'''Koine Greek''' is the popular form of Greek which emerged in post-Classical antiquity (c.300 BC
– AD300), and marks the third period in the history of the Greek language. Other names are ''Alexandrian'', ''Hellenistic'', ''Common'', or ''New Testament'' Greek. Koine is important not only to the history of the Greek people, for being their first common dialect and main ancestor of modern Greek but also for its impact on the [[Orthodox ]] [[Church]] and the rest of the world. It was the original language of the [[New Testament]] of the [[Bible]] as well as the medium for the teaching and spreading of [[Christianity]] - ''unofficially the second language of the [[Roman Empire]]''.
'''[[Biblical Koine]]''' refers to the varieties of Koine Greek used in the Bible and its related texts. It is
usefull in the complete education of an Orthodox christian. Its main sources are:
* the [[Septuagint]];
[[New Testament ]], compiled originally in Greek (although some books may have had a Hebrew-Aramaic substrate and contain some Semitic influence on the language).
The term '''[[Patristic Greek]]''' is sometimes used for the Greek written by the [[Church Fathers]], the early Christian theologians in late antiquity. Christian writers in the earliest time tended to use a simple register of Koiné, relatively close to the spoken language of their time, following the model of the Bible. After the 4th century, when Christianity became the official state religion of the Roman Empire, more learned registers of Koiné influenced by asceticism came also to be used.
