In Protestant theology, Jesus' death is regarded as a substitutionary penalty carried by Jesus, for the debt that has to be paid by humankind when it broke God's moral law. Christians differ in their views on the extent to which individuals' salvation is pre-ordained by God.

Protestant interpretation

Qualities of Scripture

Many Protestant Christians, such as Lutherans and the Reformed, believe in the doctrine of '' sola scriptura''—that the Bible is a self-sufficient revelation, the final authority on all Christian doctrine, and revealed all truth necessary for salvation; other Protestant Christians, such as Methodists and Anglicans, affirm the doctrine of ''

prima scriptura ''Prima scriptura'' is the Christian doctrine that canonized scripture is "first" or "above all" other sources of divine revelation. Implicitly, this view suggests that, besides canonical scripture, there can be other guides for what a believer s ...

'' which teaches that Scripture is the primary source for Christian doctrine, but that "tradition, experience, and reason" can nurture the Christian religion as long as they are in harmony with the Bible. Protestants characteristically believe that ordinary believers may reach an adequate understanding of Scripture because Scripture itself is clear in its meaning (or "perspicuous"). Martin Luther believed that without God's help, Scripture would be "enveloped in darkness". He advocated for "one definite and simple understanding of Scripture".

John Calvin John Calvin (; frm, Jehan Cauvin; french: link=no, Jean Calvin ; 10 July 150927 May 1564) was a French theologian, pastor and reformer in Geneva during the Protestant Reformation. He was a principal figure in the development of the system ...

wrote, "all who refuse not to follow the Holy Spirit as their guide, find in the Scripture a clear light". Related to this is "efficacy", that Scripture is able to lead people to faith; and "sufficiency", that the Scriptures contain everything that one needs to know in order to obtain salvation and to live a Christian life.

Original intended meaning of Scripture

Protestants stress the meaning conveyed by the words of Scripture, the historical-grammatical method. The historical-grammatical method or grammatico-historical method is an effort in Biblical hermeneutics to find the intended original meaning in the text. This original intended meaning of the text is drawn out through examination of the passage in light of the grammatical and syntactical aspects, the historical background, the literary genre, as well as theological (canonical) considerations. The historical-grammatical method distinguishes between the one original meaning and the significance of the text. The significance of the text includes the ensuing use of the text or application. The original passage is seen as having only a single meaning or sense. As Milton S. Terry said: "A fundamental principle in grammatico-historical exposition is that the words and sentences can have but one significance in one and the same connection. The moment we neglect this principle we drift out upon a sea of uncertainty and conjecture". Technically speaking, the grammatical-historical method of interpretation is distinct from the determination of the passage's significance in light of that interpretation. Taken together, both define the term (Biblical) hermeneutics. Some Protestant interpreters make use of typology.

Demographics

With around 2.38 billion adherents according to a 2020 estimation by Pew Research Center,31.4% of ≈7.4 billion world population (under the section 'People') split into three main branches of Catholic, Protestant, and Eastern Orthodox, Christianity is the major religious groups, world's largest religion. High birth rates and Conversion to Christianity, conversions in the global South were cited as the reasons for the Christian population growth. The Christian share of the world's population has stood at around 33% for the last hundred years, which means that one in three persons on Earth are Christians. This masks a major shift in the demographics of Christianity; large increases in the developing world have been accompanied by substantial declines in the developed world, mainly in Western Europe and North America. According to a 2015 Pew Research Center study, within the next four decades, Christianity will remain the largest religion; and by 2050, the Christian population is expected to exceed 3 billion.

