Nuncio in the context of "John XXIII"

A prelate (/ˈprɛlət/) is a high-ranking member of the Christian clergy who is an ordinary or who ranks in precedence with ordinaries. The word derives from the Latin praelatus, the past participle of praeferre, which means 'carry before', 'be set above or over' or 'prefer'; hence, a prelate is one set over others.

The archetypal prelate is a bishop, whose prelature is his particular church. All other prelates, including the regular prelates such as abbots and major superiors, are based upon this original model of prelacy.

A diocesan bishop, within various Christian traditions, is a bishop or archbishop in pastoral charge of a diocese or archdiocese. In relation to other bishops, a diocesan bishop may be a suffragan, a metropolitan (if an archbishop) or a primate. They may also hold various other positions such as being a cardinal or patriarch.

Titular bishops in the Roman Catholic Church may be assistant bishops with special faculties, coadjutor bishops (these bishops are now named as coadjutors of the dioceses they will lead, and not as titular bishops), auxiliary bishops, nuncios or similar papal diplomats (usually archbishops), officials of the Roman Curia (usually for bishops as heads or deputies of departments who are not previous ordinaries), etc. They may also hold other positions such as cardinal. The see of titular bishop is only nominal, not pastoral- meaning he does not exercise final authority as the head bishop (the ordinary), or have the right to automatically succeed the aforementioned individual (the coadjutor), over an existing diocese or archdiocese or their Eastern rite equivalents, (arch-)eparchies. Titular bishops may be active or retired. Occasionally, as a priest, they may have been given a titular bishopric or archbishopric as an honor by the Pope, similar to when he names some cardinals.

The diplomatic corps (French: corps diplomatique) is the collective body of foreign diplomats accredited to a particular country or body.

The diplomatic corps may, in certain contexts, refer to the collection of accredited heads of mission (ambassadors, high commissioners, nuncios and others) who represent their countries in another state or country. As a body, they usually only assemble to attend state functions like a coronation, inauguration, national day or State Opening of Parliament, depending on local custom. They may also assemble in the royal or presidential palace to give their own head of state's New Year greeting to the head of state of the country in which they are based.

Guillaume de Bray (born at Bray in the Ile-de-France, date unknown; died in Orvieto, 29 April 1282) was a French ecclesiastic and Roman Catholic Cardinal, poet, and mathematician.

It is claimed Guillaume was Master of Theology, but the Cardinal's tombstone indicates that he was learned in Canon and Civil Law. There is no reference to him ever having been a Papal Legate, a Nuncio, or a provincial Rector (governor). So far as it is known, his career as a cardinal was entirely inside the Roman Curia.

Pope Paul IV (Latin: Paulus IV; Italian: Paolo IV; 28 June 1476 – 18 August 1559), born Gian Pietro Carafa, was head of the Catholic Church and ruler of the Papal States from 23 May 1555 to his death, in August 1559. While serving as papal nuncio in Spain, he developed an anti-Spanish outlook that later coloured his papacy. In response to an invasion of part of the Papal States by Spain during his papacy, he called for a French military intervention. After a defeat of the French and with Spanish troops at the edge of Rome, the Papacy and Spain reached a compromise: French and Spanish forces left the Papal States and the Pope thereafter adopted a neutral stance between France and Spain.

Carafa was appointed bishop of Chieti, but resigned in 1524 in order to found with Saint Cajetan the Congregation of Clerics Regular (Theatines). Recalled to Rome, and made Archbishop of Naples, he worked to re-organise the Inquisitorial system in response to the emerging Protestant movement in Europe, any dialogue with which he opposed (the inquisition itself had been first instituted by Pope Innocent III who first regulated inquisitional procedure in the 13th century). Carafa was elected pope in 1555 through the influence of Cardinal Alessandro Farnese in the face of opposition from Charles V, Holy Roman Emperor. His papacy was characterised by strong nationalism in reaction to the influence of Philip II of Spain and the Habsburgs. The appointment of Carlo Carafa as Cardinal Nephew damaged the papacy further, and scandals forced Paul to remove him from office. He curbed some clerical abuses in Rome, but his methods were seen as harsh. He would introduce the first modern Index Librorum Prohibitorum or "Index of Prohibited Books" banning works he saw as in error. In spite of his advanced age, he was a tireless worker and issued new decrees and regulations daily, unrelenting in his determination to keep Protestants and recently immigrated Marranos from gaining influence in the Papal States. Paul IV issued the Papal bull Cum nimis absurdum, which confined Jews in Rome to the neighbourhood claustro degli Ebrei ("enclosure of the Hebrews"), later known as the Roman Ghetto. He died highly unpopular, to the point that his family rushed his burial to make sure his body would not be desecrated by a popular uprising.

An apocrisiarius, the Latinized form of apokrisiarios (Greek: ἀποκρισιάριος), sometimes Anglicized as apocrisiary, was a high diplomatic representative during Late Antiquity and the early Middle Ages. The corresponding (purist) Latin term was responsalis ("he who answers"). The title was used by Byzantine ambassadors, as well as by the representatives of bishops to the secular authorities. The closest modern equivalent is a papal nuncio; the title apocrisiarius is also still employed by the Anglican Church.
