The FSSP gets to elect its superior general. A prelature does not get to elect the prelate. The prelate is appointed by the pope.
JP 2 appointed the first Opus Dei Prelate, after that they elect their own who is confirmed by the Pope.
The FSSP has to ask for permission to enter a diocese, so does the prelature.
Actually, they don’t. The Prelature of Opus Dei, by it’s own Code, can, indeed, enter a Diocese without the knowledge or consent of the local Ordinary through the erection of a dependent Center, or in a few other ways. Mostly through the Personal or Dependent Center, though. In fact, there can be a Center complete with Oratory that is reserving the Eucharist, having Mass, and so forth, without the local knowing a thing about it.
The prelature has ordinary authority over the laity. Guess who is morally responsible for the laity . . . bingo! The prelature, not the local bishop,
Again, not at all how it works with Opus Dei, the only Prelature we really have to go by. The laity that attach to Opus Dei by contract do not change their Canonical status and are still under the jurisdiction of the local Ordinary. (Hence, Michael Voris had to change the name of his “apostolate.”) Now, this doesn’t stop the “faithful of Opus Dei” from abandoning their parishes and attending Mass and so forth only at an Opus Dei Center. But technically, they are under their Bishop. The Prelate only has authority over them in matters that concern the person and the Prelature by whatever contract they have between them, which, of course, each is able to end at any time.
Of course, these lay people mostly don’t go to Diocesan churches or donate to them or in any other way participate, but the legal issue is that they are under the local Ordinary.
If the SSPX decides to have a happy hour and there are complaints, the prelate has to deal with them and he has to inform the pope.
No he doesn’t. I have to ask where you are getting all these ideas? You know what it says in the CoCL about Prelatures? This is it:
PERSONAL PRELATURES (Cann. 294 - 297)
Can. 294 After the conferences of bishops involved have been heard, the Apostolic See can erect personal prelatures, which consist of presbyters and deacons of the secular clergy, to promote a suitable distribution of presbyters or to accomplish particular pastoral or missionary works for various regions or for different social groups.
Can. 295 §1. The statutes established by the Apostolic See govern a personal prelature, and a prelate presides offer it as the proper ordinary; he has the right to erect a national or international seminary and even to incardinate students and promote them to orders under title of service to the prelature.
§2. The prelate must see to both the spiritual formation and decent support of those whom he has promoted under the above-mentioned title.
Can. 296 Lay persons can dedicate themselves to the apostolic works of a personal prelature by agreements entered into with the prelature. The statutes, however, are to determine suitably the manner of this organic cooperation and the principal duties and rights connected to it.
Can. 297 The statutes likewise are to define the relations of the personal prelature with the local ordinaries in whose particular churches the prelature itself exercises or desires to exercise its pastoral or missionary works, with the previous consent of the diocesan bishop.
A prelature is like a diocese without physical boundaries. It certainly has many other boundaries and a lot more oversight from the Vatican.
Of course, I have no idea how much oversight the Pope exercises over Opus Dei, but they only have to submit a report of their activities every 4 or 5 years, I forget exactly. And whole a lot of people describe it like you did, like a Diocese without geographical boundaries, the one Prelature we have is organized like the Church more than anything you’d see in a Diocese as the Regional Counselors are defined by the Code as Vicars.
In fact, giving the SSPX standing as a Prelature really means the Pope is giving them the whole world as their operating arena, just like Opus Dei. One estimate puts the number of priests in Opus Dei, actual Opus Dei priests, not diocesan priests who associate with it, at over 20k. That’s not a diocese.
So, I’m thinking making the SSPX a Prelature, pretty sweet deal for them. In fact, the Vatican could just do away with the Diocesan system altogether.
