Theological Orthodoxy and the Ecumenical Journey: Learning from the Council of Nicaea
Communiqué of the Porvoo Theological Conference, Cardiff, October 7–9 2025

Every year, the Porvoo Communion arranges a conference in October for the member churches around a particular theme. In 2025, in celebration of the 1700th anniversary of the Council of Nicaea, the Communion held its triennial theological conference in Cardiff on the theme: Theological Orthodoxy and the Ecumenical Journey: Learning from the Council of Nicaea, generously hosted by the Church in Wales.
At the Opening Eucharist, the Evangelical Lutheran Church in the Faroe Islands signed the Porvoo Declaration and was welcomed with great joy as a new member of the Porvoo Communion. This was a significant highlight of this year’s conference, and was attended by the Bench of Bishops of the Church in Wales alongside the participants from the Porvoo churches attending the Conference. The Bishops also hosted a special reception with invited guests from denominations and organisations involved in Welsh ecumenical life, where Welsh culture was celebrated with music from a traditional ‘plygain1’ service.
During the Conference, the participants worshipped together and visited several places of interest in Cardiff and experienced some of the Welsh context. The importance of the bilingual environment was highlighted by a visit to the Senedd (parliament) where a copy of Bishop Morgan’s 1588 Welsh Bible was on display, widely credited with helping to preserve the Welsh language by making Scripture accessible to Welsh speakers. The strength of diversity was underpinned by taking part in Ecumenical Vespers in the Roman Catholic Cathedral on the eve of the Feast of St John Henry Newman, where the Rt Revd Dr Rowan Williams was invited to give the reflection, and by meeting in a venue operated by the Roman Catholic Church.
Professor Catrin Haf Williams and Bishop Rowan Williams delivered the two keynote addresses entitled ‘Investigating the Origins and Shape of Early Divine Christology’ and ‘Nicaea, the New Creation, and the Body of Christ’, respectively.
Shorter presentations were given by various participants during the three conference and discussion sessions which examined historical and contemporary perspectives on the
Council and its Creed:
– The Council of Nicaea: Inscribing the bounds of Christological Orthodoxy
– Beyond Nicaea: The Christ of the Councils as the guarantor of Christian Unity?
– The Nicene Legacy: How does the Council of Nicaea shape our ecumenical and interreligious commitments 1700 years later?
The Nicene Creed is common to all the churches of the Porvoo Communion and therefore is a strong foundation for our unity. Across a wide–ranging set of contributions, the Conference explored the tension between the Nicene Creed as a static formulation of belief and a lived expression of faith in worship.
The annual meeting of the Porvoo Communion reaffirms our desire to work together in the mission of the Church as Lutherans and Anglicans in Europe, learning from each other as churches. This will continue in 2026, when the Primates and Presiding Bishops of the Porvoo Communion will meet in England.
Archbishop Michael Jackson, the Anglican co–chair, preached at the concluding Eucharist of the Conference. You can read his service by clicking here.
