'''Christianity''' is an [[Abrahamic]] [[monotheistic]] [[religion]], which states that [[Jesus in Christianity|Jesus]] is the [[Son of God (Christianity)|Son of God]] and [[Resurrection of Jesus|rose from the dead]] after [[Crucifixion of Jesus|his crucifixion]], whose coming as the [[Messiah#Christianity|messiah]] ([[Christ (title)|Christ]]) was [[Old Testament messianic prophecies quoted in the New Testament|prophesied]] in the [[Old Testament]] and chronicled in the [[New Testament]]. It is the [[Major religious groups|world's largest]] and most widespread religion with over 2.3&nbsp;billion followers, comprising around 28.8% of the [[world population]]. Its adherents, known as [[Christians]], are estimated to make up a majority of the population in [[Christianity by country|120 countries and territories]].

Christianity remains [[Christian culture|culturally diverse]] in its [[Western Christianity|Western]] and [[Eastern Christianity|Eastern branches]], and doctrinally diverse concerning [[Justification (theology)|justification and the nature of salvation]], [[ecclesiology]], [[ordination]], and [[Christology]]. Most [[List of Christian denominations|Christian denominations]], however, generally hold in common the belief that Jesus is [[God the Son]]{{refn|group=note|name="nontrinitarianism"}}—the [[Logos (Christianity)|Logos]] [[Incarnation (Christianity)|incarnated]]—who [[Ministry of Jesus|ministered]], [[Passion of Jesus|suffered]], and died on a cross, but rose from the dead for the [[Salvation in Christianity|salvation]] of humankind; this message is called [[the gospel]], meaning the "good news". The four [[Gospel|canonical gospels]] of [[Gospel of Matthew|Matthew]], [[Gospel of Mark|Mark]], [[Gospel of Luke|Luke]] and [[Gospel of John|John]] describe Jesus' life and teachings as preserved in the early Christian tradition, with the Old Testament as the gospels' respected background.

Christianity [[Christianity in the 1st century|began in the 1st century]], after the death of Jesus, as a [[Second Temple Judaism|Judaic]] sect with [[Hellenistic Judaism|Hellenistic influence]] in the [[Roman Empire|Roman]] province of [[Judaea (Roman province)|Judaea]]. The [[disciple (Christianity)|disciples]] of Jesus [[Spread of Christianity|spread their faith]] around the [[Eastern Mediterranean]] area, despite [[Persecution of Christians in the Roman Empire|significant persecution]]. The inclusion of [[Gentile]]s led Christianity to slowly [[Split of Christianity and Judaism|separate from Judaism]] in the 2nd century. Emperor [[Constantine I]] decriminalized Christianity in the [[Roman Empire]] by the [[Edict of Milan]] in 313 AD. Later, Constantine convened the [[First Council of Nicaea|Council of Nicaea]] in 325 AD, where the [[Nicene Creed]] was adopted, and where Early Christianity was consolidated into what would become the state religion of the Roman Empire by around 380 AD. The [[Church of the East]] and [[Oriental Orthodoxy]] both split over differences in [[Christology]] during the 5th century, while the [[Eastern Orthodox Church]] and the [[Catholic Church]] separated in the [[East–West Schism]] in the year 1054. [[Protestantism]] split into numerous denominations from the Catholic Church during the [[Reformation]] era (16th century). Following the [[Age of Discovery]] (15th–17th century), Christianity expanded throughout the world via [[Christian mission|missionary work]], [[evangelism]], immigration, and extensive trade. Christianity played [[Role of Christianity in civilization|a prominent role]] in the [[Christian ethics|development]] of [[Western civilization]], particularly in Europe from [[late antiquity]] and the [[Middle Ages]].

The three main [[Christian denomination|branches of Christianity]] are [[Catholic Church|Catholicism]] (1.3 billion people), [[Protestantism]] (800 million),{{refn|group=note|The denominations of [[Adventism]], [[Anabaptism]] ([[Amish]], [[Apostolic Christian Church|Apostolic]], [[Bruderhof Communities|Bruderhof]], [[Hutterites]], [[Mennonites]], [[River Brethren]], and [[Schwarzenau Brethren]]), [[Anglicanism]], [[Baptist]]s, [[Lutheranism]], [[Methodism]], [[Moravian Church|Moravianism/Hussites]], [[Pentecostalism]], [[Plymouth Brethren]], [[Quakers|Quakerism]], [[Calvinism|Reformed Christianity]] ([[Congregational church|Congregationalists]], [[Continental Reformed Protestantism|Continental Reformed]], and [[Presbyterianism|Presbyterians]]), and [[Waldensians|Waldensianism]] are the main families of Protestantism.

Early Jewish Christians referred to themselves as being of 'The Way' ({{langx|grc-x-koine|τῆς ὁδοῦ|tês hodoû}}), an expression possibly coming from [[Isaiah 40:3]], "prepare the way of the Lord".{{refn|group=note|It appears in the Acts of the Apostles, {{bibleverse|Acts|9:2|KJV}}, {{bibleverse|Acts|19:9|KJV}} and {{bibleverse|Acts|19:23|KJV}}.

Jewish Christianity soon attracted [[Gentile]] [[God-fearer]]s, posing a problem for its [[Jewish principles of faith|Jewish religious outlook]], which insisted on close observance of the Jewish commandments. [[Paul the Apostle]] solved this by insisting that salvation by [[Pistis Christou|faith in Christ]], and [[Participation in Christ|participation]] in his death and resurrection by their baptism, sufficed.<ref>{{Cite book |last=Seifrid |first=Mark A. |author-link=Mark A.

This formative period was followed by the early [[bishop]]s, whom Christians consider the [[apostolic succession|successors of Christ's apostles]]. From the year 150, Christian teachers began to produce theological and apologetic works aimed at defending the faith. These authors are known as the [[Church Fathers]], and the study of them is called [[patristics]]. Notable early Fathers include [[Ignatius of Antioch]], [[Polycarp]], [[Justin Martyr]], [[Irenaeus]], [[Tertullian]], [[Clement of Alexandria]] and [[Origen]].

[[Persecution of Christians]] occurred intermittently and on a small scale by both Jewish and [[Persecution of early Christians by the Romans|Roman authorities]], with Roman action starting at the time of the [[Great Fire of Rome]] in 64 AD. Examples of early executions under Jewish authority reported in the [[New Testament]] include the deaths of [[Saint Stephen]]<ref>{{bibleverse|Acts|7:59}}</ref> and [[James, son of Zebedee]].<ref>{{bibleverse|Acts|12:2}}</ref> The [[Decian persecution]] was the first empire-wide conflict,<ref>Martin, D. 2010.

The [[Diocletianic Persecution]] beginning in 303 AD was also particularly severe. Roman persecution ended in 313 AD with the [[Edict of Milan]].

While [[Proto-orthodox Christianity]] was becoming dominant, heterodox sects also existed at the same time, which held radically different beliefs. [[Gnostic Christianity]] developed a [[duotheistic]] doctrine based on illusion and enlightenment rather than forgiveness of sin. With only a few scriptures overlapping with the developing orthodox canon, most [[Gnostic texts]] and [[Gnostic gospels]] were eventually considered heretical and suppressed by mainstream Christians. A gradual splitting off of [[Gentile Christianity]] left [[Jewish Christians]] continuing to follow the [[Law of Moses]], including practices such as circumcision. By the fifth century, they and the [[Jewish–Christian gospels]] would be largely suppressed by the dominant sects in both Judaism and Christianity.

