The Latin text of AC (thanks, Joshua) has one or two points of interest; I suspect that there is clearly at least one place at which a deliberate alteration has been made in the sense of the provisional English text. The phrase "the Anglican Communion" has disappeared, to be replaced by the word "Anglicanismum". I suspect that this might have something to do with accomodating the Continuum: Anglican groups which might not technically be categorised as part of the Anglican Communion as recognised by Canterbury.
Felicitously, the English phase that disunity "wounds that which the Church is and that for which the Church exists" is replaced by the statement that it "gravely wounds the mystery of the Church". This raises it to a more theological level, yes? And eliminates woffle.
"In a corporate manner" is replaced by the adverb "glomeratim", which means "in a ball, in a mass". This distinctly suggests a mass movement. It cannot bear the meaning that each individual seeking admission must belong to a local group; it clearly indicates that the Holy Father discerns a mass movement towards unity, and that this is what he is providing for. This is important. There is, for example, manifestly no ground in AC for limitations in the number of Anglican clergy who can be admitted to the presbyterates of Ordinariates. VI (1) says that the Ordinary can accept Anglican deacons, priests, and bishops who enjoy the qualities demanded by Canons 1026-1032. None of these canons, as far as I can see, gives any grounds for thinking that a priest who "doesn't have a group" should not be allowed to enter into the presbyterate of the Latin Church by means of the Ordinariate structures.
This is very important. It is necessary that the Ordinariates should have a large number of available clergy. Those who have served in the parochial ministry of any major denomination know the importance of a large pool of clergy - mostly retired - to oil the wheels. A pastor may need to go on holiday ... or go to a Deanery meeting ... or go on retreat ... or go and preach somewhere else ... . And solemn liturgy traditionally requires three sacred ministers; and solemn liturgy is something to which the Patrimony is very attached. Ordinariate groups may be small, but it would still be very difficult to pastor them on one priest and a retired priest (not least because retired clergy can also have commitments). The nearest Ordinariate group could be a hundred miles away; its clergy might not find it terribly convenient to travel such distances in order to cover my 12.30 Low Mass on Friday and Wednesday. And if I have to be away on a Sunday, and the local RC priest is already having to trinate in order to serve the churches in his care, he might not be terribly enthusiastic when I phone him up to ask if he can cram another Mass in for an Ordinariate group. It is clear that Ordinariates may not be able to pay a large number of clergy, and I certainly do not suggest that the local RC hierarchy should have to unearth money to do so; but it would be very wrong if extremely experienced clergy, retired and living on their C of E pensions, and desirous of exercising their priesthood in Full Communion, were, in effect, told that they could only enter Ordinariates in the lay state. Don't forget that retirement in the Church of England tends to happen much earlier than in the RC Church. Are droves of healthy active priests in their sixties really to be declared clerically redundant under the Ordinariate system? Are we sure that this is what the Holy Father has in mind?
And, if all one hears about the age profile of the Roman Catholic clergy in some places is true, you would have thought that Roman Catholic clergy themselves would distinctly welcome the advent of a large new pool of clergy whom they can "try" for occasional - or, indeed, more than occasional - duty. Being incardinated into an Ordinariate does not mean that one can't be lent. In the Good Old Days of the Irish Church, it lent clergy in shiploads to dioceses all over the world. To this day, there are probably many more Irish clergy working outside than there are inside Ireland. There is no reason why Ordinariates could not make a modest, and enthusiastic, contribution to staffing in the dioceses.
