Nicene Christianity is a set of Christian doctrinal traditions which reflect the Nicene Creed, which was formulatedat the First Council of Nicaea in AD 325 and amended at the First Council of Constantinople in AD 381.
Christianity is an Abrahamic monotheistic religion based on the life and teachings of Jesus of Nazareth. Its adherents, known as Christians, believe that Jesus is the Christ, the Son of God, and the savior of all people, whose coming as the Messiah was prophesied in the Hebrew Scriptures of Judaism, called the Old Testament in Christianity, and chronicled in the New Testament. It is the world's largest religion with over 2.4 billion followers.
The Nicene Creed is a statement of belief widely used in Christian liturgy. It is called Nicene because it was originally adopted in the city of Nicaea by the First Council of Nicaea in 325. In 381, it was amended at the First Council of Constantinople, and the amended form is referred to as the Nicene or the Niceno-Constantinopolitan Creed.
The First Council of Nicaea was a council of Christian bishops convened in the Bithynian city of Nicaea by the Roman Emperor Constantine I in AD 325.
The main rival doctrine of Nicene Christianity at the time of Nicaea, Arianism, became eclipsed during the 7th century AD with the conversion of the Gothic kingdoms to Nicene Christianity. The main points of dissent centered on Christology. Nicene Christianity regards Christ as divine and co-eternal with God the Father, while Arian Christianity treated Christ as the first created being and inferior to God the Father. Other non-Nicene currents have been considered heresies since the early medieval period. [ failed verification ]
Arianism is a nontrinitarian Christological doctrine which asserts the belief that Jesus Christ is the Son of God who was begotten by God the Father at a point in time, a creature distinct from the Father and is therefore subordinate to him, but the Son is also God. Arian teachings were first attributed to Arius, a Christian presbyter in Alexandria of Egypt. The term "Arian" is derived from the name Arius; and like "Christian", it was not a self-chosen designation but bestowed by hostile opponents—and never accepted by those on whom it had been imposed. The nature of Arius's teaching and his supporters were opposed to the theological views held by Homoousian Christians, regarding the nature of the Trinity and the nature of Christ. The Arian concept of Christ is based on the belief that the Son of God did not always exist but was begotten within time by God the Father.
The Goths were an East Germanic people, two of whose branches, the Visigoths and the Ostrogoths, played an important role in the fall of the Western Roman Empire through the long series of Gothic Wars and in the emergence of Medieval Europe. The Goths dominated a vast area, which at its peak under the Germanic king Ermanaric and his sub-king Athanaric possibly extended all the way from the Danube to the Don, and from the Baltic Sea to the Black Sea.
Christology, literally "the understanding of Christ," is the study of the nature (person) and work of Jesus Christ. It studies Jesus Christ's humanity and divinity, and the relation between these two aspects; and the role he plays in salvation.
Present-day mainstream Christian Churches - including all of the Catholic, Eastern Orthodox, Oriental Orthodox, Assyrian and Ancient Churches, Lutheran and Anglican churches, together with most Protestant denominations - adhere to the Nicene Creed and thus exemplify Nicene Christianity.
The Christian Church, also called the holy catholic church, is a Protestant ecclesiological concept of a church invisible comprising all Christians. In this understanding, "Christian Church" or "catholic church" does not refer to a particular Christian denomination but to the "body" of all "believers", both defined in various ways. Other Christian traditions believe that these terms apply only to a specific concrete Christian institution, such as the Catholic Church, the Eastern Orthodox Church, the Oriental Orthodox Churches, or the Assyrian Church of the East; or to a group of institutions, as in the branch theory taught by some Anglicans.
The Catholic Church, also known as the Roman Catholic Church, is the largest Christian church, with approximately 1.3 billion baptised Catholics worldwide as of 2017. As the world's oldest and largest continuously functioning international institution, it has played a prominent role in the history and development of Western civilisation. The church is headed by the Bishop of Rome, known as the pope. Its central administration, the Holy See, is in the Vatican City, an enclave within the city of Rome in Italy.