{{Main|Christianity in the Middle Ages}}

==== Early Middle Ages ====
With the decline and [[Fall of the Western Roman Empire|fall of the Roman Empire in the West]], the [[papacy]] became a political player, first visible in [[Pope Leo I|Pope Leo]]'s diplomatic dealings with [[Attila the Hun|Huns]] and [[Vandals]].<ref name="Gonzalez-p238" /> The church also entered into a long period of missionary activity and expansion among the various tribes. While [[Arianism|Arianists]] instituted the death penalty for practicing pagans (see the [[Massacre of Verden]], for example), [[Catholicism]] also spread among the [[Hungarians]], the [[Germanic peoples|Germanic]],<ref name="Gonzalez-p238">{{harvnb|González|1984|pp=238–242}}</ref> the [[Celts|Celtic]], the [[Baltic peoples|Baltic]] and some [[Slavic peoples]].<ref>{{harvnb|Chadwick|1995|pp=60, 130}}</ref>

Around 500, Christianity was thoroughly integrated into Byzantine and [[Ostrogothic Kingdom|Kingdom of Italy]] culture<ref>{{Cite book |last=Harari |first=Yuval Noah |title=Sapiens: A Brief History of Humankind |publisher=Penguin Random House |year=2015 |isbn=978-0-09-959008-8 |location=London |pages=243, 247 |translator-last=Harari |translator-first=Yuval Noah |author-link=Yuval Noah Harari |translator-last2=Purcell |translator-first2=John |translator-last3=Watzman |translator-first3=Haim |translator-link=Yuval Noah Harari |translator-link3=Haim Watzman}}</ref> and [[Benedict of Nursia]] set out [[Rule of Saint Benedict|his Monastic Rule]], establishing a system of regulations for the foundation and running of [[monasteries]].<ref name="Gonzalez-p238" /> [[Monasticism]] became a powerful force throughout Europe,<ref name="Gonzalez-p238" /> and gave rise to many early centers of learning, most famously in [[Ireland]], [[Scotland]], and [[Gaul]], contributing to the [[Carolingian Renaissance]] of the 9th century.

In the West, from the 11th century onward, some older cathedral schools [[Medieval university|became universities]] (see, for example, [[University of Oxford]], [[University of Paris]] and [[University of Bologna]]). Previously, higher education had been the domain of Christian [[cathedral school]]s or [[monastic school]]s (''Scholae monasticae''), led by [[monk]]s and [[nun]]s. Evidence of such schools dates back to the 6th century&nbsp;AD.<ref>Riché, Pierre (1978): "Education and Culture in the Barbarian West: From the Sixth through the Eighth Century", Columbia: University of South Carolina Press, {{ISBN|0872493768}}, pp.&nbsp;126–127, 282–298</ref> These new universities expanded the curriculum to include academic programs for clerics, lawyers, civil servants, and physicians.<ref>Rudy, ''The Universities of Europe, 1100–1914'', p. 40</ref> The university is generally regarded as an institution that has its origin in the [[History of Christianity|Medieval Christian]] setting.<ref name=verger1999>{{cite book |last=Verger |first=Jacques |year=1999 |author-link=:fr:Jacques Verger|title=Culture, enseignement et société en Occident aux XIIe et XIIIe siècles |edition=1st |language=fr |publisher=Presses universitaires de Rennes in Rennes |isbn=978-2868473448 |url=https://openlibrary.org/works/OL822497W |access-date=17 June 2014}}</ref><ref>Verger, Jacques.

Accompanying the rise of the "new towns" throughout Europe, [[mendicant order]]s were founded, bringing the [[Consecrated life (Catholic Church)|consecrated religious life]] out of the monastery and into the new urban setting. The two principal mendicant movements were the [[Franciscans]]<ref>{{harvnb|González|1984|pp=303–307, 310ff., 384–386}}</ref> and the [[Dominican Order|Dominicans]],<ref>{{harvnb|González|1984|pp=305, 310ff., 316ff}}</ref> founded by [[Francis of Assisi]] and [[Saint Dominic|Dominic]], respectively. Both orders made significant contributions to the development of the great universities of Europe. Another new order was the [[Cistercians]], whose large, isolated monasteries spearheaded the settlement of former wilderness areas. In this period, church building and ecclesiastical architecture reached new heights, culminating in the orders of [[Romanesque architecture|Romanesque]] and [[Gothic architecture]] and the building of the great European cathedrals.<ref>{{harvnb|González|1984|pp=321–323, 365ff}}</ref>

[[Christian nationalism]] emerged during this era in which Christians felt the desire to recover lands in which Christianity had historically flourished.<ref>{{cite book |title=Parole de l'Orient |volume=30 |year=2005 |publisher=Université Saint-Esprit |page=488}}</ref> From 1095 under the pontificate of [[Urban II]], the [[First Crusade]] was launched.<ref>{{harvnb|González|1984|pp=292–300}}</ref> These were a series of military campaigns in the [[Holy Land]] and elsewhere, initiated in response to pleas from the Byzantine Emperor [[Alexios I]] for aid against [[Turkish people|Turkish]] expansion. The Crusades ultimately failed to stifle Islamic aggression and even contributed to Christian enmity with the sacking of [[Constantinople]] during the [[Fourth Crusade]].<ref>Riley-Smith. ''The Oxford History of the Crusades''.</ref>

The Christian Church experienced internal conflict between the 7th and 13th centuries that resulted in a [[East-West Schism|schism]] between the [[Latin Church]] of [[Western Christianity]] branch, the now-Catholic Church, and an [[Eastern Christianity|Eastern]], largely Greek, branch (the [[Eastern Orthodox Church]]). The two sides disagreed on a number of administrative, liturgical and doctrinal issues, most prominently [[Eastern Orthodox opposition to papal supremacy]].<ref>{{cite web|url=https://www.orthodoxinfo.com/general/greatschism.aspx|title = The Great Schism: The Estrangement of Eastern and Western Christendom|publisher=Orthodox Information Centre|access-date = 26 May 2007|archive-date = 29 June 2007|archive-url = https://web.archive.org/web/20070629153450/http://www.orthodoxinfo.com/general/greatschism.aspx|url-status = dead}}</ref><ref>Duffy, ''Saints and Sinners'' (1997), p. 91</ref> The [[Second Council of Lyon]] (1274) and the [[Council of Florence]] (1439) attempted to reunite the churches, but in both cases, the Eastern Orthodox refused to implement the decisions, and the two principal churches remain in schism to the present day. However, the Catholic Church has achieved union with various [[Eastern Catholic Churches|smaller eastern churches]].

In the thirteenth century, a new emphasis on Jesus' suffering, exemplified by the Franciscans' preaching, had the consequence of turning worshippers' attention towards Jews, on whom [[Jewish deicide|Christians had placed the blame for Jesus' death]]. Christianity's limited tolerance of Jews was not new—Augustine of Hippo said that Jews should not be allowed to enjoy the citizenship that Christians took for granted—but the growing antipathy towards Jews was a factor that led to [[Edict of Expulsion|the expulsion of Jews from England in 1290]], the first of many such expulsions in Europe.<ref>{{cite book |last=MacCulloch |first=Diarmaid |title=Christianity: The First Three Thousand Years |publisher=Penguin |year=2011 |url=https://books.google.com/books?id=7x4m20TRYzQC |isbn=978-1-101-18999-3}}</ref><ref>{{cite book |last=Telushkin |first=Joseph |title=Jewish Literacy |publisher=HarperCollins |pages=[https://archive.org/details/jewishliteracy00telu/page/192 192–193] |year=2008 |isbn=978-0-688-08506-3 |url=https://archive.org/details/jewishliteracy00telu/page/192}}</ref>

Beginning around 1184, following the crusade against [[Cathars|Cathar]] heresy,<ref>{{harvnb|González|1984|pp=300, 304–305}}</ref> various institutions, broadly referred to as the [[Inquisition]], were established with the aim of suppressing [[heresy]] and securing religious and doctrinal unity within Christianity through [[religious conversion|conversion]] and prosecution.<ref>{{harvnb|González|1984|pp=310, 383, 385, 391}}</ref>

==== Protestant Reformation and Counter-Reformation ====
{{Main|Reformation|Counter-Reformation}}
{{See also|European wars of religion|Renaissance Papacy}}
[[File:Luther 95 Thesen.png|thumb|upright|[[Martin Luther]] initiated the [[Reformation]] with his ''[[Ninety-five Theses]]'' in 1517.]]

