What it means here
our wording, so the faiths below can be compared — never any tradition's own definitionAuthority handed down in an unbroken chain from the founders.
Every passage on this page is one faith's own phrasing. Sharing an idea is not agreement: Christianity and Traditionalist Catholicism are both here because each says something this word covers, and what they say may flatly contradict each other. The idea is the place they can be set side by side.

Ordination.
The bishop lays on hands in silence — the silence is the ordination, not the words around it. Whether a given bishop stands in an unbroken line from the apostles is the technical question on which Rome, Constantinople, Canterbury and Geneva have refused to recognise each other for centuries.

P
Peter — the rock that cracked.
Denied him three times, was asked three times do you love me, and was given the flock anyway: apostleship as restored failure.

The Church is one, holy, catholic, and apostolic.
Continuity from the apostles through the bishops, with Peter's successor at the center.

The parish and the magisterium.
Geography assigns you a parish; the bishops in communion with Rome teach with authority. Joining: baptism — and for adult converts, a season of formation.

Councils, not one bishop, speak for the Church.
Conciliarity — the standing disagreement with Rome.
Go deeper — context →
A communion of sister churches.
Autocephalous churches — Greek, Russian, Antiochian, and more — one faith with no single head; joining is by baptism and chrismation.

Who leads, and who is allowed to.
The church got its first Ethiopian patriarch in 1959, after sixteen centuries of Egyptian bishops. Since then its leadership has been contested by every Ethiopian government in turn, and in 2023 by a rival synod claiming the Oromo-speaking dioceses.

The whole quarrel may have been about words.
In 1990 the joint commission of the two Orthodox families signed a statement at Chambesy saying both had always held the same christological faith in different vocabularies. Bishops on both sides signed. Monasteries on both sides declined to act on it, and no communion has followed.

One church, two thrones.
The Catholicos of All Armenians sits at Etchmiadzin and the Catholicos of the Great House of Cilicia at Antelias in Lebanon. Both consecrate bishops and bless the Muron; Etchmiadzin holds primacy of honour. The arrangement is medieval in origin, hardened by the Cold War, and it still produces jurisdictional quarrels in the diaspora — most visibly in North America, where two parallel dioceses cover the same cities.

Thomas came here in 52, and we stayed with Rome.
The Syro-Malabar Church holds the same apostolic tradition as every Saint Thomas Christian body in Kerala, and it is the part of that community that remained in communion with Rome after the split of 1653. It is now the second-largest Eastern Catholic church in the world.

Who decides how the church prays.
A synod of bishops legislates for the whole church; an archdiocese of five hundred thousand said no for four years. The compromise reached in June 2025 gave each side part of what it wanted and settled the question of who has the last word by not answering it.

We never broke communion with Rome.
The Maronite Church is the only Eastern Catholic church with no separated counterpart — there is no Maronite Orthodox church — and it holds that it has been in communion with Rome without interruption since antiquity. The Latin chronicler William of Tyre wrote that the Maronites returned from monothelitism in 1182, and a good many historians accept some version of that; the church does not.

Thomas came here in 52.
The church holds that the apostle Thomas landed at Kodungallur in AD 52, founded seven and a half churches along the Malabar coast, and was killed at Mylapore near Madras in 68. The tradition is old and continuous in Kerala; outside historians treat the second-century Acts of Thomas as legend and the Indian Christian presence as securely attested from about the third century onward.

The Catholicos of the East sits in India.
The Catholicate was re-established at Niranam in 1912 and the church has governed itself under its own constitution since 1934. The Jacobite Syrian Christian Church contests exactly this: it holds that the Patriarch of Antioch retains authority over the Malankara church, and Indian courts have been deciding between the two positions since the nineteenth century.

