Question: When did marriage become a sacrament in the church of the denomination most predominant in Cameroon's main ally?

full_context: Document 1: Sacrament: The Catholic Church recognises seven sacraments: Baptism, Reconciliation (Penance or Confession), Eucharist (or Holy Communion), Confirmation, Marriage, Holy Orders, and Anointing of the Sick. The Eastern Orthodox Church and Oriental Orthodox Church also believe that there are seven major sacraments, but apply the corresponding Greek word, μυστήριον (mysterion) also to rites that in the Western tradition are called sacramentals and to other realities, such as the Church itself. Many Protestant denominations, such as those within the Reformed tradition, identify two sacraments instituted by Christ, the Eucharist (or Holy Communion) and Baptism. The Lutheran sacraments include these two, often adding Confession (and Absolution) as a third sacrament. Anglican and Methodist teaching is that ``there are two Sacraments ordained of Christ our Lord in the Gospel, that is to say, Baptism and the Supper of the Lord '', and that`` those five commonly called Sacraments, that is to say, Confirmation, Penance, Orders, Matrimony, and Extreme Unction, are not to be counted for Sacraments of the Gospel''. In the Community of Christ, a restorationist denomination with traditional Protestant theology, eight sacraments are recognized, including ``baptism, confirmation, blessing of children, the Lord's Supper, ordination, marriage, the Evangelist Blessing, and administration to the sick. ''
Document 2: Paris: During the Middle Ages, Paris was a center of Jewish learning with famous Talmudic scholars, such as Yechiel of Paris who took part in the Disputation of Paris between Christian and Jewish intellectuals. The Parisian Jewish community was victim of persecution, alternating expulsions and returns, until France became the first country in Europe to emancipate its Jewish population during the French Revolution. Although 75% of the Jewish population in France survived the Holocaust during World War II, half the city's Jewish population perished in Nazi concentration camps, while some others fled abroad. A large migration of North Africa Sephardic Jews settled Paris in the 1960s, and represent most of the Paris Jewish community today. There are currently 83 synagogues in the city; The Marais-quarter Agoudas Hakehilos Synagogue, built in 1913 by architect Hector Guimard, is a Paris landmark.
Document 3: Paris: Almost all Protestant denominations are represented in Paris, with 74 evangelical churches from various denominations, including 21 parishes of the United Protestant Church of France and two parishes of the Church of Jesus Christ of the Latter-Day Saints. There are several important churches for the English-speaking community: the American Church in Paris, founded in 1814, was the first American church outside the United States; the current church was finished in 1931. The Saint George's Anglican Church in the 16th arrondissement is the principal Anglican church in the city.
Document 4: Middle Ages: In the 13th century mendicant orders—the Franciscans and the Dominicans—who swore vows of poverty and earned their living by begging, were approved by the papacy. Religious groups such as the Waldensians and the Humiliati also attempted to return to the life of early Christianity in the middle 12th and early 13th centuries, but they were condemned as heretical by the papacy. Others joined the Cathars, another heretical movement condemned by the papacy. In 1209, a crusade was preached against the Cathars, the Albigensian Crusade, which in combination with the medieval Inquisition, eliminated them.
Document 5: Namibia: Namibia follows a largely independent foreign policy, with persisting affiliations with states that aided the independence struggle, including Cuba. With a small army and a fragile economy, the Namibian Government's principal foreign policy concern is developing strengthened ties within the Southern African region. A dynamic member of the Southern African Development Community, Namibia is a vocal advocate for greater regional integration. Namibia became the 160th member of the UN on 23 April 1990. On its independence it became the fiftieth member of the Commonwealth of Nations.
Document 6: Nigeria: Nigeria's foreign policy was tested in the 1970s after the country emerged united from its own civil war. It supported movements against white minority governments in the Southern Africa sub-region. Nigeria backed the African National Congress (ANC) by taking a committed tough line with regard to the South African government and their military actions in southern Africa. Nigeria was also a founding member of the Organisation for African Unity (now the African Union), and has tremendous influence in West Africa and Africa on the whole. Nigeria has additionally founded regional cooperative efforts in West Africa, functioning as standard-bearer for the Economic Community of West African States (ECOWAS) and ECOMOG, economic and military organisations, respectively.
Document 7: Protestantism: A Protestant baptism is held to be valid by the Catholic Church if given with the trinitarian formula and with the intent to baptize. However, as the ordination of Protestant ministers is not recognized due to the lack of apostolic succession and the disunity from Catholic Church, all other sacraments (except marriage) performed by Protestant denominations and ministers are not recognized as valid. Therefore, Protestants desiring full communion with the Catholic Church are not re-baptized (although they are confirmed) and Protestant ministers who become Catholics may be ordained to the priesthood after a period of study.
Document 8: Paris: Like the rest of France, Paris has been predominantly Roman Catholic since the early Middle Ages, though religious attendance is now low. A majority of Parisians are still nominally Roman Catholic. According to 2011 statistics, there are 106 parishes and curates in the city, plus separate parishes for Spanish, Polish and Portuguese Catholics. There are an additional 10 Eastern Orthodox parishes, and bishops for the Armenian and Ukrainian Orthodox Churches. In addition there are eighty male religious orders and 140 female religious orders in the city, as well as 110 Catholic schools with 75,000 students.
