I suspect that even the most enthusiastic accounts err on the downside, and that Christianity will have become a Sino-centric religion two generations from now.

Part of the clergy escaped the Soviet persecutions by fleeing abroad, where they founded an independent church in exile, which reunified with the Russian one in 2007.

Before and after the October Revolution of 7 November 1917 (October 25 Old Calendar) there was a movement within the Soviet Union to unite all of the people of the world under Communist rule (see Communist International). This included the Eastern European bloc countries as well as the Balkan States. Since some of these Slavic states tied their ethnic heritage to their ethnic churches, both the peoples and their church where targeted by the Soviet. The Soviets' official religious stance was one of "religious freedom or tolerance", though the state established atheism as the only scientific truth. Criticism of atheism was strictly forbidden and sometimes lead to imprisonment.

The Soviet Union was the first state to have as an ideological objective the elimination of religion. Toward that end, the Communist regime confiscated church property, ridiculed religion, harassed believers, and propagated atheism in the schools. Actions toward particular religions, however, were determined by State interests, and most organised religions were never outlawed.

The main target of the anti-religious campaign in the 1920s and 1930s was the Russian Orthodox Church, which had the largest number of faithful.

In the period between 1927 and 1940, the number of Orthodox Churches in the Russian Republic fell from 29,584 to less than 500. Between 1917 and 1940, 130,000 Orthodox priests were arrested.

 and its following years, is largely responsible for the spread of secularism. For example the Gallup International Millennium Survey showed that only about one sixth of Europeans attend regular religious services, less than half gave God "high importance", and only about 40% believe in a "personal God". Nevertheless the large majority considered that they "belong" to a religious denomination

. Numbers show that the "de-Christianization" of Europe has slowly begun to swing in the opposite direction. Renewal in certain quarters of the Anglican church, as well as in pockets of Protestantism on the continent attest to this initial reversal of the secularization of Europe, the continent in which Christianity originally took its strongest roots and world expansion.

In North America, South America and Australia, the other three continents where Christianity is the dominant professed religion, religious observance is much higher than in Europe. At the same time, these regions are often seen by other nations as being uptight and "Victorian", in their social mores.

South America, historically Catholic, has experienced a large Evangelical and Pentecostal infusion in the 20th century due to the influx of Christian missionaries from abroad. For example: Brazil, South America's largest country, is the largest Catholic country in the world, and at the same time is the largest Evangelical country in the world (based on population). Some of the largest Christian congregations in the world are found in Brazil.

Evangelicalism

The 1950s saw a boom in the Evangelical church in America. The post–World War II prosperity experienced in the U.S. also had its effects on the church. Although simplistically referred to as "morphological fundamentalism", the phrase nonetheless does accurately describe the physical developments experienced. Church buildings were erected in large numbers, and the Evangelical church's activities grew along with this expansive physical growth.

In the U.S. and elsewhere in the world, there has been a marked rise in the evangelical

 was the faster growing sector of the American church. Liberal wings of denominations were on the rise, and a considerable number of seminaries held and taught from a liberal perspective as well. In the post–World war II era, the trend began to swing back towards the conservative camp in America's seminaries and church structures. Those entering seminaries and other postgraduate theologically related programs have shown more conservative leanings than their average predecessors.

The neo-Evangelical push of the 1940s and 1950s produced a movement that continues to have wide influence. In the southern U.S., the more moderate neo-Evangelicals, represented by leaders such as Billy Graham

, have managed to maintain credibility in the eyes of many fundamentalists, as well as to gain stature as a more moderate Evangelical.

Evangelicalism is not a single, monolithic entity. The Evangelical churches and their adherents cannot be easily stereotyped. Most are not fundamentalist, in the narrow sense that this term has come to represent; though many still refer to themselves as such. There have always been diverse views on issues, such as openness to cooperation with non-Evangelicals, the applicability of the Bible to political choices and social or scientific issues, and even the limited inerrancy of the Bible.

