Lecture Marks 1,700 Years Since the Council of Nicaea
Saturday, 26th July 2025 ∙ 1pm ∙ St Patrick’s Deanery (Kevin Street, Dublin)

The Council of Nicaea, in 325 AD, was the first ecumenical council in the history of the Christian Church. The meeting of bishops and church leaders at the direction of Emperor Constantine the Great resulted in the affirmation of the Holy Trinity and the formation of what would be known as the Nicaean Creed, which has been affirmed by Christians worldwide for 1,700 years.
On Saturday, July 26, Dr Dafydd Mills Daniel, Lecturer in Divinity in the University of St Andrews and regular contributor to BBC Radio 4, will deliver a talk entitled ‘Heresy! The Nicene Creed and the Invention of Orthodoxy’ on the legacy of this pivotal event in the history of the Christian Church. Contributions and responses from Dr janet Rutherford and Dr Alexander O’Hara will follow the key lecture, concluding with a reception of tea, coffee, and refreshments.
This event will be held in The Deanery, Kevin Street. It is free of charge to attend, but please RSVP by next Thursday afternoon (July 24) through the link provided as follows: https://www.stpatrickscathedral.ie/event/lecture-marking-1700-years-of-the-council-of-nicaea
