There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus. Galatians 3:28.  New International VersionSome of us are Jews, some are Gentiles, some are slaves, and some are free. But we have all been baptized into one body by one Spirit, and we all share the same Spirit.

1 Corinthians 12:13. New Living TranslationHere there is no Gentile or Jew, circumcised or uncircumcised, barbarian, Scythian, slave or free, but Christ is all, and is in all.

Colossians 3:11. New International VersionAs the time approached for him to be taken up to heaven, Jesus resolutely set out for Jerusalem. And he sent messengers on ahead, who went into a Samaritan village to get things ready for him; but the people there did not welcome him, because he was heading for Jerusalem. When the disciples James and John saw this, they asked, “Lord, do you want us to call fire down from heaven to destroy them?” But Jesus turned and rebuked them. Then he and his disciples went to another village.

Luke 9:51-56  New International VersionA dispute also arose among them as to which of them was considered to be greatest. Jesus said to them, “The kings of the Gentiles lord it over them; and those who exercise authority over them call themselves Benefactors. But you are not to be like that. Instead, the greatest among you should be like the youngest, and the one who rules like the one who serves.

Luke 22:24-26. New International Version
