Nah, Tim, I neither knew that nor agreed with that. My own careful reading of Canon 515 and following indicates nothing of the sort. Further, let me quote Fr. Serpa’s two answers from AAA:
While one is certainly free to go to Mass wherever one likes, technically, one is inherantly a member of one’s georgraphic parish, no matter where they might attend or be registered. Now, it could be argued that were one to register at an “personal” parish, that they are no longer the responsibility of the pastor of the geographic parish, but it could also be argued that they have TWO parishes - one geographic, one personal. Further, if one is simply registered at a parish it does not necessarily mean that they are a member in quite the same way that they would be if there were attended a formally established personal parish. I know people who are registered at several parishes, afterall. Are they formally a member of them all? And are they NOT a member of their geographic parish if they never bothered to register there?
This is certainly germane to the topic because of “personal parishes.” Canon Law states in Can 518 :“When it is expedient, however, personal parishes are to be established determined by reason of the rite, language, or nationality of the Christian faithful of some territory, or even for some other reason.” Certainly that reason could be the TLM. And, after they registered, those parishioners would be members of that parish and see and non their geographical one. The 1983 Canon cleared this up.
I’m not sure that the canon really did clear things up. If anything, it may have muddied the waters a bit more. (Though, really, is the entire personal parish idea anything new? Obviously, no, as we had many ethnic parishes here in town a century ago.) One pastor commented that the way he reads canon law, he figures that you could legitimately have as many as
FIVE parishes! Certainly, the bishop of the parish which you regularly attend would have jurisdiction over it’s functioning. And you’d be accountable as far as your involvement with that parish goes. But does that, ultimately, mean that you are unaccountable to the bishop of the diocese where you reside? I don’t think it does.
Who, ultimately, has jurisdiction over Catholics, then, and for what is perhaps yet unanswered and debateable. Indeed, “parish” (or even diocese) hopping has created a whole new phenomenon and challenge for the Church and a serious question of who is responsible for whom and what.
