The Congregation for the Doctrine of the Faith, in the name of Pope Benedict, is providing a formal way (a canonical structure) of allowing Anglicans to enter in Full Communion with the Catholic that sets up a structure similar to that of Opus Dei. Instead of calling the structure a “prelature” it is being called a “Personal Ordinariat.” Many things attributed to the Anglican Communion may be brought into their being Catholic including the Liturgy, married clergy, and other customs not in conflict with the Roman faith.

This step is a concrete realization of the hard work done in the ecumenical dialogues the goal of which is full, visible union in the Church of Christ.