According to some scholars, Christianity ranks at first place in net gains through religious conversion. As a percentage of Christians, the

and Orthodoxy (both Eastern Orthodox Church, Eastern and Oriental Orthodoxy, Oriental) are declining in some parts of the world (though Catholicism is growing in Asia, in Africa, vibrant in Eastern Europe, etc.), while Protestants and other Christians are on the rise in the developing world. The so-called ''popular Protestantism''A flexible term, defined as all forms of Protestantism with the notable exception of the historical denominations deriving directly from the Protestant Reformation. is one of the fastest growing religious categories in the world. Nevertheless, Catholicism will also continue to grow to 1.63 billion by 2050, according to Todd Johnson of the Center for the Study of Global Christianity. Africa alone, by 2015, will be home to 230 million African Catholics. And if in 2018, the U.N. projects that Africa's population will reach 4.5 billion by 2100 (not 2 billion as predicted in 2004), Catholicism will indeed grow, as will other religious groups. According to Pew Research Center, Africa is expected to be home to 1.1 billion Christianity in Africa, African Christians by 2050. In 2010, 87% of the world's Christian population lived in countries where Christians are in the majority, while 13% of the world's Christian population lived in countries where Christians are in the minority. Christianity is the predominant religion in Europe, the Americas, Oceania, and Sub-Saharan Africa. There are also large Christian communities in other parts of the world, such as Central Asia, the Middle East and North Africa,

, Southeast Asia, and the Indian subcontinent. In Asia, it is the dominant religion in Armenia, Cyprus, Georgia, East Timor, and the Philippines. However, it is declining in some areas including the northern and western United States, some areas in Oceania (Australia and New ZealandTable 28, 2006 Census Data – QuickStats About Culture and Identity – Tables
), northern Europe (including Great Britain, Scandinavia and other places), France, Germany, and the Canadian provinces of Ontario, British Columbia, and Quebec, and some parts of Asia (especially the Middle East, due to the Christian emigration, and Macau). The Christian population is not decreasing in Brazil, the southern United States, and the province of Alberta, Canada, but the percentage is decreasing. Since the fall of communism, the proportion of Christians has been stable or even increased in the Central Europe, Central and Eastern European countries. Christianity is growing rapidly in both numbers and percentage in China, other Asian countries, Sub-Saharan Africa,The Next Christendom: The Rise of Global Christianity. New York: Oxford University Press. 2002. 270 pp. Latin America, Eastern Europe,

(Maghreb), Gulf Cooperation Council countries, and Oceania. Despite a decline in adherence in the

, Christianity remains the dominant religion in the region, with about 70% of that population identifying as Christian. Christianity remains the largest religion in Western Europe, where 71% of Western Europeans identified themselves as Christian in 2018. A 2011 Pew Research Center survey found that 76% of Europeans, 73% in Oceania and about 86% in the Americas (90% in Latin America and 77% in North America) identified themselves as Christians. By 2010 about 157 countries and territories in the world had Christianity by country, Christian majorities. However, there are many charismatic movements that have become well established over large parts of the world, especially Africa, Latin America, and Asia. Since 1900, primarily due to conversion, Protestantism has spread rapidly in Africa, Asia, Oceania, and Latin America. From 1960 to 2000, the global growth of the number of reported

