Galatians 2:14

2:14 But when I saw that they were not behaving consistently with the truth of the gospel, I said to Cephas in front of them all, “If you, although you are a Jew, live like a Gentile and not like a Jew, how can you try to force the Gentiles to live like Jews?”

Galatians 3:28

3:28 There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female – for all of you are one in Christ Jesus.
