Historically, both liturgy and theology varied, broken roughly by the boundaries between the greek-speaking eastern half of the empire, and the latin-ish speaking west.
There as an early document (āConstitution of the Twelve Apostlesā ? something like that . . .) with some general principals.
Liturgy varied widely, and āthe Bibleā had yet to be defined. At some point, the liturgy from one of the
other churches influenced and took over the liturgy in the capital, Byzantium. It spread and became normative throughout the eastern empire.
The West, on the other hand, didnāt have a uniform liturgy until Trent (prior to that, liturgy varied widely, although I think itās something like half that used the liturgy of Rome and in latin [well, once Rome switched to the vernacular over the third and fourth centuries . . .], but I wouldnāt even bet a cup of coffee on the āhalfā figure, in either direction).
Byzantine practice has
always held the liturgy in the vernacular, and it has always been the primary instructional tool in the faith. While Church Slavonic might
seem at first to be an exception, it (and the Cyrillic alphabet) was
created for the purpose of being mutually intelligible among the various Slavic people.
After the Great Schism, which actually took centuries to fully schis (schismatic? schismatify?
), the West was generally called āCatholicā, and the east āOrthodoxā.
There are also other regions that followed neither pattern, many (most?) outside of the boundaries of the empire.
The east had multiple churches geographically, with patriarchs, while the west had one. There was
never a time when the One, Holy, and Apostolic Church consisted of a single church, nor that it was all directly ruled from Rome.
Speaking in
very rough terms, and with these being generalizations, and not denying that both aspects were present in both churches . . .
- Western liturgy focuses on reenacting the Last Supper, while the East focus on the Kingdom of God and tries to join the celestial liturgy.
- Western theology is intent on explaining and finding detail; the East is perfectly happy with mystery to the point that it might be fairly claimed to prefer mystery to detail.
- The west takes a more judicial/legal approach to sin, while the east takes ore a medical approach
- The west has relatively more emphasis on the Crucifixion, the east on the Resurrection.
