Orthodoxy in the context of "Creed"

In the history of Christianity, the first seven ecumenical councils are as follows: 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 to 681 and finally, the Second Council of Nicaea in 787.

These seven events represented an attempt by Church leaders to reach an orthodox consensus, restore peace and develop a unified Christendom. Among Eastern Christians the Eastern Orthodox, Oriental Orthodox, and Church of the East (Assyrian) churches and among Western Christians the Roman Catholic, Anglican, Utrecht and Polish National Old Catholic, and some Scandinavian Lutheran churches all trace the legitimacy of their clergy by apostolic succession back to this period and beyond, to the earlier period referred to as the Early Church.

Christianity in Azerbaijan is a minority religion. Christians, estimated between 280,000 and 450,000 (3.1%–4.8%), are mostly Russian and Georgian Orthodox. There is also a small Protestant Christian community which mostly came from Muslim backgrounds. Due to the very hostile relations between Azerbaijan and Armenia, Armenian Christians have practically entirely fled the country, and so the Christians in Azerbaijan are members of various other groups, mostly Russians and Georgians, but also some ethnic Azerbaijani Christians.

Perversion is a form of human behavior which is far from what is considered to be orthodox or normal. Although the term perversion can refer to a variety of forms of deviation, it is most often used to describe sexual behaviors that are considered particularly abnormal, repulsive or obsessive. Perversion usually differs from "deviant behavior", in that the latter covers areas of behavior (such as petty crime) for which perversion would be too strong a term. It is often considered derogatory, and, in psychological literature, the term paraphilia has been used as a replacement for most forms of sexual perversion, though this clinical term is controversial, and deviation is sometimes used in its place.

In the year before the First Council of Constantinople in 381, Nicene Christianity became the official religion of the Roman Empire when Theodosius I, emperor of the East, Gratian, emperor of the West, and Gratian's junior co-ruler Valentinian II issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy, as defined by the Council of Nicea, as the Roman Empire's state religion. Historians refer to this state-sponsored church using a variety of terms: the catholic church, the orthodox church, the imperial church, the Roman church, or the Byzantine church, with some also used for wider communions extending beyond the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church all claim to stand in continuity from the Nicene Christian church to which Theodosius granted recognition. Political differences between the Eastern Roman Empire and the Persian Sassanid Empire led to the separation of the Church of the East in 424. A doctrinal split within the imperial church led to the independence of early Oriental Orthodoxy, while the fall of the Western Roman Empire initiated the gradual separation between Eastern and Western Christianity, culminating in the East-West schism of 1054. The Western Church evolved into the Latin Catholic Church while the Eastern Church that remained under the patronage of the Eastern empire and evolved into the Greek Orthodox Church.

Earlier in the 4th century, following the Diocletianic Persecution of 303–313 and the Donatist controversy that arose in consequence, Constantine the Great had convened councils of bishops to define the orthodoxy of the Christian faith and to expand on earlier Christian councils. A series of ecumenical councils convened by successive Roman emperors met during the 4th and the 5th centuries, but Christianity continued to suffer rifts and schisms surrounding the theological and christological doctrines of Arianism, Nestorianism, Miaphysitism, and Dyophysitism. In the 5th century, the Western Roman Empire decayed as a polity; invaders sacked Rome in 410 and in 455, and Odoacer, an Arian barbarian warlord, forced Romulus Augustus, the last nominal Western Emperor, to abdicate in 476. However, apart from the aforementioned schisms, the church as an institution persisted in communion, if not without tension, between the East and West. In the 6th century, the Byzantine armies of the Byzantine Emperor Justinian I recovered Italy and other regions of the Western Mediterranean shore. The Byzantine Empire soon lost most of these gains, but it held Rome, as part of the Exarchate of Ravenna, until 751, a period known in church history as the Byzantine Papacy. The early Muslim conquests of the 7th–9th centuries would begin a process of converting most of the then-Christian world in the Levant, Middle East, North Africa, regions of Southern Italy and the Iberian Peninsula to Islam, severely restricting the reach both of the Byzantine Empire and of its church. Christian missionary activity directed from the capital of Constantinople did not lead to a lasting expansion of the formal link between the church and the Byzantine emperor, since areas outside the Byzantine Empire's political and military control set up their own distinct churches, as in the case of Bulgaria in 919.

In religion, heterodoxy (from Ancient Greek: héteros, 'other, another, different' + dóxa, 'popular belief') means "any opinions or doctrines at variance with an official or orthodox position".

Heterodoxy is also an ecclesiastical jargon term, defined in various ways by different religions and churches. For example, in some groups, heterodoxy may describe beliefs that differ from strictly orthodox views but that fall short either of formal or of material heresy.

