Postchristianity is the situation in which Christianity is no longer the dominant civil religion of a society but has gradually assumed values, culture, and worldviews that are not necessarily Christian. Post-Christian tends to refer to the loss of Christianity's monopoly in historically Christian societies to atheism or secularism. It does not include formerly Christian-majority societies that now follow other religions such as Islam. Some scholars have disputed the global decline of Christianity, and instead hypothesized an evolution of Christianity, which allows it not only to survive but actively to expand its influence in contemporary societies. Historically, the majority of Christians have lived in Western nations, once called Christendom, and often conceptualized as "European Christian" civilization. A post-Christian society is one in which Christianity is no longer the dominant civil religion but that has gradually assumed values, culture, and worldviews that are not necessarily Christian (and also may not necessarily reflect any world religion's standpoint or may represent a combination of either several religions or none). Post-Christian tends to refer to the loss of Christianity's monopoly, if not its followers, in historically Christian societies. Post-Christian societies are found across the Global North/West: for example, though the 2005 Eurobarometer survey indicated that the majority of Europeans hold some form of belief in a higher power (see also "Ietsism"); fewer point explicitly to the Christian God. Despite this decline, Christianity remains the dominant religion in Europe, the Americas and Oceania. According to a 2010 study by the Pew Research Center, 76% of the population of Europe, 77% of North America and 90% of Latin America and the Caribbean identified themselves as Christians. In his 1961 book The Death of God, the French theologian Gabriel Vahanian argued that modern secular culture in most of Western civilization had lost all sense of the sacred, lacked any sacramental meaning, and disdained any transcendental purpose or sense of providence, bringing him to the conclusion that for the modern mind, "God is dead".