grew three times the world's population rate, and twice that of

. According to the historian Geoffrey Blainey from the University of Melbourne, since the 1960s there has been a substantial increase in the number of conversions from Islam to Christianity, mostly to the Evangelical and Pentecostal forms. A study conducted by St. Mary's University estimated about 10.2 million Muslim convert to Christianity, converts to Christianity in 2015; according to the study significant numbers of Muslim converts to Christianity can be found in Afghanistan, Azerbaijan, Central Asia (including Kazakhstan, Kyrgyzstan, and other countries), Indonesia, Malaysia, the Middle East (including Iran, Saudi Arabia, Turkey, and other countries), North Africa (including Algeria, Morocco, and TunisiaInternational Religious Freedom Report 2007: Tunisia
United States Bureau of Democracy, Human Rights and Labor (14 September 2007). ''This article incorporates text from this source, which is in the public domain.''), Sub-Saharan Africa, and the Western World (including Albania, Belgium, France, Germany, Kosovo, the Netherlands, Russia, Scandinavia, United Kingdom, the United States, and other western countries). It is also reported that Christianity is popular among people of different backgrounds in Africa and Asia; according to a report by the Singapore Management University, more people in Southeast Asia are converting to Christianity, many of them young and having a university degree. According to scholar Juliette Koning and Heidi Dahles of Vrije Universiteit Amsterdam there is a "rapid expansion" of Christianity in Singapore, China, Hong Kong, Taiwan, Christianity in Indonesia, Indonesia, Malaysia, and South Korea. According to scholar Terence Chong from the Institute of Southeast Asian Studies, since the 1980s Christianity is expanding in China, Singapore, Indonesia, Christianity in Japan, Japan, Malaysia, Taiwan, South Korea, and Vietnam. In most countries in the developed world, church attendance among people who continue to identify themselves as Christians has been falling over the last few decades. Some sources view this as part of a drift away from traditional membership institutions, while others link it to signs of a decline in belief in the importance of religion in general. Europe's Christian population, though in decline, still constitutes the largest geographical component of the religion. According to data from the 2012 European Social Survey, around a third of Christianity in Europe, European Christians say they attend services once a month or more. Conversely, according to the World Values Survey, about more than two-thirds of Latin American Christians, and about 90% of Christianity in Africa, African Christians (in Ghana, Nigeria, Rwanda, South Africa and Zimbabwe) said they attended church regularly. According to a 2018 study by the Pew Research Center, Christians in Africa and Latin America and the United States have high levels of commitment to their faith. Christian state, Christianity, in one form or another, is the sole

of the following nations: Argentina (Catholic), Costa Rica (Catholic), the Kingdom of Denmark (Lutheran), England (Anglican), Greece (Greek Orthodox), Iceland (Lutheran), Liechtenstein (Catholic), Malta (Catholic), Monaco (Catholic), Norway (Lutheran),Løsere bånd, men fortsatt statskirke

Churches and denominations

Christianity can be taxonomically divided into six main groups: Catholic Church, Roman Catholicism,

, Oriental Orthodox Churches, Oriental Orthodoxy, Eastern Orthodox Church, Eastern Orthodoxy, the

, and Restorationism. A broader distinction that is sometimes drawn is between Eastern Christianity and

, which has its origins in the

(Great Schism) of the 11th century. Recently, neither Western or Eastern World Christianity has also stood out, for example, in African-initiated churches. However, there are other present and historical Christian groups that do not fit neatly into one of these primary categories. There is a diversity of doctrines and Liturgy, liturgical practices among groups calling themselves Christian. These groups may vary ecclesiology, ecclesiologically in their views on a classification of Christian denominations. The Nicene Creed (325), however, is typically accepted as authoritative by most Christians, including the Catholic, Eastern Orthodox, Oriental Orthodox, and major Protestant (such as Lutheran and Anglican) denominations.

Eastern Orthodox Church

The Eastern Orthodox Church consists of those churches in communion with the patriarchal sees of the East, such as the Ecumenical Patriarch of Constantinople.Cross/Livingstone. ''The Oxford Dictionary of the Christian Church'', p. 1199. Like the Catholic Church, the Eastern Orthodox Church also traces its heritage to the foundation of Christianity through apostolic succession and has an Episcopal polity, episcopal structure, though the autocephaly, autonomy of its component parts is emphasized, and most of them are national churches.

Oriental Orthodoxy

The Oriental Orthodoxy, Oriental Orthodox Churches (also called "Old Oriental" churches) are those eastern churches that recognize the first three ecumenical councils—

, and First Council of Ephesus, Ephesus—but reject the dogmatic definitions of the

and instead espouse a Miaphysite christology. The Oriental Orthodox communion consists of six groups: Syriac Orthodox, Coptic Orthodox Church, Coptic Orthodox, Ethiopian Orthodox, Eritrean Orthodox, Malankara Orthodox Syrian Church (India), and Armenian Apostolic churches. These six churches, while being in communion with each other, are completely independent hierarchically. These churches are generally not in communion with the

, with whom they are in dialogue for erecting a communion. Together, they have about 62 million members worldwide. As some of the oldest religious institutions in the world, the Oriental Orthodox Churches have played a prominent role in the history and culture of

