Almost 500 years after the Church of England's formal break with Rome, in an Apostolic Constitution Anglicanorum Coetibus,Pope Benedict XVI invited Anglicans to enter into full communion with the Catholic Church as groups, bringing with them their traditions and their liturgy as a "treasure to be shared".

Anglicanorum Coetibus was promulgated on 4th November 2009 and led to the formal establishment of the Personal Ordinariate of Our Lady of Walsingham in January 2011. This book, fifteen years on, with a Foreword by Bishop David Waller, tells the story of how and why it happened - and looks to the future of a Church enriched by the heritage of an Anglican culture loved by generations.
