The Anglican Communion is a broad church. A product of the Protestant Reformation, it has always included those who think of themselves as Catholic, while separated from the wider Church. This has been reflected in their patterns of worship, which have in varying degrees blended Catholic practice with Anglican liturgical forms.

In 2009, Pope Benedict XVI authorised the creation of “Personal Ordinariates” for Anglicans who wished to enter into full communion with the Catholic Church, while retaining distinctive elements of their own patrimony. An Ordinariate is equivalent to a diocese which may exist in the same place as other dioceses, for the care of those attached to it. Three were created: The Personal Ordinariate of Our Lady of Walsingham (Britain), The Personal Ordinariate of the Chair of St Peter (North America), and The Personal Ordinariate of the Southern Cross (Australia and Asia).

The Ordinariates have their own form of the Roman Rite, authorised by Pope Fancis, which incorporates language and prayers from the Anglican Books of Common Prayer. The liturgical books encompass Mass, Office and occasional services such as Baptism and Marriage. They are collectively known as Divine Worship.
