Christianity is an Abrahamic monotheistic religion based on the life and teachings of Jesus. It is the world's largest and most widespread religion with roughly 2.4 billion followers, comprising around 31.2% of the world population. Its adherents, known as Christians, are estimated to make up a majority of the population in 157 countries and territories. Christians believe that Jesus is the Son of God, whose coming as the Messiah was prophesied in the Hebrew Bible and chronicled in the New Testament.
Christendom historically refers to the Christian states, Christian empires, Christian-majority countries and the countries in which Christianity dominates, prevails, or that it is culturally or historically intertwined with.
Western Europe is the western region of Europe. The region's extent varies depending on context.
Eastern Christianity comprises Christian traditions and church families that originally developed during classical and late antiquity in Western Asia, Asia Minor, Eastern Europe, Southeastern Europe, the Caucasus, Northeast Africa, the Fertile Crescent and the Malabar coast of South Asia, and ephemerally parts of Persia, Central Asia and the Far East. The term does not describe a single communion or religious denomination.
Greek Orthodox Church is a Christian term that can refer to any one of three classes of church, each associated in some way with Greek Christianity or the Eastern Roman Empire.
In ecclesiology, the Christian Church is what different Christian denominations conceive of as being the true body of Christians or the original institution established by Jesus. "Christian Church" has also been used in academia as a synonym for Christianity, despite the fact that it is composed of multiple churches or denominations, many of which hold a doctrinal claim of being the "one true church", to the exclusion of the others.
A Christian denomination is a distinct religious body within Christianity that comprises all church congregations of the same kind, identifiable by traits such as a name, particular history, organization, leadership, theological doctrine, worship style and, sometimes, a founder. It is a secular and neutral term, generally used to denote any established Christian church. Unlike a cult or sect, a denomination is usually seen as part of the Christian religious mainstream. Most Christian denominations refer to themselves as churches, whereas some newer ones tend to interchangeably use the terms churches, assemblies, fellowships, etc. Divisions between one group and another are defined by authority and doctrine; issues such as the nature of Jesus, the authority of apostolic succession, biblical hermeneutics, theology, ecclesiology, eschatology, and papal primacy may separate one denomination from another. Groups of denominations—often sharing broadly similar beliefs, practices, and historical ties—are sometimes known as "branches of Christianity". These branches differ in many ways, especially through differences in practices and belief.
Christianity is the largest religion in Germany. It was introduced to the area of modern Germany by 300 AD, while parts of that area belonged to the Roman Empire, and later, when Franks and other Germanic tribes converted to Christianity from the fifth century onwards. The area became fully Christianized by the time of Charlemagne in the eighth and ninth century. After the Reformation started by Martin Luther in the early 16th century, many people left the Catholic Church and became Protestant, mainly Lutheran and Calvinist. In the 17th and 18th centuries, German cities also became hubs of heretical and sometimes anti-religious freethinking, challenging the influence of religion and contributing to the spread of secular thinking about morality across Germany and Europe.
Christianity in Albania was established throughout the country in 325 AD. From 1100 AD, the Roman Empire carried out Church missions in the area. In relation to the increasing influence of Venice, the Franciscans started to settle down in the area in the 13th century. From the 15th century to the 19th century, under the rule of the Ottoman Empire, Christianity was replaced by Islam as the majority religion in Albania during the Ottoman Empire.
The Western religions are the religions that originated within Western culture, which are thus historically, culturally, and theologically distinct from Eastern, African and Iranian religions. The term Abrahamic religions is often used instead of using the East and West terminology, as these originated in the Middle East.
Religion has been a major influence on the societies, cultures, traditions, philosophies, artistic expressions and laws within present-day Europe. The largest religion in Europe is Christianity. However, irreligion and practical secularisation are also prominent in some countries. In Southeastern Europe, three countries have Muslim majorities, with Christianity being the second-largest religion in those countries. Ancient European religions included veneration for deities such as Zeus. Modern revival movements of these religions include Heathenism, Rodnovery, Romuva, Druidry, Wicca, and others. Smaller religions include Indian religions, Judaism, and some East Asian religions, which are found in their largest groups in Britain, France, and Kalmykia.
As of 2011, most Armenians in Armenia are Christians (97%) and are members of the Armenian Apostolic Church, which is one of the oldest Christian churches. It was founded in the 1st century AD, and in 301 AD became the first branch of Christianity to become a state religion.
Religion in Bulgaria has been dominated by Christianity since its adoption as the state religion in 864. The dominant form of the religion is Eastern Orthodox Christianity within the fold of the Bulgarian Orthodox Church. During the Ottoman rule of the Balkans, Islam spread to the territories of Bulgaria, and it remains a significant minority today. The Catholic Church has roots in the country since the Middle Ages, and Protestantism arrived in the 19th century; both of them remain very small minorities. Today, a significant part of the Bulgarians are not religious, or believers who do not identify with any specific religion, and Bulgaria has been the cradle of some new religions, notably the Neo-Theosophical movement of Dunovism.
Christianity in Myanmar has a history dating to the early 18th century. According to the 2016 census, Christianity is the country's second largest religion, practiced by 6.3% of the population, primarily among the Kachin, Chin and Kayin, and Eurasians because of missionary work in their respective areas. In 2023, almost 8% of the population is Christian; about two-thirds of the country's Christians are Protestants, in particular Baptists of the Myanmar Baptist Convention. One in six Christians are Roman Catholics.
Christianity is the second largest religion in Egypt. The vast majority of Egyptian Christians are Copts. As of 2019, Copts in Egypt make up approximately 10 percent of the nation's population, with an estimated population of 9.5 million or 10 million. In 2018, approximately 90% of Egyptian Christians were Coptic Orthodox.
Christianity is a minority religion in Yemen. The Yemeni constitution mentions religious liberty. There are three churches in Aden.
Christianity in Turkey has a long history dating back to the early origins of Christianity in Asia Minor during the 1st century AD. In modern times the percentage of Christians in Turkey has declined from 20 to 25 percent in 1914 to 3–5.5 percent in 1927, to 0.3–0.4%, roughly translating to 200,000–320,000 devotees. The percentage of Christians in Turkey fell mainly as a result of the late Ottoman genocides: the Armenian genocide, Greek genocide, and Assyrian genocide, the population exchange between Greece and Turkey, the emigration of Christians that began in the late 19th century and gained pace in the first quarter of the 20th century, and due to events such as the 1942 Varlık Vergisi tax levied on non-Muslim citizens in Turkey and the 1955 Istanbul pogrom against Greek and Armenian Christians. Exact numbers are difficult to estimate as many former Muslim converts to Christianity often hide their Christian faith for fear of familial pressure, religious discrimination, and persecution.
Religion in South America has been a major influence on art, culture, philosophy and law and changed greatly in recent years. Roman Catholicism has rapidly declined. Most of this is due to the growth of Protestantism, particularly evangelical Christians. A smaller number of South Americans are also beginning to identify as irreligious. Sizeable adherents of other religions are also present, including of various indigenous religions.
The Western world, also known as the West, primarily refers to various nations and states in the regions of Australasia, Western Europe, and Northern America; with some debate as to whether Eastern Europe and Latin America also constitute the West. The Western world likewise is called the Occident in contrast to the Eastern world known as the Orient. The West is considered an evolving concept; made up of cultural, political, and economic synergy among diverse groups of people, and not a rigid region with fixed borders and members. Definitions of "Western world" vary according to context and perspectives.
Christian culture generally includes all the cultural practices which have developed around the religion of Christianity. There are variations in the application of Christian beliefs in different cultures and traditions.
