An apostolic administrator in the Roman Catholic Church is a prelate appointed by the Pope to serve as the ordinary for an apostolic administration. An apostolic administration can either be an area that is not yet a diocese (a stable apostolic administration) or for a diocese that either has no bishop (an apostolic administrator sede vacante, as after an episcopal death) or, in very rare cases, has an incapacitated bishop (apostolic administrator sede plena).
Apostolic administrators of stable administrations are equivalent in canon law with diocesan bishops, meaning they have essentially the same authority as a diocesan bishop. This type of apostolic administrator is usually the bishop of a titular see.
Administrators sede vacante or sede plena only serve in their role until a newly chosen diocesan bishop takes possession of the diocese. They are restricted by canon law in what they can do to the diocese they temporarily administer. For example, such an administrator may not sell real estate owned by the diocese. This type of administrator is commonly an auxiliary bishop of the diocese, a priest serving as the vicar general of the diocese, or the ordinary of a neighboring diocese.
Normally when a diocese falls vacant, a vicar capitular/diocesan administrator is chosen locally, but the Pope, having full governmental power, can preempt this choice and name an apostolic administrator instead. Sometimes a retiring bishop is designated to be apostolic administrator until his successor takes office.
In May 2015, there were the following stable apostolic administrations, most administered by a (titular or extrenal) bishop.
Most are of the Roman rite; most are in current or former communist countries.
- Apostolic Administration of Atyrau, in Kazakhstan, suffragan of the Metropolitan Archbishopric of Astana; on Saturday, May 16, 2015, Pope Francis named the Reverend Father Dariusz Buras, of the clergy of the Roman Catholic Diocese of Tarnow in Poland, and since 2010, serving as Parochial Vicar of the Cathedral of Oslo, Norway; born on November 16, 1971 and ordained on May 30, 1998; received a Licentiate in spiritual theology from Warsaw's Cardinal Stefan Wyszynski University in 2007
- Apostolic Administration of the Caucasus, immediately subject to the Holy See, established in 1991 for two predominantly Orthodox former Soviet Republics: Georgia (the cathedral is in its capital Tbilisi) and Armenia
- Apostolic Administration of Estonia, one of the Baltic Countries; immediately subject to Rome, established in 1924, with its cathedral in the capital Tallinn
- Apostolic Administration of Kyrgyzstan, a mainly Islamic former Soviet Republic in Central Asia; immediately subject to Rome, founded in 1997 as a mission sui juris and promoted in 2006
- Apostolic Administration of Prizren, a former diocese (and later titular bishopric) in Kosovo (ex-Yugoslavian autonomous province in Serbia) (in 1969 absorbed by Skopje in the present Republic of Macedonia), restored in 2000, immediately subject to Rome
- Apostolic Administration of Uzbekistan, predominantly Islamic former Soviet Republic in Central Asia, immediately subject to Rome, founded in 1997 as a mission sui juris and promoted in 2005
- Apostolic Administration of Harbin in the People's Republic of China, immediately subject to Rome, established in 1935, with a cathedral, with two incumbents, a bishop without papal mandate since 2012 and a papal nominee since 2011
The only exception, belonging to a Uniate, Eastern Catholic rite, is the following :
- Apostolic Administration of Southern Albania, with cathedral see at Vlorë (established in 1939; suffragan of the metropolitan of Tirana–Durrës), of the Albanian Byzantine Catholic Church, which as its own Albanian rite.
- Kinma (Kinmen and Matsu, under the control of the Republic of China (Taiwan)), established in 1968, led by the Archbishop of Taipei.
Diocese of Pyongyang
The Diocese of Pyongyang, North Korea: its last official bishop, Francis Hong Yong-ho, was imprisoned by the communist regime of Kim Il-sung in 1949 and later disappeared. The Archbishop of Seoul (South Korea) acts as the Apostolic Administrator in Pyongyang, as religion is suppressed in North Korea.
It has become not unusual that the Pope appoints an Apostolic Administrator to a diocese which is sede vacante, thus replacing the diocesan administrator. Usually, the emeritus bishop will be appointed in such a case. Presently (and in exception to the latter), the archdiocese St. Andrews and Edinburgh has Philip Tartaglia under this procedure.
Personal Apostolic Administration of Saint John Mary Vianney
In addition, the Personal Apostolic Administration of Saint John Mary Vianney is a non-territorial jurisdiction, similar to a personal prelature, which is exempt, i.e. immediately subject to the Holy See, not part of any ecclesiastical province. It is a separate particular church for traditionalist Catholics within the Brazilian Diocese of Campos, a suffragan of the Metropolitan Archdiocese of Niterói.
The personal apostolic administration was formed by Pope John Paul II to administer to a group of traditionalist Catholic priests, using the Tridentine Mass, who reconciled with Rome on January 18, 2002. The group had been formed by bishop Antônio de Castro Mayer and had been associated with the Society of St. Pius X of Archbishop Marcel Lefebvre.