The 15th-century [[Renaissance]] brought about a renewed interest in ancient and classical learning. During the [[Reformation]], [[Martin Luther]] posted the ''[[Ninety-five Theses]]'' 1517 against the sale of [[indulgences]].<ref name="Simon">Simon. ''Great Ages of Man: The Reformation''. pp. 39, 55–61.</ref> Printed copies soon spread throughout Europe. In 1521 the [[Edict of Worms]] condemned and excommunicated Luther and his followers, resulting in the schism of the [[Western Christianity|Western Christendom]] into several branches.<ref>Simon. ''Great Ages of Man: The Reformation''. p. 7.</ref>

Other reformers like [[Huldrych Zwingli|Zwingli]], [[Johannes Oecolampadius|Oecolampadius]], [[John Calvin|Calvin]], [[John Knox|Knox]], and [[Jacobus Arminius|Arminius]] further criticized Catholic teaching and worship. These challenges developed into the movement called [[Protestantism]], which repudiated the [[papal primacy|primacy of the pope]], the role of tradition, the [[Catholic sacraments|seven sacraments]], and other doctrines and practices.<ref name="Simon" /> The [[English Reformation|Reformation in England]] began in 1534, when [[Henry VIII of England|King Henry VIII]] had himself [[Act of Supremacy|declared head]] of the [[Church of England]]. Beginning in 1536, the monasteries throughout England, Wales and Ireland were [[Dissolution of the monasteries|dissolved]].<ref>Schama. ''A History of Britain''. pp. 306–310.</ref>

[[Thomas Müntzer]], [[Andreas Karlstadt]] and other theologians perceived both the Catholic Church and the confessions of the [[Magisterial Reformation]] as corrupted. Their activity brought about the [[Radical Reformation]], which gave birth to various [[Anabaptism|Anabaptist]] denominations.

[[File:Michelangelo's Pieta 5450 cropncleaned edit.jpg|thumb|[[Michelangelo]]'s 1498–99 ''[[Michelangelo's Pietà|Pietà]]'' in [[St. Peter's Basilica]]; the Catholic Church was among the patronages of the [[Renaissance]].<ref>National Geographic, 254.</ref><ref>Jensen, De Lamar (1992), ''Renaissance Europe'', {{ISBN|0395889472}}</ref><ref>{{Cite book|last=Levey|first=Michael|title=Early Renaissance|publisher=Penguin |year=1967}}</ref>]]
Partly in response to the Protestant Reformation, the Catholic Church engaged in a substantial process of reform and renewal, known as the [[Counter-Reformation]] or Catholic Reform.{{sfn|Bokenkotter|2004|pp=242–244}} The [[Council of Trent]] clarified and reasserted Catholic doctrine. During the following centuries, competition between Catholicism and Protestantism became deeply entangled with political struggles among European states.<ref>Simon. ''Great Ages of Man: The Reformation''. pp. 109–120.</ref>

Meanwhile, the discovery of America by [[Christopher Columbus]] in 1492 brought about a new wave of missionary activity. Partly from missionary zeal, but under the impetus of [[Colonialism|colonial expansion]] by the European powers, Christianity spread to the Americas, Oceania, East Asia and sub-Saharan Africa.

Throughout Europe, the division caused by the Reformation led to outbreaks of [[religious violence]] and the establishment of separate state churches in Europe. [[Lutheranism]] spread into the northern, central, and eastern parts of present-day Germany, [[Livonia]], and Scandinavia. [[Anglicanism]] was established in England in 1534. [[Calvinism]] and its varieties, such as [[Presbyterianism]], were introduced in Scotland, the Netherlands, Hungary, Switzerland, and France. [[Arminianism]] gained followers in the Netherlands and [[Frisia]]. Ultimately, these differences led to the outbreak of [[religious war|conflicts]] in which religion played a key factor. The [[Thirty Years' War]], the [[English Civil War]], and the [[French Wars of Religion]] are prominent examples. These events intensified the [[Christian debate on persecution and toleration]].<ref>A general overview about the English discussion is given in Coffey, ''Persecution and Toleration in Protestant England 1558–1689''.</ref>

In the revival of neoplatonism [[Renaissance humanism|Renaissance humanists]] did not reject Christianity; quite the contrary, many of the greatest works of the [[Renaissance]] were devoted to it, and the Catholic Church patronized many works of [[Renaissance art]].<ref name="openuni">Open University, ''[https://www.open.ac.uk/Arts/renaissance2/religion.htm Looking at the Renaissance: Religious Context in the Renaissance]'' (Retrieved 10 May 2007)</ref> Much, if not most, of the new art was commissioned by or in dedication to the Church.<ref name="openuni" /> Some scholars and historians attribute Christianity to having contributed to the rise of the [[Scientific Revolution]].<ref>Some scholars and historians attribute Christianity to having contributed to the rise of the Scientific Revolution:

In the era known as the [[Great Divergence]], when in the West, the [[Age of Enlightenment]] and the [[Scientific Revolution]] brought about great societal changes, Christianity was confronted with various forms of [[skepticism]] and with certain modern [[Ideology|political ideologies]], such as versions of [[socialism]] and [[liberalism]].<ref>{{cite book|last=Novak|first=Michael|title=Catholic social thought and liberal institutions: Freedom with justice|year=1988|publisher=Transaction|isbn=978-0-88738-763-0|page=63|url=https://books.google.com/books?id=7pb1GDmxA1UC&pg=PA63}}</ref> Events ranged from mere [[anti-clericalism]] to violent outbursts against Christianity, such as the [[dechristianisation of France during the French Revolution|dechristianization of France during the French Revolution]],<ref>Mortimer Chambers, ''The Western Experience'' (vol. 2) chapter 21.</ref> the [[Spanish Civil War]], and certain [[Marxism|Marxist]] movements, especially [[Russian Revolution (1917)|the Russian Revolution]] and the [[persecution of Christians in the Soviet Union]] under [[state atheism]].<ref>''Religion and the State in Russia and China: Suppression, Survival, and Revival'', by Christopher Marsh, p. 47.

Especially pressing in Europe was the formation of [[nation states]] after the [[Napoleonic era]]. In all European countries, different Christian denominations found themselves in competition to greater or lesser extents with each other and with the state. Variables were the relative sizes of the denominations and the religious, political, and ideological orientation of the states. Urs Altermatt of the [[University of Fribourg]], looking specifically at Catholicism in Europe, identifies four models for the European nations. In traditionally Catholic-majority countries such as Belgium, Spain, and Austria, to some extent, religious and national communities are more or less identical.

Competition is found in Germany, the Netherlands, and again Switzerland, all countries with minority Catholic populations, which to a greater or lesser extent identified with the nation. Finally, separation between religion (again, specifically Catholicism) and the state is found to a great degree in France and Italy, countries where the state actively opposed itself to the authority of the Catholic Church.<ref>{{cite book|last=Altermatt|first=Urs|title=Religion und Nation: Katholizismen im Europa des 19. und 20.

Concise doctrinal statements or confessions of religious beliefs are known as [[creeds]]. They began as baptismal formulae and were later expanded during the [[Christology|Christological]] controversies of the 4th and 5th centuries to become statements of faith. "[[Jesus is Lord]]" is the earliest creed of Christianity and continues to be used, as with the [[World Council of Churches]].<ref>{{Cite book |last=Tayviah |first=Frederick K. D. |title=Why Do Bad Things Keep on Happening? |year=1995 |publisher=CSS Publishing |isbn=978-1-55673-979-8 |page=29}}</ref>

The [[Apostles' Creed]] is the most widely accepted statement of the articles of Christian faith. It is used by a number of [[List of Christian denominations|Christian denominations]] for both [[liturgy|liturgical]] and [[catechesis|catechetical]] purposes, most visibly by liturgical churches of [[Western Christian]] tradition, including the [[Latin Church]] of the [[Catholic Church]], [[Lutheranism]], [[Anglicanism]], and [[Western Rite Orthodoxy]]. It is also used by [[Presbyterianism|Presbyterians]], [[Methodism|Methodists]], and [[Congregational church|Congregationalists]].

