[This talk makes reference to a handout which you can find at https://www.stpauls.co.uk/sites/default/files/2025-10/Ludlow%20Nicaea%20handout.pdf] 2025 marks 1,700 years since the formation of the Creed of Nicaea, and around the world many Christian churches from many different denominations are marking the anniversary. But what is so important about it and why do we still say it so many years on? Morwenna Ludlow gives a very brief history of how the Creed of Nicaea came to be, what it sought to address, and how it relates to other creeds and early statements of faith. Morwenna Ludlow is Professor of Christian History and Theology at the University of Exeter, and holds an honorary position as Canon Theologian at Exeter Cathedral. Her particular interest is on the early church and the reception of early theology by modern thinkers, alongside implications for the world today.
