Following a comment from EPMS, I went to the facebook page of Blessed John Henry Newman Catholic Church, Irvine, an Ordinariate parish in Orange County, California, and watched this video:
Here we see Dustin Vu, a regular worshiper at Blessed John Henry Newman for some two years, who is going off to seminary to study for the priesthood “for the Diocese of Orange”. This is a young man who has spent perhaps his most decisive formative years as a young Catholic worshiping and collaborating in an Ordinariate parish, whose vocation has been “cultivated”, as Fr. Andrew Bartus puts in, in this Ordinariate parish, yet is beginning to train for the diocesan priesthood and not the Ordinariate priesthood. Why, you may ask, is this?
I am assuming that Dustin just does not fulfil the conditions for Ordinariate membership. As a cradle Catholic who completed the sacraments of initiation outside of the Ordinariate, the only way that he could qualify to become an Ordinariate Catholic would be to be a member of the family of a member of the Ordinariate. and this is probably not the case. The Complementary Norms for the Apostolic Constitution Anglicanorum Coetibus state:
“Those who have received all of the Sacraments of Initiation outside the Ordinariate are not ordinarily eligible for membership” (Complementary Norms, Article 5, § 1)
but do not clarify how “ordinarily” is to be interpreted. Are exceptions possible? It is not evident whether and under which conditions a person who has taken part in the activities of the Ordinariate for a longer period can apply for a transfer. So it would seem almost always to be the case that “once a cradle Catholic, always a diocesan Catholic”. This may seem unfair, even ludicrous to you, but that is the legal canonical position, as far as I can make out.
And this appears all the more strange if we study the Decrees of Erection of the Personal Ordinariates. where a simple, unbureaucratic method of leaving the Ordinariate and becoming a diocesan Catholic, i.e. a transfer in the other direction, is clearly provided for:
“If a member of the faithful wishes to leave the Ordinariate, he must make such a decision known to his own Ordinary. He automatically becomes a member of the Diocese where he resides.” (Decree of Erection of the Ordinariate of OLW, § 10)
To my mind, it would facilitate matters no end, if Rome provided for a method of qualifying to enter the Ordinariate after a number of years, perhaps five (or two for an adolescent).
