Is it unusual for a Catholic bishop to be given the use and pastoral care of a Catholic parish?
The ‘Personal Ordinariate of Our Lady of Walsingham’ is an English Catholic group established last year for members of the Church of England joining the Catholic Church. Their leader, or ‘Ordinary’, is Monsignor Keith Newton, a former Anglican bishop. They retain some Anglican usage in their liturgy.
They now have their own parish church in London.
