What are the languages of Scriptures in Christianity?

There are many! The Holy Scriptures themselves were mainly written in Ancient Hebrew and Ancient Aramean (though it was only true for a minority of scrolls, but aramean is a very important language in the Talmud), then The Bible was translated into Latin, creating the Vulgate, that became the basis for religious study in West Europa; then came further translations: middle high German, middle English, middle French... There was also a Greek translation (the Septuagint), that the Orthodox Church used... The other great Orthodox country, Russia, used the Old Slavonic language for liturgy.