The Eastern Orthodox Church, officially the Orthodox Catholic Church, is the second-largest Christian church, with approximately 260 million baptised members. It operates as a communion of autocephalous churches, each governed by its bishops in local synods, although roughly half of Eastern Orthodox Christians live in Russia. The church has no central doctrinal or governmental authority analogous to the Bishop of Rome, but the Ecumenical Patriarch of Constantinople is recognised by all as primus inter pares of the bishops. As one of the oldest surviving religious institutions in the world, the Eastern Orthodox Church has played a prominent role in the history and culture of Eastern and Southeastern Europe, the Caucasus, and the Near East.
Chalcedonian Christianity forms a large subset of Nicene Christianity. In addition to subscribing to the Nicene Creed, Chalcedonian Christians also subscribe to the decisions of the First Council of Ephesus in AD 431 and of the Council of Chalcedon in AD 451. The great majority of Nicene Christians are also Chalcedonian Christians. However, some portions of Eastern Christianity such as the Oriental Orthodox Churches and historically the Church of the East adhere to the Nicene Creed but not to the Chalcedonian Definition and are therefore part of Nicene Christianity but non-Chalcedonian. (The Church of the East also rejected the outcome of the 431 Council of Ephesus.)
Chalcedonian Christianity refers to the Christian denominations adhering to the christological definitions and ecclesiological resolutions of the Council of Chalcedon, the Fourth Ecumenical Council held in 451. Chalcedonian Christians follow the Definition of Chalcedon, a religious doctrine concerning the divine and human natures of Jesus Christ. The great majority of Christian communions and confessions in the 21st century are Chalcedonian, but from the 5th to the 8th centuries the ascendancy of Chalcedonian Christology was not always certain.
In mathematics, a set A is a subset of a set B, or equivalently B is a superset of A, if A is "contained" inside B, that is, all elements of A are also elements of B. A and B may coincide. The relationship of one set being a subset of another is called inclusion or sometimes containment. A is a subset of B may also be expressed as B includes A; or A is included in B.
The Council of Chalcedon was a church council held from 8 October to 1 November, 451, at Chalcedon, a town of Bithynia in Asia Minor. The Council was called by Emperor Marcian to set aside the 449 Second Council of Ephesus. Its principal purpose was to assert the orthodox catholic doctrine against the heresy of Eutyches and the Monophysites, although ecclesiastical discipline and jurisdiction also occupied the council's attention.
Examples of non-Nicene Christianity today include the various either Protestant or non-Protestant non-trinitarian groups like most of the Latter Day Saint movement (with the exception of the Nicene Mormon group the Community of Christ - formerly known as the Reorganized Church of Jesus Christ of Latter Day Saints), the Unitarian Church of Transylvania and the Oneness Pentecostals.
Nontrinitarianism is a form of Christianity that rejects the mainstream Christian doctrine of the Trinity—the teaching that God is three distinct hypostases or persons who are coeternal, coequal, and indivisibly united in one being, or essence. Certain religious groups that emerged during the Protestant Reformation have historically been known as antitrinitarian, but are not considered Protestant in popular discourse due to their nontrinitarian nature.
The Latter Day Saint movement is the collection of independent church groups that trace their origins to a Christian Restorationist movement founded by Joseph Smith in the late 1820s.
Community of Christ, known from 1872 to 2001 as the Reorganized Church of Jesus Christ of Latter Day Saints (RLDS), is an American-based international church, and is the second-largest denomination in the Latter Day Saint movement. The church reports 250,000 members in 1,100 congregations in 59 countries. The church traces its origins to Joseph Smith's establishment of the Church of Christ on April 6, 1830. A group of members including his elder son Joseph Smith III formally established the current church on April 6, 1860 in the aftermath of the 1844 death of Joseph Smith.