Document 9: Ministry of Defence (United Kingdom): The MoD has since been regarded as a leader in elaborating the post-Cold War organising concept of "defence diplomacy". As a result of the Strategic Defence and Security Review 2010, Prime Minister David Cameron signed a 50-year treaty with French President Nicolas Sarkozy that would have the two countries co-operate intensively in military matters. The UK is establishing air and naval bases in the Persian Gulf, located in the UAE and Bahrain. A presence in Oman is also being considered.
Document 10: Marriage in the Catholic Church: With the development of sacramental theology, marriage was included in the select seven to which the term ``sacrament ''was applied. Explicit classification of marriage in this way came in reaction to the contrary teaching of Catharism that marriage and procreation are evil: the first official declaration that marriage is a sacrament was made at the 1184 Council of Verona as part of a condemnation of the Cathars. In 1208, Pope Innocent III required members of another religious movement, that of the Waldensians, to recognize that marriage is a sacrament as a condition for being received back into the Catholic Church. In 1254, Catholics accused Waldensians of condemning the sacrament of marriage,`` saying that married persons sin mortally if they come together without the hope of offspring''. The Fourth Lateran Council of 1215 had already stated in response to the teaching of the Cathars: ``For not only virgins and the continent but also married persons find favour with God by right faith and good actions and deserve to attain to eternal blessedness. ''Marriage was also included in the list of the seven sacraments at the Second Council of Lyon in 1274 as part of the profession of faith required of Michael VIII Palaiologos. The sacraments of marriage and holy orders were distinguished as sacraments that aim at the`` increase of the Church'' from the other five sacraments, which are intended for the spiritual perfection of individuals. The Council of Florence in 1439 again recognised marriage as a sacrament.
Document 11: Imperialism: In World War II, Charles de Gaulle and the Free French used the overseas colonies as bases from which they fought to liberate France. However after 1945 anti-colonial movements began to challenge the Empire. France fought and lost a bitter war in Vietnam in the 1950s. Whereas they won the war in Algeria, the French leader at the time, Charles de Gaulle, decided to grant Algeria independence anyway in 1962. Its settlers and many local supporters relocated to France. Nearly all of France's colonies gained independence by 1960, but France retained great financial and diplomatic influence. It has repeatedly sent troops to assist its former colonies in Africa in suppressing insurrections and coups d’état.
Document 12: Cameroon: Its foreign policy closely follows that of its main ally, France (one of its former colonial rulers). Cameroon relies heavily on France for its defence, although military spending is high in comparison to other sectors of government.President Biya has engaged in a decades-long clash with the government of Nigeria over possession of the oil-rich Bakassi peninsula. Cameroon and Nigeria share a 1,000-mile (1 600 km) border and have disputed the sovereignty of the Bakassi peninsula. In 1994 Cameroon petitioned the International Court of Justice to resolve the dispute. The two countries attempted to establish a cease-fire in 1996, however, fighting continued for years. In 2002, the ICJ ruled that the Anglo-German Agreement of 1913 gave sovereignty to Cameroon. The ruling called for a withdrawal by both countries and denied the request by Cameroon for compensation due to Nigeria's long-term occupation. By 2004, Nigeria had failed to meet the deadline to handover the peninsula. A UN-mediated summit in June 2006 facilitated an agreement for Nigeria to withdraw from the region and both leaders signed the Greentree Agreement. The withdrawal and handover of control was completed by August 2006.
Document 13: Casti connubii: Casti connubii (Latin: "of chaste wedlock") was a papal encyclical promulgated by Pope Pius XI on 31 December 1930 in response to the Lambeth Conference of the Anglican church. It stressed the sanctity of marriage, prohibited Catholics from using any form of artificial birth control, and reaffirmed the prohibition on abortion. It also explained the authority of Church doctrine on moral matters, and advocated that civil governments follow the lead of the Church in this area.
Document 14: Paris: By the end of the 12th century, Paris had become the political, economic, religious, and cultural capital of France. The Île de la Cité was the site of the royal palace. In 1163, during the reign of Louis VII, Maurice de Sully, bishop of Paris, undertook the construction of the Notre Dame Cathedral at its eastern extremity. The Left Bank was the site of the University of Paris, a corporation of students and teachers formed in the mid-12th century to train scholars first in theology, and later in canon law, medicine and the arts.
Document 15: Alsace: Most of the Alsatian population is Roman Catholic, but, largely because of the region's German heritage, a significant Protestant community also exists: today, the EPCAAL (a Lutheran church) is France's second largest Protestant church, also forming an administrative union (UEPAL) with the much smaller Calvinist EPRAL. Unlike the rest of France, the Local law in Alsace-Moselle still provides for to the Napoleonic Concordat of 1801 and the organic articles, which provides public subsidies to the Roman Catholic, Lutheran, and Calvinist churches, as well as to Jewish synagogues; religion classes in one of these faiths is compulsory in public schools. This divergence in policy from the French majority is due to the region having been part of Imperial Germany when the 1905 law separating the French church and state was instituted (for a more comprehensive history, see: Alsace-Lorraine). Controversy erupts periodically on the appropriateness of this legal disposition, as well as on the exclusion of other religions from this arrangement.