, Turkey, Eritrea,

, Christian Nubia, Sudan and parts of the

and India. An Eastern Christian body of Autocephaly, autocephalous Christian denomination, churches, its

s are equal by virtue of episcopal ordination, and its doctrines can be summarized in that the churches recognize the validity of only the first three

s. Some Oriental Orthodox Churches such as the Coptic Orthodox Church, Coptic Orthodox, Ethiopian Orthodox, Eritrean Orthodox, places a heavier emphasis on Old Testament teachings than one might find in other Christian denominations, and its followers adhere to certain practices: following Christian dietary laws, dietary rules that are similar to Jewish Kashrut, require that their male members undergo circumcision, and observes ritual purification.

played a major role in the history of Christianity in Asia. Between the 9th and 14th centuries, it represented the world's largest Christian denomination in terms of geographical extent. It established Dioceses of the Church of the East to 1318, dioceses and communities stretching from the Mediterranean Sea and today's Iraq and Iran, to India (East Syriac ecclesiastical province), India (the Saint Thomas Christians, Saint Thomas Syrian Christians of Kerala), the Christianity among the Mongols, Mongol kingdoms in Central Asia, and Church of the East in China, China during the Tang dynasty (7th–9th centuries). In the 13th and 14th centuries, the church experienced a final period of expansion under the Mongol Empire, where influential Church of the East clergy sat in the Mongol court. The

—in parallel to the Catholic patriarchate established in the 16th century that evolved into the Chaldean Catholic Church, an Eastern Catholic church in full communion with the Pope. It is an Eastern Christian Christian denomination, church that follows the traditional christology and

of the historical Church of the East. Largely Aniconism in Christianity, aniconic and not in communion (Christianity), communion with any other church, it belongs to the eastern branch of Syriac Christianity, and uses the East Syriac Rite in its liturgy. Its main spoken language is Syriac, a dialect of Eastern Aramaic, and the majority of its adherents are ethnic Assyrian people, Assyrians, mostly living in Iran, Iraq,

, Turkey, India (Chaldean Syrian Church), and in the Assyrian diaspora. It is officially headquartered in the city of Erbil in northern Iraqi Kurdistan, and its original area also spreads into south-eastern Turkey and north-western Iran, corresponding to ancient Assyria. Its hierarchy is composed of metropolitan bishops and diocesan bishops, while lower clergy consists of priests and deacons, who serve in dioceses (eparchies) and parishes throughout the Middle East, India, North America, Oceania, and Europe (including the Caucasus and Russia). The Ancient Church of the East distinguished itself from the

It is officially headquartered in the city of Baghdad, Iraq. The majority of its adherents are ethnic Assyrian people, Assyrians.

Protestantism

In 1521, the Edict of Worms condemned

and officially banned citizens of the Holy Roman Empire from defending or propagating his ideas.Fahlbusch, Erwin, and Bromiley, Geoffrey William, ''The Encyclopedia of Christianity, Volume 3''. Grand Rapids, Michigan: Eerdmans, 2003. p. 362. This split within the Roman Catholic church is now called the

. Prominent Reformers included Martin Luther, Huldrych Zwingli, and

. The 1529 Protestation at Speyer against being excommunicated gave this party the name

. Luther's primary theological heirs are known as Lutheranism, Lutherans. Zwingli and Calvin's heirs are far broader denominationally, and are referred to as the Calvinism, Reformed tradition.McManners, ''Oxford Illustrated History of Christianity''. pp. 251–259. Protestants have developed Protestant culture, their own culture, with major contributions in education, the Merton thesis, humanities and sciences, the political and social order, the Protestant work ethic, economy and the arts, and many other fields.Karl Heussi, ''Kompendium der Kirchengeschichte'', 11. Auflage (1956), Tübingen (Germany), pp. 317–319, 325–326 The Anglicanism, Anglican churches descended from the

and organized in the

. Some, but not all Anglicans consider themselves both Protestant and Catholic. Since the Anglican, Lutheran, and the Reformed branches of Protestantism originated for the most part in cooperation with the government, these movements are termed the " Magisterial Reformation". On the other hand, groups such as the Anabaptism, Anabaptists, who often do not consider themselves to be Protestant, originated in the