The Church Fathers, Early Church Fathers, Christian Fathers, or Fathers of the Church were ancient and influential Christian theologians and writers. There is no definitive list. The era of these scholars who set the theological and scholarly foundations of Christianity largely ended by AD 700.
With the Edict of Thessalonica in 380 AD, Emperor Theodosius I made Nicene Christianity the Empire's state religion. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church each claim to stand in continuity with the church to which Theodosius granted recognition, but do not look on it as specific to the Roman Empire.
The Chalcedonian Definition was adopted at the Council of Chalcedon in AD 451. Chalcedon was an early centre of Christianity located in Asia Minor. The council was the fourth of the Ecumenical Councils that are accepted by Chalcedonian churches which include the Eastern Orthodox, Catholic, and most Protestant churches. It was the first council not to be recognised by any Oriental Orthodox church; these churches may be classified as non-Chalcedonian.
The Coptic Orthodox Church of Alexandria is an Oriental Orthodox Christian church based in Egypt, Africa and the Middle East. The head of the Church and the See of Alexandria is the Patriarch of Alexandria on the Holy See of Saint Mark, who also carries the title of Coptic Pope. The See of Alexandria is titular, and today the Coptic Pope presides from Saint Mark's Coptic Orthodox Cathedral in the Abbassia District in Cairo. The church follows the Alexandrian Rite for its liturgy, prayer and devotional patrimony. With 18–22 million members worldwide, whereof about 15 to 20 million are in Egypt, it is the country's largest Christian church.
An ecumenical council is a conference of ecclesiastical dignitaries and theological experts convened to discuss and settle matters of Church doctrine and practice in which those entitled to vote are convoked from the whole world (oikoumene) and which secures the approbation of the whole Church.
The First Council of Constantinople was a council of Christian bishops convened in Constantinople in AD 381 by the Roman Emperor Theodosius I. This second ecumenical council, an effort to attain consensus in the church through an assembly representing all of Christendom, except for the Western Church, confirmed the Nicene Creed, expanding the doctrine thereof to produce the Niceno-Constantinopolitan Creed, and dealt with sundry other matters. It met from May to July 381 in the Church of Hagia Irene and was affirmed as ecumenical in 451 at the Council of Chalcedon.
Monophysitism is the Christological position that, after the union of the divine and the human in the historical incarnation, Jesus Christ, as the incarnation of the eternal Son or Word (Logos) of God, had only a single "nature" which was either divine or a synthesis of divine and human. Monophysitism is contrasted to dyophysitism which maintains that Christ maintained two natures, one divine and one human, after the incarnation.
Syriac Christianity is the form of Eastern Christianity whose formative theological writings and traditional liturgy are expressed in the Syriac language. Syriac Christianity consists of two liturgical rites, the East Syriac Rite and the West Syriac Rite. The main Anaphora of the East Syriac tradition is the Holy Qurbana of Saints Addai and Mari, while that of the West Syriac tradition is the Divine Liturgy of Saint James.
Non-Chalcedonianism is a religious doctrine of those Christian churches that do not accept the Confession of Chalcedon as defined at the ecumenical Council of Chalcedon in 451. The doctrine contrasts with Chalcedonian Christianity, which accepts the doctrines of the first seven Ecumenical Councils. Some Christian denominations do not accept the Confession of Chalcedon, for varying reasons, but accept the doctrines of the previous council at the Council of Ephesus in 431.
Patristics or patrology is the study of the early Christian writers who are designated Church Fathers. The names derive from the combined forms of Latin pater and Greek patḗr (father). The period is generally considered to run from the end of New Testament times or end of the Apostolic Age to either AD 451 or to the Second Council of Nicaea in 787.
Homoousion is a Christian theological term, most notably used in the Nicene Creed for describing Jesus as "same in being" or "same in essence" with God the Father. The same term was later also applied to the Holy Spirit in order to designate him as being "same in essence" with the Father and the Son. Those notions became cornerstones of theology in Nicene Christianity, and also represent one of the most important theological concepts within the Trinitarian doctrinal understanding of God.
