The primitive Church
The first Christian Churches were founded either by an apostle or by an evangelist: the main Churches of the Roman Empire were those of Alexandria, Antioch and Jerusalem in the East, and Rome in the West.
The imperial Roman power persecuted Christians until the early 4th century: freedom of Christian worship in the Roman empire was acknowledged by the edict of Milan in 313.
The Church in Constantinople became especially important after 330 when Emperor Constantine chose Byzantium as the capital city, under the name of Constantinople.
In 391, by the will of Emperor Theodore, Christianity became the official religion of the Roman Empire.

The Christians and the first schisms
From its onset Christianity underwent divisions. When theological discussions turned into quarrels, they caused breaks and schisms.
These Christians followed the teaching of Arius, a theologian in Alexandria in the 4th century. Arius insisted on God’s absolute transcendence. For him, the Son was created by God who passed his divinity on to him. So he was his subordinate.
Arianism was declared a heresy by the Council of Nicea summoned by Emperor Constantine in 325. Arianism spread over the Roman Empire for a while, then outside its borders among German tribes, notably the Visigoths, but progressively disappeared in the 7th century.
These Christians followed the teachings of Nestorius, a patriarch in Constantinople (381-451).
The Nestorians claimed that two beings co-existed in Jesus, one of human essence and the other of divine essence; for them Mary could not be called God’s mother: she was the mother of the man Jesus.
Their trend was rejected by the Council in Ephesus in 431.
The Nestorians then founded the ‘Church of the two councils’ as it acknowledged only the first two councils of Nicea and Constantinople.
These Christians followed the teachings of Eutyches and Disocorus of Alexandria.
The Monophysistes claimed that the Son Jesus was only of divine essence which had absorbed his human essence.
They split after the Council of Chalcedon of 451. They founded the ‘Churches of the three councils’, as they acknowledged only the first three ecumenical councils.
These churches were:
– The Coptic traditional Churches, namely the Coptic Orthodox Church, the Ethiopian Orthodox Church, the Erythrean Orthodox Church issued from the Ethiopian Orthodox Church in 1993;
– The Syriac traditional Churches, namely the Syriac Orthodox Church, the Malankara Orthodox Church…;
– The Armenian traditional Church, namely the Armenian Apostolic Church.
The term ‘Orthodox’ was chosen by some Churches of Monophysite origin, though they were not necessarily in communion with the Orthodox Church.
The first seven ecumenical councils
The Council of Nicea was the first ecumenical council summoned by the Emperor because of the controversies whichh split Christian communities and caused uprisings in the Empire.
The ecumenical councils were meetings to which all the bishops of Christianity were summoned. Because of the divisions some Churches or communities only acknowledged a reduced number of councils, depending on the period when they broke away. The first seven councils were acknowledged by both Orthodox and Romas Catholic Churches.

It condemned Arianism as a heresy; confession of faith and symbol of Nicea; unity and consubstantiation between the Father and the Son.

Progress in the tour
The branches of Christianity
Born in Palestine amongst Judaism, Christianity progressively established itself in the Roman Empire and then spread all over the world. It evolved along with a great doctrinal and ritual diversity: When disputes became too controversial, they caused schisms. Thus Christianity is a religion with many different branches.
The first schisms within Christianity
Christianity developed quickly in the Roman Empire with a lot of diversity. Disputes arose and were settled by ecumenical councils which defined the correct doctrine and condemned the others. They caused many schisms.
The ecumenical dialogue
From the early 20th century multiple bilateral and multilateral ecumenical relations were established between Christian Churches.
Filiation of the Christian confessions
From its beginnings Christianity was characterized by a great doctrinal and ritual diversity, which caused controversies and schisms. The two most important ones were the great East-West schism separating the Orthodox from the Catholics in 1054, then the Reformation that gave birth to Protestantism in 1517.
Over the centuries some Churches split up, others merged; in the today’s world there is a wide variety of Christian Churches.
During the 20th century an ecumenical dialogue between Christian Churches was established to promote union.