, which though sometimes protected under ''Acts of Toleration'', do not trace their history back to any state church. They are further distinguished by their rejection of infant baptism; they believe in baptism only of adult believers—credobaptism (Anabaptists include the

, Apostolic Christian Church, Apostolic, Mennonites,

, River Brethren and Schwarzenau Brethren/German Baptist groups.) The term ''Protestant'' also refers to any churches which formed later, with either the Magisterial or Radical traditions. In the 18th century, for example, Methodism grew out of

minister John Wesley's Evangelical Revival, evangelical revival movement. Several Pentecostal and Nondenominational Christianity, non-denominational churches, which emphasize the cleansing power of the

, in turn grew out of Methodism. Because Methodists, Pentecostals and other evangelicals stress "accepting Jesus as your personal Lord and Savior", which comes from Wesley's emphasis of the Born again (Christianity), New Birth, they often refer to themselves as being Born again Christianity, born-again. Protestantism is the second largest major group of Christians after Catholicism by number of followers, although the Eastern Orthodox Church is larger than any single Protestant denomination. Estimates vary, mainly over the question of which denominations to classify as Protestant. Yet, the total number of Protestant Christians is generally estimated between 800 million and 1 billion, corresponding to nearly 40% of the world's Christians. The majority of Protestants are members of just a handful of denominational families, i.e. Adventism, Adventists, Anglicanism, Anglicans,

, Calvinism, Reformed (Calvinists), Lutheranism, Lutherans, Methodists, Moravian Church, Moravians/Hussite Church, Hussites, and Pentecostalism, Pentecostals. Nondenominational Christianity, Nondenominational, Evangelicalism, evangelical, Charismatic Movement, charismatic, Neo-charismatic churches, neo-charismatic, independent, and other churches are on the rise, and constitute a significant part of Protestant Christianity. Some groups of individuals who hold basic Protestant tenets identify themselves as "Christians" or "born-again Christians". They typically distance themselves from the confessionalism (religion), confessionalism and

alism of other Christian communitiesConfessionalism is a term employed by historians to refer to "the creation of fixed identities and systems of beliefs for separate churches which had previously been more fluid in their self-understanding, and which had not begun by seeking separate identities for themselves—they had wanted to be truly Catholic and reformed." (MacCulloch, ''The Reformation: A History'', p. xxiv.) by calling themselves "Non-denominational Christianity, non-denominational" or "evangelical". Often founded by individual pastors, they have little affiliation with historic denominations.

Restorationism

The

, a period of religious revival that occurred in the United States during the early 1800s, saw the development of a number of unrelated churches. They generally saw themselves as Restorationism, restoring the original church of Jesus Christ rather than reforming one of the existing churches. A common belief held by Restorationists was that the other divisions of Christianity had introduced doctrinal defects into Christianity, which was known as the Great Apostasy. In Asia, Iglesia ni Cristo is a known restorationist religion that was established during the early 1900s. Some of the churches originating during this period are historically connected to early 19th-century camp meetings in the Midwest and upstate New York. One of the largest churches produced from the movement is the Church of Jesus Christ of Latter-day Saints. American Millennialism and Adventism, which arose from Evangelical Protestantism, influenced the

movement and, as a reaction specifically to William Miller (preacher), William Miller, the Seventh-day Adventist Church, Seventh-day Adventists. Others, including the Christian Church (Disciples of Christ), Evangelical Christian Church in Canada,

, and the Christian churches and churches of Christ, have their roots in the contemporaneous Stone-Campbell Restoration Movement, which was centered in Kentucky and Tennessee. Other groups originating in this time period include the Christadelphians and the previously mentioned

. While the churches originating in the Second Great Awakening have some superficial similarities, their doctrine and practices vary significantly.