However, the movement has managed in an informal way, to reserve the name Evangelical for those who adhere to an historic Christian faith, a paleo-orthodoxy, as some have put it. Those who call themselves "moderate evangelicals"(although considered conservative in relation to society as a whole) still hold fast to the fundamentals of the historic Christian faith. Even "Liberal" Evangelicals label themselves as such not so much in terms of their theology, but rather to advertise that they are progressive in their civic, social, or scientific perspective.

 which had developed in the late 19C. The Pentecostal revival movement began, out of a passion for more power and a greater outpouring of the Spirit. In 1902, the American evangelists Reuben Archer Torrey and Charles M. Alexander conducted meetings in Melbourne, Australia, resulting in more than 8,000 converts. News of this revival travelled fast, igniting a passion for prayer and an expectation that God would work in similar ways elsewhere.

Torrey and Alexander were involved in the beginnings of the great Welsh revival (1904) which led Jessie Penn-Lewis

, in Los Angeles.

Another noteworthy development in 20th-century Christianity was the rise of the modern Pentecostal movement. Although its roots predate the year 1900, its actual birth is commonly attributed to the 20th century. Sprung from Methodist and Wesleyan roots, it arose out of the meetings at an urban mission on Azusa Street in Los Angeles. From there it spread around the world, carried by those who experienced what they believed to be miraculous moves of God there. These Pentecost-like manifestations have steadily been in evidence throughout the history of Christianity—such as seen in the two Great Awakenings that started in the United States. However, Azusa Street is widely accepted as the fount of the modern Pentecostal movement. Pentecostalism, which in turn birthed the Charismatic movement

 within already established denominations, continues to be an important force in western Christianity.

In reaction to these developments, Christian fundamentalism was a movement to reject the radical influences of philosophical humanism, as this was affecting the Christian religion. Especially targeting critical approaches to the interpretation of the Bible, and trying to blockade the inroads made into their churches by atheistic scientific assumptions, the fundamentalists began to appear in various denominations as numerous independent movements of resistance to the drift away from historic Christianity. Over time, the Fundamentalist Evangelical movement has divided into two main wings, with the label Fundamentalist following one branch, while Evangelical has become the preferred banner of the more moderate movement. Although both movements primarily originated in the English speaking world, the majority of Evangelicals now live elsewhere in the world.

Protestant ecumenism

Ecumenical movements within Protestantism have focused on determining a list of doctrines and practices essential to being Christian and thus extending to all groups which fulfil these basic criteria a (more or less) co-equal status, with perhaps one's own group still retaining a "first among equal" standing. This process involved a redefinition of the idea of "the Church" from traditional theology. This ecclesiology, known as denominationalism, contends that each group (which fulfils the essential criteria of "being Christian") is a sub-group of a greater "Christian Church", itself a purely abstract concept with no direct representation, i.e., no group, or "denomination", claims to be "the Church." Obviously, this ecclesiology is at variance with other groups that indeed consider themselves to be "the Church." The "essential criteria" generally consist of belief in the Trinity, belief that Jesus Christ is the only way to have forgiveness and eternal life, and that He died and rose again bodily.

, the Roman Catholic Church's teaching on the authority of the Pope, bishops and councils was further elaborated. Vatican II sought to correct the unbalanced ecclesiology left behind by Vatican I. The result is the body of teaching about the papacy and episcopacy contained in the Dogmatic Constitution on the Church, Lumen Gentium.

Vatican II reaffirmed everything Vatican I taught about papal primacy and infallibility, but it added important points about bishops. Bishops, it says, are not "vicars of the Roman Pontiff." Rather, in governing their local churches they are "vicars and legates of Christ". Together, they form a body, a "college", whose head is the pope. This episcopal college is responsible for the well-being of the Universal Church. Here in a nutshell are the basic elements of the Council's much-discussed communio ecclesiology, which affirms the importance of local churches and the doctrine of collegiality.

In a key passage about collegiality, Vatican II teaches: "The order of bishops is the successor to the college of the apostles in their role as teachers and pastors, and in it the apostolic college is perpetuated. Together with their head, the Supreme Pontiff, and never apart from him, they have supreme and full authority over the Universal Church; but this power cannot be exercised without the agreement of the Roman Pontiff". Much of the present discussion of papal primacy is concerned with exploring the implications of this passage.

Chapter 3 of the dogmatic constitution on the Church of Vatican Council I (Pastor aeternus) is the principal document of the Magisterium about the content and nature of the primatial power of the Roman Pontiff. Chapter 4 is a development and defining of one particular characteristic of this primatial power, namely the Pope's supreme teaching authority, i.e. when the Pope speaks ex cathedra he teaches the doctrine of the faith infallibly.

