Nearly a thousand people packed into St Joseph's Cathedral to witness the installation of Peter Libasci as Manchester's tenth bishop.
Originally from Long Island, New York, Libasci was appointed to the position by Pope Benedict XVI in September of this year.
In his first address to the congregation, the newly instated Bishop thanked those in attendance, as well as other members of the church who were watching via television:
"To all of our civic leaders and all who've gathered here this day in this church, I hope are following this liturgy on television, here in New England, and on Long Island as well.
The Diocese of New Hampshire estimates that Libasci will be serving around 300,000 Roman Catholics in the state.
He succeeds Bishop John McCormack who announced his retirement in August.