Other

Within Italy, Poland, Lithuania, Transylvania, Hungary, Romania, and the United Kingdom, Unitarianism, Unitarian Churches emerged from the Reformed tradition, Reformed tradition in the 16th century; the Unitarian Church of Transylvania is an example of such a denomination that arose in this era. They adopted the Anabaptist doctrine of credobaptism. Various smaller Independent Catholic communities, such as the Old Catholic Church, include the word ''Catholic (term), Catholic'' in their title, and arguably have more or less liturgical practices in common with the Catholic Church, but are no longer in full communion with the Holy See. Spiritual Christians, such as the Doukhobors and Molokans, broke from the Russian Orthodox Church and maintain close association with Mennonites and Quakers due to similar religious practices; all of these groups are furthermore collectively considered to be peace churches due to their belief in Christian pacifism, pacifism. Messianic Judaism (or the Messianic Movement) is the name of a Christian movement comprising a number of streams, whose members may consider themselves Jewish. The movement originated in the 1960s and 1970s, and it blends elements of religious Jewish practice with evangelical Christianity. Messianic Judaism affirms Christian creeds such as the messiahship and divinity of "Yeshua" (the Hebrew name of Jesus) and the Triune Nature of God, while also adhering to some Jewish dietary laws and customs. Esoteric Christianity, Esoteric Christians, such as The Christian Community, regard Christianity as a Western esotericism, mystery religion and profess the existence and possession of certain Esotericism, esoteric doctrines or practices, hidden from the public and accessible only to a narrow circle of "enlightened", "initiated", or highly educated people. Nondenominational Christianity or non-denominational Christianity consists of Simple church, churches which typically distance themselves from the confessionalism (religion), confessionalism or

alism of other Christian communities by not formally aligning with a specific Christian denomination. Nondenominational Christianity first arose in the 18th century through the Stone-Campbell Restoration Movement, with followers organizing themselves as "Christians (Stone Movement), Christians" and "Disciples of Christ (Campbell Movement), Disciples of Christ", but many typically adhere to evangelical Christianity.

Since the spread of Christianity from the

) and Archdiocese of Carthage, Carthage, whose communities were called Western or Latin Christendom, and

(Eastern Christianity), Antioch (Syriac Christianity), Kerala (Saint Thomas Christians, Indian Christianity) and Alexandria (Coptic Christianity), whose communities were called Eastern or Oriental Christendom. The

was one of the peaks in Christian history and Eastern Christian civilization. From the 11th to 13th centuries, Latin Christendom rose to the central role of the Western world. The

has had a profound influence on Western civilization and on cultures around the globe; it has contributed to the formation of Western law, Western art, art, Western literature, texts, and education. With a literary tradition spanning two millennia, the Bible is one of the most influential works ever written.

According to ''100 Years of Nobel Prizes'' a review of the Nobel Prizes award between 1901 and 2000 reveals that (65.4%) of Nobel Prizes Laureates, List of Christian Nobel laureates, have identified Christianity in its various forms as their religious preference.Baruch A. Shalev, ''100 Years of Nobel Prizes'' (2003), Atlantic Publishers & Distributors, p. 57: between 1901 and 2000 reveals that 654 Laureates belong to 28 different religions. Most (65.4%) have identified Christianity in its various forms as their religious preference. Outside the Western world, Christianity has had an influence on various cultures, such as in Africa, the Near East, Middle East, East Asia, Southeast Asia, and the Indian subcontinent. List of Christian scientists and scholars of the medieval Islamic world, Eastern Christian scientists and scholars of the medieval Islamic world (particularly Syriac Orthodox Church, Jacobite and Nestorianism, Nestorian Christians) contributed to the Arab Islamic Golden Age, Islamic civilization during the reign of the Umayyad and the Abbasids, Abbasid, by translating works of Greek philosophers to Syriac and afterwards, to Arabic language, Arabic. They also excelled in philosophy, science, theology, and medicine. Scholars and intellectuals agree Christians in the Middle East have made significant contributions to Arab and Islamic civilization since the introduction of

, and they have had a significant impact contributing the culture of the Mashriq, Turkey, and Iran.

