I was half expecting an announcement from Rome on the Westminster succession last week, half expecting because I thought it strange for the present incumbent to be in Rome, if an announcement was going to made in his diocese.
The rumours are that the Congregation for Bishops have discussed this three times already, which would suggest that the current Archbishops have been weighed in the balance and found wanting, now the suggestion is being put around that we should expect to hear nothing until after Easter, maybe. I think it is unlikely an announcement will be made whilst the Pope is in Africa next week.
My understanding is for most episcopal appointments the Congregation having received a terna from the relevant nuncio and diocese and comments from other interested bodies, as well as the Secretariate of State and the Congregation for the Doctrine of the Faith, who might well veto a particular name. A new terna is drawn up and submitted to the Pope, normally the Pope names the one at the top of the list. In the case of auxiliary bishops like Fr Wagner, the erstwhile nominee for Linz, the papal nomination is notional. In the case of Metropolitans and especially of those Sees which traditionally are headed by someone who will elect the Pope's successors, more care is given and the ope does directly intervene. After the Pope has named someone the nuncio contacts them, normally they are given 48 hours to consider the appointment and search the closets of their past for skeletons before the name is made public.
It seems to me that we should turn our attention to auxilliary bishops, religious superiors or notable parish priests, though if a consensus can't be reached on one of these we might be back to the Archbishops for a safe pair of hands, if one can be found.
The problem we have in England is that those who might have proved most attractive as a Benedictine appointment have been kept in the shadows, they have not been appointed as seminary rectors, vicars general or auxilliary bishops.
