'Difference' in the Bible

Even the righteousness of God which is by faith of Jesus Christ unto all and upon all them that believe: for there is no difference:

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.

and he who is making a difference, if he may eat, hath been condemned, because it is not of faith; and all that is not of faith is sin.
