Was Luke the only non-Jewish writer in the Bible?

Answer 1

It appears that Luke was not Jewish, however scholars now say that he wrote none of the books in The Bible. He is traditionally credited with writing the gospel that now bears his name, as well as Acts of the Apostles. However, these books were originally anonymous and were only attributed by the Church Fathers to Luke later in the second century. The main reason for that attribution seems to have been the polished Greek language used, and Luke was the only apostle they knew of with the necessary education. Naturally they assumed that these books were written around the middle of the first century, within the lifetime of Luke, but scholars now say that they were actually written at the end of the century or early in the second century.

We do not know who really wrote Luke's Gospel, so we do not know whether or not he was Jewish. Since we also do not know who wrote any of the other gospels, we can not say how many were written by Jews or non-Jews.

Answer 2

King Nebuchadnezzar wrote a section of Daniel.
