Romans 1:14

14 I am debtor both to the Greeks, and to the Barbarians; both to the wise, and to the unwise.

Romans 3:9

9 What then? are we better than they? No, in no wise: for we have before proved both Jews and Gentiles, that they are all under sin;

Romans 10:12

12 For there is no difference between the Jew and the Greek: for the same Lord over all is rich unto all that call upon him.
