The Diocese of Chichester and Chichester Cathedral have revealed special plans to mark two important anniversaries next year.

On Sussex Day (Sunday, June 16) they said Sussex would celebrate the Christian faith in 2025, marking the 950th anniversary of the Diocese of Chichester and Chichester Cathedral, as well as the 1700th anniversary of when the Nicene Creed first emerged.

A spokesperson said: “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.”

They said many events are being organised to celebrate both anniversaries.

The Bishop of Chichester, Dr Martin Warner, said : “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 said: “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.”
