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.
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.
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.