This particular creed was developed between the 2nd and 9th centuries. Its central doctrines are those of the [[Trinity]] and [[God in Christianity|God]] the [[Creator deity|Creator]]. Each of the doctrines found in this creed can be traced to statements current in the [[Apostolic Age|apostolic period]]. The creed was apparently used as a summary of Christian doctrine for baptismal candidates in the churches of Rome.<ref>Pelikan/Hotchkiss, ''Creeds and Confessions of Faith in the Christian Tradition''.</ref> Its points include:

=== Jesus ===
{{Main|Jesus in Christianity|Christ (title)}}
{{See also|Incarnation (Christianity)|Jesus in comparative mythology}}
[[File:CompositeJesus.JPG|thumb|Various [[Depiction of Jesus|depictions of Jesus]]]]

The central tenet of Christianity is the belief in [[Jesus]] as the [[Son of God (Christianity)|Son of God]]{{refn|group=note|name="nontrinitarianism"}} and the [[Messiah]] (Christ).<ref>{{harvnb|Woodhead|2004|p=45}}</ref><ref>{{harvnb|Woodhead|2004|p=n.p.}}</ref> Christians believe that Jesus, as the Messiah, was [[anointing|anointed]] by God as savior of humanity and hold that Jesus' coming was the fulfillment of [[Christian messianic prophecies|messianic prophecies]] of the [[Old Testament]]. The Christian concept of messiah differs significantly from [[Messiah in Judaism|the contemporary Jewish concept]]. The core Christian belief is that through belief in and acceptance of [[Death and Resurrection of Jesus|the death and resurrection of Jesus]], [[original sin|sinful]] humans can be reconciled to God, and thereby are offered salvation and the promise of [[Immortality|eternal life]].<ref>Metzger/Coogan, ''Oxford Companion to the Bible'', pp. 513, 649.</ref>

While there have been many [[Christian theology|theological]] disputes over the [[Christology|nature of Jesus]] over the earliest centuries of Christian history, generally, Christians believe that Jesus is [[Incarnation (Christianity)|God incarnate]] and "[[Hypostatic union|true God and true man]]" (or both fully divine and fully human). Jesus, having become [[Incarnation (Christianity)|fully human]], suffered the pains and temptations of a mortal man, but did not [[Christian views on sin|sin]]. As fully God, he rose to life again. According to the [[New Testament]], he [[Resurrection of Jesus|rose]] from the dead,<ref>{{Bibleverse|Acts|2:24}}, {{Bibleref2-nb|Acts|2:31–32}}, {{Bibleref2-nb|Acts|3:15}}, {{Bibleref2-nb|Acts|3:26}}, {{Bibleref2-nb|Acts|4:10}}, {{Bibleref2-nb|Acts|5:30}}, {{Bibleref2-nb|Acts|10:40–41}}, {{Bibleref2-nb|Acts|13:30}}, {{Bibleref2-nb|Acts|13:34}}, {{Bibleref2-nb|Acts|13:37}}, {{Bibleref2-nb|Acts|17:30–31}}, {{Bibleverse|Romans|10:9}}, {{bibleverse|1Cor|15:15 || 1 Cor. 15:15}}, {{bibleref2-nb|1Cor|6:14}}, {{bibleverse|2Cor|4:14 || 2 Cor. 4:14}}, {{Bibleverse|Gal|1:1}}, {{Bibleverse|Eph|1:20}}, {{Bibleverse|Col|2:12}}, {{bibleverse|1Thess|1:10 || 1 Thess. 11:10}}, {{Bibleverse|Heb.|13:20}}, {{bibleverse|1Pet|1:3 || 1 Pet. 1:3}}, {{bibleref2-nb|1Pet|1:21}}</ref> [[Ascension of Jesus|ascended]] to heaven, is seated at the right hand of the Father,<ref>[[s:Nicene Creed]]</ref> and will ultimately [[Second Coming|return]]<ref>{{bibleverse|Acts|1:9–11}}</ref> to fulfill the rest of the [[Messianic prophecy]], including the [[resurrection of the dead]], the [[Last Judgment]], and the final establishment of the [[Kingdom of God (Christianity)|Kingdom of God]].

According to the [[canonical gospels]] of [[Gospel of Matthew|Matthew]] and [[Gospel of Luke|Luke]], Jesus was [[Incarnation (Christianity)|conceived]] by the [[Holy Spirit (Christianity)|Holy Spirit]] and [[Nativity of Jesus|born]] from [[Mary, mother of Jesus|the Virgin Mary]]. Little of Jesus' childhood is recorded in the canonical gospels, although [[infancy gospels]] were popular in antiquity.<ref>{{Cite book |last=Gambero |first=Luigi |url=https://books.google.com/books?id=dsZzsAtggnUC&q=L.+Gambero%2C+Mary+and+the+Fathers+of+the+Church |title=Mary and the Fathers of the Church: The Blessed Virgin Mary in Patristic Thought |publisher=Ignatius |year=1999 |isbn=978-0-89870-686-4 |via=Google Books}}</ref> In comparison, his adulthood, especially the week before his death, is well documented in the gospels contained within the [[New Testament]], because that part of his life is believed to be most important.

Christians consider the resurrection of Jesus to be the cornerstone of their faith (see [[1 Corinthians 15]]).<ref>{{Cite book |last=Hanegraaff |first=Hank |url=https://books.google.com/books?id=bZfZYMt8Tx4C |title=Resurrection: The Capstone in the Arch of Christianity |year=2002 |publisher=Thomas Nelson |isbn=978-1-4185-1723-6}}</ref> Among Christian beliefs, the death and resurrection of Jesus are two core events on which much of Christian doctrine and theology is based.<ref>{{Cite web |title=The Significance of the Death and Resurrection of Jesus for the Christian |url=https://dlibrary.acu.edu.au/research/theology/Walsh.htm |url-status=dead |archive-url=https://web.archive.org/web/20070901153606/https://dlibrary.acu.edu.au/research/theology/Walsh.htm |archive-date=1 September 2007 |access-date=16 May 2007 |publisher=Australian Catholic University National}}</ref> According to the New Testament, Jesus was [[Crucifixion|crucified]], died a physical death, was buried within a tomb, and rose from the dead three days later.<ref>{{bibleverse|Jn.|19:30–31}} {{bibleverse|Mk.|16:1}} {{bibleref2-nb|Mark|16:6}}</ref>

The [[Overview of resurrection appearances in the Gospels and Paul|New Testament mentions]] several [[Resurrection of Jesus#Biblical accounts|post-resurrection appearances of Jesus]] on different occasions to his [[twelve apostles]] and [[disciple (Christianity)|disciples]], including "more than five hundred brethren at once",<ref>{{bibleverse|1Cor|15:6}}</ref> before Jesus' [[Ascension of Jesus|ascension]] to heaven. Jesus' death and resurrection are commemorated by Christians in all worship services, with special emphasis during [[Holy Week]], which includes [[Good Friday]] and [[Easter]] Sunday.

The death and resurrection of Jesus are usually considered the most important events in [[Christian theology]], partly because they demonstrate that Jesus has power over life and death and therefore has the authority and power to give people [[Eternal life (Christianity)|eternal life]].<ref>{{bibleverse || John|3:16}}, {{bibleref2-nb|John|5:24}}, {{bibleref2-nb|John|6:39–40}}, {{bibleref2-nb|John|6:47}}, {{bibleref2-nb|John|10:10}}, {{bibleref2-nb|John|11:25–26}}, and {{bibleref2-nb|John|17:3}}</ref>

Christian churches accept and teach the [[New Testament]] account of the resurrection of Jesus with very few exceptions.<ref>This is drawn from a number of sources, especially the early Creeds, the ''Catechism of the Catholic Church'', certain theological works, and various Confessions drafted during the Reformation including the ''Thirty Nine Articles of the Church of England'', works contained in the ''Book of Concord''.</ref> Some modern scholars use the belief of Jesus' followers in the resurrection as a point of departure for establishing the continuity of the [[historical Jesus]] and the proclamation of the [[early church]].<ref>Fuller, ''The Foundations of New Testament Christology'', p. 11.</ref> Some [[Liberal Christianity|liberal Christians]] do not accept a literal bodily resurrection,<ref>A [[Jesus Seminar]] conclusion held that "in the view of the Seminar, he did not rise bodily from the dead; the resurrection is based instead on [[vision hypothesis|visionary experiences]] of [[Saint Peter|Peter]], [[Paul the Apostle|Paul]], and [[Mary Magdalene|Mary]]."</ref><ref>Funk.

