Who was the first person to translate the Holy Bible in the common man’s language?
The Old Testament was originally written in Hebrew, the language of the Jewish people. Several hundred years BC, a group of Jewish scholars translated these scriptures into Greek.
Why Greek? Well, Greece was a major Mediterranean power and Alexander the Great conquered the entire Mediterranean in the 300s BC. Greek became the language of that entire region because it was the language of the rulers. Greek was the language of literature, commerce, law, business, etc for hundreds of years.
The New Testament was written in Greek because it was the common language of the entire Mediterranean. It was the language of all the educated people. Most Jews were bilingual, speaking Greek and Aramaic, and writing/reading Hebrew.
The Roman Empire began expanding, and the educated classes of Rome also spoke/wrote/read Greek. Over time, Latin became dominant.
So, by the 300s and 400s writing in the West was mainly in Latin. That is when St. Jerome translated the Bible from Greek into Latin. Latin remained the language of the educated classes for centuries.
Additionally, many, many priests and missionaries translated Scripture into hundreds of languages as they evangelized.
As far as I have heard the Rome used the Holy Bible in Latin, but now we have it in so many languages, which makes us common people read it with ease.
The “common people” of the Roman Empire spoke, read, and wrote Greek and Latin.
The missionaries going out into the territories translated into other languages. For example, Sts. Cyril and Methodius actually *created *the Cyrillic alphabet (the alphabet used in Russian and other Slavic languagegs) in order to transcribe the Bible into the slavic languages.
Why was it in Latin / greek earlier
Because those are the languages everyone read and spoke
and who defied the rule to have it changed?
No one “defied” anyone. There was no rule regarding the language of the Scriptures.
They began in Greek because that was the language spoken in first century Palestine and the Mediterranean region. They were translated into Latin because that became the language everyone read/spoke in the 300s and 400s. They were translated into various languages as Christian missionaries went out evangelizing and spreading the gospel. The Scriptures continued to be translated into various languages as they developed over time.
The Scriptures were in Latin for a very long time, and can still be found in Latin, because that was the common language that united ALL of the Roman Empire.
I’m not really understanding your question. What language would you have expected the Scriptures to be in during the first centuries?
