If I may say...

There are two issues w.r.t. Regional Bishops Conferences that perturb me (for which, on reflection, I am grateful that they haven't been more important in the past). First is the implied by-default subordination of... Ordinaries... to Sæcular order. Which is, quite simply, up-side-down. Or maybe "sideways", in the "it all went sideways" sense. Second: what do we do when the borders move? Because: It happens. It has happened in Germany and in the Balkans, in Living Memory. It might be happening in the Ukraine. It is almost certainly happening all over the Middle East (where, all things said, there are more important worries for the Local Ordinaries). There are still people who want it to happen in plenty more places. The Church, however, really ought to look more æternal than principalities.

So. There. That's my denarius' worth on the matter.