Heaven, or the Heavens, is a common religious cosmological or supernatural place where beings such as deities, angels, souls, saints, or venerated ancestors are said to originate, be enthroned, or reside. According to the beliefs of some religions, heavenly beings can descend to Earth or incarnate and earthly beings can ascend to Heaven in the afterlife or, in exceptional cases, enter Heaven without dying.

Heaven is often described as a "highest place", the holiest place, a paradise, in contrast to Hell or the Underworld or the "low places" and universally or conditionally accessible by earthly beings according to various standards of divinity, goodness, piety, faith, or other virtues or right beliefs or simply divine will. Some believe in the possibility of a heaven on Earth in a world to come.

Political correctness (adjectivally "politically correct"; commonly abbreviated to P.C.) is a term used to describe language, policies, or measures that are intended to avoid perceived offense or disadvantage to members of particular groups in society. Since the late 1980s, the term has been used to describe a preference for inclusive language and avoidance of language or behavior that can be seen as excluding, marginalizing, or insulting to groups of people disadvantaged or discriminated against, particularly groups defined by ethnicity, sex, gender, sexual orientation, or disability. In public discourse and the media, the term’s use is generally pejorative, with an implication that these policies are excessive or unwarranted. It can also be humorous, or ironic in nature.

The phrase politically correct first appeared in the 1930s, when it was used to describe dogmatic adherence to ideology in totalitarian regimes, such as Nazi Germany and Soviet Russia. Early usage of the term politically correct by leftists in the 1970s and 1980s was as self-critical satire; usage was ironic, rather than a name for a serious political movement. It was considered an in-joke among leftists used to satirise those who were too rigid in their adherence to political orthodoxy. The modern pejorative usage of the term emerged from conservative criticism of the New Left in the late 20th century, with many describing it as a form of censorship.

A cathedral is a church that contains the cathedra (Greek for 'seat') of a bishop, thus serving as the central church of a diocese, conference, or episcopate. Churches with the function of "cathedral" are usually specific to those Christian denominations with an episcopal hierarchy, such as the Catholic, Eastern Orthodox, Anglican, and some Lutheran churches. Church buildings embodying the functions of a cathedral first appeared in Italy, Gaul, Spain, and North Africa in the 4th century, but cathedrals did not become universal within the Western Catholic Church until the 12th century, by which time they had developed architectural forms, institutional structures, and legal identities distinct from parish churches, monastic churches, and episcopal residences. The cathedral is more important in the hierarchy than the church because it is from the cathedral that the bishop governs the area under his or her administrative authority.

Following the Protestant Reformation, the Christian church in several parts of Western Europe, such as Scotland, the Netherlands, certain Swiss Cantons and parts of Germany, adopted a presbyterian polity that did away with bishops altogether. Where ancient cathedral buildings in these lands are still in use for congregational worship, they generally retain the title and dignity of "cathedral", maintaining and developing distinct cathedral functions, but void of hierarchical supremacy. From the 16th century onwards, but especially since the 19th century, churches originating in Western Europe have undertaken vigorous programmes of missionary activity, leading to the founding of large numbers of new dioceses with associated cathedral establishments of varying forms in Asia, Africa, Australasia, Oceania and the Americas. In addition, both the Catholic Church and Orthodox churches have formed new dioceses within formerly Protestant lands for converts and migrant co-religionists. Consequently, it is not uncommon to find Christians in a single city being served by three or more cathedrals of differing denominations. For example, London is home to the Anglican St Paul’s Cathedral, the Catholic Westminster Cathedral & St George's Cathedral, and several Eastern Orthodox cathedrals serving different national communities.[1]

A calendar date is a reference to a particular day, represented within a calendar system, enabling a specific day to be unambiguously identified. Simple math can be performed between dates; commonly, the number of days between two dates may be calculated, e.g., "25 December 2025" is ten days after "15 December 2025". The date of a particular event depends on the time zone used to record it. For example, the air attack on Pearl Harbor that began at 7:48 a.m. local Hawaiian time (HST) on 7 December 1941 is recorded equally as having happened on 8 December at 3:18 a.m. Japan Standard Time (JST).

A particular day may be assigned a different nominal date according to the calendar used. The de facto standard for recording dates worldwide is the Gregorian calendar, the world's most widely used civil calendar. Many cultures use religious calendars such as the Gregorian (Western Christendom, AD), the Julian calendar (Eastern Christendom, AD), Hebrew calendar (Judaism, AM), the Hijri calendars (Islam, AH), or any other of the many calendars used around the world. Regnal calendars (that record a date in terms of years since the beginning of the monarch's reign) are also used in some places, for particular purposes.
