The new Archbishop of Canterbury, Justin Welby, was officially enthroned at Canterbury Cathedral on Thursday (March 21st) as part of his official instalment on the diocesan throne to cheers from the congregation of religious leaders, royalty and politicians.

Welby used his sermon to declare that he is hopeful for the future of the Christian church in Britain and overseas.

"There is every reason for optimism about the future of the Christian faith in our world and in this country. Optimism does not come from within us, but because to us and all people, Jesus comes to us and says 'Take heart, it is I, do not be afraid'."

The Archbishop of Canterbury is the leader of the Church of England and spiritual head of the world's 77 million Anglican.

African drummers performed during the service, reflecting Welby's many years spent working on the continent.

Welby is a former oil man who gave up a high salary to train as a priest. He spent many years in Africa and the service was due to have a strong African flavour with music and dance.

Welby has big challenges ahead and inherits a church which is declining in numbers and is divided on issues like women bishops and sexuality.

He is the 105th Archbishop of Canterbury who succeeds Rowan Williams, who left after a decade in office at the end of December to take up a new post as master of Magdalene College, Cambridge.
