With the Church of England, it is the other way round. They are accustomed to having others make decisions for them (Synod &c), and in a direction they don't like. Autonomy has had to be wrested from those who would not willingly grant it. But for the most part they don't own their property and, as I have remarked before, the Church Commissioners are unlikely to feel in a generous mood. But perhaps I am being unduly cynical. Having listened to the Sunday Programme yesterday, I was struck how the three interviewed parties; an Evangelical bishop, a woman priest and academic and a bishop likely to accept the offer, all substantially agreed. The Evangelical and the lady were surprisingly warm about the scheme. And why wouldn't they be? Their jobs have just become a lot easier; there will now be only negligible opposition to their projects. This might dispose them to be in a generous mood and allow the secession of church buildings in places where there is a superabundance of them (as in Brighton, for instance). And, as I mentioned before, maybe a redundant church or two may be pressed into service.
The trouble is that, as I read on another blog (perhaps it was OneTimothyFour), lay Anglicans are disposed to love their bricks more than their bishops. I can envisage a situation whereby, if property transfer is not agreed, a large number of clergy may swim the Tiber, bringing their English Hymnals, their volumes of Pusey and the odd buckled shoe, but leaving their congregations behind, distressed at the choice they have had to make, but in the end prepared to put up with Bishop Susan and Father Margaret rather than leave St Disibod-by-the-Gasometer.
For some churches, I imagine this will not apply. I don't think all churches are owned by the Church Commissioners, or the Crown, or whoever. The shrine at Walsingham springs to mind (wouldn't it be wonderful to be able to worship there!) and maybe St Bartholomew's, Brighton (which made some very tentative enquiries Romeward in the early nineties). No doubt there are others. But if there really are going to be over a thousand clergy taking up the Pope's offer, then these churches are going to be like olden days, with a dozen curates each, or possibly a hundred. That won't do.
I don't imagine, either, that existing RC dioceses, many already strapped for cash, are going to be able to take on the burden of priests and families without there being some benefit to the diocese. It is possible that in England there may need to be some compromise worked out whereby priests are loaned by the Ordinariate to the dioceses to work in Roman Rite Catholic parishes, which then become liable for their support. These priests can offer Mass according to the Anglican form as and when needed or wished, maybe initially even in their Roman Rite parishes. Over time, congregations will gather, no doubt, and it should eventually become possible to find premises and become self-supporting, then being entirely under the supervision of the Ordinariate.
This loaning of priests from one jurisdiction to another (called fidei donum) is quite common in the Catholic Church, though I have not encountered it much in this country under that name. For some years this diocese sent priests to Chulucanas in Peru, and Portsmouth sent priests to Bamenda in Africa. Priests loaned to English dioceses would remain canonically part of the Ordinariate, and would return to work for it as soon as an opening became available.
