{{main|Assyrian Church of the East}}
{{As of|2021|September|13|df=us}}, [[Awa III]] is the catholicos-patriarch of the Assyrian Church of the East. One of the oldest Christian churches, it is a modern successor of the historical [[Church of the East]]. It traces its origins to the See of Seleucia-Ctesiphon in central Mesopotamia, which tradition holds was founded by [[Thomas the Apostle]] as well as [[Mari of Edessa]] and [[Addai of Edessa]] in the year 33 as asserted in the [[Doctrine of Addai]].

It is one of the three churches of the East that hold themselves distinct from [[Oriental Orthodoxy|Oriental]] and [[Eastern Orthodox Church|Eastern Orthodoxy]]. It is often called the [[Chaldean Syrian Church]] in India. The church declares that no other church has suffered as many martyrdoms as the Assyrian Church of the East.{{Citation needed|date=July 2010}}

The founders of Assyrian theology were [[Diodorus of Tarsus]] and [[Theodore of Mopsuestia]], who taught at Antioch. The normative Christology of the Assyrian church was written by [[Babai the Great]] (551–628) and is distinct from the accusations directed toward [[Nestorius]]. Babay's main Christological work is called the ''Book of the Union'' and in it, he teaches that the two {{transliteration|syc|qnome}} (essences or [[Hypostasis (philosophy and religion)|hypostases]]) are unmingled but everlastingly united in the {{transliteration|syc|parsopa}} or [[hypostatic union]].{{Citation needed|date=July 2010}}
