full_context: Document 1: Nero Burning ROM: Nero Burning ROM is a pun in reference to Roman Emperor Nero, who was best known for his association in the Great Fire of Rome. The emperor allegedly fiddled while the city of Rome burned. Also, Rome in German is spelled Rom. The software's logo features a burning Colosseum, although this is an anachronism as it was not built until after Nero's death.
Document 2: Religion in ancient Rome: Prodigies were transgressions in the natural, predictable order of the cosmos – signs of divine anger that portended conflict and misfortune. The Senate decided whether a reported prodigy was false, or genuine and in the public interest, in which case it was referred to the public priests, augurs and haruspices for ritual expiation. In 207 BC, during one of the Punic Wars' worst crises, the Senate dealt with an unprecedented number of confirmed prodigies whose expiation would have involved "at least twenty days" of dedicated rites.
Document 3: Protestantism: Today, Lutheranism is one of the largest branches of Protestantism. With approximately 80 million adherents, it constitutes the third most common Protestant confession after historically Pentecostal denominations and Anglicanism. The Lutheran World Federation, the largest global communion of Lutheran churches represents over 72 million people. Additionally, there are also many smaller bodies such as the International Lutheran Council and the Confessional Evangelical Lutheran Conference, as well as independent churches.
Document 4: Religion in ancient Rome: In 380, under Theodosius I, Nicene Christianity became the official state religion of the Roman Empire. Christian heretics as well as non-Christians were subject to exclusion from public life or persecution, though Rome's original religious hierarchy and many aspects of its ritual influenced Christian forms, and many pre-Christian beliefs and practices survived in Christian festivals and local traditions.
Document 5: Christianity in the United States: All Protestant denominations accounted for 51.3%, while the Catholic Church by itself, at 23.9%, was the largest individual denomination. A 2008 Pew study categorizes white evangelical Protestants, 26.3% of the population, as the country's largest religious cohort; another study in 2004 estimates evangelical Protestants of all races at 30 -- 35%. The nation's second - largest church and the single largest Protestant denomination is the Southern Baptist Convention. The United Methodist Church is the third largest church and the largest mainline Protestant denomination in the United States. The Church of Jesus Christ of Latter - day Saints (Mormons) is the fourth - largest church in the United States and the largest church originating in the U.S. The Church of God in Christ is the fifth - largest denomination, the largest Pentecostal church, and the largest traditionally African - American denomination in the nation. Among Eastern Christian denominations, there are several Eastern Orthodox and Oriental Orthodox churches, with just below 1 million adherents in the US, or 0.4% of the total population.
Document 6: Protestantism: There are more than 900 million Protestants worldwide,[ad] among approximately 2.4 billion Christians.[ae] In 2010, a total of more than 800 million included 300 million in Sub-Saharan Africa, 260 million in the Americas, 140 million in Asia-Pacific region, 100 million in Europe and 2 million in Middle East-North Africa. Protestants account for nearly forty percent of Christians worldwide and more than one tenth of the total human population. Various estimates put the percentage of Protestants in relation to the total number of world's Christians at 33%, 36%, 36.7%, and 40%, while in relation to the world's population at 11.6% and 13%.
Document 7: Protestantism: In Europe, there has been a general move away from religious observance and belief in Christian teachings and a move towards secularism. The Enlightenment is largely responsible for the spread of secularism. Several scholars have argued for a link between the rise of secularism and Protestantism, attributing it to the wide-ranging freedom in the Protestant countries. In North America, South America and Australia Christian religious observance is much higher than in Europe. United States remains particularly religious in comparison to other developed countries. South America, historically Roman Catholic, has experienced a large Evangelical and Pentecostal infusion in the 20th and 21st centuries.
Document 8: Africa: Africans profess a wide variety of religious beliefs, and statistics on religious affiliation are difficult to come by since they are often a sensitive topic for governments with mixed religious populations. According to the World Book Encyclopedia, Islam is the largest religion in Africa, followed by Christianity. According to Encyclopædia Britannica, 45% of the population are Christians, 40% are Muslims, and 10% follow traditional religions. A small number of Africans are Hindu, Buddhist, Confucianist, Baha'i, or Jewish. There is also a minority of people in Africa who are irreligious.
