This is Austen Ivereigh's conclusion in his informative post on the America blog concerning Pope Benedict's Apostolic Constitution that was announced today both in Rome and in London.He writes:

Rome today has announced a legal means for disaffected Anglicans to become Roman Catholic while hanging on to their liturgies and rites. It is a major move by Pope Benedict XVI, the potential negative impact of which on relations between the two Churches was vigorously played down by the Archbishops of Westminster and Canterbury at a joint press conference this morning in London, where Dr Rowan Williams described relations between the Catholic and Anglican Churches as "business as usual".The new canonical structure has the technical name of a "Personal Ordinariate", which according to the Congregation for the Doctrine of the Faith (CDF) "will allow former Anglicans to enter full communion with the Catholic Church while preserving elements of the distinctive Anglican spiritual and liturgical patrimony". The Ordinary -- canonically, that means the one with power of governance -- would normally be "appointed from among former Anglican clergy", the CDF says.

In their joint Statement, to which Ivereigh refers, the two Archbishops declare:

Today's announcement of the Apostolic Constitution is a response by Pope Benedict XVI to a number of requests over the past few years to the Holy See from groups of Anglicans who wish to enter into full visible communion with the Roman Catholic Church, and are willing to declare that they share a common Catholic faith and accept the Petrine ministry as willed by Christ for his Church.Pope Benedict XVI has approved, within the Apostolic Constitution, a canonical structure that provides for Personal Ordinariates, which will allow former Anglicans to enter full communion with the Catholic Church while preserving elements of distinctive Anglican spiritual patrimony.The announcement of this Apostolic Constitution brings to an end a period of uncertainty for such groups who have nurtured hopes of new ways of embracing unity with the Catholic Church. It will now be up to those who have made requests to the Holy See to respond to the Apostolic Constitution.The Apostolic Constitution is further recognition of the substantial overlap in faith, doctrine and spirituality between the Catholic Church and the Anglican tradition. Without the dialogues of the past forty years, this recognition would not have been possible, nor would hopes for full visible unity have been nurtured. In this sense, this Apostolic Constitution is one consequence of ecumenical dialogue between the Catholic Church and the Anglican Communion.

Update:Since this is a developing story, there will be many further reflections. But I thought it worthwhile to provide a link to Ruth Gledhill's post on the website of The Times (of London) where she prints Archbishop Williams' Letter to the Bishops of the Church of England.
