We often hear things similar to the following:
There is no such thing as a gentile christian or a jewish christian. We are all one in Christ. Prior to Christ, you were either jewish or gentile, but not after: “For as many of you as were baptized into Christ have put on Christ. There is neither Jew nor Greek….” Gal. 3:27-28 Colossians 3 also backs this up.
If this manner of thinking regarding Jew and Gentile was correct, than according to the same passage there is also no more male or female.
Paul’s language in this case was intended to be understood spiritually speaking, not physically-speaking. Just as there are still male and female, there are still Jew and Gentile in the body of Messiah.
However, whereas many of the Jews in the first century believed only those Jewish after the flesh (physically speaking) could be assured of a place in the world to come, Paul is emphasizing that there is no longer (spiritually speaking) Jew and Gentile in Messiah, but one Body and that all who believe have equal access to the Father. All who believe are sons of Abraham and adopted into the “commonwealth of Israel”.