The Second Council of Ephesus was a Christological church synod in 449 AD convened by Emperor Theodosius II under the presidency of Pope Dioscorus I of Alexandria. It was intended to be an ecumenical council, and it is accepted as such by the miaphysite churches but was rejected by the Chalcedonian dyophysites. It was explicitly repudiated by the next council, the Council of Chalcedon of 451, recognised as the fourth ecumenical council by Chalcedonian Christians, and it was named the Latrocinium or "Robber Council" by Pope Leo I. The Chalcedonian churches, particularly the Roman Catholic and Eastern Orthodox communions, continue to accept this designation, while the Oriental Orthodox repudiate it.
Coptic history is part of history of Egypt that begins with the introduction of Christianity in Egypt in the 1st century AD during the Roman period, and covers the history of the Copts to the present day. Many of the historic items related to Coptic Christianity are on display in many museums around the world and a large number is in the Coptic Museum in Coptic Cairo.
In the history of Christianity, the first seven ecumenical councils include the following: the First Council of Nicaea in 325, the First Council of Constantinople in 381, the Council of Ephesus in 431, the Council of Chalcedon in 451, the Second Council of Constantinople in 553, the Third Council of Constantinople from 680–681 and finally, the Second Council of Nicaea in 787.
Oriental Orthodoxy is the communion of Eastern Christian Churches that recognize only three ecumenical councils — the First Council of Nicaea, the First Council of Constantinople and the Council of Ephesus. They reject the dogmatic definitions of the Council of Chalcedon. Hence, these Churches are also called Old Oriental Churches or Non-Chalcedonian Churches.
Oriental Orthodoxy is the communion of Christian churches that adheres to Miaphysite Christology and theology, with 60 to 70 million members worldwide. As one of the oldest religious institutions in the world, it has played a prominent role in the history and culture of Armenia, Egypt, Eritrea, Ethiopia, Sudan and parts of the Middle East and India. An Eastern Christian communion of autocephalous churches, its bishops are equal by virtue of episcopal ordination, and its doctrines can be summarized in that the communion recognizes the validity of only the first three ecumenical councils.
In the 5th century in Christianity, there were many developments which led to further fracturing of the State church of the Roman Empire. Emperor Theodosius II called two synods in Ephesus, one in 431 and one in 449, that addressed the teachings of Patriarch of Constantinople Nestorius and similar teachings. Nestorius had taught that Christ's divine and human nature were distinct persons, and hence Mary was the mother of Christ but not the mother of God. The Council rejected Nestorius' view causing many churches, centered on the School of Edessa, to a Nestorian break with the imperial church. Persecuted within the Roman Empire, many Nestorians fled to Persia and joined the Sassanid Church thereby making it a center of Nestorianism. By the end of the 5th century, the global Christian population was estimated at 10-11 million. In 451 the Council of Chalcedon was held to clarify the issue further. The council ultimately stated that Christ's divine and human nature were separate but both part of a single entity, a viewpoint rejected by many churches who called themselves miaphysites. The resulting schism created a communion of churches, including the Armenian, Syrian, and Egyptian churches, that is today known as Oriental Orthodoxy. In spite of these schisms, however, the imperial church still came to represent the majority of Christians within the Roman Empire.
Christianity in late antiquity traces Christianity during the Christian Roman Empire – the period from the rise of Christianity under Emperor Constantine, until the fall of the Western Roman Empire. The end-date of this period varies because the transition to the sub-Roman period occurred gradually and at different times in different areas. One may generally date late ancient Christianity as lasting to the late 6th century and the re-conquests under Justinian of the Byzantine Empire, though a more traditional end-date is 476, the year in which Odoacer deposed Romulus Augustus, traditionally considered the last western emperor.
