Role of coadjutor In the Latin Church, the pope may appoint a bishop as coadjutor to help the
diocesan bishop govern the
diocese. Being himself a bishop, the coadjutor can substitute for the diocesan bishop in his absence (Canon 403§3). Under
canon law, the coadjutor must serve as the
vicar general, the principal deputy administrator of the diocese. The diocesan bishop must "entrust to him [coadjutor] before others" in acts that require a special mandate (Canon 406§1) If the
episcopal see is an
archdiocese, the coadjutor is appointed as an
archbishop. In modern church practice, the pope can appoint a coadjutor to assist a bishop who needs help due to declining health. The coadjutor can also assist a bishop nearing retirement. The objective is to have continuity of leadership in the diocese and avoid an unexpected vacancy in the position of bishop. In some situations, the pope may appoint a coadjutor to override the diocesan bishop in certain matters. These might include a public scandal or financial mismanagement of the diocese. The problems are serious, but not bad enough for the pope to remove the diocesan bishop. For example, in 2023,
Pope Francis appointed Bishop
François Touvet as coadjutor of the
Diocese of Fréjus-Toulon in France to assist the elderly Bishop
Dominique Rey. The pope gave Touvet special powers to oversee the preparation of
seminarians and the financial management in the diocese. The
Vatican had suspended the
ordination of priests in the diocese in 2022. In one instance, the pope appointed a coadjutor to a church that was not a diocese. In 2002,
Pope John Paul II named the Reverend
Fernando Arêas Rifan as coadjutor of the
Personal Apostolic Administration of Saint John Mary Vianney in Brazil. The pope took this action as part of the reconciliation agreement with the former Priestly Union of Saint John Mary Vianney that had broken with the Catholic Church.
Right of succession The 1983
Code of Canon Law of the Latin Church stipulates that all coadjutors have the right of succession. The code also allows the pope to appoint an auxiliary bishop to a diocese "with special faculties [powers]", but without the right of succession. For example, in 1986,
Pope John Paul II appointed the Reverend
Donald Wuerl as an auxiliary bishop in the
Archdiocese of Seattle in Washington State in the United States with "special powers" to override Archbishop
Raymond Hunthausen. The pope was unhappy with Hunthausen's handling of
LGBTQ relations and other morality issues. Under the old
1917 Code of Canon Law, the pope did not have to name a coadjutor
cum jure succesionis ("with the right of succession"). In practice, popes sometimes appointed coadjutors without the right of succession. These coadjutors usually served in large archdioceses. They might hold other important posts within the Catholic Church, or might be auxiliary bishops that the pope wanted to honor with the title of coadjutor. For example,
Pope Paul VI in 1965 appointed Auxiliary Bishop
John J. Maguire as coadjutor of the
Archdiocese of New York, one of the largest archdioceses in the United States, to assist Cardinal
Francis Spellman. However, the pope denied Maguire the right to succeed Spellman, who died in 1967. == Eastern Catholic Churches ==