The same faith, under its own patriarch.
Nothing in the Eritrean church's doctrine differs from the Ethiopian or the Coptic: one incarnate nature, the eighty-one book canon, the Ge'ez liturgy, the tabot. What changed in the 1990s was jurisdiction, not confession.
Go deeper — context →
Jacobite is a word from outside.
The church calls itself the Syriac Orthodox Church of Antioch and All the East. Jacobite comes from Jacob Baradaeus, the sixth-century bishop who travelled in disguise ordaining clergy after the imperial church deposed its hierarchy — a rescuer, not a founder. The church accepts him and rejects the label; in India, where the name became a legal designation, the argument is still live.

The Patriarch of Antioch is the head of the church in India.
The Jacobite Syrian Christian Church is the Indian archdiocese of the Syriac Orthodox Church, in communion with and under the Patriarch of Antioch and All the East, with a Catholicos in India since 2002 acting under him. Everything else — the Qurbana of Saint James, the fifty-day Lent, the Saint Thomas tradition — it holds in common with the church it is at law with.

Antioch decides.
The ordination oath binds clergy to the Patriarch of Antioch, and the Catholicos in India holds office under him rather than independently of him. This is precisely the point on which the two Malankara churches divide, and neither side treats it as a technicality: for one it is the guarantee of apostolic continuity, for the other it is foreign control of an Indian church.

Reformed, and still Eastern.
The church kept the West Syriac liturgy, the threefold ministry of bishop, priest and deacon, the church year and the fasts, and changed the theology inside them. It calls itself Reformed Oriental and is in full communion with the Anglican churches and with the Church of South India, not with any Oriental Orthodox church.

Communion with Rome, without becoming Latin.
The Chaldean Church holds Catholic doctrine and papal primacy and keeps the East Syriac rite: the Qurbana of Addai and Mari, the Hudra, married parish clergy, and a liturgical Syriac older than Latin. Rome's repeated attempts to Latinise the rite were reversed in the twentieth century, and the reformed Chaldean liturgy of 2005 went further back rather than further west.

A patriarchate in transition.
Cardinal Louis Raphael Sako led the church from January 2013 and resigned on 9 March 2026, having said for years that he intended to go at seventy-five. The synod meeting in Rome elected Amel Shamon Nona on 12 April 2026; he took the name Paul III and was enthroned in Baghdad on 30 May.

Reunion, or departure.
Rome and this church call 1930 a reunion — a return to a communion broken in the seventeenth century. The Malankara Orthodox Syrian Church calls it the departure of a metropolitan who took part of a diocese with him. The facts are agreed; the word is not.

Nestorius is not our founder.
The church did not derive its theology from Nestorius, who was a Greek bishop of Constantinople it never had jurisdiction over; it received the Antiochene tradition directly, through the school of Nisibis. It has never accepted the condemnation of 431 and never taught that there are two Christs. Nestorian, as a name for this church, is a label its neighbours applied.

The see came home in 2015.
For most of the twentieth century the head of the Church of the East lived in the United States, the patriarchate was hereditary within one family, and the church split twice. All three of those facts have since been undone.

Leadership was appointed, not chosen.
Shia Islam holds that God designated Ali, and through him a line of Imams: the imamate is an article of faith, not a political arrangement. Sunni Islam holds that the community chose, and chose rightly. Nearly everything else that separates the two follows from this one disagreement.

The Celestial Masters, and the argument about who is one.
The office has passed by descent in the Zhang family for a claimed sixty-four generations. The 63rd fled to Taiwan in 1949 and died in 1969 without an undisputed successor, and rival claimants have been recognised by Taiwan, by mainland bodies and by different branches of the family ever since. The ancestral seat at Mount Longhu is in Jiangxi.

passages a tradition marks as contested inside itself — the disagreement is theirs, not ours
The splits.
451 over how to say Christ is one person; 1054 between Rome and Constantinople; 1517 across the West. The 1054 excommunications were mutually lifted in 1965 and the churches still do not share communion, which shows how little the formal gesture settles.

Women and ordination.
The Church of England ordained women priests in 1994 and bishops in 2014; most mainline Protestant churches did so earlier. Rome holds the question closed. The Orthodox churches are re-examining the ancient order of deaconesses, which existed and then stopped, and nobody quite agrees why.
