THE longest-serving bishop still in office in the Anglican Communion, the Rt Revd Dinis Sengulane, who retired earlier this year (News, 28 March), came to the UK to celebrate his 38 years of episcopal ministry in Mozambique with his diocesan companion link in London, the Angola London Mozambique Association (ALMA), and the Mozambique and Angola Anglican Association (MANNA).

A special MANNA service was held in St John's, Waterloo, and one in St Paul's Cathedral, to mark the 16th ALMA Sunday. Representatives from the British Museum and Chatham House were present.

"Ola paz" ("Hello peace") is the acclamation associated with Bishop Sengulane. Since the end of the civil war in Mozambique, in 2002, through the project he set up - Transforming Arms into Tools - he has helped to take no fewer than 900,000 weapons out of use, and turn them into sculptures such as The Throne of Weapons and Tree of Life, which are in the British Museum. He is a member of the Council of State, and one of five mediators working to secure peace after the recent unrest. Peace and reconciliation, he says, will be at the heart of his work during his retirement.

During the ALMA service in the cathedral, Bishop Sengulane and the former chair of ALMA, the Rt Revd Michael Colclough, were presented with ALMA stoles in recognition of their service to the partnership between Angola, London, and Mozambique. They then prayed for the Bishop of Kensington, the RtRevd Paul Williams, who was commissioned as the new Bishop for ALMA, and the Archdeacon of Hackney, the Ven. Rachel Treweek, who is the new chair of the association.
