Dalam [[Konsili Seleukia-Ktesifon]] tahun 410, Gereja di Timur menyatakan bahwa Uskup Seleukia-Ktesifon, ibu kota [[Kekaisaran Sasaniyah|Persia]], adalah pemimpin tertingginya. Kepala Gereja di Timur disebut "Metropolit Agung" di dalam surat keputusan Konsili Seleukia-Ktesifon, tetapi tidak lama kemudian disebut "[[Katolikos]] di Timur". Gelar [[batrik]] baru dipakai belakangan.<!--
Sama seperti Gereja-Gereja lain, Gereja di Timur memiliki rohaniwan-rohaniwan [[penahbisan|tertahbis]] dalam tiga jejang tradisional, yakni [[uskup]], [[imam]] (atau [[presbiter]]), dan [[diakon]]. Sama seperti Gereja-Gereja lain, Gereja di Timur menerapkan [[episkopal|tatanan keuskupan]], yakni pengelompokan umat menjadi [[keuskupan]]-keuskupan yang masing-masing dikepalai seorang uskup. Umat di tiap keuskupan masih dikelompokkan lagi menjadi [[paroki]]-paroki yang masing-masing dipimpin seorang imam. Keuskupan-keuskupan yang berdekatan dikelompokkan menjadi satu [[provinsi gerejawi|metropolia]] di bawah kepemimpinan seorang [[metropolit|uskup metropolia]]. Jabatan uskup metropolia adalah jabatan yang penting, karena dibebani tugas-tugas maupun wewenang tambahan. Berdasarkan hukum kanon, hanya uskup-uskup metropolit yang berhak [[konsekrasi|menguduskan]] (semacam abiseka) batrik.{{sfn|Wilmshurst|2000|p=21-22}} Batrik mengemban tugas memimpin [[kebatrikan|provinsi batrik]].
The Church of the East had, like other churches, an [[ordination|ordained]] clergy in the three traditional orders of [[bishop]], [[priest]] (or [[presbyter]]), and [[deacon]]. Also like other churches, it had an [[episcopal polity]]: organisation by [[diocese]]s, each headed by a bishop and made up of several individual [[parish]] communities overseen by priests. Dioceses were organised into [[Ecclesiastical province|provinces]] under the authority of a [[metropolitan bishop]]. The office of metropolitan bishop was an important one, coming with additional duties and powers; canonically, only metropolitans could [[consecration|consecrate]] a patriarch.{{sfn|Wilmshurst|2000|p=21-22}} The Patriarch also has the charge of the [[Patriarchate|Province of the Patriarch]].

{{main|PeshittaPesyita}}<!--
The [[PeshittaPesyita]], in some cases lightly revised and with missing books added, is the standard [[Syriac versions of the Bible|Syriac Bible]] for churches in the Syriac tradition: the [[Syriac Orthodox Church]], the [[Syriac Catholic Church|Syrian Catholic Church]], the [[Assyrian Church of the East]], the [[Ancient Church of the East]], the [[Chaldean Catholic Church]], the [[Maronites]], the [[Malankara Orthodox Syrian Church]], the [[Syro-Malabar Catholic Church]] and the [[Syro-Malankara Catholic Church]].
The [[Old Testament]] of the Peshitta was translated from [[Hebrew language|Hebrew]], although the date and circumstances of this are not entirely clear. The translators may have been Syriac-speaking Jews or early Jewish converts to Christianity. The translation may have been done separately for different texts, and the whole work was probably done by the second century. Most of the [[Biblical apocrypha|deuterocanonical books of the Old Testament]] are found in the Syriac, and the [[Wisdom of Sirach]] is held to have been translated from the [[Hebrew]] and not from the [[Septuagint]].<ref>[http://www.bible-researcher.com/syriac-isbe.html Syriac Versions of the Bible by Thomas Nicol]</ref>
