Nicaea 2025 Symposium: Faith, Council, Legacy

International Symposium | Celebrating the First Ecumenical Council

Join us for this historic gathering as we commemorate the 1700th anniversary of the First Ecumenical Council of Nicaea (325-2025).

This one-day symposium, hosted by the Greek Orthodox Church of the 318 God-bearing Fathers and Thyateira Midlands Ecclesiastical Seminary, features renowned patristics scholar Fr. John Behr alongside distinguished clergy and academics exploring the enduring significance of this pivotal moment in Christian history.

Date: Saturday, 21 June 2025

Time: 10:00am – 5:00pm

Venue: St. Julian’s Church, Shrewsbury, SY1 1UH

Cost: £40 (includes refreshments)

Early Bird Discount: £30 (available until 21 April)

Featured Speaker: Fr. John Behr 

We are honoured to welcome Fr. John Behr, Regius Professor of Humanity at the University of Aberdeen and former Dean of St. Vladimir’s Orthodox Theological Seminary, as our keynote speaker. Fr. John Behr’s definitive works on the formation of early Christian theology—particularly “The Way to Nicaea” and “The Nicene Faith”—have established him as one of Orthodoxy’s leading voices on the First Ecumenical Council. 

His presentation will illuminate how the Holy Fathers at Nicaea articulated and defended the Apostolic Faith concerning the divinity of Christ—the truth that had been handed down from the Apostles themselves. Drawing on his extensive research, including his recent critical edition of “Gregory of Nyssa: On the Human Image of God” (2023), Fr. John Behr will bring profound insights to the conciliar expression of the unchanging Apostolic Tradition that shaped the Nicene Creed we still confess today.
