of those early fathers who confronted division with clarity and charity. In prayer, he urged today’s Church to rediscover their bold faith, reminding all that the Creed they forged still binds believers across centuries, cultures, and trials.
Key Attendees of the First Council of Nicaea:
- Emperor Constantine I – convened and presided (not voting).
- Around 300 bishops (traditionally 318), mostly from the Eastern Roman Empire.
- Hosius of Córdoba – Constantine’s theological advisor; likely chaired many sessions.
- Athanasius of Alexandria – then a deacon accompanying Bishop Alexander, a key defender of Christ’s divinity.
- Alexander of Alexandria – leading opponent of Arianism
- Eusebius of Nicomedia – leading supporter of Arius.
- Eusebius of Caesarea – Church historian.
- Arius – brought to defend his teachings, though not a voting member.
Pope Leo XIV visited the site of ancient Nicaea (modern-day İznik, Turkey) on November 28, 2025.
Those Present for Pope Leo XIV’s Visit to Nicaea:
- Pope Leo XIV – making a symbolic pilgrimage of unity.
- Ecumenical Patriarch of Constantinople – welcoming the Pope as a gesture of East–West fraternity.
- Local Bishop of İznik (ancient Nicaea) – host and guide to the historic site.
