A Byzantine Catholic

[Vico]

Can. 515 §1. A parish is a certain community of the Christian faithful stably constituted in a particular church, whose pastoral care is entrusted to a pastor (parochus) as its proper pastor (pastor) under the authority of the diocesan bishop.

§2. It is only for the diocesan bishop to erect, suppress, or alter parishes. He is neither to erect, suppress, nor alter notably parishes, unless he has heard the presbyteral council.

§3. A legitimately erected parish possesses juridic personality by the law itself.

Can. 518 As a general rule a parish is to be territorial, that is, one which includes all the Christian faithful of a certain territory. 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.

This the the CCL that says what a parish is and who are the members of the parish.

The eastern code CCEO shows that enrollment is in a Church sui iuris, and essentially the same about establishment of parishes as in the Latin code. There is reference to “the parish of the Church sui iuris of enrollment” showing that a parish belongs to a Church sui iuris. Statistics for a Church sui iuris may be based upon baptisms and conversions taken from it’s various parishes.

Canon 37
Every enrollment in a certain Church sui iuris or transfer to another Church sui iuris should be recorded in the baptismal register of the parish where the baptism was celebrated, even, as the case may be, in a Latin parish; if this cannot be done, it is to be kept by the proper pastor in another document in the archive of the parish of the Church sui iuris of enrollment.

Canon 588
Catechumens are free to enroll in whatever Church sui iuris they want, according to the norm of can. 30; however, it has to be provided that nothing stands in the way of their enrollment in the Church that is more appropriate to their culture.

Canon 279
A parish is a definite community of the Christian faithful established on a stable basis in the eparchy, whose pastoral care in entrusted to a pastor.

Canon 280

1. Generally, a parish is to be territorial, that is, it embraces all the Christian faithful of a certain territory; if however, in the judgment of the eparchial bishop, having consulted the presbyteral council, it is expedient, personal parishes are to be erected based on nationality, language, enrollment of the Christian faithful in another Church sui iuris or even upon some other definite determining factor.
2. It is the competency of the eparchial bishop to erect, modify and suppress parishes after consulting the presbyteral council.
3. A lawfully established parish is a juridic person by the law itself.

In many Roman dioceses, the various EC parishes physically within the territory are designated as personal parishes for Romans attached to that parish’s particular ritual expression. I’m in one such parish; the pastor has no obligation to inform nor request permission from the registered parishioners’ territorial latin pastor, because, by their interest in the Ruthenian Church, they are elligible to be enrolled as canonical members of the parish despite the difference of enrollment of Church Sui Iuris.

On the other hand, it’s also designated as the territorial parish of all persons of the Eastern Churches in Union within the physical boundaries of the Roman Church ecclesiastical province of Alaska. (Rev. Fr. Mike had to give the permissions, and restrictions, for a couple in Fairbanks, some 400 miles away, who were of two different rites… IIRC, one Chaldean and one Syrian…)

 

[Hesychios]

If someone who is of the Roman Rite becomes a member of a Byzantine Catholic parish and practices the Byzantine faith regularly can they call themselves Byzantine Catholic, or do they need to switch rites to earn that title of sorts.

Not that I agree it should be this way, but if said person wanted to get married in that parish it would be impossible without outside permission (easy to get, but telling) and such a one could not pursue a vocation and hope to serve that parish or that church.

So the individual would be a Byzantine Catholic, but not really
