Eh, why were the autographs and manuscripts in Greek then.
“Eh, why were the autographs and manuscripts in Greek then.”
Show me the autographs. Oh, that’s right, you can’t because no one alive has ever seen them and everyone - AND I MEAN EVERYONE - believes they were lost or destroyed at least 1500 or 1600 year ago if not even earlier. The Apostles wrote in the languages they knew to people they knew could read them in the languages they were written in or translated into. There’s plenty of reason to believe some NT books were written in Hebrew or Aramaic. Got some money? http://www.amazon.com/The-Hebrew-Christ-Language-Gospels/dp/0819908762/ref=pd_sim_sbs_b_1
Got a lot less money? http://www.amazon.com/Gospel-Of-Matthew-Translation-Notes/dp/0931888654/ref=pd_sim_sbs_b_1
And somewhere in between: http://www.amazon.com/Birth-Synoptic-Gospels-Jean-Carmignac/dp/0819908878
Also, think of the audience the Apostles were writing to generally speaking: people mostly in the lower classes, or in the eastern half of the Roman Empire. They spoke Greek in their homes and in most businesses. People in the Western half of the Empire generally spoke Latin. When Paul was writing to the Romans he was generally writing to people from the lower classes - Greek speaking slaves - or even educated people who would have received what we would have called a classical education which included - you guessed it - Greek. There were also Greek speaking colonies in the West. Lyons was still speaking Greek (and Latin) in the third century A.D. for instance.
Because the Greeks were the most recent conquerors/ inhabiters of the area prior to the Romans and it was a common language. You do recall that even the OT had been translated into Greek in the Septuagint.