Modern Christian churches tend to be much more concerned with how humanity can be [[eternal salvation|saved]] from a universal condition of sin and death than the question of how both Jews and Gentiles can be in God's family. According to [[Eastern Orthodox]] theology, based upon their understanding of the atonement as put forward by Irenaeus' [[Recapitulation (Irenaeus)|recapitulation theory]], Jesus' death is a [[Ransom theory of atonement|ransom]]. This restores the relation with God, who is loving and reaches out to humanity, and offers the possibility of ''[[Theosis (Eastern Orthodox theology)|theosis]]'' c.q. [[Divinization (Christian)|divinization]], becoming the kind of humans God wants humanity to be. According to Catholic doctrine, Jesus' death [[Satisfaction theory of atonement|satisfies]] the wrath of God, aroused by the offense to God's honor caused by human's sinfulness. The Catholic Church teaches that salvation does not occur without faithfulness on the part of Christians; converts must live in accordance with principles of love and ordinarily must be baptized.<ref>{{Cite CCC|2.1|846}}</ref> In Protestant theology, Jesus' death is regarded as a [[Penal substitution|substitutionary penalty]] carried by Jesus, for the debt that has to be paid by humankind when it broke God's moral law.<ref>[[L.

Christians differ in their views on the extent to which individuals' salvation is pre-ordained by God.

According to this doctrine, God is not divided in the sense that each person has a third of the whole; rather, each person is considered to be fully God (see [[Perichoresis]]). The distinction lies in their relations, the Father being unbegotten; the Son being begotten of the Father; and the Holy Spirit proceeding from the Father and (in [[Western Christian]] theology) [[Filioque|from the Son]]. Regardless of this apparent difference, the three "persons" are each [[eternity|eternal]] and [[omnipotent]]. Other Christian religions including [[Unitarian Universalism]], [[Jehovah's Witnesses]], and [[Mormonism]], do not share those views on the Trinity.

==== Trinitarianism ====
{{Main|Trinitarianism}}
''Trinitarianism'' denotes Christians who believe in the concept of the [[Trinity]]. Almost all Christian denominations and churches hold Trinitarian beliefs. Although the words "Trinity" and "Triune" do not appear in the Bible, beginning in the 3rd century theologians developed the term and concept to facilitate [[apprehension (understanding)|apprehension]] of the New Testament teachings of God as being Father, Son, and Holy Spirit. Since that time, Christian theologians have been careful to emphasize that Trinity does not imply that there are three gods (the antitrinitarian heresy of [[Tritheism]]), nor that each hypostasis of the Trinity is one-third of an infinite God (partialism), nor that the Son and the Holy Spirit are beings created by and subordinate to the Father ([[Arianism]]). Rather, the Trinity is defined as one God in three persons.<ref>[[Jürgen Moltmann|Moltmann, Jürgen]]. ''The Trinity and the Kingdom: The Doctrine of God.'' Tr. from German. Fortress Press, 1993. {{ISBN|080062825X}}</ref>

==== Nontrinitarianism ====
{{Main|Nontrinitarianism}}
''Nontrinitarianism'' (or ''antitrinitarianism'') refers to theology that rejects the doctrine of the Trinity. Various nontrinitarian views, such as [[adoptionism]] or [[modalism]], existed in early Christianity, leading to disputes about [[Christology]].<ref>Harnack, ''[https://www.ccel.org/ccel/harnack/dogma1.ii.iii.iii.html History of Dogma]''.</ref> Nontrinitarianism reappeared in the [[Gnosticism]] of the [[Cathars]] between the 11th and 13th centuries, among groups with [[Unitarianism|Unitarian]] theology in the [[Protestant Reformation]] of the 16th century,<ref>''Pocket Dictionary of Church History'' Nathan P. Feldmeth p. 135 "Unitarianism. Unitarians emerged from Protestant Christian beginnings in the sixteenth century with a central focus on the unity of God and subsequent denial of the doctrine of the Trinity"</ref> in the 18th-century [[Age of Enlightenment|Enlightenment]], among [[Restorationism|Restorationist]] groups arising during the [[Second Great Awakening]] of the 19th century, and most recently, in [[Oneness Pentecostalism|Oneness Pentecostal]] churches.

=== Eschatology ===
{{Main|Christian eschatology}}
The end of things, whether the end of an individual life, the end of the age, or the end of the world, broadly speaking, is Christian eschatology; the study of the destiny of humans as it is revealed in the Bible. The major issues in Christian eschatology are the [[Great Tribulation|Tribulation]], death and the afterlife, (mainly for [[Evangelical Christianity|Evangelical]] groups) [[Millennialism|the Millennium]] and the following [[Rapture]], the [[Second Coming]] of Jesus, [[Resurrection of the Dead]], Heaven, (for [[Christian liturgy|liturgical]] branches) [[Purgatory]], and Hell, the [[Last Judgment]], the end of the world, and the [[New Heavens and New Earth]].

Christians believe that the second coming of Christ will occur at the [[eschatology|end of time]], after a period of severe persecution (the Great Tribulation). All who have died will be [[Resurrection of the dead|resurrected bodily from the dead]] for the Last Judgment. Jesus will fully establish the [[Kingdom of God]] in fulfillment of [[Bible prophecy|scriptural prophecies]].<ref>[[Thomas Aquinas]], [https://www.newadvent.org/summa/5.htm ''Summa Theologicum, Supplementum Tertiae Partis''] questions 69 through 99</ref><ref>{{cite web | last =Calvin | first =John | title =Institutes of the Christian Religion, Book Three, Ch. 25 | publisher =reformed.org | url =https://www.reformed.org/books/institutes/books/book3/bk3ch25.html | access-date =1 January 2008 | archive-date =10 December 2007 | archive-url =https://web.archive.org/web/20071210215923/http://www.reformed.org/books/institutes/books/book3/bk3ch25.html | url-status =dead }}</ref>

==== Death and afterlife ====
Most Christians believe that human beings experience divine judgment and are rewarded either with eternal life or [[hell|eternal damnation]]. This includes the [[Last Judgment|general judgement]] at the [[resurrection of the dead]] as well as the belief (held by Catholics,<ref>''[[Catholic Encyclopedia]]'', "[https://www.newadvent.org/cathen/08550a.htm Particular Judgment]".</ref><ref>Ott, ''Grundriß der Dogmatik'', p. 566.</ref> Orthodox<ref>David Moser, ''[https://www.orthodox.net/articles/about-prayer-for-the-dead.html What the Orthodox believe concerning prayer for the dead]''.</ref><ref>Ken Collins, ''[https://www.kencollins.com/question-45.htm What Happens to Me When I Die?] {{Webarchive|url=https://web.archive.org/web/20080928055816/https://www.kencollins.com/question-45.htm |date=28 September 2008 }}''.</ref> and most Protestants) in a [[particular judgment|judgment particular to the individual soul]] after physical death.

In the Catholic branch of Christianity, those who die in a state of grace, i.e., without any mortal sin separating them from God, but are still imperfectly purified from the effects of sin, undergo purification through the intermediate state of [[purgatory]] to achieve the holiness necessary for entrance into God's presence.<ref>{{cite web|url=https://www.vatican.va/holy_father/john_paul_ii/audiences/1999/documents/hf_jp-ii_aud_04081999_en.html |title=Audience of 4 August 1999 |publisher=Vatican.va |date=4 August 1999 |access-date=19 November 2010}}</ref> Those who have attained this goal are called ''saints'' (Latin ''sanctus'', "holy").<ref>''[[Catholic Encyclopedia]]'', "[https://www.newadvent.org/cathen/04171a.htm The Communion of Saints]".</ref>

Some Christian groups, such as Seventh-day Adventists, hold to [[Christian mortalism|mortalism]], the belief that the human soul is not naturally immortal, and is unconscious during the intermediate state between bodily death and resurrection. These Christians also hold to [[Annihilationism]], the belief that subsequent to the final judgement, the wicked will cease to exist rather than suffer everlasting torment. Jehovah's Witnesses hold to a similar view.<ref>"The death that Adam brought into the world is spiritual as well as physical, and only those who gain entrance into the Kingdom of God will exist eternally. However, this division will not occur until Armageddon, when all people will be resurrected and given a chance to gain eternal life. In the meantime, "the dead are conscious of nothing."