Influence on Western culture

Western culture, throughout most of its history, has been nearly equivalent to Christian culture, and a large portion of the population of the Western Hemisphere can be described as practicing or nominal Christians. The notion of "Europe" and the "Western World" has been intimately connected with the concept of "Christianity and

". Many historians even attribute Christianity for being the link that created a unified European identity. Though Western culture contained several polytheistic religions during its early years under the Ancient Greece, Greek and Roman Empire, Roman empires, as the centralized Roman power waned, the dominance of the Catholic Church was the only consistent force in Western Europe. Until the

, Christian culture guided the course of philosophy, literature, art, music and science. Christian disciplines of the respective arts have subsequently developed into Christian philosophy, Christian art, Christian music, Christian literature, and so on. Christianity has had a significant impact on education, as the church created the bases of the Western system of education, and was the sponsor of Medieval university, founding universities in the Western world, as the university is generally regarded as an institution that has its origin in the

Historically, Christianity has often been a patron of science and medicine; many List of Catholic cleric-scientists, Catholic clergy, List of Jesuit scientists, Jesuits in particular, have been active in the sciences throughout history and have made significant contributions to the Christianity and science, development of science. Some scholars state that Christianity contributed to the rise of the

. Protestantism also has had an important influence on science. According to the Merton Thesis, there was a positive correlation between the rise of English Puritanism and German Pietism on the one hand, and early experimental science on the other. The civilizing influence of Christianity includes social welfare, contribution to the medical and health care, founding hospitals, economics (as the Protestant work ethic), architecture,Sir Banister Fletcher, ''History of Architecture on the Comparative Method''. politics, literature, Hygiene in Christianity, personal hygiene (Ablution in Christianity, ablution), and family life.

''Postchristianity'' is the term for the decline of Christianity, particularly in Christianity in Europe, Europe, Religion in Canada, Canada, Christianity in Australia, Australia, and to a minor degree the Southern Cone, in the 20th and 21st centuries, considered in terms of postmodernism. It refers to the loss of Christianity's monopoly on values and world view in historically Christian societies.

Ecumenism

Christian groups and List of Christian denominations, denominations have long expressed ideals of being reconciled, and in the 20th century, Christian ecumenism advanced in two ways.McManners, ''Oxford Illustrated History of Christianity'', pp. 581–584. One way was greater cooperation between groups, such as the World Evangelical Alliance founded in 1846 in London or the Edinburgh Missionary Conference of Protestants in 1910, the Justice, Peace and Creation Commission of the

founded in 1948 by Protestant and Orthodox churches, and similar national councils like the National Council of Churches in Australia, which includes Catholics. The other way was an institutional union with United and uniting churches, united churches, a practice that can be traced back to unions between Lutherans and Calvinists in early 19th-century Germany. Congregationalist, Methodist, and Presbyterian churches united in 1925 to form the United Church of Canada, and in 1977 to form the Uniting Church in Australia. The Church of South India was formed in 1947 by the union of Anglican, Baptist, Methodist, Congregationalist, and Presbyterian churches. The Christian Flag is an ecumenical flag designed in the early 20th century to represent all of Christianity and

. The ecumenical, monasticism, monastic Taizé Community is notable for being composed of more than one hundred monk, brothers from Protestant and Catholic traditions. The community emphasizes the reconciliation of all denominations and its main church, located in Taizé, Saône-et-Loire, France, is named the "Church of Reconciliation". The community is internationally known, attracting over 100,000 young Christian pilgrimage, pilgrims annually. Steps towards reconciliation on a global level were taken in 1965 by the Catholic and Orthodox churches, mutually revoking the excommunications that marked their East-West Schism, Great Schism in 1054; the Anglican Catholic International Commission (ARCIC) working towards full communion between those churches since 1970; and some Lutheran World Federation, Lutheran and Catholic churches signing the Joint Declaration on the Doctrine of Justification in 1999 to address conflicts at the root of the Protestant Reformation. In 2006, the World Methodist Council, representing all Methodist denominations, adopted the declaration.

