Here's what the Bible says about racial discrimination:
John 4:7-9. "There came a woman of Samaria to draw water. Jesus said to her, 'Give me a drink.' (For his disciples had gone away into the city to buy food.) The Samaritan woman said to him, "How is it that you, a Jew, ask for a drink from me, a woman of Samaria?" (For Jews have no dealings with Samaritans.)"
1 Corinthians 9:20-23. "To the Jews I became as a Jew, in order to win Jews. To those under the law I became as one under the law (though not being myself under the law) that I might win those under the law. To those outside the law I became as one outside the law (not being outside the law of God but under the law of Christ) that I might win those outside the law. To the weak I became weak, that I might win the weak. I have become all things to all people, that by all means I might save some. I do it all for the sake of the gospel, that I may share with them in its blessings."
Galatians 2:11-14. "But when Cephas came to Antioch, I opposed him to his face, because he stood condemned. For before certain men came from James, he was eating with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. And the rest of the Jews acted hypocritically along with him, so that even Barnabas was led astray by their hypocrisy. But when I saw that their conduct was not in step with the truth of the gospel, I said to Cephas before them all, 'If you, though a Jew, live like a Gentile and not like a Jew, how can you force the Gentiles to live like Jews?'"
Galatians 3:28. "There is neither Jew nor Greek, there is neither slave nor free, there is neither male nor female, for you are all one in Christ Jesus."
Colossians 3:11. "Here there is not Greek and Jew, circumcised and uncircumcised, barbarian, Scythian, slave, free; but Christ is all, and in all."
Revelation 5:9. "And they sang a new song, saying, "Worthy are you to take the scroll and to open its seals, for you were slain, and by your blood you ransomed people for God from every tribe and language and people and nation."
And here's what it says about class discrimination.
Mark 12:42-44. "And a poor widow came and put in two small copper coins, which make a penny. And he called his disciples to him and said to them, 'Truly, I say to you, this poor widow has put in more than all those who are contributing to the offering box. For they all contributed out of their abundance, but she out of her poverty has put in everything she had, all she had to live on.'"
James 2:1-7. "My brothers, show no partiality as you hold the faith in our Lord Jesus Christ, the Lord of glory. For if a man wearing a gold ring and fine clothing comes into your assembly, and a poor man in shabby clothing also comes in, and if you pay attention to the one who wears the fine clothing and say, "You sit here in a good place," while you say to the poor man, "You stand over there," or, "Sit down at my feet," have you not then made distinctions among yourselves and become judges with evil thoughts? Listen, my beloved brothers, has not God chosen those who are poor in the world to be rich in faith and heirs of the kingdom, which he has promised to those who love him? But you have dishonored the poor man. Are not the rich the ones who oppress you, and the ones who drag you into court? Are they not the ones who blaspheme the honorable name by which you were called?"
Does that help?