[[Rite (Christianity)|Christian rites]], rituals, and ceremonies are not celebrated in one single sacred language. Many ritualistic Christian churches make a distinction between sacred language, liturgical language and vernacular language. The three important languages in the [[Early Christianity|early Christian era]] were: [[Latin language|Latin]], [[Greek language|Greek]] and [[Syriac language|Syriac]].<ref>{{cite book |title=Paradise and Paradigm: Key Symbols in Persian Christianity and the Baha'i Faith |first=Christopher |last=Buck |year=1999 |isbn=978-0-7914-4062-9 |page=6 |publisher=State University of New York Press}}</ref><ref>{{cite book |title=Saving Paradise: How Christianity Traded Love of this World for Crucifixion and Empire |first=Rita |last=Nakashima Brock |year=2008 | isbn=978-0-8070-6750-5 |page=446 |publisher=Beacon |quote= the ancient church had three important languages: Greek, Latin, and Syriac.}}</ref><ref>{{cite book|title=The Rowman & Littlefield Handbook of Christianity in the Middle East |first=Mark |last=A.

=== Communal worship ===
[[Church service|Services]] of worship typically follow a pattern or form known as [[Christian liturgy|liturgy]].{{refn|group=note|Frequently a distinction is made between "liturgical" and "non-liturgical" churches based on how elaborate or antiquated the worship; in this usage, churches whose services are unscripted or improvised are described as "non-liturgical".<ref>{{cite book |last1=Russell |first1=Thomas Arthur |title=Comparative Christianity: A Student's Guide to a Religion and Its Diverse Traditions |year=2010 |publisher=Universal-Publishers |isbn=978-1-59942-877-2 |page=21 |url=https://books.google.com/books?id=FmMarHDbglgC&pg=PT21}}</ref>}} [[Justin Martyr]] described 2nd-century Christian liturgy in his ''[[First Apology]]'' ({{circa|150|lk=no}}) to Emperor [[Antoninus Pius]], and his description remains relevant to the basic structure of Christian liturgical worship:
{{blockquote|And Sundays, all who live in cities or in the country gather together to one place, and the memoirs of the apostles or the writings of the prophets are read, as long as time permits; then, when the reader has ceased, the [[Presbyter|president]] verbally instructs, and exhorts to the imitation of these good things. Then we all rise together and pray, and, as we before said, when our prayer is ended, bread and wine and water are brought, and the president in like manner offers prayers and thanksgivings, according to his ability, and the people assent, saying [[Amen]]; and there is a distribution to each, and a participation of that over which thanks have been given, and to those who are absent a portion is sent by the deacons. And they who are well to do, and willing, give what each thinks fit; and what is collected is deposited with the president, who succours the orphans and widows and those who, through sickness or any other cause, are in want, and those who are in bonds and the strangers sojourning among us, and in a word takes care of all who are in need.<ref name="justin">Justin Martyr, [https://www.earlychristianwritings.com/text/justinmartyr-firstapology.html ''First Apology''] §LXVII</ref>}}

Thus, as Justin described, Christians assemble for communal worship typically on Sunday, the [[Lord's Day]], though other liturgical practices often occur outside this setting. Scripture readings are drawn from the Old and New Testaments, but especially the gospels.{{refn|group=note|Often these are arranged on an [[annual cycle]], using a book called a [[lectionary]].}}<ref>{{harvnb|White|2010|p=36}}</ref> Instruction is given based on these readings, in the form of a [[sermon]] or [[homily]].

In Christian belief and practice, a ''sacrament'' is a [[Ritual|rite]], instituted by Christ, that confers [[divine grace|grace]], constituting a [[Sacred Mysteries|sacred mystery]]. The term is derived from the [[Latin]] word ''sacramentum'', which was used to translate the Greek word for ''mystery''. Views concerning both which rites are sacramental, and what it means for an act to be a sacrament, vary among Christian denominations and traditions.<ref name="ODCC1435">Cross/Livingstone. ''The Oxford Dictionary of the Christian Church''. pp. 1435ff.</ref>

The most conventional functional definition of a sacrament is that it is an outward sign, instituted by Christ, that conveys an inward, spiritual grace through Christ. The two most widely accepted sacraments are [[Baptism]] and the Eucharist; however, the majority of Christians also recognize five additional sacraments: [[Confirmation (Christian sacrament)|Confirmation]] ([[Chrismation]] in the Eastern tradition), [[Holy Orders]] (or [[ordination]]), [[Penance]] (or [[Confession (religion)|Confession]]), [[Anointing of the Sick]], and [[Matrimony]] (see [[Christian views on marriage]]).<ref name="ODCC1435" />

Taken together, these are the [[Sacraments of the Catholic Church|Seven Sacraments]] as recognized by churches in the [[High Church]] tradition—notably [[Sacraments of the Catholic Church|Catholic]], [[Eastern Orthodox]], [[Oriental Orthodox]], [[Independent Catholic Churches|Independent Catholic]], [[Old Catholic]], some [[Lutheranism|Lutherans]] and [[Anglican sacraments|Anglicans]]. Most other denominations and traditions typically affirm only Baptism and Eucharist as sacraments, while some Protestant groups, such as the Quakers, reject sacramental theology.<ref name="ODCC1435" /> Certain denominations of Christianity, such as Anabaptists, use the term "[[ordinance (Christianity)|ordinances]]" to refer to rites instituted by Jesus for Christians to observe.<ref>{{cite book |last1=Krahn |first1=Cornelius |last2=Rempel |first2=John D. |title=Ordinances |year=1989 |publisher=Global Anabaptist Mennonite Encyclopedia |url=https://gameo.org/index.php?title=Ordinances |quote=The term "ordinance" emphasizes the aspect of institution by Christ and the symbolic meaning.}}</ref> Seven ordinances have been taught in many [[Conservative Mennonite]] Anabaptist churches, which include "baptism, communion, footwashing, marriage, anointing with oil, the holy kiss, and the prayer covering".<ref name="Hartzler2013" /> 
 
In addition to this, the [[Church of the East]] has two additional sacraments in place of the traditional sacraments of Matrimony and the Anointing of the Sick. These include [[Holy Leaven]] (Melka) and the [[sign of the cross]].<ref>''Holy Apostolic Catholic Assyrian Church of the East, Archdiocese of Australia, New Zealand and Lebanon.''</ref> The [[Schwarzenau Brethren]] Anabaptist churches, such as the [[Dunkard Brethren Church]], observe the [[agape feast]] (lovefeast), a [[Rite (Christianity)|rite]] also observed by [[Moravian Church]] and [[Methodist Church]]es.<ref>{{cite news |title=Love Feast of the Dunkards; Peculiar Ceremonies of a Peculiar Sect of Christians |url=https://www.nytimes.com/1891/04/26/archives/love-feast-of-the-dunkards-peculiar-ceremonies-of-a-peculiar-sect.html |work=[[The New York Times]] |access-date=25 December 2023 |date=26 April 1891}}</ref>

Western Christian liturgical calendars are based on the cycle of the [[Roman Rite]] of the Catholic Church,<ref name="calendar" /> and Eastern Christians use analogous calendars based on the cycle of their respective [[Christian rite|rites]]. Calendars set aside holy days, such as [[Solemnity|solemnities]] which commemorate an event in the life of Jesus, Mary, or the [[saint]]s, and periods of [[fasting]], such as [[Lent]] and other pious events such as [[memoria]], or lesser festivals commemorating saints. Christian groups that do not follow a liturgical tradition often retain certain celebrations, such as [[Christmas]], [[Easter]], and [[Pentecost]]: these are the celebrations of Christ's birth, resurrection, and the descent of the Holy Spirit upon the Church, respectively. A few denominations such as [[Quakers|Quaker Christians]] make no use of a liturgical calendar.<ref>Hickman. ''Handbook of the Christian Year''.</ref>

