Information: - A cathedra (Latin, "chair", from Greek, "kathedra", "seat") or bishop's throne is the seat of a bishop. It is a symbol of the bishop's teaching authority in the Catholic Church, the Orthodox Church, and the Anglican Communion churches. "Cathedra" is the Latin word for a chair with armrests, and it appears in early Christian literature in the phrase ""cathedrae apostolorum"", indicating authority derived directly from the apostles; its Roman connotations of authority reserved for the Emperor were later adopted by bishops after the 4th century. A church into which a bishop's official "cathedra" is installed is called a cathedral. - A cathedral (French: "cathedrale" from Latin: "cathedra", "seat" from the Greek "kathedra" (), seat, bench, from "kata" "down" + "hedra" seat, base, chair) is a Christian church which contains the seat of a bishop, thus serving as the central church of a diocese, conference, or episcopate. The counterpart term for such a church in German is "Dom" from Latin "domus ecclesiae" or "domus episcopalis"; also Italian Duomo, Dutch "Domkerk" and cognates in many other European languages. Churches with the function of "cathedral" are usually specific to those Christian denominations with an episcopal hierarchy, such as the Roman Catholic, Anglican, Orthodox, and some Lutheran and Methodist churches. Church buildings embodying the functions of a cathedral first appear in Italy, Gaul, Spain and North Africa in the 4th century, but cathedrals did not become universal within the Western Catholic Church until the 12th century, by which time they had developed architectural forms, institutional structures and legal identities distinct from parish churches, monastic churches and episcopal residences. - The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with more than 1.27billion members worldwide. As one of the oldest religious institutions in the world, it has played a prominent role in the history of Western civilisation. Headed by the Bishop of Rome, known as the pope, its doctrines are summarised in the Nicene Creed. The Catholic Church is notable within Western Christianity for its sacred tradition and seven sacraments. - The Shanghai Metro is a rapid transit system in Shanghai, China, operating urban and suburban rail transit services to 13 of its 16 municipal districts (except Fengxian, Jinshan and Chongming) and to Huaqiao Town, Kunshan, Jiangsu Province. Opening in 1993 with full-scale construction extending back to 1986, Shanghai Metro is the third oldest rapid transit system in China, after the Beijing Subway and the Tianjin Metro. It has seen substantial growth, significantly during the years leading up to the 2010 Shanghai World Expo, and is still expanding, with its most recent expansions having opened in . It is the largest component of the Shanghai metropolitan rail transit network, together with the Shanghai Maglev Train, the Zhangjiang Tram and the China Railway-operated commuter rail services to Jinshan and to Lingang New City in Pudong. The metro system is also heavily tied with other forms of public transport in Shanghai. - The Roman Catholic Diocese of Shanghai is an ecclesiastical territory or diocese of the Roman Catholic Church in the Municipality of Shanghai, China. It was erected on December 13, 1933 as the Apostolic Vicariate of Shanghai by Pope Pius XI, and was later elevated to the rank of a diocese on April 11, 1946 by Pope Pius XII. The diocese is a suffragan of the Archdiocese of Nanking. - Xujiahui, also spelt Zikawei or Ziccawei from Shanghainese, is a locality in Shanghai, China. It is a historic area of commerce and culture administratively within Xuhui District, which is named after the locality. The area is a well-known precinct for shopping and entertainment in Shanghai. It is served by the Xujiahui Station of the Shanghai Metro. - The word diocese is derived from the Greek term "" meaning "administration". When now used in an ecclesiastical sense, it refers to a territorial unit of administration. In the Western Church, the district is under the supervision of a bishop (who may have assistant bishops to help him or her) and is divided into parishes under the care of priests; but in the Eastern Church, the word denotes the area under the jurisdiction of a patriarch and the bishops under his jurisdiction administer parishes. This structure of church governance is known as episcopal polity. - A parish is a church territorial unit constituting a division within a diocese. A parish is under the pastoral care and clerical jurisdiction of a parish priest, who might be assisted by one or more curates, and who operates from a parish church. Historically, a parish often covered the same geographical area as a manor (its association with the parish church remaining paramount). - Europe is a continent that comprises the westernmost part of Eurasia. Europe is bordered by the Arctic Ocean to the north, the Atlantic Ocean to the west, and the Mediterranean Sea to the south. To the east and southeast, Europe is generally considered as separated from Asia by the watershed divides of the Ural and Caucasus Mountains, the Ural River, the Caspian and Black Seas, and the waterways of the Turkish Straits. Yet the non-oceanic borders of Europea concept dating back to classical antiquityare arbitrary. The primarily physiographic term "continent" as applied to Europe also incorporates cultural and political elements whose discontinuities are not always reflected by the continent's current overland boundaries. - St. Ignatius Cathedral , Shanghai ( ) , also referred to as Xujiahui Cathedral ( ) , is a Neo-Gothic Roman Catholic cathedral , located in Xujiahui , in Shanghai , China .

Before his election to the papacy, Pacelli served as secretary of the Department of Extraordinary Ecclesiastical Affairs, papal nuncio to Germany (19171929), and Cardinal Secretary of State, in which capacity he worked to conclude treaties with European and Latin American nations, most notably the "Reichskonkordat" with Nazi Germany, with which most historians believe the Vatican sought to protect the Church in Germany while Adolf Hitler sought the destruction of "political Catholicism". A pre-war critic of Nazism, Pius XII lobbied world leaders to avoid war and, as Pope at the outbreak of war, issued "Summi Pontificatus", expressing dismay at the invasion of Poland, reiterating Church teaching against racial persecution and calling for love, compassion and charity to prevail over war. - Duomo is a term for an Italian cathedral church.