Document 9: Religion in ancient Rome: Constantine's nephew Julian rejected the "Galilean madness" of his upbringing for an idiosyncratic synthesis of neo-Platonism, Stoic asceticism and universal solar cult. Julian became Augustus in 361 and actively but vainly fostered a religious and cultural pluralism, attempting a restitution of non-Christian practices and rights. He proposed the rebuilding of Jerusalem's temple as an Imperial project and argued against the "irrational impieties" of Christian doctrine. His attempt to restore an Augustan form of principate, with himself as primus inter pares ended with his death in 363 in Persia, after which his reforms were reversed or abandoned. The empire once again fell under Christian control, this time permanently.
Document 10: Christian: Today, about 37% of all Christians live in the Americas, and about 26% live in Europe, 24% of total Christians live in sub-Saharan Africa, about 13% in Asia and the Pacific, and 1% of the world's Christians live in the Middle east and North Africa. About half of all Christians worldwide are Catholic, while more than a third are Protestant (37%). Orthodox communions comprise 12% of the world's Christians. Other Christian groups make up the remainder. Christians make up the majority of the population in 158 countries and territories. 280 million Christian live as a minority.
Document 11: Greeks: Of the new eastern religions introduced into the Greek world, the most successful was Christianity. From the early centuries of the Common Era, the Greeks identified as Romaioi ("Romans"), by that time the name ‘Hellenes’ denoted pagans. While ethnic distinctions still existed in the Roman Empire, they became secondary to religious considerations and the renewed empire used Christianity as a tool to support its cohesion and promoted a robust Roman national identity. Concurrently the secular, urban civilization of late antiquity survived in the Eastern Mediterranean along with Greco-Roman educational system, although it was from Christianity that the culture's essential values were drawn.
Document 12: Diocletianic Persecution: The Diocletianic or Great Persecution was the last and most severe persecution of Christians in the Roman Empire. In 303, the Emperors Diocletian, Maximian, Galerius, and Constantius issued a series of edicts rescinding the legal rights of Christians and demanding that they comply with traditional Roman religious practices. Later edicts targeted the clergy and ordered all inhabitants to sacrifice to the Roman gods (a policy known as universal sacrifice). The persecution varied in intensity across the empire -- weakest in Gaul and Britain, where only the first edict was applied, and strongest in the Eastern provinces. Persecutory laws were nullified by different emperors at different times, but Constantine and Licinius's Edict of Milan (313) has traditionally marked the end of the persecution.
Document 13: Christian: As of the early 21st century, Christianity has approximately 2.4 billion adherents. The faith represents about a third of the world's population and is the largest religion in the world. Christians have composed about 33 percent of the world's population for around 100 years. The largest Christian denomination is the Roman Catholic Church, with 1.17 billion adherents, representing half of all Christians.
Document 14: Religion in ancient Rome: After the Great Fire of Rome in 64 AD, Emperor Nero accused the Christians as convenient scapegoats, who were later persecuted and killed. From that point on, Roman official policy towards Christianity tended towards persecution. During the various Imperial crises of the 3rd century, “contemporaries were predisposed to decode any crisis in religious terms”, regardless of their allegiance to particular practices or belief systems. Christianity drew its traditional base of support from the powerless, who seemed to have no religious stake in the well-being of the Roman State, and therefore threatened its existence. The majority of Rome’s elite continued to observe various forms of inclusive Hellenistic monism; Neoplatonism in particular accommodated the miraculous and the ascetic within a traditional Graeco-Roman cultic framework. Christians saw these ungodly practices as a primary cause of economic and political crisis.
Document 15: Constantine the Great and Christianity: During the reign of the Roman Emperor Constantine the Great (306 -- 337 AD), Christianity began to transition to the dominant religion of the Roman Empire. Historians remain uncertain about Constantine's reasons for favoring Christianity, and theologians and historians have often argued about which form of Early Christianity he subscribed to. There is no consensus among scholars as to whether he adopted his mother Helena's Christianity in his youth, or, as claimed by Eusebius, encouraged her to convert to the faith himself. Some scholars question the extent to which he should be considered a Christian emperor: ``Constantine saw himself as an 'emperor of the Christian people'. If this made him a Christian is the subject of... debate, ''although he allegedly received a baptism shortly before his death.
