Diocese of Chichester

2025 marks the 950th anniversary of the formation of the Diocese of Chichester and Chichester Cathedral and 1700 years since the Nicene Creed first emerged.

In 1075 the decision was made to move the seat of the Bishop from Selsey to the more populous town of Chichester, the former Roman settlement known as Noviomagus.

The original Cathedral and Bishop's Palace were rebuilt on the present site in the early 13th century after a disastrous fire. The Diocese retains its original boundaries, serving the people of East and West Sussex and Brighton and Hove.

2025 also marks the 1700th anniversary of the Council of Nicaea which resulted in the Nicene Creed emerging - a document still recited by Christians summarising the essence of what they believe.

A wide range of events celebrating both anniversaries are in the process of being organised.

The Bishop of Chichester, Dr Martin Warner, said today: "This momentous celebration reminds us that we cannot define God. Faith is an exploration in which we risk everything to glimpse the mystery of God’s glory and to discover our place in his heart of love.

He added: "All of these will serve to inspire and strengthen our faith as we seek together to know, love, and follow the Lord Jesus in 2025 and beyond. We look forward to sharing more details of Celebrating Faith and Chichester950 with you in due course.”.

With regards to the events marking the anniversary of the Creed, the Bishop said: “The programme in 2025 will explore how the Creed unites us in what we believe about God, who is Father, Son, and Holy Spirit.

For the Diocese, celebrations will come under the banner of Celebrating Faith, and will include:
- A celebration service in every deanery across East and West Sussex;
- A weekend away for young families;
- Pilgrimages for young people and parishes across the deaneries;
- A Lent Course focussing on the essential elements of the Creed;
- A clergy conference in Canterbury;
- An international ecumenical conference in Chichester marking the anniversary of the Nicene Creed.