Criticism, persecution, and apologetics

Criticism

Criticism of Christianity and Christians goes back to the Apostolic Age, with the New Testament recording friction between the followers of Jesus and the Pharisees and scribes (e.g. and ). In the 2nd century, Christianity was criticized by the Jews on various grounds, e.g. that the prophecies of the Hebrew Bible could not have been fulfilled by Jesus, given that he did not have a successful life. Additionally, a sacrifice to remove sins in advance, for everyone or as a human being, did not fit to the Jewish sacrifice ritual; furthermore, God in Judaism is said to judge people on their deeds instead of their beliefs. One of the first comprehensive attacks on Christianity came from the Greek philosopher Celsus, who wrote ''The True Word'', a polemic criticizing Christians as being unprofitable members of society. In response, the church father

published his treatise ''Contra Celsum'', or ''Against Celsus'', a seminal work of Christian apologetics, which systematically addressed Celsus's criticisms and helped bring Christianity a level of academic respectability. By the 3rd century, criticism of Christianity had mounted. Wild rumors about Christians were widely circulated, claiming that they were atheism, atheists and that, as part of their rituals, they devoured human infants and engaged in incestuous orgies. The Neoplatonism, Neoplatonist philosopher Porphyry (philosopher), Porphyry wrote the fifteen-volume ''Adversus Christianos'' as a comprehensive attack on Christianity, in part building on the teachings of Plotinus. By the 12th century, the Mishneh Torah (i.e., Rabbi Moses Maimonides) was criticizing Christianity on the grounds of idol worship, in that Christians attributed divinity to Jesus, who had a physical body. In the 19th century, Nietzsche began to write a series of polemics on the "unnatural" teachings of Christianity (e.g. sexual abstinence), and continued his criticism of Christianity to the end of his life. In the 20th century, the philosopher Bertrand Russell expressed his criticism of Christianity in ''Why I Am Not a Christian'', formulating his rejection of Christianity in the setting of logical arguments. Criticism of Christianity continues to date, e.g. Jewish and Muslim theologians criticize the doctrine of the

held by most Christians, stating that this doctrine in effect assumes that there are three gods, running against the basic tenet of monotheism. New Testament scholar Robert M. Price has outlined the possibility that some Bible stories are based partly on myth in ''The Christ Myth Theory and its problems''.

Persecution

Christians are one of the most Persecution of Christians, persecuted religious group in the world, especially in the Christianity in the Middle East, Middle-East,

and South and East Asia. In 2017, Open Doors estimated approximately 260 million Christians are subjected annually to "high, very high, or extreme persecution"Weber, Jeremy. "'Worst year yet’: the top 50 countries where it's hardest to be a Christian".

Apologetics

Christian apologetics aims to present a reason, rational basis for Christianity. The word "apologetic" (Greek: ἀπολογητικός ''apologētikos'') comes from the Greek verb ἀπολογέομαι ''apologeomai'', meaning "(I) speak in defense of". Christian apologetics has taken many forms over the centuries, starting with Paul the Apostle. The philosopher

presented five arguments for God's existence in the ''Summa Theologica'', while his ''Summa contra Gentiles'' was a major apologetic work. Another famous apologist, G. K. Chesterton, wrote in the early twentieth century about the benefits of religion and, specifically, Christianity. Famous for his use of paradox, Chesterton explained that while Christianity had the most mysteries, it was the most practical religion. He pointed to the Role of the Christian Church in civilization, advance of Christian civilizations as proof of its practicality. The physicist and priest John Polkinghorne, in his ''Questions of Truth'', discusses the subject of religion and science, a topic that other Christian apologists such as Ravi Zacharias, John Lennox, and William Lane Craig have engaged, with the latter two men opining that the Religious interpretations of the Big Bang theory, inflationary Big Bang model is evidence for the existence of God. Creationist apologetics is apologetics that aims to defend creationism.
