Readers can find the formal announcement on the English Ordinariate from the Catholic Bishops Conference of England and Wales here. The announcement has a lot of information on what and what not to expect from the Ordinariate. It is a sort of FAQ. But one thing is really notable.
The English and Welsh bishops do not use the phrase "Anglican Ordinariate" to describe the new ecclesial structure. The bishops use "Personal Ordinariate" and in the future it will be simply just referred to as "The Ordinariate".
Perhaps this is to take into consideration Anglican sensibilities and to avoid confusion. And this is what is called in American English "the 64 thousand dollar question"
Will members of the Ordinariate still be Anglicans?
The bishops conference answers with a "No". Members of the Ordinariate are Catholics.
The English Ordinariate will be the trial balloon. Other Ordinariates will be established in other countries. In these countries where there is no religious establishment, the Ordinariates may be known as the Anglican Ordinariate (Roman Catholic).
