'Gentiles' in the Bible

while we proclaim a Christ who has been crucified--to the Jews a stumbling-block, to Gentiles foolishness,

It is actually reported that there is fornication among you, and of a kind unheard of even among the Gentiles--a man has his father's wife!

No, but that which the Gentiles sacrifice, they sacrifice to demons, not to God; and I would not have you have fellowship with one another through the demons.

Do not be causes of stumbling either to Jews or to Gentiles, nor to the Church of God.

For, in fact, in one Spirit all of us--whether we are Jews or Gentiles, slaves or free men--were baptized to form but one body; and we were all nourished by that one Spirit.