Modern response to Protestantism

Well into the twentieth century, Catholics still defined Protestants as heretics, even if no longer resorting to persecution. The Catholic Church considers for example "sola scriptura
Sola scriptura
Sola scriptura is the doctrine that the Bible contains all knowledge necessary for salvation and holiness. Consequently, sola scriptura demands that only those doctrines are to be admitted or confessed that are found directly within or indirectly by using valid logical deduction or valid...

" heretical, the belief that the Bible is the only infallible authority for Christian faith, with the demand that all other authorities are subordinate to the Bible.

In the second half of the century, especially in the wake of Vatican II, Catholic usage began favored referring to Protestants as "separated brethren" rather than "heretics." The latter is still on occasion used vis-a-vis Catholics who abandon their Church to join a Protestant denomination.

Emigration to the West

One of the most striking developments in modern historical Orthodoxy is the dispersion of Orthodox Christians to the West. Emigration from Greece and the Near East in the last hundred years has created a sizable Orthodox diaspora in Western Europe, North and South America, and Australia. In addition, the Bolshevik Revolution forced thousands of Russian exiles westward. As a result, Orthodoxy's traditional frontiers have been profoundly modified. Millions of Orthodox are no longer geographically "eastern" since they live permanently in their newly adopted countries in the West. Nonetheless, they remain Eastern Orthodox in their faith and practice. Virtually all the Orthodox nationalities — Greek, Arab, Russian

Russian Orthodoxy

By 1957 about 22,000 Russian Orthodox churches had become active. But in 1959 Nikita Khrushchev initiated his own campaign against the Russian Orthodox Church and forced the closure of about 12,000 churches. By 1985 fewer than 7,000 churches remained active. Members of the church hierarchy were jailed or forced out, their places taken by docile clergy, many of whom had ties with the KGB.

In the Soviet Union, in addition to the methodical closing and destruction of churches, the charitable and social work formerly done by ecclesiastical authorities was taken over by the state. As with all private property, Church owned property was confiscated into public use. The few places of worship left to the Church were legally viewed as state property which the government permitted the church to use. After the advent of state funded universal education, the Church was not permitted to carry on educational, instructional activity for children. For adults, only training for church-related occupations was allowed. Outside of sermons during the celebration of the divine liturgy it could not instruct or evangelise to the faithful or its youth. Catechism classes, religious schools, study groups, Sunday schools and religious publications were all illegal and or banned. This persecution continued, even after the death of Stalin until the dissolution of the Soviet Union

), which means "the inhabited world", but more figuratively something like "universal oneness." The movement can be distinguished into Catholic and Protestant movements, with the latter characterised by a redefined ecclesiology of "denominationalism" (which the Catholic Church, among others, rejects).

Over the last century, a number of moves have been made to reconcile the schism between the Catholic Church and the Eastern Orthodox churches
East-West Schism
The East–West Schism of 1054, sometimes known as the Great Schism, formally divided the State church of the Roman Empire into Eastern and Western branches, which later became known as the Eastern Orthodox Church and the Roman Catholic Church, respectively...

Some of the most difficult questions in relations with the ancient Eastern Churches concern some doctrine (i.e. Filioque, Scholasticism

With respect to Catholic relations with Protestant communities, certain commissions were established to foster dialogue and documents have been produced aimed at identifying points of doctrinal unity, such as the Joint Declaration on the Doctrine of Justification

 in June 1993, the Joint International Commission for the Theological Dialogue between the Roman Catholic Church and the Orthodox Church the delegates of the Eastern Orthodox Churches declared "...and that what has been called 'uniatism' can no longer be accepted either as a method to be followed nor as a model of the unity our Churches are seeking" (section 12 of the document).

At the same time, the Commission stated:
  • Concerning the Eastern Catholic Churches, it is clear that they, as part of the Catholic Communion, have the right to exist and to act in response to the spiritual needs of their faithful.
  • The Oriental Catholic Churches who have desired to re-establish full communion with the See of Rome and have remained faithful to it, have the rights and obligations which are connected with this communion.

The Joint International Commission for Theological Dialogue Between the Catholic Church and the Orthodox Church first met in Rhodes in 1980.

Other moves toward reconciliation

In May 1999, John Paul II was the first pope since the Great Schism to visit an Eastern Orthodox country: Romania
