The very racist separation of Jews and Gentiles, would not even exist without the bible and it's God. The bible is riddled with commandments and rules for slavery, never once condemning it, quite the opposite. As for the sexism in the bible, a good example being that a female slave was worth less and had to stay a slave longer..... Makes your chosen verse a mockery.
no offence, but I assume, this is why you didn't quote it, but instead gave a very biased interpretation.
the verse is saying, despite the difference between Jew and gentile, slave and free man, female and male, all are serving/ adhering to Jesus.
Had it been moral, the verse would have not separated people by race, sex and ownership. It would have said all these things are in fact immoral!
I am am amazed that you chose this verse, really.
