The Question of the Greek New Testament

[Polaris]

When I was a student at Biola, a 4 year Christian university, the Bible  professors and theologians spoke of reading the NT in the original Greek.  For many years, this sounded cool. I couldn't do it, but it was cool, nonetheless.

In the past few years, though, something occurred to me.  Jesus wasn't Greek. Neither did he speak Greek. Matthew, Mark, Luke and John weren't Greek. Neither did they speak Greek.  Peter, Paul, James and Jude weren't Greek. Neither did they speak Greek. So how could an authentic NT have been originally written in Greek?

A lot of the Bible written after the Gospels and the Book of Acts was likely written in Ancient Greek because the people who were reading the letters of that time were in the Ancient Greek cities. Paul likely could speak Ancient Greek and Ancient Hebrew as well as Latin. I doubt he knew how to speak Aramaic, however.
