Dicastery for Evangelization in the context of "Apostolic prefecture"

An apostolic vicariate is a territorial jurisdiction of the Catholic Church under a titular bishop centered in missionary regions and countries where dioceses or parishes have not yet been established. The status of apostolic vicariate is often a promotion for a former apostolic prefecture, while either may have started out as a mission sui iuris. It is essentially provisional, though it may last for a century or more. The hope is that the region will generate sufficient numbers of Catholics for the Church to create a diocese one day.

It is exempt under canon law, directly subject to the missionary Dicastery for Evangelization of the Vatican in Rome. Like the stage of apostolic prefecture which often precedes it, the vicariate is not part of an ecclesiastical province. It is intended to mature in developing Catholic members until it can be promoted to a (usually suffragan) diocese.

An apostolic prefect or prefect apostolic is a priest who heads what is known as an apostolic prefecture, a 'pre-diocesan' missionary jurisdiction where the Catholic Church is not yet sufficiently developed to have it made a diocese. Although it usually has an (embryonal) see, it is often not called after such city but rather after a natural feature, or administrative geographical area, which may be a name in use by the local inhabitants, or one assigned by a colonial authority, depending on the circumstances under which the prefecture was established.

If a prefecture grows and flourishes, it may be elevated to an apostolic vicariate, headed by a titular bishop, in the hope that with time the region will generate enough Catholics and stability for its Catholic institutions, to warrant being established as a diocese. Both these stages remain missionary, hence exempt, that is, directly subject to the Holy See, specifically the Dicastery for Evangelization, rather than, as a diocese normally would, belong to an ecclesiastical province.

In the canon law of the Catholic Church, a mission sui iuris (Latin: missio sui iuris, pl. missiones sui iuris), also known as an independent mission, can be defined as: "an ecclesial structure erected from a previous territory, with explicit boundaries, under the care of a religious community or other diocese, responding to a missionary exigency and headed by a superior nominated by the Holy See, under the aegis of the Congregation for the Evangelization of Peoples."

It is generally applied to an area with very few Catholics, or in areas where Christianity (in particular Roman Catholicism) is either outlawed or undergoing persecution, often desolate or remote, and ranks below an apostolic prefecture and an apostolic vicariate.

The Dicastery for Bishops, formerly named Congregation for Bishops (Latin: Congregatio pro Episcopis), is the department of the Roman Curia of the Catholic Church that oversees the selection of most new bishops. Its proposals require papal approval to take effect, but are usually followed. The Dicastery also schedules the visits at five-year intervals ("ad limina") that bishops are required to make to Rome, when they meet with the pope and various departments of the Curia. It also manages the formation of new dioceses. It is one of the more influential Dicasteries, since it strongly influences the human resources policy of the church.

The jurisdiction of the Dicastery does not extend to mission territories, under the Dicastery for Evangelization, or areas managed by the Dicastery for the Eastern Churches (which has responsibility for all Eastern Catholics, and for Latin Catholics in the Middle East and Greece). Where appointment of bishops and changes in diocesan boundaries require consultation with civil governments, the Secretariat of State has primary responsibility, but must consult the Dicastery for Bishops. The Dicastery also have oversight of investigations into allegations of abuse and negligence by bishops.

Missionary work of the Catholic Church has often been undertaken outside the geographically defined parishes and dioceses by religious orders who have people and material resources to spare, and some of which specialized in missions. Eventually, parishes and dioceses would be organized worldwide, often after an intermediate phase as an apostolic prefecture or apostolic vicariate. Catholic mission has predominantly been carried out by the Latin Church in practice.

In the Roman Curia, missionary work is organised by the Dicastery for Evangelisation.
