For many contemplating participation in an Ordinariate, their church is a make-or-break element. One might say with justice that such people do not see the issues clearly enough, that if they really believed in the Catholic faith, they would know what they needed to do.
But abandoning the religious solace that they have found in St Disibod's by the Gasometer for a Great Unknown is a big ask.
Now, could an aspiring Ordinariate priest bring his church building with him, then most things would stay more or less the same, and in some cases almost all churchgoers would probably go along with it.
However, this relies on good will from the Church of England. They must either gift the building, or permit its use by an Ordinariate congregation, free of charge, or for a rent.
Why they might say yes:
Owning a church building without its people paying to support it is in no way desirable, especially if it is a listed building. This would become a heavy burden on the Church Commissioners who would strive to have it made redundant, no doubt, or converted for other use.
This leaves them looking like the bad guys. The former congregation are camping out in some other building, while the church they have loved for years is locked against them for no apparent good reason. This could sow the seeds for years of bad feeling in the neighbourhood.
Why they will probably say no.
Being permitted to 'take their church with them' will result in accusations from the Womens Ordination lobby of 'rewarding misogyny'. They feel themselves to be on higher moral ground, so they will not hesitate to say this.
My guess is that the Church Commissioners will gamble on the majority of the parishioners remaining (reluctantly or otherwise) in the Church of England for the sake of their parish church, and 'everything staying as it has always been at St Disibod's'. There will be bitter recriminations (with a bit of a bad conscience) about the priest 'abandoning us', and after a very long interregnum, an affirming Catholic male priest will get the incumbency (the PCC will be so relieved after a long period to get somebody, and especially a man) who will be able to soften things up in the parish. He will naturally be followed by Father Susan.
For the Church of England, a satisfactory solution all round.
It does not, however, look at the underlying good of souls. I have seen on Bishop Barnes' blog, and on Fr Hunwicke's lamentations on the steady disappearance of good Anglo Catholic parishes. This means that those parishioners who feel unable to cope with Fr Susan, or even Fr Rainbow her Aff-Cath predecessor, will have nowhere to go where they can feel comfortable.
There is no Sunday Obligation in the Church of England, just a general encouragement to attend Mass. Bit by bit, people affected by this change will simply cease to practise their religion. Some may adapt to the new state of affairs, some even like it once they've got used to it. But many will simply be lost.
There is a lot more one might say, and no doubt some of you may like to comment. I just hope that the Church of England takes the pragmatic and charitable view; in towns where there is a superfluity of churches, to permit a church building to continue to accommodate those who have loved and paid for it, sometimes over generations, is not just a work of charity, but, I suggest, of justice.
