Seventeen former Anglican priests were made deacons in one of the largest group ordinations in the modern history of the Catholic Church in Britain.
All the deacons will serve in the Personal Ordinariate of Our Lady of Walsingham, which in January 2011 became the first ordinariate to be set up under Anglicanorum coetibus, the apostolic constitution issued by Pope Benedict to allow the group reception of Anglicans.
Father James Bradley, spokesman for the ordinariate, said he expects that all the deacons, about half of whom are married, will be ordained to the Catholic priesthood over the summer.
The men were ordained at London's Westminster Cathedral.
More ordinations to the diaconate are expected over the summer.
