The Right Reverend Justin Welby has become the new Bishop of Durham during a ceremony at the city's cathedral.
The new bishop knocked on the door of Durham Cathedral three times, as is traditional before taking on his new role.
He was previously the Dean of Liverpool before being asked to become the fourth most senior bishop in the Church of England.
Before becoming a priest, he spent 11 years in the oil industry.
During his first sermon, he said Christians had a role to play during economic hardship and it was a time of "opportunity".
He is due to stage a series of prayer meetings around the area as part of his Prayer for the People campaign.
He was also presented with a sword which, according to legend, was used in medieval times to slay a dragon.
