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]].[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.
[[Eastern Orthodox theology]] is based on [[holy tradition]] which incorporates the dogmatic decrees of the [[First seven ecumenical councils|seven Ecumenical Councils]], the Scriptures, and the teaching of the [[Church Fathers]]. The church teaches that it is the [[Four Marks of the Church|one, holy, catholic and apostolic]] [[One true church|church]] established by [[Jesus in Christianity|Jesus Christ]] in his [[Great Commission]],[{{Cite web|title=The Orthodox Faith – Volume I – Doctrine and Scripture – The Symbol of Faith – Church|url=https://www.oca.org/orthodoxy/the-orthodox-faith/doctrine-scripture/the-symbol-of-faith/church|access-date=27 July 2020|website=www.oca.org}}] and that its bishops are the successors of Christ's apostles.[{{Cite book|last=Meyendorff|first=John|url=https://books.google.com/books?id=Wo9MwwEACAAJ|title=Byzantine Theology: Historical Trends and Doctrinal Themes |year=1983|publisher=Fordham University Press}}] It maintains that it practises the original Christian faith, as passed down by holy tradition.

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).

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]].

In 1521, the [[Edict of Worms]] condemned [[Martin Luther]] 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 [[Reformation]]. Prominent Reformers included Martin Luther, [[Huldrych Zwingli]], and [[John Calvin]]. The 1529 [[Protestation at Speyer]] against being excommunicated gave this party the name [[Protestantism]]. 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.] The [[Anglicanism|Anglican]] churches descended from the [[Church of England]] and organized in the [[Anglican Communion]].

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.

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. The total Protestant population has reached 1.17 billion in 2024, corresponding to nearly 44% of the world's Christians.[{{cite web |url=https://www.pewforum.org/files/2011/12/Christianity-fullreport-web.pdf |title=Pewforum: Christianity (2010) |access-date=14 May 2014 |archive-url=https://web.archive.org/web/20130805020311/https://www.pewforum.org/files/2011/12/Christianity-fullreport-web.pdf |archive-date=5 August 2013 |url-status=dead}}][{{cite book |last1=Noll |first1=Mark A. |title=Protestantism: A Very Short Introduction |year=2011 |publisher=Oxford University Press |isbn=978-0-19-162013-3 |page=9 |url=https://books.google.com/books?id=1GKBgK00JSsC&q=protestantism+million&pg=PA9}}] The majority of Protestants are members of just a handful of denominational families, i.e. [[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]], [[Reformed Anglican]]s, and [[Presbyterianism|Presbyterians]]),[This branch was first called Calvinism by [[Lutheranism|Lutherans]] who opposed it, and many within the tradition would prefer to use the word ''Reformed''.] and [[Waldensians|Waldensianism]] are the main families of Protestantism.

However, there can be no doubt that the evangelical tradition "per se" has become one of the major components of world Christianity. Evangelicals also constitute sizable minorities in the traditional Protestant and Anglican churches. In regions like Africa and Latin America, the boundaries between "evangelical" and "mainline" are rapidly changing and giving way to new ecclesial realities."]
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 [[creed]]alism of other Christian communities[Confessionalism 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]]".

[[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 Christendom".

Bromiley 1982 {{ISBN|0-8028-3782-4}} p. 175] 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.[''Jews and Christians: The Parting of the Ways, A.D. 70 to 135'' by James D.G. Dunn 1999 {{ISBN|0802844987}} pp. 112–113] 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.[Asher Norman ''Twenty-six Reasons why Jews Don't Believe in Jesus'' Feldheim Publishers 2007 {{ISBN|978-0977193707}} p. 11][Keith Akers ''The Lost Religion of Jesus: Simple Living and Nonviolence in Early Christianity''. Lantern Books 2000 {{ISBN|978-1930051263}} p. 103] 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.[{{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.[{{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 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.[''A Dictionary of Jewish-Christian Relations'' by Edward Kessler, Neil Wenborn 2005 {{ISBN|0521826926}} p. 168] 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.[''The Cambridge Companion to Nietzsche'' by Bernd Magnus, Kathleen Marie Higgins 1996 {{ISBN|0521367670}} pp. 90–93] 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.[''Russell on Religion: Selections from the Writings of Bertrand Russell'' by Bertrand Russell, Stefan Andersson and Louis Greenspan 1999 {{ISBN|0415180910}} pp. 77–87]
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]].[''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".[{{LSJ|a)pologhtiko/s|ἀπολογητικός}}, {{LSJ|a)pologe/omai|ἀπολογέομαι|shortref}}.] 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.[{{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}}][{{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}}] 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.[{{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}}][{{cite journal|author-last1=Hauser|author-first1= 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.}}] [[Creationist apologetics]] are apologetics that aim to defend [[creationism]].
