§2. A diocesan bishop can grant his clerics permission to move to another particular church for a predetermined period of time which can be renewed several times; such clerics remain incardinated in their own particular church and, when they return to it, they possess all the rights which they would have had if they had exercised the sacred ministry there.

§3. A cleric who has legitimately moved to another particular church while remaining incardinated in his own church can for a just cause be recalled by his own diocesan bishop provided the agreements made with the other bishop and natural equity are observed.; under the same conditions the diocesan bishop of the other particular church can likewise for a just cause deny the same cleric permission for a longer stay in his territory.

Can. 372 - §1. As a rule that portion of the people of God which constitutes a diocese or some other particular church is limited to a definite territory so that it comprises all the faithful who inhabit that territory.

Can. 383 - §1. In the exercise of his pastoral office a diocesan bishop is to show that he is concerned with all the Christian faithful who are committed to his care regardless of age, condition or nationality, both those who live within his territory and those who are staying in it temporarily; he is to extend his apostolic spirit to those who cannot sufficiently make use of ordinary pastoral care due to their condition in life and to those who no longer practice their religion.

§2. If he has faithful of a different rite within his diocese, he is to provide for their spiritual needs either by means of priests or parishes of that rite or by means of an episcopal vicar.

Can. 516 - §1. Unless the law provides otherwise, a quasi-parish is equivalent to a parish; a quasi-parish is a definite community of the Christian faithful within a particular church which has been entrusted to a priest as its proper pastor but due to particular circumstances has not yet been erected as a parish.

§2. If the diocesan bishop would decide that due to a dearth of priests a participation in the exercise of the pastoral care of a parish is to be entrusted to a deacon or to some other person who is not a priest or to a community of persons, he is to appoint some priest endowed with the powers and faculties of a pastor to supervise the pastoral care.

Can. 518 – As a general rule a parish is to be territorial, that is it embraces all the Christian faithful within a certain territory; whenever it is judged useful, however, personal parishes are to be established based upon rite, language, the nationality of the Christian faithful within some territory or even upon some other determining factor.

§2. The pastor is to acknowledge and promote the proper role which the lay members of the Christina faithful have in the Church’s mission by fostering their associations for religious purposes; he is to cooperate with his own bishop and with the presbyterate of the diocese in working hard so that the faithful be concerned for parochial communion and that they realize that they are members both of the diocese and of the universal Church and participate in and support efforts to promote such communion.