Baptism is the ritual act, with the use of water, by which a person is admitted to membership of the [[Christian Church|Church]]. Beliefs on baptism vary among denominations. Differences occur firstly on whether the act has any spiritual significance. Some, such as the Catholic and [[Eastern Orthodox churches]], as well as Lutherans and Anglicans, hold to the doctrine of [[baptismal regeneration]], which affirms that baptism creates or strengthens a person's faith, and is intimately linked to salvation. [[Baptists]] and [[Plymouth Brethren]] view baptism as a purely symbolic act, an external public declaration of the inward change which has taken place in the person, but not as spiritually efficacious. Secondly, there are differences of opinion on the methodology (or mode) of the act. These modes are: by [[Immersion baptism|''immersion'']]; if immersion is total, by ''submersion''; by [[affusion]] (pouring); and by [[aspersion]] (sprinkling). Those who hold the first view may also adhere to the tradition of [[infant baptism]];<ref>{{Cite CCC|2.1|1213|quote=Through Baptism we are freed from sin and reborn as sons of God; we become members of Christ, are incorporated into the Church and made sharers in her mission.}}</ref><ref>"Holy Baptism is the sacrament by which God adopts us as his children and makes us members of Christ's Body, the Church, and inheritors of the kingdom of God" ([https://anglicansonline.org/basics/catechism.html#Holy%20Baptism Book of Common Prayer, 1979, Episcopal)] {{Webarchive|url=https://web.archive.org/web/20220219062846/http://anglicansonline.org/basics/catechism.html#Holy%20Baptism |date=19 February 2022 }}</ref><ref>"Baptism is the sacrament of initiation and incorporation into the body of Christ" ([https://www.backriverumc.com/userFiles/1257/by_water_and_the_spirit.pdf By Water and The Spirit – The Official United Methodist Understanding of Baptism (PDF)] {{webarchive |url=https://web.archive.org/web/20160313053601/https://www.backriverumc.com/userFiles/1257/by_water_and_the_spirit.pdf |date=13 March 2016 }}</ref><ref>"As an initiatory rite into membership of the Family of God, baptismal candidates are symbolically purified or washed as their sins have been forgiven and washed away" ([[William H.

As a result seven 'hours of prayer' emerged, which later became the monastic 'hours' and are still treated as 'standard' prayer times in many churches today.

[[File:Gutenberg Bible, Lenox Copy, New York Public Library, 2009. Pic 01.jpg|thumb|right|The [[Bible]] is the sacred book in Christianity.]]
Christianity, like other religions, has adherents whose beliefs and biblical interpretations vary. Christianity regards the [[biblical canon]], the [[Old Testament]] and the [[New Testament]], as the [[Biblical inspiration|inspired]] word of God. The traditional view of inspiration is that God worked through human authors so that what they produced was what God wished to communicate. The Greek word referring to inspiration in {{bibleverse|2Timothy|3:16||2 Timothy 3:16}} is ''theopneustos'', which literally means "God-breathed".<ref>{{cite book |title=Hermeneutics: Principles and Processes of Biblical Interpretation |edition=2nd |last=Virkler |first=Henry A. |editor-last=Ayayo |editor-first=Karelynne Gerber |year=2007 |publisher=Baker |location=Grand Rapids, MI |isbn=978-0-8010-3138-0 |page=21}}</ref>

Some believe that divine inspiration makes present Bibles [[Biblical inerrancy|inerrant]], while others claim inerrancy for the Bible in its original manuscripts, although none of those are extant. Still others maintain that only a particular translation is inerrant, such as the [[King James Version]].<ref>{{cite web|website=[[Catechism of the Catholic Church]]|title=Inspiration and Truth of Sacred Scripture|url=https://www.vatican.va/archive/catechism/p1s1c2a3.htm|archive-url=https://web.archive.org/web/20100909213651/https://www.vatican.va/archive/catechism/p1s1c2a3.htm|archive-date=9 September 2010}}(§&nbsp;105–108)</ref><ref>Second Helvetic Confession, {{usurped|1=[https://web.archive.org/web/20071203120450/https://www.creeds.net/reformed/helvetic/c01.htm ''Of the Holy Scripture Being the True Word of God'']}}</ref><ref>[[Chicago Statement on Biblical Inerrancy]], [https://www.reformed.org/documents/icbi.html ''online text''] {{Webarchive|url=https://web.archive.org/web/19980129093951/https://www.reformed.org/documents/icbi.html |date=29 January 1998}}</ref> Another closely related view is [[biblical infallibility]] or limited inerrancy, which affirms that the Bible is free of error as a guide to salvation, but may include errors on matters such as history, geography, or science.

The canon of the Old Testament accepted by Protestant churches, which is only the [[Tanakh]] (the canon of the [[Hebrew Bible]]), is shorter than that accepted by the Orthodox and Catholic churches which also include the [[deuterocanonical books]] which appear in the [[Septuagint]], the Orthodox canon being slightly larger than the Catholic;<ref>{{cite book| first=S.

{{Main|Catholic theology of Scripture}}
[[File:PonteSantAngeloRom.jpg|thumb|[[St. Peter's Basilica]] viewed from the [[Tiber]]; the [[Vatican Hill]] in the back and [[Castel Sant'Angelo]] in [[Rome]] to the right. Both the basilica and the hill are part of the [[United Nations General Assembly observers|sovereign state]] of [[Vatican City]], the [[Holy See]] of the [[Catholic Church]].]]

In antiquity, two schools of exegesis developed in [[School of Alexandria|Alexandria]] and [[School of Antioch|Antioch]]. The Alexandrian interpretation, exemplified by [[Origen]], tended to read Scripture [[allegory|allegorically]], while the Antiochene interpretation adhered to the literal sense, holding that other meanings (called ''[[theoria]]'') could only be accepted if based on the literal meaning.<ref>Kelly. ''Early Christian Doctrines''. pp. 69–78.</ref>

[[Catholic theology]] distinguishes two senses of scripture: the literal and the spiritual.<ref>Catechism of the Catholic Church, [https://www.vatican.va/archive/catechism/p1s1c2a3.htm#III, ''The Holy Spirit, Interpreter of Scripture'' §&nbsp;115–118]. {{webarchive |url=https://web.archive.org/web/20150325191945/https://www.vatican.va/archive/catechism/p1s1c2a3.htm#III |date=25 March 2015}}</ref>

The ''literal'' sense of understanding scripture is the meaning conveyed by the words of Scripture. The ''spiritual'' sense is further subdivided into:
* The ''allegorical'' sense, which includes [[Typology (theology)|typology]]. An example would be the [[Passage of the Red Sea|parting of the Red Sea]] being understood as a "type" (sign) of baptism.<ref>{{bibleverse|1Cor|10:2}}</ref>
* The ''[[moral]]'' sense, which understands the scripture to contain some ethical teaching.
* The ''[[anagoge|anagogical]]'' sense, which applies to [[eschatology]], eternity and the [[Apocalypse|consummation of the world]].

Regarding [[exegesis]], following the rules of sound interpretation, Catholic theology holds:
* The injunction that all other senses of sacred scripture are based on the ''literal''<ref>Thomas Aquinas, [https://www.newadvent.org/summa/100110.htm "Whether in Holy Scripture a word may have several senses"] {{webarchive|url=https://web.archive.org/web/20060906114843/https://www.newadvent.org/summa/100110.htm |date=6 September 2006}}</ref><ref>''Catechism of the Catholic Church'', [https://www.vatican.va/archive/catechism/p1s1c2a3.htm#III §&nbsp;116] {{webarchive |url=https://web.archive.org/web/20150325191945/https://www.vatican.va/archive/catechism/p1s1c2a3.htm#III |date=25 March 2015}}</ref>
* That the historicity of the Gospels must be absolutely and constantly held<ref>[[Second Vatican Council]], [https://www.vatican.va/archive/hist_councils/ii_vatican_council/documents/vat-ii_const_19651118_dei-verbum_en.html ''Dei Verbum'' (V.19)] {{webarchive |url=https://web.archive.org/web/20140531175312/https://www.vatican.va/archive/hist_councils/ii_vatican_council/documents/vat-ii_const_19651118_dei-verbum_en.html |date=31 May 2014 }}.</ref>
* That scripture must be read within the "living Tradition of the whole Church"<ref>''Catechism of the Catholic Church'', [https://www.vatican.va/archive/catechism/p1s1c2a3.htm#III "The Holy Spirit, Interpreter of Scripture"]. {{Webarchive|url=https://web.archive.org/web/20100609220852/https://www.vatican.va/archive/catechism/p1s1c2a3.htm#III |date=9 June 2010 }}</ref> and
* That "the task of interpretation has been entrusted to the bishops in communion with the successor of Peter, the [[Bishop]] of [[diocese of Rome|Rome]]".<ref>''Catechism of the Catholic Church'', [https://www.vatican.va/archive/catechism/p1s1c2a2.htm#III "The Interpretation of the Heritage of Faith" §&nbsp;85]. {{webarchive |url=https://web.archive.org/web/20150403212113/https://www.vatican.va/archive/catechism/p1s1c2a2.htm#III |date=3 April 2015}}</ref>

