The word cannot be more specific in Galations 3:28. ' No male or female, all are one in Christ Jesus'. How much plainer can it be said?
Here is the verse. It seems to be speaking about all believers who accept Christ are all one in Christ. It is saying that all the believers in Christ are one regardless of gender, Jew or Greek that all believers are one in Christ Jesus.
26 For ye are all the children of God by faith in Christ Jesus. 27 For as many of you as have been baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither bond nor free, there is neither male nor female: for ye are all one in Christ Jesus. 29 And if ye be Christ's, then are ye Abraham's seed, and heirs according to the promise.
