[7] It became a vessel for the development of a distinctive Syriac form of Christianity which flourished throughout the Near East and other parts of Asia during Late Antiquity and the Early Medieval period, giving rise to various liturgical and denominational traditions, represented in modern times by several churches which continue to uphold the religious and cultural heritage of Syriac Christianity.
[1] The area where Syriac or Aramaic was spoken, an area of contact and conflict between the Roman Empire and the Sasanian Empire, extended from around Antioch in the west to Seleucia-Ctesiphon, the Sasanian capital, in the east and comprised the whole or parts of present-day Syria, Lebanon, Israel/Palestine, Iraq, and parts of Turkey and Iran, with its speakers being largely Semitic Assyrians, Arameans, Phoenicians and Judeans.
[20] Since the proposed distinction is not yet universally accepted among scholars, its individual and often inconsistent application has created a complex narrative, that is additionally burdened by older problems, inherited from terminological controversies that originated much earlier, within Syriac studies in particular, and also within Aramaic studies in general.
The ruins of the Dura-Europos church, dating from the first half of the 3rd century are concrete evidence of the presence of organized Christian communities in the Aramaic-speaking area, far from Jerusalem and the Mediterranean coast, and there are traditions of the preaching of Christianity in the region as early as the time of the Apostles.
However, "virtually every aspect of Syriac Christianity prior to the fourth century remains obscure, and it is only then that one can feel oneself on firmer ground".
[29] The fourth century is marked by the many writings in Syriac of Saint Ephrem the Syrian, the Demonstrations of the slightly older Aphrahat and the anonymous ascetical Book of Steps.
[31] Two councils held in the following century divided Syriac Christianity into two opposing parties.
[34] Since those three theologians were highly regarded among Eastern Syriac Christians, further rifts were created, culminating in 612, when a major council of the Church of the East was held in Seleucia-Ctesiphon.
Presided by Babai the Great (d. 628), the council officially adopted specific Christological formulations, using Syriac term qnoma (ܩܢܘܡܐ) as designation for dual (divine and human) properties within one prosopon (person) of Christ.
The East Syriac Rite is noted especially for its eucharistic Qurbana of Addai and Mari, in which the Words of Institution are absent.
[40] Patriarch Timothy I of the Church of the East declared: "And also in all the countries of Babylon, of Persia, and of Assyria, and in all the countries of the sunrise, that is to say, among the Indians, the Chinese, the Tibetans, the Turks, and in all the provinces under the jurisdiction of this Patriarchal See, there is no addition of Crucifixus es pro nobis".
The majority of the Saint Thomas Christians, who initially depended on the Church of the East, maintained union with Rome in spite of discomforts felt at Latinization by their Portuguese rulers and clergy, against which they protested.
A reunion movement led in 1930 to the establishment of full communion between some of the Malankara Syrian Orthodox and the Catholic Church.
[44][45] Indigenous Aramaic-speaking communities of the Near East (Syriac: ܣܘܪܝܝܐ, Arabic: سُريان)[46] adopted Christianity very early, perhaps already from the first century, and began to abandon their three-millennia-old traditional ancient Mesopotamian religion, although this religion did not fully die out until as late as the tenth century.
[citation needed] The kingdom of Osroene, with the capital city of Edessa, was absorbed into the Roman Empire in 114 as a semi-autonomous vassal state and then, after a period under the supremacy of the Parthian Empire, was incorporated as a Roman province, first in 214, and finally in 242.
As a result, several Evangelical groups have been established, particularly the Assyrian Pentecostal Church (mostly in America, Iran, and Iraq) from East Syriac Christians, and the Aramean Free Church (mostly in Germany, Sweden, America and Syria) from West Syriac Christians.
