The Bible was first written in Hebrew, then Aramaic. The old Testament was written in parts in periods of time a thousand years or more. Then the New Testament was written within a hundred years after the time of Christ. It was written in Aramaic, the language Jesus spoke, or parts, especially written by Luke in Greek. The entire Bible was translated to Greek then later Lain. By somewhere around 300 AD (or now called C.E.) the Bible as it would be known in the Catholic Church was chosen, some works were thrown out. There are things like the "Gospel of Thomas" and some others not included in the Bible.
Then in the 1300's a man named Wycliffe (I'm not sure if I spelled that correctly) was considered a heretic for translating the bible into English, of course it was all Catholic then. Later, after the Protestant reformation, Luther translated the Bible into German and King James of Britain commissioned the Bible to be translated into English from Hebrew and Greek texts. Some books were taken out of the Protestant Bible and some were put in, such as Ecclesiastics are in the Protestant and not Catholic versions. The Catholic version was translated into the 'vernacular' or modern languages like English, from Latin in about 1800.