Martin Luther believed that without God's help, Scripture would be "enveloped in darkness".<ref name="Foutz" /> He advocated for "one definite and simple understanding of Scripture".<ref name="Foutz">{{cite web |last=Foutz |first=Scott David |url=https://www.quodlibet.net/luther.shtml |archive-url=https://web.archive.org/web/20000414063800/https://www.quodlibet.net/luther.shtml |url-status=dead |archive-date=14 April 2000 |title=Martin Luther and Scripture |publisher=Quodlibet Journal |access-date=16 June 2014}}</ref> [[John Calvin]] wrote, "all who refuse not to follow the Holy Spirit as their guide, find in the Scripture a clear light".<ref>John Calvin,[https://www.ccel.org/ccel/calvin/calcom45.vii.iv.iv.html '' Commentaries on the Catholic Epistles'' 2 Peter 3:14–18]</ref> 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 to obtain salvation and to live a Christian life.<ref>{{cite book|last=Engelder |first=Theodore E.

==== Original intended meaning of Scripture ====
Protestants stress the meaning conveyed by the words of Scripture, the [[historical-grammatical method]].<ref>Sproul. ''Knowing Scripture'', pp. 45–61; Bahnsen, ''[https://www.cmfnow.com/articles/pt173.htm A Reformed Confession Regarding Hermeneutics'' (article 6)''] {{Webarchive|url=https://web.archive.org/web/20141204091801/https://www.cmfnow.com/articles/pt173.htm |date=4 December 2014 }}.''</ref> The historical-grammatical method or grammatico-historical method is an effort in [[Biblical hermeneutics]] to find the intended original meaning in the text.<ref name="Elwell565">{{Cite book |publisher=Baker |isbn=978-0-8010-3413-8 |last=Elwell |first=Walter A. |title=Evangelical Dictionary of Theology |location=Grand Rapids, MI |year=1984 |page=[https://archive.org/details/evangelicaldicti00elwe/page/565 565] |title-link=Evangelical Dictionary of Theology}}</ref> 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.<ref>{{Cite book |last=Johnson |first=Elliott |url=https://archive.org/details/expositoryhermen0000john |title=Expository hermeneutics : an introduction |publisher=Academie Books |year=1990 |isbn=978-0-310-34160-4 |location=Grand Rapids, MI |url-access=registration}}</ref> 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".<ref>{{Cite book |publisher=Zondervan |last=Terry |first=Milton |author-link=Milton Terry|title=Biblical hermeneutics: a treatise on the interpretation of the Old and New Testaments |location=Grand Rapids, MI |year=1974 |page=205}} (1890 edition page 103, [https://books.google.com/books?id=Fy9VAAAAMAAJ&q=%22fundamental+principle%22 view1], [https://books.google.com/books?id=Fy9VAAAAMAAJ&q=%22neglect+this+principle%22 view2])</ref> 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.<ref name="Elwell565" />
Some Protestant interpreters make use of [[Typology (theology)|typology]].<ref>e.g., in his [https://biblehub.com/commentaries/mhcw/matthew/1.htm commentary on Matthew 1] (§III.1). [[Matthew Henry]] interprets the twin sons of Judah, Phares and Zara, as an allegory of the Gentile and [[Jewish Christians]]. For a contemporary treatment, see Glenny, ''[https://www.biblicalstudies.org.uk/article_typology_glenny.html Typology: A Summary Of The Present Evangelical Discussion]''.</ref>

The Eastern Orthodox Church consists of those churches in communion with the [[patriarch]]al sees of the East, such as the [[Ecumenical Patriarch of Constantinople]].<ref>Cross/Livingstone.

The [[Assyrian Church of the East]], with an unbroken patriarchate established in the 17th century, is an independent [[Eastern Christian]] denomination which claims continuity from the [[Church of the East]]—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]].

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 [[Radical Reformation]], which though sometimes protected under ''Acts of Toleration'', do not trace their history back to any state church.

The term ''Protestant'' also refers to any churches which formed later, with either the Magisterial or Radical traditions.

[[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.<ref>{{Cite book

=== Criticism ===
[[File:Bronze statue of Giordano Bruno by Ettore Ferrari , Campo de' Fiori, Roma.jpg|thumb|The monument to [[Giordano Bruno]] in the place he was executed in Rome]]
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., {{Bibleverse||Matthew|15:1–20|NIV}} and {{Bibleverse||Mark|7:1–23|NIV}}).<ref>''International Standard Bible Encyclopedia: E-J'' by Geoffrey W. Bromiley 1982 {{ISBN|0-8028-3782-4}} p. 175</ref> 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.<ref>''Jews and Christians: The Parting of the Ways, A.D. 70 to 135'' by James D.G. Dunn 1999 {{ISBN|0802844987}} pp.&nbsp;112–113</ref> Additionally, a sacrifice to remove sins in advance, for everyone or as a human being, did not fit the Jewish sacrifice ritual; furthermore, [[God in Judaism]] is said to judge people on their deeds instead of their beliefs.<ref>Asher Norman ''Twenty-six Reasons why Jews Don't Believe in Jesus'' Feldheim Publishers 2007 {{ISBN|978-0977193707}} p. 11</ref><ref>Keith Akers ''The Lost Religion of Jesus: Simple Living and Nonviolence in Early Christianity''. Lantern Books 2000 {{ISBN|978-1930051263}} p. 103</ref> 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.<ref>{{cite book|last1=Ferguson|first1=Everett|title=Backgrounds of Early Christianity|url=https://archive.org/details/backgroundsearly00ferg|url-access=limited|year=1993|publisher=William B.

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.<ref>{{cite book|last1=Ferguson|first1=Everett|title=Backgrounds of Early Christianity|url=https://archive.org/details/backgroundsearly00ferg|url-access=limited|year=1993|publisher=William B.

Criticism of Christianity continues to date, e.g. [[Jewish]] and [[Muslim]] theologians criticize the doctrine of the [[Trinity]] held by most Christians, stating that this doctrine in effect assumes that there are three gods, running against the basic tenet of [[monotheism]].<ref>''Christianity: An Introduction'' by Alister E.

=== Apologetics ===
[[File:SummaTheologiae.jpg|upright|thumb|A copy of the ''[[Summa Theologica]]'' by [[Thomas Aquinas]]]]

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".<ref>{{LSJ|a)pologhtiko/s|ἀπολογητικός}}, {{LSJ|a)pologe/omai|ἀπολογέομαι|shortref}}.</ref> Christian apologetics has taken many forms over the centuries, starting with Paul the Apostle. The philosopher [[Thomas Aquinas]] presented five arguments for God's existence in the ''[[Summa Theologica]]'', while his ''[[Summa contra Gentiles]]'' was a major apologetic work.<ref>{{cite book|last=Dulles|first=Avery Robert Cardinal|title=A History of Apologetics |year=2005 |publisher=Ignatius |location=San Francisco|isbn=978-0-89870-933-9|page=120}}</ref><ref>{{cite book|title=Classical Readings in Christian Apologetics |year=1983 |publisher=Zondervan |location=Grand Rapids |isbn=978-0-310-45641-4 |editor-first=L. Russ |editor-last=Bush|page=275}}</ref> 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.<ref>{{cite web|url=https://www.chesterton.org/why-i-believe-in-christianity/|title=Why I Believe in Christianity – Society of Gilbert Keith Chesterton|date=6 December 2010}}</ref><ref>{{cite journal|author=Hauser, Chris (History major, Dartmouth College class of 2014)|date=Fall 2011|title=Faith and Paradox: G.K.

John Lennox, a mathematician at the University of Oxford, tells us that 'even if the non-believers don't like it, the Big Bang fits in exactly with the Christian narrative of creation'. ... William Lane Craig is another who claims that the Biblical account is corroborated by Big Bang cosmology. Lane Craig also claims that there is a prior ''proof'' that there is a God who created this universe.}}</ref> [[Creationist apologetics]] is apologetics that aims to defend [[creationism]].
