And then we have the Muslims who believe Arabic is the language of God when all it was was the language of Mohammed and they will never adopt any other languages for worship even when the majority of their believers do not understand Arabic. Be careful how you dispose of anything written in Arabic, even the Divine Liturgy, you might be accused of "descration"

She is probably the old woman who told my dad, when complaining about English in the liturgy, "Father, OF COURSE I understand that Church 'slavish'. My baba taught me as a child! - you know, that Svatyj Boze, Svatyj Kripkjy song....That's all about Jesus breaking out of the crypt!" True story he loved to relate from his 66 years in the priesthood!

Constantine, born and raised in the west, was a native speaker of Latin, but, being the son of the Augustus Constantius Chlorus, he received an excellent classical education, which, naturally, included Greek. However, even among Western aristocrats, fluency in Greek was becoming rare by the end of the 4th century, while in the Eastern half fluency in Latin was declining rapidly. By the sixth century, each half of the Empire was essentially monolingual (though the pro to-Romance languages were rapidly making Latin incomprehensible among the lower classes). The Persian War at the beginning of the 7th century, followed by the Muslim invasions, led the Eastern Empire to officially make Greek the administrative language--clarity and efficiency had finally trumped tradition. The loss of Syria and Egypt meant that, for all intents and purposes, Greek was the only language in the Eastern Empire, while in the remnant of the West, Latin was spoken only by churchmen and a diminishing number of aristocrats.
